But what's filling the space between the dots? Is it new space? If I have a long ass string, is the string gradually getting longer, or will it break apart?

But what's filling the space between the dots?
Is it new space?
If I have a long ass string, is the string gradually getting longer, or will it break apart?
- vecter 6y agoMore space. It's pretty nuts. Imagine you were stretching a rubber band. What's in-between two points on that rubber that was stretched? Just rubber, albeit thinner and less dense. In our universe, however, the space that's created is the same as the space that was just there. It'd be like if the rubber band stretched, but didn't lose any density while it did so. Insane, I know.
- Razengan 6y agoSo, is it like, the number of pixels on the screen stay the same, but it takes more “ticks” for a variable representing coordinates to go from 1 to 2: x += 0.09 instead of x += 0.1
- bencollier49 6y agoSo as the universe grows, am I growing as well? How much is the space inside me growing on a daily basis?
- bbbobbb 6y agoNo. The expansion is only apparent on intergalactic scale. On human scale, and even much larger scales, it does not overcome the fundamental forces. You're not expanding.
- dotancohen 6y agoSo, it was the donuts?
- insulanus 6y agoThe string won't break apart, because the forces that are holding it together are so much stronger than the "force" that is pulling our universe apart. Unfortunately, it doesn't answer your more fundamental question of "if I make 2 marks in space, and then those expand apart, what is in the new space, and how do I know they really are farther apart?" I have never heard a good description of this on human scales, only at stellar and galactic scales.
