Have planets formed around other stars the way our solar system formed around the sun?
Yes, we have found over 400 planets that have formed around other stars: http://en.wikipedia.org/wiki/Exoplanet However none of them formed the way our solar system formed, as these newly discovered planetary systems are totally unlike our solar system. This fact strongly supports the following hypothesis: http://en.wikipedia.org/wiki/Rare_earth_… There is a slim chance that life may exist somewhere in a remote part of the universe. Much too far away for us to ever detect. It is highly unlikely. There are enough species here on earth to study, and they have ALL been proven to exist, and they are all fascinating. There is still much to be learned about them: http://en.wikipedia.org/wiki/Species Mr Hawking was paid to read a script. You can safely ignore what he said. Cheers!
