NASA announced last week that they have discovered more than 700 new planets. Some of them are very Earth-like, with water and atmospheres that sustain life.
Why is this so exciting?
In my opinion, it is only a matter of time before this planet runs out of resources. The stuff of science fiction - leaving a home planet in search of others - is actually coming true right before our eyes. There are plans to send people to Mars in the near future to colonize it, and with the discovery of other planets that can sustain life, it means that perhaps our grandchildren or their grandchildren will someday be able to travel to another world as easily as we hop a plane and fly around the world.
Is this too far-fetched to believe?
I am reminded of my grandfather's saying every time he thought someone wanted to accomplish the impossible. He'd say, "You can no more do that than send a man to the moon!"
