ok, so i have watched tutorials on relativity, and other videos and such. looked at wikipedia but it has a lot of stuff i dont understand, and other places too. i could read through other posters questions, but im not sure how to really phrase my question and so i dont know what to look for, so i will try to say it here and hopefully somebody can make sense of the madness (my madness). so if a rocket is travelling the speed of light (assuming it could) and following an arbitrary path from the earth back to the earth where the elapsed time for the rocket people is X. time moves slower for him relative to people stuck on earth at a time i will call Xe, which is going to be less than X. Is that right? now why is this? i guess space and time are related and so i get all these videos and things telling me that all objects have mass and ca bend space and we can see that effect through time. So what? does that just mean that space and time are related? so then i guess that if you travel at light speed (hypothetically), then you move through space faster, so you would pass through time faster because it is the same medium, is that right? i mean is that the point of special relativity?
