# Is time runs faster at the top of a building or at the bottom ?

## Main Question or Discussion Point

Is time runs faster at the top of a building or at the bottom...?

what do you mean time runs faster?
Time neither runs faster nor slower..but passes by constantly.

No my dear

Time dilate
time is like a river not like an arrow

Okay..
Anyway, Time does not run fast or slow...it is always same unless you increase the movement of gear wheel in the watch.
But you may feel it runs slow at relativistic speed..
But why did you tell about building top and bottom..?

A clock at the bottom of a building will be seen running slow according to a clock at the top. The clock at the bottom is said to be gravitationally redshifted.

So what's the difference between "feel it run slower" and have it actually run slower? The proper time as measured on the watch of a person at rest with respect to an event will always
tick faster than a the watch of a person moving relative to this event. It has nothing to do with mechanics. Even the 'internal clocks' of muons that tell them when to decay are affected by time dilation.

Yes,
you may feel that time goes slow or fast...But it doent in reality..
Anyway a watch attached to the object (you are measuring time w.r.t. this object) gives the right value..

Yes, it does. It's called time dilation. It has been experimentally verified.

@Rajini: ...A very long time ago... Some clever lads took a cesium clock in an airplane and compared it to another on the ground. They found a measurable difference due to gravitational and (regular?) TD/DA. You need to study Gravitational Time Dilation.

Hmm,
verified by Mössbauer effect!
