Gravity

We all know there is no such thing as zero gravity even at the very end of universe there is micro gravity according to formula for gravity…!
Means we are away from certain object so the gravity exist in vacuum so now my question is:-
Q- We all know that there is zero Gravity in center of earth core so if we place an object in center of earth the would Gravity formula apply on that object or that object is in complete Zero gravity…????

Answer:

 

If we simply keep a body at the centre, it will remain there as it is attracted equally in all directions.

Escaping from gravity

Hello everyone,

Plot of a two-dimensional slice of the gravita...

ever since I heard of the concept of a gravity well I’ve had a great deal of trouble coming to terms with the fact that gravity’s actual pull in infinite ( though admittedly very small at large distances due to the inverse square law ). Is there any way someone could explain to me how it is possible to escape the effects of something with infinite range?

Speed of Gravity

Why hasn’t anyone measured the speed of gravity yet?

As in, how long does it take for the gravitational field of a mass to affect another mass?

Answer:

Gravitational Lensing in Galaxy Cluster Abell 37

Who said that speed of gravity waves is not measured?
