Unless they come to us, meeting our neighbors in adjacent galaxies will likely not happen anytime soon. It has been speculated by the former director of Skunkworks, Ben Rich, that we already have the technology to go there, however if we do it is still too secret to share with the public. One of the ideas for intergalactic travel has to do with gravity and traveling within a gravity bubble. We recently discovered that NASA, DARPA, MIT and the Air Force all met in an online meeting to discuss gravity as a form of propulsion. This conference was titled Alternative Propelled Energy Conference and you can learn more from our friends in Italy, HERE.
