Physics, Astronomy & Cosmology / Does the Fermi paradox suggest that superluminal speeds are unachievable?« on: 15/08/2019 10:52:30 »
While pondering the existence and consequence of faster than light particles, I wondered if tachyons are real and useful then we can travel the galaxy in years rather than in millennia. Then, given the large number of planets capable of supporting life, another civilization would have harnessed the ability to travel interstellar distances easily. However, as Enrico Fermi pointed out in his famous lunch time paradox, we have seen zero proof of alien contact. So, either advanced extraterrestrials don't exist or exceeding light speed in space travel is impossible. Any thoughts on this?
