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.

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.

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.

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".

@kaoskronostyche9939

17 күн бұрын

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.

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.

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?

11:00 The "big bang" is a supposition as great as anything else might be. If the space is expanding it does not necessarely mean that at some point it was only a dot, it could also be like a storm or throwing a rock. If space is expanding at some observable point, it does mean that it is expanding at that point. Even when you physicists say it is like baloon, did you ever play with circus baloons and saw how they can be twisted and shaped even to look like an animal?

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.

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...

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.

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?

Hey aziz. Please do a vid where u are showing all your musckes and holding a metal ball.

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?

@markghinn6072

Ай бұрын

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.

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.

Its not science that leads to my frustration, its economics

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?

@dukeon

Ай бұрын

Light is a form of energy. It behaves as a quantum particle (photon) and as a wave, depending on how you measure it.

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.

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

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.

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.
