Science Fiction writers have ‘solved’ the issue by imagining the Faster Than Light (FTL) technology, the FTL hypothesis starts out from the assumption that technological progress has no upper limit, something that violates Einstein's established paradigm.
Everyone knows this is impossible, but my ‘neural network by defect’ tells me it will finally be built by someone who didn't know it... or we'll stay here until the sun freezes!
Einstein, that sarcastic old man that makes fun of us by sticking out his tongue in the 1951 photograph I have on the wall, the man who elaborated the theories that close our way to the stars.
Theories that have been experimentally proven and that all scientists accept as the established paradigm.
For practical purposes it means that when the speed of a spaceship approaches that of light, its own mass grows until no engine is able to accelerate it further.
We can visualize the phenomenon as a vehicle that tries to climb a mountain whose slope becomes more and more pronounced until it can no longer climb and never reach the top.
But you can also drill a tunnel across the mountain.
In theoretical physics jargon the tunnel solution is called Einstein-Rosen Bridge, or more colloquially Wormhole, a speculative structure that would connect distances such a billions of light years, different universes or different points in time.
Wormholes are consistent with the Einstein theories and are projections of a new spatial dimension, that Science Fiction writers call Hyperspace, a place where the laws of physicals are different.
Consideration must be given to the possibility that the human mind is incapable of solving the problem. Nor do we possess lifting a ton of weight, flying, running at 100 mph, breathing underwater, or seeing Uranus, heat, or bacteria... but we've found a way to build machines that do it for us.
Maybe Artificial Intelligence will uncover the secrets of the FTL.
Perhaps biological intelligence is just a transient phenomenon in evolution.
