My first thought is "OK, now put down the bong".

More constructively, while I too enjoy amateur philosophy, I think the further you stray into actual physics the greater your chances of saying something provably nonsensical.

I don't think the second part of your comment was any more constructive. Even if you don't agree with the basis or the the conclusions, there is value in these kinds of exercises. At the very least, it might give someone new perspective on their own ideas. Someone might stumble upon something useful.

IMO as long as we can't explain one of the most important forces that we experience, I don't think we should so casually dismiss these kinds of pursuits.

Seems like nonsense - always does when you resort to first principles.

I like to wonder, how do we know space is expanding? When particles get further apart, do they also grow in size? Then how would we know they are further apart? The entire system got bigger, including the ruler.

I know, we measure light and that's the ruler. So light doesn't expand too?

As far as I know, the evidence of expansion has everything to do with light. It's the Doppler effect. There is an apparent red shift (expansion of wavelengths) if you are moving away from the source, and a blue shift (compression of wavelengths) if you are moving towards the source. We see everything around us as red shifted, so it looks like we are raisins in a loaf of expanding bread. All raisins are moving away from each other, or the space in between raisins is expanding.

Was my exact sentiment too. I want the two minutes of my life back.
