Shape of our Universe

Scientist have done research about universe with different scientific research and found that it is about 13 to 15 billion year before. About the origin of universe different scientists have given their different theory hypothetically but most of the scientists believe in ‘Big Bang’ theory and it is believe that it is very near to the truth. According to the ‘Big Bang’ theory this all elements, planets, asteroids, comets, satellite, stars, galaxy etc were a same mass in compressed order. When all their compressed elements & energy are blasted and whole universe were created. In accordance to scientist with that period our universe is going on expanding and it is still in progress. In the hypothesis of some scientist our universe will expand to some extend to its boundary and it will again begins to contract and again it will be the same as it was before. Scientists called this phenomenon of universe as ‘Big Crunch’. This name was kept with the theory of ‘Big Bang’ with just opposite name “the ganabcrib”. But some other scientists don’t accept this theory. According to them this phenomenon of expanding goes on and on & it will never reverse back.
There is different theory for the research of universe. Some says universe will expand but up to some extend. And according to them every element has its age and they think universe have also its own age. As the star is destroyed and Black hole is formed, once every star, planets, asteroids etc. will get destroyed; even the black hole get destroyed and this universe will be changed into one dark point and it takes such a time that we are not able to convert it into a number. So according to scientist the shape of the universe can’t be determined as it is changed into one of the dark point.
