I ever wondered(P.P.F.,past,present,future)what will happen to Earth one day?what was life like in the past?will there be a ending route in the universe?will that be "other people"?Basically what I know about this is about 0.001% only when compared to the whole universe.Why did dinosaur extinct in mass?(Global Warming?)There is too much things to learn in this world...just too much......Will Earth ever survive......? We are indeed very lonely in space.There are just so much things happening such as natural disasters and so on......
