## How do you explain time dilation?

Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer. Suppose, for example, an astronaut measures the time it takes for light to cross her ship, bounce off a mirror, and return.

## Is time dilation symmetry in general relativity?

Einstein’s Special Theory of Relativity (SR) relates time dilation to the velocity between the observer and the observed object as if they are identical. Our new theory breaks this symmetry by relating the velocity of the object not directly to the observer, but instead to the center of gravity of object and observer.

**Is clock symmetrical or asymmetrical?**

It is asymmetrical and it occurs when a reference frame has a speed faster than the other one. There is also the time contraction and occurs in the reference frame that has a slower speed with respect to another reference frame.

**How did Einstein explain time dilation?**

Time dilation One of the many implications of Einstein’s special relativity work is that time moves relative to the observer. An object in motion experiences time dilation, meaning that when an object is moving very fast it experiences time more slowly than when it is at rest.

### Why time stops at the speed of light?

In the limit that its speed approaches the speed of light in vacuum, its space shortens completely down to zero width and its time slows down to a dead stop.

### Why is the twin paradox asymmetric?

Many authors claim [2] that the asymmetry is due to the accelerations the traveling twin is undergoing at the start, the end, and the turning point of his journey. But one can also formulate the paradox without making any reference to accelerations. It becomes then a purely kinematical problem.

**Is time dilation a reciprocal?**

Time dilation is reciprocal because moving between two observers is reciprocal. So the following two statements are both true: Elapsed time a moving clock is dilated (longer) when measured by a stationary observer. Elapsed time a stationary clock is dilated (longer) when measured by a moving observer.
