What happens when you reach the end of space?

It will expand forever; the galaxies within groups and clusters will merge together to form a giant super-galaxy ; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes ...

Does space have a end?

Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. ...

Do wormholes exist?

Physicists believe wormholes may have formed in the early universe from a foam of quantum particles popping in and out of existence.

What is the deadliest thing in the universe?

The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.

What is bigger than a universe?
