Why doesn't our solar system run into other solar systems over billions of years?

Question

Why doesn't our solar system run into other solar systems over billions of years. There is plenty of time for it to be attracted by gravity to other objects. So I thought, it should be a common occurrence? or is there a reason it is not a common occurrence?

Answer 1

Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
