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]
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.
What should be the angle of regular mirror
Too lazy to go 8000 metres to try this

Hello author, I've recently been working on a mathematical physics chronicles content and I very much need to edit 5 seconds of footage using the footage from the video you created, I really, really need the 5 seconds of material. I'll be sure to credit the source of the footage and @ your channel when I'm done with my work. I very much recognize your work and thanks again. : ) (The above text was translated by me, using a translation program, so please forgive me if I use the wrong words)😀
Go ahead. Use it.
How can we know that light hit only the succeeding teeth , light may be hit the 100th teeth or any other
thnx
When does the light reach the mirror
how could the waves combine together again if they hit different parts of the mirror on the return ?
But your waive hits the mirror that doesn't exist in the either the way you have it shown so the angle take the same time at a different distance.. how they found time travel. Our physical aspect doesn't fit the spherical essence of reality.. what you have shown is in a 2d format.. what happens isn't in 2d more like a 3d.
This experiment prove that earth is still.
Exactly.
No?
I am wondering how he kept the mirror at a 8 km distance from toothed wheel 😂
watching this before board exam❤
Thank you this was so useful!
Excellent explanation! I 've finally understood the function of the toothed wheel. Brilliant vid! Thanks 😃
Great, which software you use to make these animations please. Watching from Pakistan. You are really best.
Hi! Do you know what software was used to create this animation demonstration? If possible, please let me know. Thank you very much!
@@kavya1108 I am also waiting for response. If you get to know, then please share with me too.
@@StudywithmeinPakistan Okay, thank you for your reply. If I know, I will let you know
@@kavya1108 Regards
What language is it? Scotish?
How possibly could you calibrate the speed of that wheel so accurately using only your eyes? Ha. You can't. Somebody has to run the stopwatch even if it is to calibrate the lasers it all falls apart with the weak link in the chain of time measurement - the human eye and thumb reflex. Compared to the speed of light! Ha ha ha ha ha your thumb don't know jack buddy human error can never be removed and c is unknowable and inestimable. It very well could be equal to infinity. You wouldn't ever know
Very good work. My question, as always, is how possibly can you know the speed of the wheel? You can never know the speed with such accuracy to approach the measurement of the speed of light. Just as you can never know the speed and position of any object in the universe simultaneously. God is very tricky and the speed of light is better understood as the passage of time, as in light gives time to the universe. Or maybe I'm just a fool trying to put God in a little box and write Him down on an index card
I thought I was good at math until this video
Can something travel through nothing? The physicists say that this only means physics instruments are not capable of measuring absolute motion, they can only measure relative motion.
Good assumptions .
To reject the aether because of this experiment is to reject the theory of Relativity. Using basic relativity math, it's easy to see why this experiment won't be able to detect an aether even if one exists. The 2 way speed of light is the same IN ALL DIRECTIONS for all inertial frames of reference, so even if you are moving relative to the aether, it is impossible to measure your velocity relative to it using 2 way light signals.
very accurate 💯👍
The fact there is no interférences, even the onces caused by Foucault earth rotation should show us that there is an ether but sticked to the earth's surface, according to me. Or on the reverse hyperfluid in wich the movements don't disturb the perfect galileen Light propagation bound to earth's surface.
VERY GOOOOOD JOOOB THANKS YOU, YOU SAVE MY LIFE!!!! I LOVE YOU :))))))
there is intrinsic error in this method. you cannot guarantee that each slot in the wheel is EXACTLY the same. Because PI is not exact it can never be accurate. each slot must be made to within wavelengths of accuracy that cannot be achieved.
light has not been measured in One Direction, and cannot Einstein even said we only know the reflective speed of light, not that of light in One Direction. So, hence the true speed of light is a theoretical, never measured
Wrong conclusion. The ether does exist and the earth is on a stationary plane.
Proof?
THANK YOU SIR GOD BLESS YOU
Dễ hiểu ạ Cảm ơn chủ nhà nhìu :">
Jist a question... How fast does the wheel actually have to spin?
If ether is our imagination, then what is Spacetime?
Ether doesn't exist. But space time does. It's in the fourth dimension so we can't see it, or know what it's made of.
@@placeholdernm lol. Can't see it, don't know what it is made of, has no well defined properties, but it's totally real. And it can't be an ether, even though we didn't define that thoroughly either.
@@destroya3303 You don't even know what the ether is made of, nor what properties it has. The only difference? We haven't seen any effects from ether, and from space time? A ton.
@@placeholdernm There is a huge problem with space time because it acts as just another ether but with less defined properties than ether models had. So it creates a huge contradiction since almost all relativists believe Einstein "did away with the ether". And at least with the ether they didn't say such strange concepts as "bend". There is some "interaction", or "wave propagation" or "movement" of whatever it was/is, but not something that defies reason like space (which is nothing) bending.
@@destroya3303 Sounds like you have no idea how General Relativity works. Put fabric over a trash can, now put a heavy metal ball over it. The bend you observe there? That's called gravity. The bend is imaginary, however we know it exists because we can observe the effects of it through a solar eclipse, like how it was first proven in May 29, 1919. Space is not an absolute nothingness. It is a vacuum, and there can never be a true vacuum. P.S. the aether hypothesis describes it as an absolute frame of reference, which is impossible.
this assumes that the time it takes for the light to get reflected is negligible, how do we know that the light doesn’t spend a lot of time in the mirror before being reflected?
What if earth is still?
Its not lol P.s. you wouldn't have been here to say this if Earth wasn't moving.
Has anyone measured light after two reflections? It's theoretically possible that light is instantaneous in one direction and twice (c) as long in the reverse.
I was thinking this would be a good science fair exhibit until he said the distance of the light had to be 8 km.
