This guy's videos are the best.

Jim is my favourite science communicator since Carl Sagan.

Profoundly beautifull! Thank you all for this amazing documentary! May the force be with you 🙏

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.

Very wonderful lecture like all the others;especially well understood when accompanied by classical music.

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.

This is A Stellar Episode 😎👍

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".

I can't get enough of these kind of programs, even though they sometimes leave my head spinning afterwards.

Seen all these when they were on TV. Jim is superb at these documentaries. This is the kind of content I approve of on UKposts. Leave the short form - non educational content to other apps for those with no attention spans.

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.

Top man Jim!

Jim seems the kind of guy you would like to have a beer with and discuss things. Of course, if it was me, it would be very one-sided.

Love Jim!

This is good stuff. Helps me to stand in awe of creation and its enigmas. And how were endowed with the gift of understanding. Amazing and awesome.

I love this great man ❤

Always makes the subject interesting, good on yer JA-K👌🥇👍

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.

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?

Jim is excellent amazing video

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...

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.

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 😁

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?

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?

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.

"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.

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?

Do you,Jim, study Crop Circles ? Dimensions indeed...

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.

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.

I can't understand why old video back to back uploaded

Not many people born in Iraq are named Jim 😊

When did this originally get aired? 2007?

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.

I thought light particles are called photons! And quanta was word coined by Plank for energy. Am I wrong?

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?

isn't water also "wave" in ocean and "particle" like droplets dropping off Tap water?

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.

This is my new sleeping show.. I listen as I drift to sleep to nothingness..

Like we're recorded on a CD or a DVD and someone is playing us for their entertainment

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 🎉❤🎉

I've seen light... I just cannot prove it to you.

This shit is my jam!!! Hell yeaaa go physics.

If a black hole evaporates away to nothing, then the is no longer an event horizon, no?

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

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

However since the universe isn't locally real the black holes are not locally real either

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?

Not sure what you mean Who are you calling stupid ?

Almighty Allah increase your intelligence about Scientific Real world. Al PAZA

Love the program and the narrator. Ads every 5 minutes ruined the experience.

Makes me certain that casinos shut up and calculate how to make money with entanglement

My point is not the meanings. Plank's quantum is calculated as h to an exact no. I have not come across anyone applying it to a photon, WHICH I THOUGHT was coined be Einstein. Plank used the smallest quantity to explain the anamaly of, I think, color of light vs temperature. I just was confusedthe word quanta used instead of Photon by Mr J Al K

Quantum Field Theory provides everything that is needed to explain how the Universe came into being. There was no big bang. The enormous scale of structures in the Universe, makes that quite apparent.

Everything and nothing all over again?! I love Jim Al Khalili’s documentaries but lately it’s been deja vu over and over again... is he even still alive? Or is this AI??

TO GIVING SUCH TYPE INFO MEN SHOULD BE LIKE ADAM STEPHEN HAWKING. SPECIALLY TO GIVE END AND LIFE START MEN SHOULD BE BUDDHA OR CELIBATE MAN OTHERWISE KNOWLEDGE ULTIMATELY WRONG BY NATURE ORDINARY MEN CANNOT GIVE THESE I GOT ALL FROM BUDDAS STSTEMENT

So long and thanks for all the fish. I'll see you all at the restaurant at the end of the universe.

My wife is pretty sure all other women in this world are not holograms, quite contrary!

Yes… Theories… Never forget that God created ALL of it.

What if black hole singularities are the singularities that start new bubble universes and it's just the bridge between the two that evaporates and the information is safe it's it's new bubble of space time, in the new born universe?

Kinda pretentious.

SpaceRip .,. [ CHECK MARK ] .,. (*Got to love it!*) Prof. Jim Al-Khalili .,.,. ! Thank you!

who cares what is your name, hellou, we are here for physics, not your vanity (at least the smarter among us are)

Does channel has really gone downhill. This is what Kyle Hill meant when he talks about UKposts becoming oversaturated with crap

I don't get my scientific information from religious fanatics.

if protons act like waves that means that space has some properties which is like a ocean, kind of space with anti water or anti ocean

Jim to much too Smart to be Anything But an Atheist

hir we go again

is the camera man japanese
