“Conceptual Artwork Of Kepler 20f Earth Like Planet” by Victor Habbick via freedigitalphotos.net
One of eight new planets spied in distant solar systems has been given the title of "most Earth-like alien world" by astronomers. This made me wonder if, in an infinite universe, there could be intelligent life on other planets. Do you think there is and we just haven't found it yet?
I think there must be some other intelligent life besides that found on Earth. There are so many planets that we know about and probably even more that we don't know about - how can we possibly be the only inhabited planet?
The light from stars we see has taken thousands of years to reach us, and many of them no longer exist even though we can still see them. It could take thousands, if not millions, of years for a signal to reach from one habitable planet to another and when it did there might no longer be life there. It's not like you can just leave a message when you're working with a timescale like that.
