Scientists do have an open mind. However it is only open to things that don’t contradict existing experimental results. Relativity stands up well to experiments, so anything that replaces it will still be very similar.
And how does a “really powerful rocket” counteract experimental results?
All you need for interstellar travel without breakthroughs in physics is the ability to sustain a self contained ecosystem in your craft.
Humanity already has plans to send probes to Alpha Centauri, and the only technological price of that puzzle that’s missing is thinner solar sail material.
That is a close system. The universe is big. Odds are no alien lives close enough for solar sails to get here in the lifetime of the universe or galaxy.
