• That's really an impossible question to answer. It may, it may not. Maybe someday we will find out but it's just not knowable at this time.
• It has been determined mathematically that it is more probable than not.
• Of course. It's simply highly and extremely improbable that with the vastness of the universe we're the only life supporting planet.
• How could there not be? I mean if our systems revolves around the sun which is really just a star then there has to be other systems surrounding other stars that we see in the sky, and out of all those places, there has to be other planets that are habitable. It would almost be ridiculous to deny it.
• Yes, but it may not be life as we know it. +5
• yes,there are so many planets one must hold life forms.+5
• I respectfully disagree with all of you. Roughly using scientific estimates known today, 1 in every 1 billion (that's 1/1,000,000,000) planets in the universe has an Earth-like atmosphere. This number is used as an estimate and can not be verified however.What is the probability of life beginning on Earth by chance? If we estimate that there was a 1 in 10 billion chance (that's 1/10,000,000,000) that life would begin on Earth and then apply that statistic to the universe.In simple probability studies you simply multiply the two probabilities together to see what you get. In this case 1/1,000,000,000 x 1/10,000,000,000 =1/10,000,000,000,000,000,000. This is the probability (according to our hypothetical calculations) that life will exist somewhere else in the galaxy. That is the same as saying there is a .0000000000000000001% chance of life existing elsewhere in the galaxy. Secondly there is no proof of life existing anywhere with our telescopes, studies and space exploration programs.
• You cal this a life?
• Probably, but not necessarily AS WE KNOW IT.
• It's a near certainty. It may even exist in our own solar system (beyond Earth). Mars, Europa, and Titan are all possible sites.
• yes it has to
• I'd be willing to go so far as to say DEFINITELY! ABSOLUTELY! Will we ever see it as a species? Hell no.
• Yes, I really do. One day, they will come and visit the earth.
• our galaxy... im not so sure. but in another galaxy i think no doubt. of course there is.
• Do you believe in life after love?
• Yes, I really am convinced there is. Here's a video to show what I could be typing, to save myself a ton of time. http://www.youtube.com/watch?v=mcBV-cXVWFw It's a video about the Hubble Deep Field
• It's possible.
• sure I do
