Is it possible that multiple big bangs happened at the same time infinitely far away from one another? If so, when will these systems expand into our view?

No. The Big Bang was not an explosion, it simply marks the beginning of time where space time expands. This is not something we could observe, because time has already begun, and entropy cannot decrease.

Ok, that's cool. Just wondering, then why do systems move away from each other so fast. Also, i guess you don't believe in the big crunch

Edited by The Cellar Door: 4/6/2016 4:47:25 AMAssuming by systems you mean galaxies and clusters, the space between them is exponentially expanding faster than the speed of light. And no. Heat death.
-
Exactly, if there was no explosion, what gave them the velocity to move so fast?
-
Spatial expansion. They're not moving away from each other, the space between them is growing at an accelerating rate.
-
If how does nothing expand on its own? Much less move entire systems?
-
It's not pushing anything. The space itself is literally getting larger. Why this occurs is a very great question, and I would love for you to help the effort in figuring out the answer. Nobel prize, millions of dollars, hot chix, the whole package deal comes with the cosmological constant.
