It is the fisrt time that I see Jim Al-Khalili, I’ve been following his Life Scientific podcast on bbc radio4 since 2018 my IELTS preparation time. I wanna thank mr. Jim Al-Khalili and his podcast guests for that amazing show.
Thank god for the BBC making docs like this, if it wasn't for BBC Horizon docs like this one or Professor Brian Cox and Sir David Attenborough there would be nothing intelligent left on TV
Thank you all British subjects for paying your telly taxes so us in the Commonwealth colonies can still soak up the culture of our mother country. From Canada.
I find it repulsive that you praise the work of Cox and Attenborough, you credit the BBC for availing their work, and you thank an invisible mythical being for making it all possible. Perhaps one day the BBC will air a program to demonstrate where you went wrong.
Seen all these when they were on TV. Jim is superb at these documentaries. This is the kind of content I approve of on RUclips. Leave the short form - non educational content to other apps for those with no attention spans.
@@MegaLmae I think you'll find a lot do agree with my statement, just ask anybody with a brain and wasn't born in the 2000's. You cared enough to comment, heyyyyy 👋🏻
It seems to me (judging by the graphic depiction) that when we finally understand why these strange phenomena occur the wavelike illustration used might also describe and/or lead to scientists understanding force fields, magnetism for example. Awkward, I know, but the poorly defined path of the quantum looks like a field, not a lot of individual particles.
You by far have the absolute best videos, and honestly my knowledge is basic when it comes to physics, but you make it clear and easy to understand everything.
So, the "fabric" of space itself, in between the galaxies, is what is expanding. And what is this fabric made of? Nothing. "The universe itself, in it's entirety, is getting bigger" -So, its endlessness is getting even more endlessy. You've got to love these "explanations".
The fabric of space is not "nothing" - this is explained in other Khalili videos. Moreover, these are speculations not explanations. Yes the Universe is expanding and we don't really know how or why but we will invent a place holder - Dark Energy - so we can talk about it. Maybe rewatch the video.
@@rpprevost What??? Go look it up - I'm not spoon feeding you a complex idea like that on a YT forum. Jeezez you people are f'n' LAZY. If you cared to learn you would make your own effort and not expect other people to do your work for you. Plus your question is just so basic and banal that I have to think you are baiting me for some reason. You REALLY do not understand the difference between ENERGY and MATTER?? If not, no one can help you.
Dude! It’s so fun and interesting to see the wheels turning in such detail. Now I have to get the guitar out and give it a go. I mean that as high praise- imitation=highest flattery. I hope you feel inclined to post more soon.
Jim Al-Khalili is taking us on a mind-bending journey through the mysteries of life, the universe, and everything! Who else is ready to expand their mind with Part 1?
@@walshamite yes, a very personable and likeable chap. I've seen other RUclips vids on the same topics as Jim's but they're using quite long-winded and hard to follow. I watch Jim with my sons and he's able to hold their attention (which is tough these days what with children's minds being over-stimulated by tablets/phones/electronics)
Entanglement seems perhaps easy to understand. If a particle is also a wave and you grab a positive or negative part of the wave to manifest it from wave to particle, what’s left of the wave is the opposite side of the cycle. A wave starts at zero the swings off from there in one direction, but to complete the wave, it needs to return to zero then swing the opposite way as the first half. You grab the top or trough of a single wave, what’s left? The other half.
Has anyone done the two skirt experiment over time. What I mean is fire one electron, wait a day, fire another electron, wait another day, and repeat to see if the pattern repeats or if it’s less evident? What if the wave of the particle is in the ether instead of part of the particle and that’s what causes the interference. Maybe I’m nuts but I can’t seems to find anyone who’s tried it and published online. Not the best online discoverer. Let me know if anyone has an answer.
Wow first comment I've seen where someone actually asks a useful question. How things are actually discovered or truths are found out. theoretically particles are entangled for eternity like mating swans. Still should be checked. Some scientists say the more they learn the more they believe in a god. Why I'm agnostic. I'm still waiting for proof but not atheist.
This is why Einstein had a hard time accepting any of this, even called it " Spooky action ". It is counter intuitive, electrons behave wavelike until they're observed that they turn back into particles, no matter when it happens. First comment I see about the actual content of the video, and not about its production .👍
This guy has made some of the best documentaries ever. I want to find the series about the evolution of the motor engine, phones, planes and something else. 4 part series used to be on netflix. The engine and aeroplane ones were awesome!
at 19:35 Jim is at Branksome Chine or Westcliff which is a beach on Poole Bay , Bournemouth SW England & one thing within this presentation which I knew without it being explained 😁
My family tree Arabia, Iraq, then migrated to Samarkand Bokhara Uzbekistan through Russian/Slavic areas, India, Pakistan, and birthplace England. Interesting regarding Iraq where Jim Al Khalili links. The qu'ran (Koran) is read and taught in Arabic. The word Alien (ferung) or outsider has many definitions .
Simplicity development, to become information is existence. I will create an imaginary parallel line, I now find it’s equidistant point, here I deform the line into an angular shape. Thus acquired transition of energy for this activation, this will give the line separate components as vectors= polarity or indicated Pole, One N. Two S .+ Direction. = “ information” -magnetic field of plasma?
So if the universe is expanding and therefore the light of galaxies is moving further away from earth. Aren't we supposed to move together in sequence? Is earth standing still in one place? That everything (stars and galaxies) else is moving away from us?🤔
The two slit experiment always gets me. Electrons travel in a straight line. So unless your aim sucks, they will hit where they are aimed. How can you get a wave pattern firing at the same target? When you see a wave pattern with water, it's because you have millions of molecules of water interfering with each other. With the two slit experiment, they are firing single electrons. There's nothing for the electron to interfere with, including other electrons. It just doesn't make sense.
@@cathyzeiler9967 My objection doesn't involve quantum mechanics, as far as i can tell. I'm open to an explanation as to why my objection is irrelevant.
All matter has wave particle duality, so even an electron travels like a single wave through both slits, creating the interference pattern from the then two waves coming out of the slits
@@smokert5555 No, it can’t be explained in terms a person can understand. And yet it happens - even individual electrons (or photons, or neutrons…) interfere with themselves. But don’t think of electrons as little billiard balls, they’re just little packets of probability that can exist anywhere theoretically but “tend” to be on a main line. But they exist everywhere at once, just with rapidly diminishing probability as you move away from that line. It’s clear mathematically, but we can’t visualize it because we didn’t evolve brains that needed to, if that makes sense.
If its the fabric of space thats expanding and not the galaxy's flying away from each other how do you explain the prediction of andromeda galaxy and milky way galaxy colliding in the future???
Jim, as God says everything is being / is written in a book. There is your 2d storage of info. That is the holographic theory you mention. Food for thought.
Wait, hold the phone. I love Jim’s stuff, but i believe he is completely wrong on something here. The ‘fuzzy’ part of the shadow around his hand is not because of the wave of light bending around his hand, it is because of mie scattering causing the light from the sun to bend when it hits large particles in oir atmosphere, causing us to see the sun, not as a very small disk, but as a much larger source of light. Basically the sun photons get deflected on their way almost like someone was holding a fuzzy magnifying lens between us and the sun. The effect is what would otherise be a shadow from a small light source(point light) which would have a very hard shadow edge, instead the sun to everyone on the surface of earth becomes a much larger area light(area light source) and thus like all wide light sources it had a penumbra in addition the umbra part of it’s shadow, and hence the hand he held up has a larger fuzzy region had the sun not had it’s light scattered by Mei scattering. Note Rayleigh scatter is responsible for the blue light and generally shorter wavelengths of sun light hitting the atmosphere being scattered to produce the blue sky we see. This in someway also messes with our shadow as it causes blue light to fill in oir shadows so they are not completely black as say they would be out in space when far away from other bouncing light from say the earth which can also cause the shadows from the sun to be partially lifted, like the shadows on the side of the international spacestation facing the earth, or sometimes the moon’s bounce light can also lift the shadows as well on the ISS when they are aligned correctly. But anyway, the point the shadow of his hand on the bricks was fuzzy not because of light bending around his hand. That does happen but it is very small, compared to the effect that the Mei scattering is having on the sun as an otherwise nearly parallel source of light rays(photons). If he held up his hand in front of a very bright tiny light source in a completely black room, it would not have a fuzzy shadow like it does in a sunny day…. Anyone else pick that up as being Jim mistaken for once?
I agree. I like Jim's videos, but it's a shame that he describes the fuzziness of the shadow as being caused by light smearing out rather than the source having a wide area. It is made worse by it being presented as "common sense". Light does to some degree smear out, but would not be detectable on the wall if the source was infinitely narrow. I still really enjoy his videos, he presents very well.
This mischaracterization of a fuzzy hand shadow (more easily explained by the contrasting the shadows from a pinhole lens and a larger lens) is a regrettable lapse, but does not enlarge into a fallacious examination of the theories that follow--which may or may not be relevant, but certainly provide grist interesting contemplation.
Good Nice Video. So, on what basis the Universe still exist and does not go extinct? is it only because of Constsnts? speed of light, gravity constant , Plank's constant?
Every event has 4 coordinates: its location in the 3 space dimensions, and a time coordinate, too: this happened here, at that time. If it's spacetime - emphasis here on time - flowing into a black hole, the event horizon is not (just) a 2D spherical surface in 3D space, but also in time: it's a set of events in spacetime - the last events from which a signal could reach an external observer. So, in the holographic solution to the information paradox, is what we're really talking about not a "flat" "picture" of what "fell in", but a "slice" of its trajectory through spacetime? What happens to this holographic info as the event horizon shrinks as the black hole loses mass-energy, and therefore size, through Hawking Radiation? Keen to hear what people think...
Everything we call real is made of things that cannot be regarded as real. If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet. 🍀 Niels Bohr
"If you wind the clock back far enough, there must have been a point of Creation. " That I believe says it all. No further need to look for explanations. Creation by definition indicates that a Creator has been at work.
@dukeon 'Who created the Creator? I just rephrased your question to highlight the logical fallacy within the question. Anything that is included in the category of creation can be asked this question, but the Creator, by definition, does not fall into the category of created things. When you have exhausted the chain of causal links, you arrive at the Creator and can not proceed any further.
My contribution to physics. I just thought of an experiment to prove this model. (See above) (Sounds_4_People X) Since the hydrogen atom represents one quanta of gravity, make a spherical container of a very precise amount of hydrogen, using a defined amount of elements in the sphere. Outside the ISS. First measure the gravity of the empty sphere. Second, fill it with liquid hydrogen and log the added amount of gravity. Simple. Doable. Replicable.
The events that we describe as the big bang brought about the universe we know today. Yet we don't know what or how brought the event on the we describe as the big bang 😢❤😅😊
Information is only lost if the black hole is the only thing with the information. The information still exists if the info is shared. But if the info is only held by the black hole did it really exist in the first place. Once again the proof that connection is important.
Why do physicists always fail to see that Space and Time only intersect in the context of relative motion??? Seems so obvious to me. Spacetime, the dimension of (relative) motion. Space literally means the emptiness between. Space is actually a homonym - a word with more than one core meaning. You need to differentiate - you don't. The XYZ-axis is a mathematic model, a three vector dimension for referencing (calibrating and indexing) relative spatial position. You can't curve a mathematical model. Or Space is a vague collective noun as in 'outer space' - like 'sky' is a vague, non-specific collective term - encompassing 'stuff' (matter) and the emptiness between 'stuff'. You can't curve collective nouns. And Time is also a both a dimension (we calibrate change rate and reference change-events using Time), and a vague collective noun - the only evidence of 'time passing' is change (look around you - quintillions of change-events) including the change of spatial position i.e. motion. So merge Space, the dimension of spatial position, with Time, the dimension of change, and you get Spacetime, the dimension of changing spatial position, i.e. the dimension of (relative) motion.
Maybe the visible matter that falls into a black hole, gets 'smashed up', only to sometime later, piece back together to its original form and exit the rear/end of the black hole into another universe?
Mind you not that long ago minds of the authorities of the time thought the Earth as the centre of all creation. This is somewhat true consideration of that which is known as the observable universe 😮
Kazakhstan. The result is a “theory of everything” in a simple device. Einstein dreamed of measuring the speed of a train, a car - using the Michelson experiment of 1881/2024, and only then the experiment would be 100% completed. This can be done using a fiber optic HYBRID gyroscope. Based on a 100% completed Michelson experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum.
That characteristc of partcules communicate instantly independet of distance, could be the solution to communicate with satélites very far in other planets. Must be investigated like radio waves and transistor were investigated years ago.
I see where you're going with this, I've noticed that the energy of a wave is just passing through the water, surfing only happens once you catch the wave of energy, and when it crashes against the shore, you can feel it escaping the water.
Spin a coin in front of a mirror then move the spinning coin awat from the nirror, this is your mysterious quantum entanglement vusuakised. its the same coin that appears to spin the opposte way instantly. The double slit is not hard to explain either
Einstein was wrong about time being the 4th dimension. 1st time can only be measured in one direction. I would argue that the 4th dimension is density( expansion/contraction) as the universe expands it can also contract but time is always this then that.
Why don't you guys go up in outer space and video record in x-ray, UV, and any other part of the spectrum we can't see with out naked eyes and show it to the public? The people deserve the right to know just how bizarre our universe really is.
Dear Mr Al Khalili, your background pictures when explaining DO NOT HELP to understand the subject matter but distract. Also, you walking away simply after making a dramatic statement may look impressive, but a big error! That is exactly when you should stay put and explain in various ways!! Note that this 80 year old engineer is a LONG TIME ADMIRER and listener of your presentations. Cheers
Maybe I am to simple. But the image of the duck is simply light standing still with that image lost in amongst all the other images of matter falling into the black hole The duck can only be compressed to a point not broken into pieces all that matter after being compressed to it's maximum density to my mind obviously returns to the energy that created the particles that made the atoms with that energy being radiated from the black hole And obviously that energy radiated is then available for the recreation of the subatomic particles that create the atoms that create matter But of course this statement will be lost to the internet
God gave us FAITH but scientific knowledge as well 😢😢😢if we have to deal with so much stupid people, having no FAITH no belief no trust either scientific knowledge well, it means we need good inspiring skilled teachers to open their minds but their hearts as well 🎉❤🎉
Really? God gave us scientific knowledge? One wonders why his supposedly infallible official biographers tell us he created a flat Earth 6,000 years ago pre-salted with dinosaur fossils. Also, he suffered an infinite succession of mass murderers to live long and bloody lives in his paradoxical paradise. I think we're entitled to question his competence as a god..
I don't believe the holographic thing. When you watch a video on a 2D screen, it looks 3D, but when an object goes behind another its information is stored back on a chip only. Not stored on the screen. Only storage on the screen is its amount of pixels. The chip has more storage than the screen. Back to where does it go?
Why would we be holograms in the holographic theory. All it says is that we are two dimensional at our core and I think we will eventually get to one dimension and discover that the entire universe is just a particle. We are all one.
Science cannot answer these types of questions. It gives us the what, but never the why. When a scientist cannot explain what gravity is, what energy is and be able to measure the actual speed of light, then it still cannot explain why we are here.

So, in the holographic solution to the information paradox, is what we're really talking about not a "flat" "picture" of what "fell in", but a "slice" of its trajectory through spacetime? What happens to this holographic info as the event horizon shrinks as the black hole loses mass-energy, and therefore size, through Hawking Radiation? Keen to hear what people think...

Everything we call real is made of things that cannot be regarded as real. If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.

I wish he had told us to put some UV glasses on too, that light almost blinded me
"If you wind the clock back far enough, there must have been a point of Creation. "
That I believe says it all. No further need to look for explanations. Creation by definition indicates that a Creator has been at work.
How was the creator created? You haven’t solved the problem you’ve just inserted a middleman.
@dukeon 'Who created the Creator? I just rephrased your question to highlight the logical fallacy within the question.
Anything that is included in the category of creation can be asked this question, but the Creator, by definition, does not fall into the category of created things.
When you have exhausted the chain of causal links, you arrive at the Creator and can not proceed any further.

My contribution to physics.
I just thought of an experiment to prove this model. (See above) (Sounds_4_People X)
Since the hydrogen atom represents one quanta of gravity, make a spherical container of a very precise amount of hydrogen, using a defined amount of elements in the sphere.
Outside the ISS.
First measure the gravity of the empty sphere.
Second, fill it with liquid hydrogen and log the added amount of gravity.
Simple. Doable. Replicable.
So Two Particles were entangled in the Boundary of Universe from beginning, we measure the Hologram of them, space disappears Wow!
The events that we describe as the big bang brought about the universe we know today. Yet we don't know what or how brought the event on the we describe as the big bang 😢❤😅😊
this is just excellent! many thanks!
It seems like we're not really certain about time being the 4th dimension.
30:00 “Shut up and calculate “ 😂
Hey aziz. Please do a vid where u are showing all your musckes and holding a metal ball.
Information is only lost if the black hole is the only thing with the information. The information still exists if the info is shared. But if the info is only held by the black hole did it really exist in the first place.
Once again the proof that connection is important.
Its great stuff, really understanding it though mmm it's quantum theoretical
I'm trying to understand!
Why do physicists always fail to see that Space and Time only intersect in the context of relative motion??? Seems so obvious to me. Spacetime, the dimension of (relative) motion.
Space literally means the emptiness between. Space is actually a homonym - a word with more than one core meaning. You need to differentiate - you don't. The XYZ-axis is a mathematic model, a three vector dimension for referencing (calibrating and indexing) relative spatial position. You can't curve a mathematical model.
Or Space is a vague collective noun as in 'outer space' - like 'sky' is a vague, non-specific collective term - encompassing 'stuff' (matter) and the emptiness between 'stuff'. You can't curve collective nouns.
And Time is also a both a dimension (we calibrate change rate and reference change-events using Time), and a vague collective noun - the only evidence of 'time passing' is change (look around you - quintillions of change-events) including the change of spatial position i.e. motion.
So merge Space, the dimension of spatial position, with Time, the dimension of change, and you get Spacetime, the dimension of changing spatial position, i.e. the dimension of (relative) motion.
Do you,Jim, study Crop Circles ? Dimensions indeed...
Maybe the visible matter that falls into a black hole, gets 'smashed up', only to sometime later, piece back together to its original form and exit the rear/end of the black hole into another universe?
Mind you not that long ago minds of the authorities of the time thought the Earth as the centre of all creation. This is somewhat true consideration of that which is known as the observable universe 😮

The result is a “theory of everything” in a simple device.
Einstein dreamed of measuring the speed of a train, a car - using the Michelson experiment of 1881/2024, and only then the experiment would be 100% completed. This can be done using a fiber optic HYBRID gyroscope. Based on a 100% completed Michelson experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum.
That characteristc of partcules communicate instantly independet of distance, could be the solution to communicate with satélites very far in other planets. Must be investigated like radio waves and transistor were investigated years ago.
Its not science that leads to my frustration, its economics
This shit is my jam!!! Hell yeaaa go physics.
I thought light particles are called photons!
And quanta was word coined by Plank for energy.
Am I wrong?
Light is a form of energy. It behaves as a quantum particle (photon) and as a wave, depending on how you measure it.
isn't water also "wave" in ocean and "particle" like droplets dropping off Tap water?
I see where you're going with this, I've noticed that the energy of a wave is just passing through the water, surfing only happens once you catch the wave of energy, and when it crashes against the shore, you can feel it escaping the water.
Spin a coin in front of a mirror then move the spinning coin awat from the nirror, this is your mysterious quantum entanglement vusuakised. its the same coin that appears to spin the opposte way instantly. The double slit is not hard to explain either
Here's looking at Euclid.
Einstein was wrong about time being the 4th dimension. 1st time can only be measured in one direction.
I would argue that the 4th dimension is density( expansion/contraction) as the universe expands it can also contract but time is always this then that.
Time is easily seen as a dimension. Try to meet someone in three dimensional space without it.
I can't understand why old video back to back uploaded
Why don't you guys go up in outer space and video record in x-ray, UV, and any other part of the spectrum we can't see with out naked eyes and show it to the public? The people deserve the right to know just how bizarre our universe really is.
When did this originally get aired? 2007?
It aired in 2022
Never trust anyone who wrote a guide to life, the universe, and everything.
Dear Mr Al Khalili, your background pictures when explaining DO NOT HELP to understand the subject matter but distract.
Also, you walking away simply after making a dramatic statement may look impressive, but a big error!
That is exactly when you should stay put and explain in various ways!!
Note that this 80 year old engineer is a LONG TIME ADMIRER and listener of your presentations.
Cheers
Love the program and the narrator. Ads every 5 minutes ruined the experience.
It seems most likely that our universe itself is alive.

Like we're recorded on a CD or a DVD and someone is playing us for their entertainment
I always knew that I was being played…..
We don't know, there saved you some local time 👍
Before the big bang was quantum mechanics and the primordial make-up of a dense prime-niverse. 😅
Maybe I am to simple. But the image of the duck is simply light standing still with that image lost in amongst all the other images of matter falling into the black hole
The duck can only be compressed to a point not broken into pieces all that matter after being compressed to it's maximum density to my mind obviously returns to the energy that created the particles that made the atoms with that energy being radiated from the black hole
And obviously that energy radiated is then available for the recreation of the subatomic particles that create the atoms that create matter
But of course this statement will be lost to the internet

God gave us FAITH but scientific knowledge as well 😢😢😢if we have to deal with so much stupid people, having no FAITH no belief no trust either scientific knowledge well, it means we need good inspiring skilled teachers to open their minds but their hearts as well 🎉❤🎉
An open mind is not one that believes in supernatural agency. That requires denial of reality and therefore demonstrates a closed mind.
Really? God gave us scientific knowledge? One wonders why his supposedly infallible official biographers tell us he created a flat Earth 6,000 years ago pre-salted with dinosaur fossils. Also, he suffered an infinite succession of mass murderers to live long and bloody lives in his paradoxical paradise. I think we're entitled to question his competence as a god..
I don't believe the holographic thing. When you watch a video on a 2D screen, it looks 3D, but when an object goes behind another its information is stored back on a chip only. Not stored on the screen. Only storage on the screen is its amount of pixels. The chip has more storage than the screen. Back to where does it go?
I don't think you've grasped what they meant by the holographic thing. Screens and chips have nothing to do with it
@johnlonkert7187 no I don't. And neither do they
@johnlonkert7187 so do you understand the math? Because they are the ones that made the comparison. So let them know that they can't do that.
I thought that eney matter going down a black hole comes out the other End. You know what I mean it doesn't stay in the black hole
This is my new sleeping show..
I listen as I drift to sleep to nothingness..
If a black hole evaporates away to nothing, then the is no longer an event horizon, no?
Why would we be holograms in the holographic theory. All it says is that we are two dimensional at our core and I think we will eventually get to one dimension and discover that the entire universe is just a particle. We are all one.
Why do I feel like I’m some kind of mistake
Me too. Still trying to find my place/meaning in this world. I am 64 years. Oops!
Science cannot answer these types of questions. It gives us the what, but never the why. When a scientist cannot explain what gravity is, what energy is and be able to measure the actual speed of light, then it still cannot explain why we are here.
