Are we alone?

Though not in my typical realm of posting (perhaps I’m too politically centric with this blog), I just caught wind of news that the first potentially habitable planet that is similar in size and conditions to earth has been discovered some 20 light years away.

It is an incredible discovery as it points to the potential for life on other planets given that it hosts similar conditions to those on earth which helped make life a possibility here. 

At 20 light years away it might be by the end of my life that we get our first concrete answer to the question of other life out there, but it certainly would be an incredible thing to live to see.

Second: Odds of life on that one perfect planet, debateable, but reasonable. Third: that said life is intelligent Four: window of intelligent life, there’s been life on earth for millions of… Read more »
