      Space is ever expanding after the big bang which took place about 13.6 billion years ago. To really get an idea of scale, have a look at this link where you just move the wheel of the mouse to zoom in or out : http://apod.nasa.gov/apod/ap120312.html

      Space is pretty much infinite. We will never reach the edge of theuniverse as it is expanding all the time.

      Space is so big it’s hard to really think of it’s size and imagine it in your mind! The universe is constantly expanding and it looks like it will continue that way forever. It’s hard to describe but the universe is expanding in a way that each point is expanding away from the another point at the same rate. This means that if we pick a point in space that is at a certain distance away from us and another point which is an equal distance away from the first point we picked it is moving away from us at twice the rate. This continues on until there is a point in the universe that is moving away from us at faster than the speed of light. That means light from that region will never reach us so we will never ever be able to see it…. space is HUGE.
