“After the “first few microseconds” the universe was still fairly tiny? “
If that was the case then both time and space can be compressed, making both intergalactic and time travel possible.
Or, it does to my simple mind.
Which then raises another question, what’s on the outside of the exploding bubble known as our universe? Is absolute nothing possible?
The universe is defined as "everything". Nothing supposedly exists outside the universe. Is that possible? How the heck should I know???
