Something to do with the universe expanding faster than gravity could ever hope to pull things together right?
No, the universe is expanding. No magic required.
it’s actually a shrinking sphere. as the expansion accelerates, more space moves out of view.
Depends if the expansion is accelerating or not.https://www.youtube.com/watch?v=gEyXTQ9do-c
https://en.wikipedia.org/wiki/Expansion_of_the_universeThe expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "
Prepare to have your mind blown: https://en.wikipedia.org/wiki/Expansion_of_the_universeTLDR: expansion of the universe doesn't care about the speed of light and the universe is believed to have inflated very fast in its early moments
How about the expansion of the universe?
Isn’t this what is happening in our universe as well? Space is expanding faster than light can traverse it?
Why aren't all objects taking part in the expansion of the universe? Don't our ears move farther apart (ever so little) due to this effect?
the universe is expanding, after all...
