Is this a truth and its evidence?

Hi,
I remember that long long time ago, I got that the time will slow down when one object does accelerate to be in light speed. What is the evidence to prove this?

Best regards

Sounds like the theory of relativity, there is a lot of evidence for this. Here is a list of some experimental evidence:

The phenomenon isn't exactly as you describe, but it sounds like time dilation, where an observer moving relative to a clock will see that the clock ticks slower than an observer at rest relative to the clock. This disagreement between two observers is strange, but it is not a paradox.
