What Is Time Dilation?
Time dilation is the slowing of a clock moving at speeds close to the speed of light. It is a consequence of the theory of special relativity.
How is it calculated?
How Is It Calculated?
t = t₀ ÷ √(1 − v² ÷ c²)
- Enter the proper time and the velocity.
The effect becomes pronounced as the velocity approaches the speed of light.
Frequently Asked Questions
Is it noticeable in everyday life?
No; the effect only becomes measurable at speeds close to the speed of light.
