How Big Is Our Universe?

[dcunning30]

Astronomy fascinates me. How we can predict what is going to happen in our lives by looking at the stars baffles me...

Might you be confusing astronomy with astrology?

I like to think that a universe is just another group of stuff, as in the are more universes outside the influence of ours.

why would everything that ever was be in one area at one time and why would it explode if it is infinatly dense and infinatly small

I can garantee there is life out there, 400billion stars in our universe, even if you figure 1% has a solar system thats  4billion and a portion of those could have multiple planets.

we are just insignificant specs in the whole ? thing!
