Sorry for bringing up this subject again but I'm really just looking for some answers. This is strictly hypothetical. Suppose, for a moment, that humanity could somehow overcome these problems (disease, war, global warming, terrorism, etc) and advanced to a stage where it was limited only by the laws of physics. Let's say humanity somehow found a way to saturate the universe with intelligence and things like war and disease simply didn't exist. After countless billions of years, as the stars and suns are dying out and the universe becomes colder, what's to stop humanity from escaping to another universe, perhaps by wormhole, or creating a new universe, perhaps in a particle accelerator or something, and moving into it? Keep in mind that I'm not talking about going from place to place in this universe, but of going to another one altogether.
