Reply to comment by lego_office_worker in Extragalactic SETI looks for life beyond the Milky Way. But where? In game theory one solution is a Schelling point — a single event that draws different group's attention. A binary neutron star merger could act as one, because observers across the universe will all be looking in the same direction. by EricFromOuterSpace

Without faster than light travel that would be impossible to prove since the universe is alot bigger than just the observable universe. With the speed of expansion increasing and already expanding faster than the speed of light, it would get harder and harder as our technology improves.

You probably would need to make distance a completely negligible factor in travel for this, you would have to make it so you could travel instantaneously to visit the complete opposite of the universe. The problem is, obviously these galaxies on the other side of the universe probably are moving away from us at a ridiculous velocities, to the point that you could not catch up to them perhaps.

You would some how have to have the energy to accelerate to FTL and likely not stop accelerating at any given point for x amount of time to outpace the movement of the galaxies.

I feel like some manipulation of quantum physics or dimensional science could be the real route for space travel, i don’t believe physically travelling point A to B is our real end goal.
