That's what they tell us. Light can travel through a vacuum with nothing in it. And maybe so but what is the evidence?
So I looked up the best vacuum on planet Earth. It contains 2.5 million molecules of air per cubic cm. This is said to replicate conditions between stars. So how then can we say we've ever tested light waves going through "nothing". We haven't.
To test the validity of my suspicions I've asked the science guys on reddit if they have an answer for this. The first few responses have already been hostile and that usually indicates this is one of those issues they simply don't have a good answer for. I was very polite in my question btw, so no I didn't provoke anybody, this is all on them.
We'll see how it goes. I'm open to a good explanation of why this is a valid test, but this light has 2 million molecules to interact with ever cubic cm it propagates, so you didn't rule out matter.
Just to clarify - you think the interference pattern found in stationary rlgs and the gale pearson are due to wind far above the detector? If so, would you not expect the interference pattern to vary when the wind speed (inevitably) does?
If you are saying that no interference pattern is detected with the wacky spinning spindle rlg - then that is certainly interesting. I wonder if the pattern returns as you slow down the rotation of the spindles - since without that rotation, this seems to be a standard rlg setup.
Perhaps, but it failed to find it in any case - presumably due to its configuration (straight legs, right angles)
Perhaps it cancels out / affects both paths equally - but it would certainly affect the fringes.
And what was the result?
