Well they did thier sum and came up with one figure.
Then they produced telescopes and came up with another figure.They they built observatorys and the figure changed again.Then Hubble was created, and a woman a nasa came up with the figure that Lizzie mentioned, so thats it's sorted.
well at least untill they build a more powerfull space telescope that is. :-/
I reckon that you could be just the man to finally solve this age old question Skrunts...... 
In theory it's infinate, as there is no current way to prove it comes to and end or stops.
Look at this idea, we (earth) = a marble, put that marble in into a weather with a ball bearing an orange tennis ball (sun) a golf ball etc for the other planets. and call that our gallaxy system.
Now put that weather ballon inside a hotair type ballon and throw loads of other weather ballon gallaxy systems in there.
Then chuck a 100 hot air ballons into an even bigger ballon, you can never say where it might end.
We can only judge what we can see, hear, smell etc. So we look at insects under a microscope in a lab a 10x, 100x 1000x magnification and even more, but not so long ago it was just a magnifying glass, and before that the human eye, so all that time back it was probably nigh on imposible to count the legs on a centipede. but now it it can be blown up to 100x life size.
The military have satelites that can read a newspaper from space.
So 10 years from now we may have another theory, then a 100 years from now then yet annother.
Carbon dating for example is annother gray area. scientists say one thing, and 20 years later they contradict themselves. 20 years later, thier theoris change again.
So what you have to do is ask yourselfs, who do you trust, or what do you believe. either way there is no real way we will ever know the age of the dinasore era or the size of the universe (the name that it currently has)
Your round, mines a pint.
