DIFFERENT TIME DIFFERENT ROLE

-
 An apple fell down from tree on newton's 
head and  result all we know as gravitational
Force.
Two bodies separate by some distance feel
gravitational force but in reality when 
mass of bodies  small then thier gravitational
Force so weak so we can  not feel this force
among us.
So gravitational force propotional to bodies mass and reciprocal squre of distance 
between them. If u double the distance 
Between two bodies so their force between them will be quarter of real distance force.

By this force

Everything is controlled in universe. Planets and astroids round the sun and moons orbit
Their planet and also satelites round the earth  only by this force .
          Gravitational force nature attract mass
So this process always exothermic process. Gravity also play a great role in build up stars.
          Gravitational force depend also their desities.if density goes high so there  force between them also goes high but when force in  limit everythink is ohk but if force is more more high so this force distroy everything...
       If you think about blackhole which have more more high dense mass so its gravitational field is more more high. So force between any body and black hole also more more high and consequently body falls in black hole.
       The gravitation  pull by black hole is so powerfull that enen light cannot escape. As we all know gravity does affects light so due to gravity time slow.
     So you can imagine what a force ! Light cannot escape.
       
     It is gravity...........
      Gravity control all motions and also sometime distroy them.
      
      So it play a different role in different time.

Space-time and curvature

Space time shape hard to visualize. Space time is  not constant like our earth surface. It's shape depend on mass of the object.            Take a example of a trapeze artist and their safety net.you can imagine a trapeze artist falling into a net on purpose that the net is flat and looks like space but when they fall into it they distort that grid well  that's a lot like space if you have matter in space it wraps the fram work when the trapeze artist is resting in the net they are bending that space - time grid little bit if you had 2 trapeze artists there double the mass in roughly the same volume .you have a bigger distortion and that's how space -time works. Space is bending like trapeze artist rest In the net and safty net get bends. In space there are plannets , stars , blackholes , nebulas and many more. These have mass so as trapeeze's safety net, space also bend .how much space bends depend what object's mass . More object mass more bendi...

      Neutron stars : if you want to know about how are neutron stars formed ? , how gravity affects the star ? And many more about neutron star so this post for you. Read this post from start to end.           Formation of neutron stars Neutron stars are very tiny with almost 10 to 20 kilometers  diameter and very dense material in it. They are different from normal stars. Nearest neutron star away 400 light year from us.           Neutron star formation is very interesting to understand. Here every thing Beyond our imagination. here we see terrible from of gravitational force that even atoms and also the nucleous are destroyed.          Initial state of neutron star  it is normal star ( you want to know about formation of star, visit at  https://myinterestfirst.blogspot.com/2020/06/formation-of-stars-how-are-stars-formed.html ) but its...

      When we think about explosive object,in initial when it exploded, particle in it at high density and also high temperature than after some time when it exploded. As time goes as all matter try to apart from each other and space among them always increases with respect to time. Temperature and density go down with time and expansion rate decrease with time.        Just like this our universe continuously expand from it's birth to till now. So it is possible that in initial state, very high density and high temperature in it. Also the universe start from a dot with very high density and very very high temperature, maybe density and temperature would be infinity.  And in this dot all principal of classical mechanics are destroyed. Called singularity.        After its initial expansion, the universe cooled sufficiently to allow the formation  of subatomic particles,Later atom and as universe expand as elements came...
