"It is important for the human race to spread out into space for the survival of the species," -- Stephen HawkingI'm curious to see how inspired Stephen Hawking became after his zero-gravity flight last Thursday. I can't imagine what he'd be thinking and contriving after being free from his wheelchair for only 45 seconds of free fall. I am indeed happy that he could experience such a feeling--to add that much more joy to his life. Let's just hope that he didn't munch on too big of a breakfast :-).
And I agree with Dr. Hawking and periodically delve on the same scenario (actually, I think about it quite often): 1 to 7 billion years from now, our Earth will indeed die and we humans MUST find somewhere else to live beyond Earth if we are to continue to exist. And for that to happen, I can't help but think that faster-than-light travel would need to be possible (would HAVE to be possible!), given that the Andromeda Galaxy is our closest galaxy neighbor at 2 million light years away or otherwise a closer solar system in our own Milky Way Galaxy.
(I always remember the incredible opening scene of the movie Contact, staring Jody Foster, as it gives an amazing perspective of how huge space is.)
The possibilities of how we would exist in the far future are infinite. How fun it is to take just one and imagine life then.
