How does gravity affect time?

Question

black holes, time travel,seperating space and time, then warping the "timeline"

would it be possible to bend time?

Answer 1

Think relativity - in this case, general relativity. High-energy situations cause an effect known as time dilation - time moves more slowly for the high-energy frame of reference than for a lower-energy one.

In the case of general relativity, the energy is provided by your position in a gravity well. Take two objects, A and B, both equidistant from the event horizon of a black hole,. If A starts to move into the well, then returns, less time will have elapsed for A than for B. The same thing will occur for any two objects in a similar position, regardless of whether the gravitational field is as strong as a black hole's or not - it'll just be more obvious with a black hole.

It's important to realize that time dilation really means very little without a frame of reference to compare it to. If A never returns to B's position so they can compare clocks, then it doesn't really matter all that much whether A's clock is "slow" or "fast". It's actually the acceleration of A's frame of reference that causes relativity to poke its head up in the first place.

Answer 2

Experiments have been done to see if Einstein's predictions about motion and gravity affecting time. Extremely accurate clocks have been used to determine those effects. In one experiment two cesium clocks were synchronized and separated. One was placed at the base of a tall structure while the other was placed at is top. After a week, the clock at the top was behind the one left near the ground--i.e. the one closer to the earth's center or gravity well.

Answer 3

Gravity slows down time!
However, gravitational mass can create a slight blend in space/time fabric as is discussed by Einstein in his book The Evolution of Physics. The introduction of a cold air blast also has an effect of contracting space IN FRONT OF THE OBJECT if the air behind the currently moving objected is heated creating an EXPANSION!

Answer 4

hi. i ll try to answer this question. But better way is to understand Einstian's theory of Relativity.

any thing traveling in the space will take a curvature when it is influnced buy a gravitational force. and the curvature is the path having least resistance.

in a graph of time and space, Time will be a stright line when there is 0 gravity. time will be deviated with incerase in gravity.

So as u know trvelling in a stright line will take shorter time than travelling in curve.

refer to theory of relativity

Answer 5

Gravity has the ability to slow down time. In fact in the presence of infinite gravity. for example at the event horizon of a black hole time in fact stops completely.

Answer 6

I don't think that time can be defined within our limited scope based on earthly knowledge. I do also have a theory that our solar sytem is part of a cosmic eddy, like a whirlpool, whirling ever closer to an imploding sun. That pull and the resulting spinning of various celestial orbs causes our gravity. As far as the other topics..............

Answer 7

The same way it affects everything else. Especially the other three forces in the universe. The strong force, the weak force, electromagnetism, and gravity are the four forces that govern our universe. And consider the source, GOD.,seriously.

Answer 8

Gravity speeds up time while dark energy acts as a repulsive force (anti-gravity) and slows down time.

Answer 9

RELATIVE TO ANOTHER OBSERVER time does slow in a gravitational field. See this website for a great presentation of the subject (...hell, even I can understand it)

Answer 10

gravity is -9.51 m/s. therefore, a free falling object maintains a constant acceleration, therefore time is essentially not an issue with gravity.
