hey my name is nick im very new to this kind of thing. i just had a few questions about the end of the known universe, dark energy and dark matter and how it will end the current universe. first of all i would like to ask a couple of my own questions. 1. ok, so the big bang created or expanded the known universe? 2. do we know where the center of the known universe is? 3. if we dont than is it possible that due to the size of the of the big bang there could be an area in the universe that has unthinkable amount of gravity from wich not even light cannot escape creating an orbit for the universes many galaxies and therefore creating the illusion that the universe is expanding?(much like how our galaxy but on a larger scale) if i sound stupid in any way please correct me and if there is anyone out there that can help me that would be great. im very, very new to this so go easy on me.
