Ever wonder what will happen when our Sun dies killing everything surrounding it and leaving the beautiful intelligent life that resides in this galaxy go extinct? Unless of course we kill each other before the Sun does in a dispute over the name of 'The Creator', in that case we can't blame it on the Sun.
There were so many things tagged as impossible a century ago, such as man on moon. There are many we still tag as impossible such as invisibility, space travel, teletransportation. Ironically the word impossible itself says i am possible ;-).
The famous theoretical physicist Michio Kaku talks about these impossible things in his book 'Physics of the impossible' and how far scientists are in cracking the code.
Do you think a billion years from now humans will be hopping from planet to planet, populating (and polluting) everywhere around? One can only wonder or then read what these brilliant minds have to say!
I liked the book and am planning to read all books by Kaku. Will keep you posted ;-)
