Farming Always

We can never know. There might be apocalpyse in the future. True. Although if we can successfully colonize another planet (mars, for example), we will increase our chances of survival in the long term by a factor of 200. This would be a great step in securing the future for our species. Infact, as most of you will know, we have a project underway that plans to do just that within the next 15 years.

If the human race manages to survive to the end of the suns life (5ish billion years), I would like to think that we would be masters of spacetime at this point. Multiple theories of how to make interstellar travel possible are floating around. One of the most promising is wormholes. Wormholes are black holes that exist on a fold in spacetime, thus existing in 2 locations simultaneously. They are still theoretical at this point, but that does not mean that we won't find them if they do exist. You understand what he is saying though 'Every Black Hole Contains a New Observable Universe' Happy? Edit: There can in fact be more than one universe and it is a theory that a lot of scientists are studying. These different universes have, in theory different constants than ours. The idea is that there are a seemingly infinite number of universes with a seemingly infinite number of constants, so for example, our Gravitational Constant is 6.67384 × 10^-11 m3 kg^-1 s^-2, but it could be 5.67384 × 10^-11 m3 kg^-1 s^-2 in another universe. You are correct. A multiverse is the most logical and plausible theory. However, finding a way to prove these parallel universes exist will be the real challenge. Many physicists will deny this theory, due to it being so hard to prove. Recently we saw some evidence pointing towards to multiverse theory. The microwave radiation left from the big bang was thought to be evenly distributed throughout the universe, but recent information from the Planck space observatory showed that our universe actually has a higher concentration of said microwave radiation in the southern half of the universe, which cannot be explained. Another interesting find was the "cold spot" which was also located in the south. These strange anomalies definitely hint at a very strong gravitational pull from OUTSIDE of our known universe. I do believe Laura Mersini-Houghton and Richard Holson, both predicted effects on the cosmic microwave background would be caused by the gravitational pull of another universe, back in 2006 (or 2005, I cannot remember). As for the theory stated in the original post, I find it very interesting. Will be exciting to see what more we can uncover about this.
