Michelson-Morley-Experiment

[TaylerKnox]

But like uhmm what's about virtual particles - dark matter - dark energy - I mean even in a vacuum there's no vacuum - vacuum is a concept - thus field effects and mass even where we believe nothing exists - maybe the ether is the membrane? Think about that? We call it M theory.

good video for visual purposes. but in actual fact, the compensator plate is missing, is should be placed behind the beam splitter (but in front of the mirror) and also parallel to the beam splitter.

(part 3)

When they got the result, they found the inteference pattern was identical. This contradicted the physicists hypothesis. The reason for why the rays interference pattern was the same because the speed of light is constant is all frames of reference thus not needing the aether model to explain lights propagation. final remark, the aim of the MM exp was not to prove that the ether model existed. Hope this helps, and ask me questions if your unsure.

(part 2)

The vert and horiz rays then meet at the detector recording a distinct interference pattern. They then re-did the experiment at a different angle (90 degs) so now the vertical ray's speed will change relative to the horiz ray (due to the shift in ether wind) hence making a different interference pattern at the detector as the physicist hypothesised.

(part 1)

Hm...i think there is some misunderstanding about the MM exp, so im going to try and clear it up. The aim of the MM experiment was to find earth's velocity relative to the ether (aether). As the ether was thought to permeate all of space, then as the earth orbited around the sun it will cause a wind known as the ether wind. Therefore (due to the direction of the ether wind), the speed of the horizontal light rays will increase/ decrease relative to the vertical rays. ----see continue

Look into Dr Nikolai A. Kozyrev

[CACBCCCU]

It's basically an impulsive aether jerk-meter, to be precise. It can detect a hypothetical aether dirift impulse (fittingly called here an "aether jerk") of around one millimeter or greater magnitude, but only if it happens in less than 1/4 the time it takes for light to pass through the device. Why, you might ask, can't people just use their brains to detect such an aether jerk - thinking it would be hard to miss. Well, I have no good answer for that. Power line interference? Loud noises?

[CACBCCCU]

There are four arms in MM's setup as shown here, all generated light goes in the first arm and all detected light goes out the last arm, light splits between the second and third arms, where it goes out and reflects back in. Frankly at this point the setup seems silly, a bit of an constant aether drift troll, since constant drift going out would be canceled by constant drift going back in. It's a real-time aether drift variation measurement experiment. An aether gust-meter. It's funny like that.

[EpicPilloww]

This is a decent representation of an interferometer and how it works, but the actual experiment itself wasn't demonstrated... :/

[Stupefience]

yeah but check out the interferometer page here sites.google.com/site/physicsp­hilosophyscience/home

My great great grandfather is Albert Michelson who won the science nobel price bitch's

[oscarvmaldonado]

ether does exist..hey get two magnets a + and a - and try to unite them, this force is the ether..HELLLOOOOOO...

[MrHay1001]

what is the point of the stone table and mercury, and how is it set up??

[MrChistes]

exactly

[goody8504]

all this does is prove that if ether exists, our assumptions about it are wrong

[afnangul]

FUCKING one

[SkinnyToMuscle]

this theory can't work 1st because the first ray of light splits in two (means one is reflected the other passes through then again the passed through light can't be reflected..

[kristiankroflin]

Nice simulation, but Michelson Morley doesn't prove nor disprove anything since the (polarized) "light" is too coarse

and the difference between the speeds is so small that it's

neglected for this experiment.

Something that seems to be completely o.t.: you know those moving LED signs, made out of single LEDs. From a distance letters and numbers and symbols seem to move but when you are near enough you see that only the LEDs are either on or off.

[idiotkrati]

So both of the lights enter the detector at the same time, showing that there is no ether ?

[w4Yp0iNt]

exactly

[ActiveStorage]

why cant the medium be static? so it wont affect the way the light moves?

[w4Yp0iNt]

what do you mean by "static"? I'm not sure whether this answers your question but actually this experiment was accomplished a few times, each time the table on which the experiment was built upon was turned a little arround it's own axis.

[ActiveStorage]

static means static aka stable. something that does not move. Think of a vacuum. Can vacuum affect how waves and particles move? Why cant ether have the same "static" properties of a vacuum?

[ardjan]

If the ether is static, then it should change because of the movement of the earth, our velocity is 180 degrees the other way, each half year. This means that the static ether will be moving half a year later. This is not the case. So, this experiment showed that the earth is not moving through the ether. They added ether drag to fix it, but Einstein showed that we do not need the ether and that light does not need a medium to propagate, because if it's particle nature.

[ActiveStorage]

sorry but Enstein didnt show anything. He developed a theory assuming that light can be a particle.

we still have wave-particle duality and none can do anything about it.

ether dont have to be just static or just dynamic structure. Consider water, or any other medium. It's a well known fact that such mediums tend to vary their dynamics based on the environment. For instance air layers can 'stick' to a supersonic fighter jet and move with relatively similar velocities creating drag

[nvsvictor]

I still don't understand one aspect. How does this prove that ether doesn't exist?

If ether existed, then we should see an interference pattern?

[w4Yp0iNt]

exactly

[nvsvictor]

So if ether existed, should we see an interference pattern when we rotate the platform with the interference caused by the water-like medium making one light wave distorted during rotation?

... and not see an interference pattern when the platform is still?

[jburnum]

watch Gruma09 channel. This should bring up some interesting questions.

[jeanforthewin]

@nvsvictor the reason it disproves the ether in one sense is because there is no SHIFT in interference patterns

also, it doesnt disprove the existance, it proves that it either doesnt exist or that it is stationary relative to the earth

[peeik]

@nvsvictor The exp was not to prove whether or not the ether existed. It was to measure earths velocity relative to the ether. Because there was no interference pattern, it made M+M confused and puzzled. Einstein then said it was not necessary to use the ether model to explain the propagation of light, instead he showed that light speed is constant in all frames of reference; thus explaining the same interference pattern regardless of rotation.

[rdsbarros]

@idiotkrati Not necessarily. The experiment can be interpreted how a proof by the Earth is immobile in aether. But this smells like geocentrism and the physics prefer to burn themselves alive instead to admit it. By this reason, we have the suspicious relativity's theory.
