As we got to know that Einstein stated about that ”cosmological constant” when astronomers told him about the universe i.e the Milky Way galaxy at that time. Now according to multiverse theory it will be possible that the one of the universe may feel the Big Bang and Big Crunch every second in every minute in every hour in every day in every year and simultaneously in every light year. So the first work of ours to develop some new kind of mathematical tools and new kind of physics which will help us to understand about the DARK MATTER and COSMOLOGICAL CONSTANT (DARK ENERGY).
