00:00 Quantum science is exploding in the 21st century.
00:03 Whether it's researchers redesigning the atom, applying it to a revolution in quantum computing,
00:08 or even developing real-life superpowers via subatomic means,
00:12 it's clear that quantum physics and mechanics are now a guiding light to lead humanity into the future.
00:18 In this video, we'll take a closer look at the incredible history that's taken us to this point.
00:24 We'll also explore the mind-bending wider theory of the microverse and its potential applications,
00:30 including for time travel, that could really change the world.
00:34 And finally, we'll imagine what life might actually be like if we ever move into the quantum realm ourselves.
00:41 This is Unveiled, and today we're answering the extraordinary question;
00:45 is quantum science about to change everything?
00:48 Do you need the big questions answered? Are you constantly curious?
00:52 Then why not subscribe to Unveiled for more clips like this one?
00:55 And ring the bell for more thought-provoking content!
00:57 Everything is made of atoms. It's something that we all know within ourselves,
01:06 but it perhaps isn't something that we really stop to think about very often.
01:10 And it's certainly a tricky concept to wrap our minds around.
01:13 That everything, everywhere, has an atomic structure that we can't actually see,
01:17 but that's also vital and fundamental to that thing's very existence?
01:21 How, then, with seemingly nothing to go on,
01:24 did the first formulators of the atom come to that particular conclusion?
01:28 To watch this video, you're looking at a screen. But, actually, all you're really taking in is atoms,
01:43 arranged in a very particular way. Look away from your screen and you might see a book, an apple,
01:47 a swimming pool, a rhinoceros, anything… and it's exactly the same deal. Certain atoms, built and
01:53 arranged in certain ways so that, on our level, we understand them as whatever it is that they've
01:58 amalgamated to be. But, of course, the atomic structure of something - be that the water you
02:02 drink, the atmosphere you breathe, the cake you bake, and so on - is always key. Underneath it
02:08 all, even you yourself are only atoms. Human beings are an especially complex mass of atoms,
02:13 yes, but still, that's all that we really are. In the old days, stereotypically wise figures
02:18 might have dabbled in alchemy. In short, alchemy was like an attempt to try to control atoms,
02:23 even before the discovery of them, and mostly to try to turn one thing into something else.
02:28 Usually gold, but that's besides the point. Because today, broadly, we know that same pursuit,
02:34 that same attempted mixing up of materials, as chemistry. And in the modern world, we really
02:39 can break down all or most materials into their fundamental parts, and even in some cases we can
02:45 rearrange them. Again, it's merely a case of having the right atomic knowledge - no alchemy
02:50 needed. But still, we've only had this level of knowledge for the past century or so, and it's
02:56 been a long time coming. Theories on a base level of matter do date back far earlier, to the times
03:01 of Ancient Greece, and particularly to one 5th century BCE philosopher, Democritus. He wrestled
03:08 with an idea. If you have something, and cut it in half, and then half again, and then again,
03:14 and again, and again, indefinitely… would you eventually reach a point where what was left could
03:19 no longer be cut? Would you eventually reach a kind of starting point for matter? A base unit,
03:25 below which it was impossible to go? This hypothesised unit was then labelled an atom,
03:31 with the word deriving from the Greek "atomos", which means "uncuttable" or "indivisible".
03:36 However, from there, this really revolutionary idea was effectively shelved for a couple of
03:41 thousand years. It's not until the early 1800s that atomic theory properly takes hold again,
03:47 thanks mostly to one John Dalton. His most famous contribution to science is the Law of
03:52 Multiple Proportions, otherwise known as Dalton's Law, first put forward in 1804. Through it,
03:57 Dalton realised that the masses of simple chemical compounds could always be reduced back down into
04:03 ratios with small whole numbers. More simply, Dalton was able to show that whenever, say,
04:09 oxygen were present, it was possible to calculate how many parts or units of oxygen there were,
04:16 based on mass. The structure of a compound, although far too small to be seen, could always
04:21 be determined. The difference between, for example, carbon monoxide and carbon dioxide
04:26 could now be explained. Dalton didn't have it all correct from the beginning, though.
04:31 At this stage, it was still thought that there was nothing smaller than the atom.
04:34 But we now know that that's wrong. We know, for instance, that an atomic nucleus is made up of
04:39 protons, neutrons and electrons - subatomic objects that further serve to differentiate
04:44 one element from the next, from the next. But, still, Dalton's work is widely held to be the
04:49 beginning of atomic theory. He picked up from where the ancient philosophers left off, and built
04:54 a base from which emerging physicists could work and experiment in the nineteenth and twentieth
04:58 centuries. Unsurprisingly, and almost exactly one hundred years after Dalton's law was introduced,
05:04 Albert Einstein enters the fray. In fact, Einstein's explanation of something called
05:08 "Brownian motion" - the seemingly random movement of particles when suspended in water or gas - goes
05:14 down as one of his first major scientific achievements. Einstein suggested that Brownian
05:19 motion was quite simply caused by the movement of countless other and smaller particles that
05:24 surrounded the larger and more noticeable ones. This, again, was something of a game-changer,
05:30 as it encouraged us to think not just of objects but of reality as a whole, as though it were one
05:35 swirling, connected, interacting mass of atoms. Which, ultimately, it is. Visual depictions of
05:42 Brownian motion are somewhat headache-inducing, but that's what makes it all the more incredible
05:46 that this almost vibrating hum of particles should be happening all the time, all around us.
05:51 From the late 1800s through to the First World War, physicists including J.J. Thompson,
05:56 Ernest Rutherford, and Niels Bohr worked to incorporate the newly discovered electron
06:01 (discovered by Thompson) into the then-ever-changing model of what an atom actually looked like.
06:07 By the time of the Second World War, that model had been put to such use that we were now capable
06:11 of splitting the atom via nuclear fission - the most infamous result of this being the advent of
06:16 the nuclear bomb. Around this time, and especially with the war effort on both sides driving
06:21 research forwards, a number of high-profile scientists were involved in the development
06:25 of nuclear physics, including still Albert Einstein, plus Enrico Fermi, Leo Szilard,
06:31 and Robert Oppenheimer. Unsurprisingly, and mostly due to the bomb, experimentation with atoms became
06:37 something that some people feared post-World War Two. One of the difficulties was that,
06:41 although high-ranking physicists now understood the atom better than ever before, it remained
06:46 something of a mysterious commodity for everyone else watching on. As we move through the 21st
06:51 century, much of that fear factor has disappeared - perhaps simply because subatomic study is such
06:56 a standard backdrop to contemporary life. Although, that said, we do still see various
07:02 examples of rising panic, such as when the Large Hadron Collider was first switched on at CERN.
07:07 And many worried that it would instantly create a black hole on Earth and spaghettify us all into
07:11 an early death. Thankfully, that didn't happen, and subatomic science has now fully made its
07:16 latest jump into quantum mechanics. If the atom is hard to visualise, then the quarks and leptons
07:22 of the subatomic quantum realm are even harder. But, thanks to the standard model of elementary
07:27 particles, we do at least have a structure to refer back to. The model is being continually
07:32 updated, as researchers make more and more breakthroughs as the result of work at facilities
07:37 like the LHC… with one of the most famous achievements in modern times being the successful
07:42 detection of the Higgs boson, the so-called "god particle", in 2012. It makes you wonder,
07:47 what would John Dalton make of today's advancements? No matter how much more we achieve,
07:51 however, perhaps nothing will eclipse the scale of the shift uncovered by the likes of Dalton,
07:56 from the early eighteenth century onwards. Before atomic theory, we didn't yet know quite how much
08:01 of a mystery the physical world really was to us. We were largely ignorant to its inner workings.
08:07 There had, of course, been countless methods and tricks discovered wherein the chemical
08:11 make-up of our surrounding materials were already being manipulated. We see it in the cooking of
08:16 meals, the making of drinks, the building of houses, towns and cities… whenever anything,
08:22 any object - material, liquid or gas - is altered on a macro-visual level, there's some kind of
08:27 atomic restructuring taking place down below. But those early scientists were the first to
08:33 truly grasp this, and their realisation forced us all to view reality itself completely differently.
08:39 Now we're busy fleshing out even lower levels via the Standard Model, but still,
08:43 the atom itself was the original and greatest watershed moment. A before and after point in
08:49 time, from which we launched into an all-new age for science and technology.
08:54 As with astronomy, where we can see and understand more of the universe thanks to bigger and better
09:03 telescopes, our microscopes are now improving at such a rate that whole new worlds are appearing
09:08 to us inside of atoms. With the discovery of the quantum level, we've even had to develop a new set
09:13 of physics to make sense of it all… but how small can we really go? And does the journey ever end?
09:19 Simply put, the microverse is the idea that there are other planes, other universes,
09:33 existing at the micro-level within our own universe. If we zoom in on a particular molecule,
09:38 we can go close enough to see the atoms that make it up… with scientists once believing that that
09:43 was it. Atoms were the smallest possible parts of nature. We now know that if we go further,
09:48 we see the nucleus of that atom… further still for the neutrons and protons that make up that
09:53 nucleus. Here, again, was one time accepted as "the end" - the smallest we could possibly get.
09:59 But, we're now well aware that those neutrons and protons are also formed by other, smaller pieces;
10:04 quarks held together by gluons. Thanks to relatively recent experiments, we also know
10:09 that if you try to separate two quarks from each other, the energy it takes to do so can birth
10:13 completely new quarks in the process, leading some to see the quantum level as limitless.
10:18 Which brings us to the microverse theory; a kind of mirror image to the regular multiverse theory,
10:23 which says that if you were to somehow reduce your own size infinitely, you'd eventually find
10:28 yourself inside of an entire universe inside of an atom. The rule could hold true for every atom,
10:34 too, meaning that there are near-infinite universes thriving at the micro-level.
10:38 Nowadays, it's a go-to theme for modern sci-fi and pop culture, featuring in the Marvel comics
10:43 and on shows like Rick and Morty, where whole galaxies, planets and perhaps even living beings
10:48 could all exist within a particle. Thinking the other way, there's even the possibility that we
10:53 ourselves exist inside what's little more than a single particle inside someone else's much larger
10:58 universe. The microverse works two-fold; you can go either up and up, expanding outwards,
11:04 or down and down, reverting inwards. For some, it's absurd, and the idea definitely is hypothetical.
11:10 But while it may seem impossible that so much matter could fit inside such a small point,
11:15 consider that the universe isn't what it seems. All of the visible matter we can see only accounts
11:20 for around four percent of our total universe. Atoms have a similar make-up; they're 99.9%
11:25 empty space. Electrons exist in a cloud around the nucleus, which is around 100,000 times smaller
11:32 than the atom itself. But in the space in between, there seems to be complete nothingness.
11:37 To look at it another way, if we were able to push the matter that makes up your body so close
11:41 together so as to eliminate that empty space, we'd each be compressed down into the size of a tiny
11:46 speck of dust. So, what if we did something similar for an entire universe? Everything
11:51 condensed to the size of a single atom? Well, conventional physics says that we'd probably get
11:56 a black hole, as the smallest possible thing in the universe is thought to be the singularity at
12:00 the centre of a black hole; a place so dense that it bends spacetime infinitely to a smaller and
12:05 smaller point. According to the microverse theory, though, such inconceivable processes could be
12:11 happening all over the place, all of the time. And given that it's also theorised that when
12:15 black holes collapse they're able to birth whole new universes, this, too, is theoretically happening
12:20 all across reality at any available second. In one relatively traditional, though still totally
12:25 hypothetical idea, it's argued that our own "Big Bang" creation of the universe could have been
12:30 the result of a higher-dimensional star collapsing into a black hole. That's one theory for how
12:35 everything we've ever known came into being, but the microverse says that similar, spectacular
12:40 creations might be happening all of the time, just on a much smaller scale. At the very least,
12:45 they could be happening inside of other black holes that we know about. Of course, none of this
12:49 is proven. And if we ever did prove it, then it'd signal a major shift in how we think of and
12:54 appreciate the experience of life. As we've already found at the quantum level, widely accepted laws
13:00 of physics can be completely thrown out. There's no saying that any microverse universe should look
13:05 or behave even comparatively close to our own… but if there are infinite variations, then there
13:10 are also microverse set-ups that we would recognise. A strange aspect of modern science is that
13:15 classical mechanics perfectly explains everything we can see about the world… as long as we don't
13:20 go too large or too small. When you go too big, you need general relativity to work things out;
13:26 when you go too small, you need quantum mechanics. The rules of the game can change in either
13:30 direction, and maybe continue to change the further out or in you go. While we could well
13:35 be part of something much larger, we could also be part of something much smaller.
13:39 Clearly, there are some major question marks surrounding the microverse theory. For one,
13:44 wouldn't we just know about it? If everything we knew is made up of endless other clumps of
13:48 endless matter, wouldn't we be able to detect the mass or see the black holes? Maybe not when
13:53 we consider the Higgs boson, or what some term the "god particle". The Higgs boson shocked the
13:58 scientific community when it was discovered, because it proves the Higgs field - a fundamental
14:03 concept which is somehow able to give particles mass when they pass through it. It's even been
14:08 suggested that a Higgs field is what ultimately gave our own universe its mass… but before it
14:12 passed through the field, it was nothing. On a micro-level, waiting for an incredibly far-out
14:17 moment of revelation, other universes - or potential universes - could exist inside of
14:22 the atoms of our own. But, with no detectable mass from our perspective, because they don't
14:27 interact with anything like the Higgs boson or the Higgs field… this variation pitches the
14:31 microverse as though it's an untapped source, laying dormant because that's the way reality
14:36 panned out. But, regardless of how it's structured, there is a totally different world down
14:40 there at the subatomic level; a place wholly unknowable to human eyes, with completely different
14:46 rules but also some striking similarities with the universe as we know it. More than that, though,
14:50 if you stretch the theory far enough, then everything that we know could also be a subatomic
14:55 speck of nothingness on the fingertips of another, higher power.
14:58 What do you hope technology will achieve in the future? There are so many challenges and
15:09 possibilities that lay ahead for humankind… but of all the sci-fi superpowers that we could
15:16 develop, time travel surely ranks high in terms of its potential to change the world forever.
15:24 So, are we almost ready to finally make that breakthrough?
15:29 The debate surrounding time travel is as old as, well, time. For decades, even centuries,
15:47 humanity has been considering whether it could ever be possible to move not only through our
15:53 spatial plane, but also through a temporal one as well, more so than just into the future one second
16:01 at a time. Rather, we're after true, four-dimensional living, where the past is never
16:08 truly over and the future is always worth a visit. The flux capacitors of Hollywood films have
16:16 certainly inspired imaginations over the years, with the quest for time travel almost inevitably
16:22 bleeding over into the race to achieve faster-than-light movement. But now, with arguably
16:28 a new age of technological exploration only just beginning, have we finally found the key
16:36 to open this particular door? Theories surrounding quantum physics are hardly new news in
16:43 themselves. For much of the 20th century, scientists were busily getting to grips with the
16:49 subatomic realm, describing atoms, splitting atoms, and discovering all of the even smaller
16:56 parts that make even the atoms themselves look like vast and complicated structures.
17:02 Today, the quanta, the tiniest packets of reality, are reasonably well-known, and though the
17:10 standard model remains an incomplete and ever-evolving concept, we're now putting it to
17:16 practical use in the here and now macro world, with quantum computing. This is something we've
17:24 covered in previous videos, but to recap briefly, because actually, it could actually be crucial to
17:30 the question of time travel specifically. While traditional computers carry standard, binary
17:37 bits of information understood as ones and zeros, the quantum bits, or qubits, in quantum computers
17:45 can be either a one or a zero. This freedom dramatically expands the processing power they
17:53 offer, and it's here where the genuine possibility for time travel comes in, because some believe
18:00 that quantum computing will actually be powerful enough to bend and break the rules of time.
18:08 We already know that at the quantum level, the laws of physics somewhat fall apart.
18:14 Quantum entanglement enables apparent speed of light travel. Quantum data can easily move
18:20 between wave and particle states. Quantum superposition enables chunks of subatomic
18:26 information to apparently be in two places at once. We know that all of that's already true.
18:34 So, next stop, traveling back into the past, and multiple experiments seemingly have already shown
18:43 that it is possible. Perhaps the first murmurings of quantum time travel came in March 2019,
18:50 when details emerged of a multi-authored paper from an international team based in Russia,
18:56 the US, and Switzerland. According to a report from the Moscow Institute of Physics and Technology,
19:02 or MIPT, physicists were able to reverse time using a quantum computer. To set the scene,
19:10 the MIPT explains how an isolated electron in a vacuum of interstellar space, i.e. how the
19:18 tiniest bit of reality in the least chaotic conditions in the universe could theoretically
19:24 be smeared between the present and the past for a tiny fraction of a second. It suggested that
19:33 a random fluctuation in the Cosmic Microwave Background Radiation, or CMB, might achieve this,
19:42 although the chances of it happening are extremely, extremely low. As the MIPT puts it,
19:49 "Even if you spend entire lifetimes of the universe again, watching 10 billion plus electrons for
19:56 every second of that existence, then you'd only see an electron smear back in time once,
20:03 and only for much less than a second when it did so." Scientists are patient people,
20:10 but they're not that patient, so the team set about applying what they knew to a quantum
20:16 computing exercise, hoping to crunch those incredible odds all the way down so they
20:22 could eventually reverse time on demand. And to some extent, they succeeded. Using a relatively
20:30 simple two-qubit setup, they were able to set those qubits into life before effectively pausing
20:37 them and sending them back to where they came from, back in time, all the information within
20:44 effectively untouched, and order seemingly restored out of growing chaos. With the two-qubit
20:51 computer, the team was successful 85% of the time. When they added a third qubit, that rate
20:59 dropped to 50% of the time, and were they to have added more, the rate would likely have continued
21:05 to fall with every added complexity. But nevertheless, on some level, this could be
21:12 described as real, true, observable, and possible backwards time travel. Just over a year later,
21:21 in July 2020, news broke of a joint research project out of Los Alamos National Laboratory.
21:29 Here, in a study involving another quantum simulator, in a similar, although not identical
21:35 setup to the MIPT experiment, researchers were able to show that the fabled butterfly effect
21:42 didn't take hold at the quantum level. The butterfly effect is the theory that even small
21:48 changes in the past can massively alter the present, and the same for the present into the
21:54 future. But when the Los Alamos team ran qubits through their quantum processor, again as through
22:02 back into the past, but then altered them ever so slightly, it was found that very little effect was
22:10 still noticeable when those qubits were brought back to the present. They hadn't carried the
22:16 altered information through in any meaningful way. Could this, then, be a sign that quantum
22:23 time travel is not only possible, but potentially safe as well? Finally, in late 2022, reports were
22:31 that there had been two independent studies, published within days of each other, both
22:37 achieving a quantum time flip, specifically with photons, the subatomic particles of light.
22:44 This time, it wasn't a quantum computer at the heart of the experiment, but a specifically
22:50 structured crystal, although it's claimed that there could be major implications for quantum
22:56 computing in the future. In short, the studies passed split photons through the crystal, making
23:03 use of quantum superposition, and upon measuring them afterwards, when they'd recombined, they found
23:10 that while one split had continued along the expected arrow of time, the other had turned
23:18 against it. At its heart, this could be seen as in direct defiance of the second law of thermodynamics
23:25 and entropy, probably the trickiest barrier between us and time travel in general. Ordinarily,
23:32 entropy says that everything is always moving from order towards disorder or chaos. It never
23:39 goes the other way, which is essentially why we have the concept of time moving forwards in the
23:45 first place. But here, with photons shot through a crystal, it would appear that actually, to some
23:53 degree, physical matter and energy can move in the opposite direction, in an anti-direction.
24:01 Although the fact that the photons are split is important, ultimately, this isn't time travel
24:08 just yet, and certainly not in any practical sense. It's more a parting of ways at the quantum level,
24:15 and yet another subatomic mystery for science to add to its growing list. Utilize those, or similar,
24:23 crystals within quantum computers, though, and the already boundless states of a qubit
24:29 potentially increase even further. The possible processing power soars again. For now, with all
24:37 three of these studies, we can't truly claim that time travel has been discovered via quantum
24:44 computers. But could these projects yet prove to be the seeds for even greater ideas and breakthroughs?
24:52 Today, we're smearing qubits back into their own past, recording how changes do and don't register,
25:00 and sending split particles into a seemingly impossible realm. There's still a long way to go,
25:07 and a major scaling-up operation that needs to happen. But still, that's why quantum computers
25:15 might one day, perhaps, make time travel possible.
25:22 It's a popular theme in film and TV sci-fi, usually painted as some sort of psychedelic
25:29 world… but is that how it really works? What's actually going on at the quantum level?
25:37 To understand the general strangeness of quantum mechanics, we first need to think about light.
25:50 Scientists were long baffled by light, unable to decide whether it was made up of waves or
25:54 particles. Isaac Newton was one of the earliest to claim that light was made of particles,
25:59 but countless others sought to prove that light had wave-like properties, too… until Albert Einstein
26:04 finally laid the matter to rest in the early 1900s, showing that light was both a wave,
26:09 spreading in all directions, and a particle, moving in one. That light was measured in
26:13 tiny pockets of energy called quanta or, today, photons. But it only became stranger from there.
26:19 Despite Einstein himself reportedly remaining sceptical about the theory,
26:23 quantum mechanics - analysing subatomic particles - was born out of these new schools of thought.
26:28 Einstein's issue with quantum theory was that he believed the world should be objective,
26:32 and in some way predictable and observable. But when we zoom into the quantum realm,
26:37 it's full of crazy, strange phenomena that look as if they have no place in science at all.
26:42 Here, all of our preconceived notions of what's real and possible - the known laws of regular,
26:46 classical mechanics - fall apart. In quantum mechanics, everything exists in a cloud of
26:51 probabilities, operating as though within a constant "what if" hypothetical. Particles
26:56 spin in two directions at the same time, matter passes through solid barriers like a ghost,
27:01 two particles become entangled and their fates are then entwined… they could theoretically wind up
27:05 on opposite sides of the universe, but they'd still somehow communicate instantly. Even temperature
27:11 behaves in different ways, leaving cold spots where standard thermodynamics says there should
27:15 be heat. One thing is certain; you would have to be incredibly small to enter such a place.
27:21 Scientists distinguish something as "quantum" when it's at its very smallest part,
27:25 with distances in the quantum realm typically measuring less than 100 nanometres,
27:30 with a nanometre equaling one billionth of a metre. Beyond that, it's almost impossible to
27:35 predict what the quantum realm would specifically look like. At this size, all objects lose any
27:40 sense of shape. You'd exist amongst blurry, blobbish atoms and particles, drifting through
27:45 infinitely vast expanses of apparent emptiness. So, in some ways, it'd feel as though you'd
27:49 been abandoned in an exceptionally weird stretch of outer space. Crucially, the particles that do
27:55 cross your path would seem to flash in and out of existence; they'd solidify only when you
27:59 looked at them and exist like a shadow in the corner of your eye whenever you glanced away.
28:04 In this way, quantum physics feeds into philosophical debate, seeming to redefine
28:08 the relationship between matter and people. Schrodinger's Cat is a famous thought
28:12 experiment by Erwin Schrodinger about quantum theory. It posits that there's a cat in a sealed
28:17 box, with a vial of poison that's set to randomly release at any time, killing the cat when it does.
28:23 From our position outside the box, we can't know whether the poison has been released yet and so
28:28 don't know the cat's fate. But quantum mechanics says the cat is both alive and dead, much as a
28:33 quantum particle is real and isn't, and it's only when we look inside the box that the reality
28:38 will be confirmed. Another study proved something similar with light itself; the double-slit
28:43 experiment. Using a screen with two vertical slits cut into it and shining light onto a canvas behind,
28:49 scientists found an expected wave-like pattern with bright and dim strips. But, when they isolated
28:55 the particles so that just a single photon passed through the slits at any one time, impossibly it
29:00 still produced wave-like behaviour. But then, right when testers set up a detector to actually
29:05 see how this was happening, the screen changed again and the light started acting like a particle.
29:10 More broadly speaking, the universe acts in one way, but right when we observe it,
29:14 it somehow changes. So, what we see could seriously be considered an illusion. And
29:18 this would be happening all the time could we view the universe at quantum level.
29:22 If the quantum realm somehow leaked into our everyday life, it clearly wouldn't follow the
29:27 traditional rules of nature or even basic logic. Your very presence and perspective would constantly
29:32 influence the behaviour of everything you could comprehend. It'd be as though you had a piece of
29:37 pizza with every topping imaginable all at the same time, but right when you decide you want
29:41 pepperoni, it becomes pepperoni. Or, as though you'd forgotten where you parked your car.
29:46 The car would then exist as a cloud of probability, simultaneously being in every space that you could
29:51 think of, and only choosing where it actually was when you began looking. So, in the quantum realm,
29:56 everything would be constantly shifting, only settling into place when you actually observe it.
30:01 In fact, even your own body would effectively scatter across all of existence until you
30:05 actually looked down to view it - despite that being impossible in our own reality.
30:09 Say you yourself were a quantum particle, though. There's a high, even inevitable,
30:14 chance that you'd get yourself entangled with someone else by merely bumping into each other,
30:18 just as particles do. Actions then performed by that other particle person would affect your own
30:23 experience, and decisions would suddenly be split between the both of you. In effect, if you decided
30:28 to bike to work, your entangled partner would choose to drive. If you went to bed early,
30:32 they'd stay up all night. If you spanned clockwise, they'd spin counter-clockwise.
30:37 Were you to enter the quantum realm but retain knowledge of your past life as a full-sized
30:41 person, life would undoubtedly be tricky, if not impossible, to get used to. You could never be
30:46 certain about anything, but could also be certain about everything, safe in the knowledge that
30:51 nature responds to your own observations. Convince yourself you adopted a puppy, and you might just
30:56 find one pawing at your feet. Believe you can walk through a wall, and you will. Hey, you might even
31:01 be able to teleport! You, like all the particles around you, now exist in all possible places at
31:06 once. So, if you close your eyes and picture yourself on a desert island, you'd feasibly end
31:11 up there. It'd be a unique, colourful and endless chaos, crammed with apparently impossible phenomena,
31:17 to the point where you'd be asking yourself what's real, or if real even exists anymore.
31:22 So, what do you think? How do you envisage quantum science changing humankind and the future?
31:29 Let us know your ideas in the comments!
31:39 So,
31:51 for now, there are some major potential breakthroughs that are only just coming
32:00 into view on this particular horizon. The near future is set to be an extremely exciting time,
32:05 as it becomes clear just how far the theories and research will take us.
32:10 And that's why quantum science might be about to change everything.
