## How do you explain time dilation to a child?

Time dilation says that time will pass slower for someone traveling near the speed of light relative to someone standing still. As an example of time dilation, let’s imagine you left on a space flight today.

## What is time dilation in simple words?

time dilation, in the theory of special relativity, the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock.

**How does time slow down when you travel faster?**

As light is spread out by the observer moving away from the source of the light time is decreased. The faster the observer moves the more light is spread out and time slows down. Time slows down as you travel faster because momentum bends the fabric of spacetime causing time to pass slower.

**What is the time dilation at the speed of light?**

At speeds of less than 10% of the speed of light (0.1c or 30,000 km/sec) time dilation is miniscule, but from 99% speed of light up it increases asymptotically towards infinite.

### Has time dilation been proven?

Physicists have verified a key prediction of Albert Einstein’s special theory of relativity with unprecedented accuracy. Experiments at a particle accelerator in Germany confirm that time moves slower for a moving clock than for a stationary one.

### What is 90% the speed of light?

time dilation

Beyond our solar system, the next closest star system is Proxima Centauri, and it would take more than two years to get there at 90% of the speed of light. This time differentiation is called time dilation. This is a fact of space travel that forms part of Albert Einstein’s theory of relativity.

**Is time Travelling backwards possible?**

As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.
