Yet, without stellar content, journalism 2.
March 12, at He brings up, as a possible solution, that this is about the number of times a beam of light could cross an atom since the begining of the universe, so maybe the ratio increased over time.
But then he notes that this means gravity would have been significantly stronger in dinosaur times, so we should have noticed it geologically or cosmologically. You can do this for some simple alternative rules of physics.
The emission spectra of the elements that their stars are made out of are the same as the emission spectra of those elements here on Earth, so that can restrict how different things could have been.
If the speed of light were faster in the past, then that would prevent us from knowing how long ago something happened based solely on how far away it was, and so the theory would be mixed in with the very observations that were trying to test it. There is an extra point, which is that time-symmetry of the laws of physics has consequences for other laws of physics.
So if we saw violation of energy conservation, that would definitely make physicists think twice about whether the laws of nature were the same at all times. But, since we have always seen energy being conserved, this is evidence that the laws of physics are the same at all times.
If you reverse the direction of time, physics only stays the same if you also swap particles for antiparticles, and flip space into mirror image of itself as well.
We had a colloquium speaker discuss this recently. The Nybbler March 12, at We can always assume the last magic act was to hide all the evidence. Generally, the constant everyone tries to measure is the Fine Structure Constant.
Variation in the fine structure constant has to be due to the laws of physics varying. There have been lots of efforts to measure whether the Fine Structure Constant varies in the distant past. There have been a few studies finding a very small but non-zero variation, but my impression is that the majority of studies like this recent one… https:Here are the top most common Arabic benjaminpohle.comly, 5, to be exact.
