The question that has been bugging me, and others here, is one that says everything in the universe is expanding, not just the space in-between stuff. But this is illogical for if, say, a proton popped into existence when the universe was only the size of, say, a grapefruit, it would be easy to see protons today if they expanded as much as the universe has (to ~ 96 billion lyrs in dia.), right? This would, of course, present all kinds of issues.
But there is the issue of particle duality. It's both a wave and a particle, sometimes called a waveicle. So, in Laura Mersini-Houton's book, "Before the Big Bang", she mentions that it is the wave portion that gets stretched not the particle aspect of it. This has the effect of cooling everything as well.
I'm not sure I truly understand it since wavelength determines energy, so are, say, electrons much wimpier today than they used to be since their wavelengths have been incredibly stretched since they formed during those first 7 minutes? This kinda works if we set one energy amount for the particle, and another for its wave properties. Why wouldn't they be cooler today?
