If the universe expanding why we are not collide with other universe or other elements on space?

Question

If in the point were bigbang originated many elements was formed, that all compose our universe.Im sure these elements also be found at any point here in this infinite space.So is it possible that there is interaction of different elements with our expanding universe to cause massive collision,and explosion at any time?

Answer 1

You've asked this before...
The Universe doesn't work like that, the Universe isn't actually expanding INTO anything, it is merely getting bigger.

The Universe as we know it is Everything, there is nothing beyond it, not in any meaningful way, at any rate.

Answer 2

As space expands the galaxies move farther away from each other so the chances of a collision gets less.
Galaxies are likely an end stage in the evolution of the universe so they likely stay remote from anything else.

Answer 3

There are collisions within our Universe due to this expansion.
Galaxies collide, tearing themselves apart, or even merging together. In fact the Andromeda Galaxy is heading towards us and will eventually, in a couple of billion years, crash into our own Milky Way.

Answer 4

Collisions of galaxies do take place, they are merges more than collisions. Local gravitational influences cause one galaxy to move toward another, but because the distances between stars of galaxies are so great, collisions of stars are very rare. Colliding galaxies take on different shapes and eventually go their separate ways.

Answer 5

The Earth has only collided with small object. But the possibility of collison with larger masses does exist.
note what happened to Jupiter.

Answer 6

Actually our universe expansion has no reach that part when, maybe in a thousand, million, or billion years, it would happen. When it happen it would cause a super nova that would probably destroy our universe, or people would say, causing a rip in space.

But what would I know I am only 15...

Answer 7

Space is mostly empty.
