The closest Galaxy to Earth, Andromeda, is 4 light years away. It would have taken 8 years to just go and return at the old speed of light. Now science has developed Neutrinos that can travel 10 times faster than light. Which means that we can now develop a rocket that can take us to the next galaxy in just 150 days. This new discovery over through physics, astronomy and and distance in the universe, on the now, false assumption, that light speed was the cosmic limit.
