if we were able to move at the speed of light (somehow) how would things change due to the relativistic effects. Take this for example: if we were to go somewhere moving at 100 percent of c,and for simplicity say that it's 100 light years away, what would we feel or think? i know if we were moving at anywhere lower than c for example half of the speed of light our perspective of the spacetime don't change, meaning that we don't see ourselves smaller and that time doesn't seem to go by slower but someone stationary observing us will see our actions happen in hyperslow motion. And since time doesn't goes by at the speed of light meaning that a photon won't age a bit since the big bang what will happen to us. Will we be frozen in the same frame? will we reach our destination in an instance from our perspective?
