Theory of Space -Time curvature by EINSTEIN

 

THIS  THEORY IS GIVEN BY GEATE PHYSICIST ALBERT EINSTEIN 

When he was working on the general theory of relativity  and solving a equation, he realized that massive objects caused a distortion in space -time .

he imagine a large body in the centre of a trampoline the body would press down the fabric , causing it to a  dimple. he suggested  that a marble rolled around the age would spiral inward toward the body  pulled in much the same way that the gravity of planet pulls at rock in space . 

                                    so in this way einstein told that there is a space -time sheet in universe . massive objects prees the sheet down and lighter objects move around the massive object in the circular or ellipitical paths .

for example - in our solar system sun is a massive objects so all the planets move around the sun including our earth

BLACK HOLE -

from this theory the mystery of black hole can be explained as 

 accordingh to einstein massive object distortors the soce time curvature around it  black  hole is an extreme case in the sense that at its singularity the curvature of space time becomes infinite preventing even light to escape from it . 

in the black hole there is a very very strong gravitational field so any thing including electromagnetic radiation(light) or particles can not escape from it .
