According to Special Relativity

Δt' = Δt / √(1 - v

^{2}/ c^{2})^{8}). The factor - c (speed of light) comes into the picture because the entire theory is based on special relativity, which has constancy of light speed to be its central tenet. The above equation states

**. This is a consequence of the fact that time is relative and local in nature and not absolute for all.**

*that the faster the spaceship moves, slower will be its running clocks*According to General Relativity

*Spacetime Physics*' by Taylor and Wheeler, which is highly recommended reading, if you want to explore the beautiful and astounding theory. For understanding the general theory of relativity, you will need some mathematical expertise in differential geometry and tensors. A good place to learn it from is '

*Spacetime and Geometry: An Introduction to General Relativity*' by Sean Carroll. However, know that this is an advanced physics text and will take some hard work to understand. I can assure you that it will all be worth the effort.
