initiate Posted April 2, 2015 Posted April 2, 2015 I just had a small question about relativity. Say there is a universe that happens to have the exact same physical constants to our own except 1, their c is equal to 2 times our c. Could such universe permit particles with mass to travel at speeds that are considered superluminal to our own universe?
Strange Posted April 2, 2015 Posted April 2, 2015 Yes, massless particles such as photons would move at "their" c. Massive particles could move at any speed up to that. 1
