We all know that Earth and other planets are created by the BigBang. The time is also calculated from the bigbang. So what happened before BigBang and wasn't there time? How was the first living cell form on the earth? Is Time travel to past is possible, then can we go beyond the bigbang?
Are all universe, planets, space rocks were once a single body before? Then how that planet had looked and whether it had living things? All the galaxies are moving away, how far they can go? Can all this be someone's science experiment gone wrong? When will the time end (will time be there even if everything in the universe gets destroyed)?
Where will be our mind and our thinkings, before our birth and after our death? Will it get destroyed or transferred to something new? Do you wish to see how humans in the future looks like? At the time of Earth is going to be destroyed by the nature, do you think the humans are smart to leave the Earth or protect themselves?
