Ok, so I'm mixing up mass and weight. But if you took the mass of the universe and put it on a scale in a 1-G gravity well, how much would it weigh?<br /><br />I ask this rather silly question because I've heard it said that if the universe has sufficient mass then it will collapse back into a big crunch but that if there is not enough mass it will expand forever and cool off into nothingness. I've also heard it said that they haven't been able to find enough mass in the universe to keep this second scenario from happening. Therefore, one might presume they know what the universe weighs based on detected mass.<br /><br />Ok, so how much does the universe weigh? <div class="Discussion_UserSignature"> </div>
