Is likelihood of asteroid impact infinitely big?

Hi.

If space is infininite, is there any real way of calculating the risk of an asteroid impact? Does the big bang expansion make us safer (more space per object)?

Since asteroids, comets and other bits & pieces traveling around in space can have their paths altered by the gravitational fields of other celestial bodies, it would take a computer model of such accuracy and super power to calculate the risk, I doubt if we could live long enough to set up the computer before we get a direct hit from something.

Doomed, doomed I tell you, we're all doomed! The end is nigh!

If you go to this link (http://www.theskepticsguide.org/archive/podcast.aspx?mid=1), and listen to #199, you will hear an interview with ex-astronaut Rusty Schweickart. He is now responsible for tracking meteors that intersect earth's orbit. It makes an interesting listen, and the upshot is that although there are many thousands of these objects that are as yet not tracked, it is not by any means an infinite number.
