I know time is Flexible . But I don't know how gavity slow down time? And How much it slow down time?
Can anyone explain this for me?

Hi John, here you are.
What is gravitational time dilation
How and why is a bit of a mystery.
There's also  Gravitational time dilation  Wikipedia, the free encyclopedia
Around a nonrotating, uncharged, spherically symmetric distribution of matter, spacetime is described by what is called the Schwarzschild metric. For details on this (mathematical object) please see
http://rogachev.dyndnsathome.com:8...%20Metric).pdf.
This metric can be used to derive the relationship between the rates of two clocks in a gravitational field which are located at two different gravitational potentials which in this case boils down to two different radial coordinates, r.
They're related by
where and are defined as
= Time increment as measured locally, i.e. by observers located at r
= Time increment as measured by Schwarzschild observer, i.e. an observer located far away from the source.
in reply to Johnzxcv, re: your #1 post.
Gravity does not affect time...it affects matter. We measure the affect/effect values as "movement prorated over time".
Cheerio!
The presence of source of energymomentum affects the way measurements of space and time are related between events in the vicinity of these sources. This relationship is quantified using the metric, and in the particular case of time it is the (0,0) component of the metric tensor that is relevant :I know time is Flexible . But I don't know how gavity slow down time? And How much it slow down time?

How much clock readings are dilated with respect to some reference point at infinity hence depends on the metric  note that most formulas you will find on the Internet specifically relate to the Schwarzschild metric, but when you consider different spacetimes ( such as the more general KerrNeman ), these formulas will change accordingly. The above is the general relation between coordinate ( stationary at infinity ) and proper ( physically recorded on a local clock somewhere ) times.
