8. If a space ship travels at 80% the speed of light how time dilation does aff a board compared to an earth bound clock?

To calculate the time dilation factor, we can use the formula for time dilation in special relativity: where is the velocity of the spaceship and is the speed of light.Given that the spaceship travels at the speed of light, we can substitute the values into the formula: Simplifying the expression inside the square root: Therefore, the time dilation factor for a spaceship traveling at the speed of light is . This means that time on the spaceship will appear to move times slower compared to an Earth-bound clock.
