How To Find The Value of Absolute Zero Temperature
Is there a limit to how cold things can get? Absolute zero is the temperature at which a thermodynamic system has the lowest energy. But how do we find its value?

It instead proved that light does not need a medium to travel. Background Music: Interstellar Sitar [freemusicarchive.org/music/Dana_Boule/We_All_Need_To_Calm_Down/Interstellar_Sitar_1847]
Great job bro
How can you place the mirrors in such a precise position with an accuracy of light wavelength? In early 20th century?
Why can't ether always be relatively at rest? As if it seems impossible that it's other properties are more than this
thank you for making this.
Taiwan fans are appreciated for this good video. Thanks.
What kind of light source was available at the time that could travel 8,000*2 meters ?
I would like the see this experiment on slow-mo why the light is not getting through the gaps😮
nice Viteo
epic
The same phenomenon occurs when we look at the rotating helicopter blades. This means that our brain works on the principle of current flow, so the brain sometimes has breaks to analyze the received image, so sometimes when the rotation of the blades is synchronized with our brain activity, we see that the blades stop turning. Sometimes we see that the blades are turning in the opposite direction. So measuring the speed of light with vision is absurd, because in this way we measure the reaction of our brain and not the speed of light, and since our brain works on electricity, the measurement showed the spread of currents in our brain.
But what if the ether is flowing up from the floor? Wouldn't you get the same result when you rotate the apparatus 90º?
Beautiful video! It highlights well the circularity inherent in our narrative; if we accept Einstein's 2nd postulate that the speed of light in a vacuum is invariant irrespective of the observer's POV or velocity, then the MM experiment is surely worthless! The assumption baked into MM is that an ether-like medium would 'resist' the 'flow' of light like aerodynamic drag or a river current pulling a boat sideways: the basic premise is absurd and the experiment proves or disproves nothing.
Bro please upload videos
Cool animation, but 1:13, that reflection was funny 😂
They seem to omit another obvious possibility: that the experiement was simply not sensitive enough to detect the effects of the aether.
It was calculated. And it was sensitive enough to capture the effects.
Best explanation
The conclusion at the end of the video is certainly not the only conclusion that can be drawn. Planet Earth, for example, can drag ether with it, just as it drags water and air.
That's bad science... -Ether could just move with the earth like air -The experiment wasn't even done in a vacuum/ether, it was done in air which is a medium like glass/water and has refractive incidence/variant speed of light. Good video though.
The light from the laser hit the mirror at an inclined angle does it not get refracted? If we increase the speed of the wheel will it be able to let light again pass ? .
Sounds like aether is more like pixels of reality
❤🥇
Null result - The conclusions -1. Earth wasn’t moving . OR, 2. There is no aether.
I do not know who you are... you worked great... 👌👌best video to know the "how to calculate the speed of light"
You changed my perspective about physics. I used to love physics in my high school and when I entered the university, I found it sooooo hard that I started hating it, but now, a spark of love has produced after watching the video. Thanksssss.
It's very exciting, but what if the speed of light in x direction in dofferent than the speed of light in y direction? See veritasium video to learn more
In just 4 min u explained so nicely. It was really better than 20 mins videos. Thanks a lot❤
Another possibility is that the Earth is not moving.
What’s cool is that? You do see an interference pattern shift and variation if you turn the experiment vertically.
God gave humans curiosity We've delayed our extinction with this one characteristic. But our other traits have ended life for other inhabitants.
Lies
Anyone from Bangladesh?
#Etherpanelsdialoguecorrection 👉 👈
OMG so deep!!! Thanks for the explanations mate!
Many problems with this video, first of all there are No astronauts, because there is no space. A so called vacuum of space could not exist next to an atmosphere of pressure! The ether is real, it is the substance found after the top of the atmosphere, it is the substance that rockets can not trail through, that is why you see rockets go up and then arch and fall down to earth again. The conclusion in reality is that the earth is actually stationary like the Bible says it is and the sun, moon and stars revolve clockwise around a flat circular earth. There are no planets, only stars, if you look at the so called planets through a p1000 Nikon you will see they are stars
That experiment is pure genius and elegant!
Keep it up ❤ excellent content very well explained
Good video terrible speaker.
They say light is too fast and how can you rotate the wheel that fast
The sheer arrogance of Michelson and Morley in ignoring the obvious fact that gravity is ether flow totally bewilders me to this day.
Assuming aether flows, then the direction of its flow should impact the trajectory of light. The Michelson - Morley experiment would have shown that light's path and speed would be affected accordingly. If aether flows in a certain direction, then it would affect the direction of light and its speed would slow if it moved against the flow of aether. But this experiment, and those conducted in the following 100+ years, showed neither of these things. Don't know why you brought up gravity because the Michelson - Morley experiment was not about this. But if aether does flow, then it must be downwards, because that's how objects fall...but that's basically the same thing as gravity. People used to think this a long time ago. Einstein took the idea of Aether and gave it more defined properties and called it spacetime.
@@johnkyle2205 The ether holds matter together. Now, the instrumentation that they were using was ironically being held together by ether and the ether was holding the experimenters down onto terra firma. The ether flows down and they were measuring across the wind flow at 90 degrees to the flow direction. Also, consider that the ether distorts objects like clocks when you move them. If you try to measure the speed of light with 2 synchronised clocks the one which is moved away will slow down due to the etheric pressure.
@@stephen7774I have two questions. How does ether hold matter together? If it exerts a downwards force it therefore flows in one direction only, thereby pushing objects away from it toward the ground. This means it exerts a mono-directional repulsive force and it is counterintuitive to think this kind of force makes matter attract matter. If Michelson and Morley measured across the wind flow perpendicularly, then they would have detected interference patterns in the light consistent with the flow of the ether wind and its direction. But they got nothing. So they rotated the apparatus. No difference. Still nothing. Kept moving it. They even put the flow of light in the same direction as the ether wind. But there was nothing, and they even had it in mercury to prevent it being affected by the Earth's rotation. Why does the ether flow not impact the flow of light like most scientists of the time thought? That's my other question. Actually, I lied, I have three questions. What do you mean by 'pressure' when you say etheric pressure? Is that the downwards force? How does it relate to, and affect time? Crap, I think that was more than three...
@@johnkyle2205 The universe is like an inflated tyre. Ether is created at the galactic centre axis where matter is destroyed and ether is created. The universe has multiple ether fractals -atoms, solar system and galaxy. Each fractal has a different rotation rate. Thus, there can be multiple directions of ether at the one location due to multiple dimensional overlaps. The universe is like a TV screen. Now, zoom in to one pixel in that screen and you find another smaller TV screen within. Zoom on in again to one pixel and find yet another TV screen. The downwards and inwards forces are extreme because they can create and destroy matter. See Martin Grunenick - extended Michelson - Morley Experiment. Turn the interferometer on its side. Now you are measuring ether! Note - Star light bends around sun and galaxies. Why? The ether pushes it of course!
@@johnkyle2205 Refer to Martin Grunenick - Extended Michelson - Morley experiments. The ether is multidimensional. The universe is divided into fractal dimensions. Just because gravity pushes down doesn't mean that micro fractals can't push in other directions. Matter is a hole in space which ether falls into. Note - E=MC squared light=s ether or x 2 particles of opposite spinning ether collide at the galactic centre plane and create energy, light and matter. This collision leaves a hole in space which must be filled and some particles get caught in rotation which becomes what me call matter.
Thanks for the explanation!
3:23 “vertical faces no resistance” but will be slowed down. as it now has to cover more distance. making the 2 beams always synchronized. making this experiment invalid. as it can never detect any stream of any medium. including sound and water surface waves. 😊
Super clear. Which is super.
1. How they define the distance exactly? 2. Why the frequency of the tooth and gaps only matters? 2*720?
The conclusions are very narrow-minded because it doesn't take into account that some of its assumptions are false. For example one of the conclusions could be that the earth is not moving, or at least moving at a negligible speed. Or another conclusion would be that the ether doesn't move.
The answer is very simple. The nature of light and magnetism is instantaneous, always! All I have to do is watch the sunrise or turn on a lamp. The lamp could be 500 KM's away and the light would still be there instantly. The luminous ether is dynamic and does not rest and no translational movement of the earth can be measured with an interferometer, but society does not want to accept this answer, instead it would rather cling to a diabolical lie!
What nonsense!! Michelson Morley's experience does not prove at all that there is no so-called ether and that the speed of light is the same from every direction! No one has ever measured the one-way speed of light. Of course, the reflected light reached the observer at the same time, but this is due to the contraction of the dimension in the direction of motion! Nobody knows what the actual distance measured in the structure of space is from the M1 and M2 mirrors to Ms. The forces in the atom are transferred by photons and to keep the electron at the same time distance from the nucleus, the atom becomes elliptical, smaller in size in the direction of motion.
Genius experiment.
Beautiful explanation, and immaculate derivation. I now fully understand this experiment, as a former math minor.
Nice video but to be clear, there WAS an interference pattern.....the notion that they had the precision back then to position the mirrors exactly equidistant is wrong......what they DID observe was that the pattern didn't change when the orientation was adjusted......same conclusion but i think that detail is important.
The distance travelled is completely wrong, since you are using your eyes to observe, if a camera is placed on a tooth of the saw to observe then the distance measured will be correct. Since you used your eye as a screen, you need to add that to the distance covered, even the diameter of your eye ball should be added along with the distance between the saw and the semi-transparent glass.
