An alternative to earth?

It’s possible that astronomers have found a solar system not unlike ours that might harbor a planet not unlike Earth where life that survives here could also thrive.   It is 41 light years away.  It’s currently called “55 Cancri,” but if a parallel Earth-planet is found, it is sure to be given a more memorable christening.  There is also the solar system “HD 154345” which might provide a hospitable home to people like us, if we can develop the means of travelling 59 light years away.

Astonomers’ ability to see more detail deeper into the universe means that more and more celestial bodies, stars and planets, are being found.  Whether we will live long enough to figure out how we might ever be able to reach them is a significant unsolved problem at this point.  Light travels about 11 million miles a minute, making a light year, the distance light travels in a year, a hefty trip.  Even getting to Mars will take 2-3 years at current rates of travel, and of course, people will want to get back to Earth, at least until supermarkets and the internet are established on Mars.

Personally, I think we’d better figure out how to survive on planet Earth all by ourselves for a little while longer.
