I have make many threads about this topic because I am really interested. I reading that from an pdf,but I have some "idiot" questions too.


1)A guy told me that If you run in other speed from an other you see his clock slower.
I have hear about paradox of twins,that this with biggest speed grows slower.
Then how is possible to see the clock of his "old"(that grows faster) to go slower from him??


2)If we are a neutron,and we run between a photon with 99% of its speed,how we would see that?
(it will be the same?We would see that run with 300.000 km/s or with 1% of its speed?)

This should explain it: http://en.wikipedia.org/wiki/Twin_paradox
The basic explanation is found in the very first paragraph, with more detail in the rest of the article.

From the frame of the neutron the light will move at c. (300,000 Km/s)
