How Can Time Be Relative While the Speed of Light Remains Absolute?

[Star786]

I'm really confused!
How can time be relative and speed of light absolute?
If you were moving a long with speed, whilst someone else was stationary would you not measure light to be slower??

I will take the two questions in reverse order. "If you were moving a long with speed, whilst someone else was stationary would you not measure light to be slower?? "
No.

"How can time be relative and speed of light absolute?"
Do you have any reason to think that the speed of light is relative and time is absolute? People only have problems with this because the opposite is intuitively obvious to them. Unfortunately, when it comes to things we do not have everyday experience with, what is and is not intuitively obvious is irrelevant. There is no reason why nature would behave in a way that we can understand. If you are going to think about physics seriously, it is something that is worth getting used to.
