I just the last one scrolling down. The answer is yes, though the “if” is a very big one since it appears you’d need infinite energy to accelerate anything with mass to the speed of light.
In relativity the speed of light (c)is constant no matter how you look at it. So, if you turned on your headlights while travelling at c they would light the way for you. Much more interestingly, if someone was standing somewhere else watching you perform this experiment they’d agree that the light traveled at c, not 2c as you might expect. This uprising result arises because time is not constant in special relativity, but appears to slow down in a fast-moving “frame” from the point of view of a stationary one. So the observer watching you turn your headlights on thinks you get the result you do because the “clock” with which you have meausured the speed of light has slowed down (or, in fact, time has slowed down).
Such time dilation is the reason that astronauts are a fraction of a second younger than they would be if that hadn’t been to space (they are time travelers relative to us), and needs to be taken in to account of to correct GPS satellites (which would lose about 10 km of accuracy each day if they didn’t account for this effect!).
So, that was pretty easy right?
