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…????

 

Asked Pratik Bhoir

 

 

 

Answer:

 

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

GRAVITY

 

Are all theories of Physics based on a mathematics … ?

Are not all theories of physics (general relativity, quantum mechanics and other variations) based on a mathematics of structure? An assumption that the model and its constituents have structure? Structure that assumes space as a necessary, though maybe not formalized component?

English: Quantum black hole Русский: Квантовая...

Could it be that during a black hole collapse that ALL structure is lost? All space is eliminated.  There is no space, only mass/energy?

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:

Who said that speed of gravity waves is not measured?

Please go through the links below and you ca get details,

Electron behaviour

An increase in energy level from E 1 to E 2 re...

Why an electron in level N when it gain energy it go to a higher energy level , why not going to a lower energy level , considering that word “higher” and “lower” refers to no of energy level but the energy of the energy level decrease as we go away from nucleus so an excited electron that gain an additional energy transfer to a higher energy level in no but lower in energy so why the electron doesn’t from its level to a lower energy level in no but higher in energy so the new energy level can bear the energy of the excited electron ?
(Moumen asks)
The question is not very clear. If you can explain it further, it will be better to discuss here.
