Earlier quoted context omitted.
The entropic heat death of the universe comes more from the notion that R=1 is implied by the conservation of energy and so while the universe might stop expanding at t=∞ the average energy of any particle at that time will be 0. if R>1 same thing but faster. The other option is that we all die and then the universe collapses... which is just as final for anything hanging around as heat death would be.
The entropic heat death of the universe comes more from the notion that R=1 is implied by the conservation of energy {facepalm} Physicists already know that on the scales of the universe, there is no conservation of energy. I hate to break it to you folks, but most of you are dead wrong about conservation laws. Conservation laws are a fundamental part of your education, but they are not a fundamental part of the univ…
It’s also worth pointing out that universal expansion has an effect only on distance scales larger than galaxies. There is no reason to believe it will pull apart smaller structures, never mind subatomic ones. It’s a popular misconception that the expanding force is great on small distance scales. On the scale of a galaxy, that force is overcome by gravity, so needless to say the Strong force won’t even notice it.
Tl;DR Metric expansion is a powerful cumulative force on giant distance scales, weak on small (below galaxies) scales. Galaxies, stellar systems, stars, and Hadrons will be just fine, thanks.
If you’re going to scold people, you could at least be right. It is also a good idea not to rely on just YouTube videos for your arguments.
