No need to be snarky and especially not here re basic science. Time dilation happens exponentially, ie with 0.5c you don't have time going 1/2 slower, rather a miniscule amount. Once you keep approaching speed of light closer and closer, all things go extreme (time, energy required, mass and so on).
