serious question about the world

In order to actually move yourself at the speed of light, your mass would have to be zero to achieve that, or it would take infinite energy to get to that speed. So it it'll never happen.
Unless of course, some trick will have to be thought off first that 'hides' or fakes your actual mass to be zero, to the world, universe or better; spacetime, so you could travel that fast.

Another little bit of annoyance could be that time for you is ticking slower, or pretty much standing still if you actually travel at lightspeed.
While the universe around you is ageing at it normal current (relative) rate.
