BEGINNING AND BOUNDARY OF UNIVERSE AND TIME

[davie]

Just what is the Big Bang theory of the origin of the universe? One scientist summed it up succinctly by saying: "The explosion from zero volume at zero time of a corpuscle of energy equivalent to the mass and radiation that now constitute the Universe."(2)

some of my concerns:
If milky way galaxy is one such galaxy in the never ending universe, there could be infinite number of such galaxies that exist in the infinite space. Who is responsible for creating all these space? Are these concepts too difficult for humans to understand?


And if there are many Universes, then are there any Universe in which the physical laws like laws of mechanics etc does not hold true? If yes then evolution process said by scientists would be governed by the propriety phenomenon of that particular universe??? I am quite clear that life similar to earth exists in infinite number of planets.
