Yes. Mister. K is right. Relativity is basically about how gravity affects time.I was unaware of that. I always thought relativity had more to do with time itself. I was looking it up just to confirm if I was thinking on right terms and came across gravitational time dilation. Apparently time passes at different rates based on gravitational potential. Boggling stuff really.
When someone says "relativity", you should immediately ask them to qualify it. Special or General?
You were right in that special relativity does deal with time. General relativity deals with how gravity affects time.
It's very important to understand frames of reference when understanding special relativity.
As a simple example, even if you are just sitting down, you are not completely stationary because earth is still revolving and orbiting. Everything in the universe is in motion already. How fast or how slow is what is relative.
