why time decelerate if we have very high speed n why gravity effects time?

Question

i heard on top of high mountains time pass slower.?how come gravity effect time?

Answer 1

The speed of light is relative to all observers, so when you travel very fast (like near the speed of light), you will still see light travel away from you at the speed of light. A stationary observer will see you and the light travelling at nearly the same speed. Time slows for the person travelling near the speed of light simply because of the laws of physics. For the speed of light to remain relative, the time you experience will tick at the normal rate, but once you arrive back to where you started, you'll notice the time shift. For stationary observers, your time slows down.

Gravity effects time because of the effects of "frame dragging". Since space & time are intertwined, the fabric of space and time is bent by gravity.

Answer 2

That would be incorrect, the higher up you are the less gravity has an effect on you, and the less it effects time, actually the closer you are to the center of the earth (in a valley) the more effect gravity has on you.

Gravity by its self does not slow time, its a seconday effect of a mass bending space, in which gravity is result of the warping of space by the mass.

On the subject of time slowing when speed increases, its has to do with relativity. As you increase your speed your mass actually becomes greater and as mass increases so does the warping of space, you wont notice the mass increase because of the speeds humans are capable of it is a small effect, but we have atomic clocks that are accurate to the 1000th of a second on satillites orbiting the earth and they have been shown to slow down a tiny amount and fall behind other atomic clocks that are down on the ground.

Answer 3

First, time doesn't pass slower anywhere, it just may appear to pass slower/faster when compared to another frame of reference. Within your frame of reference, time would always appear to 'move' as it should. I'm not qualified to explain why it occurs, and it certainly couldn't be explained fully here, but in a nutshell, the greater the force of gravity in a location, the slower time passes in relation to another location that experiences a weaker force of gravity.

On top of mountains, clocks would actually run FASTER than clocks on the ground, because clocks on the ground are a little closer to the center of the earth and therefore the force of gravity greater on the ground. The difference between clocks on the top of a mountain vs. clocks on the ground would be very negligible (in nanoseconds) but would still be present.

Answer 4

Time is altered by speed not gravity.

A clock moving at 22,000 MPH runs slower than one on the Earth. But not by much.
