Alien Life: Will We Know It When We See It?

  • Published on: 17 July 2014
  • What are scientists looking for when searching for alien life? A lot, it turns out: the search for extraterrestrials requires the help from astronomers, planetary scientists, chemists, computer scientists, and geneticists, just to name a few. But are we barking up the wrong carbon-based tree? Could alien life develop in ways we haven't dreamed of here on Earth? Hear Paul Davies, Sara Seager, Jack Szostak, and other experts give updates on the search for life outside our planet in "Alien Life: Will We Know It When We See It?" part of the Big Ideas series at the 2014 World Science Festival.

    This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

    My question is, let's say they detected microbial life on a planet 30 light years away .And 30 light years is the closest after searching for many years. Then what ? We can never go there to verify there is life so like like I said, then what ?All this money tax payers are partially footing the bill just so scientists can play. If there is NOTHING gained, and most citizens cannot benefit from, WHO CARES ! Again, if they discover Simple life,then what ? Nothing ! That's the end of story . I don't think a warp bubble , or creating a worm hole is in our future. A solar sail is very questionable. We will never ever be able to visit a planet light years away so once again, simple is detected, End of story. There is nothing we can do beyond that. To me,this is a HUGE waste of money.I'd rather spend money on things that benefit EVERYONE. Like working on diverting space rocks with Earths name on it

    Humans are aliens to humans. All we know how to is destroy one another, create clever lies to hide the truth and pretend nothing ever happened. Instead of worrying about another galaxy, why not fix the mess we made of this planet?

    It's very frustrating that no one will believe me but, I swear, a few weeks ago I saw a UFO turn into an airplane - I think this is how they've been hiding from us.

    if man so called evolved in 65 million years after the Dinos died then why wouldn't intelligent life have developed during the 265 million years the Dinos were here? I say it did... the ufos we see today are not from other galaxies they are right here from good old earth.... I also believe they colonized Mars and the ancient planet Rahab, which is now the asteroid belt. It along with Mars was destroyed in a War amongst themselves. Both factions of the war are still here in the solar system. One is benevolent the other is not. A good guys bad guys thing. The good guys are preventing the bad guys from interfering with us and the bad guys have been playing hide and seek with the good guys, as aerial battles between UFO's have been observed by many people over the course of our history. Man has come to know these life forms as Angels(good guys) and Demons(bad guys). It is my belief that the bad guys are manipulating mankind in order to advance us and make us capable to help them as they know that a final showdown is coming and they need our help, so when the good guys show up we will think they are here to destroy us and we will attack them, at this point the bad guys will join in to try to over come them... The bible says 1/3 of the angels rebelled and 2/3 remained loyal to their leader The 1/3 are the demons. They are out numbered so need mans weapons' to help even the odds for them. ... if life developed in the universe it had to start some where and there had to be a first one, and place.... earth is that first time and some place that it happened.....

    None of us have a clue. But if alien life exists whatever form it is, would debunk religions especially the Abrahamic religions once and for all. Even finding microbial life or evidence would put an end to this Sky Daddy insanity.

    Spacewalk. Have you ever sat somewhere and just thought? Your mind wanders to the people you meet the places you travelled to at some point maybe to a country you have never been to before? Then you zoom out from what youre used to. You see this blue floating ball of matter in front of you, fly through space and time, see how it's bent around, feel how you are part of this thing called earth, see the oceans, mountains, deserts, countries. You see night and day, rivers and tides flowing. You rediscover how everything is connected to everything, how you yourself and every piece of your being from birth to death, are connected to the soil your body emerged from. Stars collided with the force of a billion suns planets formed Gamma rays burned down entire civilizations way before a bone flute was crafted in a cave thousands of years ago A man was nailed to a wooden cross andeverything from the romans marching over Europe to the discovery of America to the great wars... It all led up to a man walking on the moon. What is to come in the future?What is out there beyond our reach?this is the gaze into black and far chaos. the vast unknown stares back at you. ridiculing you in cosmical loudness. The echoes of its laughter, formed out of millions of exploding suns giving birth to new life in eonds of time... it is silent to my deaf ears dark to my blind eyes. numb to my cold skin. I thought I knew something, but I know nothingIf you read this to the end thank you <3I wanted to capture this feeling so I wrote a song about itit's on my channel if you want to check it out :)Have a great day and never stop stargazing!

    I would offer my services as a translator, but you must help me first: What is the difference between an "astronomer" and and "astonomer" like Mr. Sasselov? (7:41)Please don't say "just one r". I need a Google account you need the missing r, I guess. Then you can pay me for translating correctly (about $ 40 each minute of video), first minute free.

    Uhmm, the fact that only Americans are allowed to be the Planetary Protection Officer in charge of not spreading diseases to other planets is comedically ironic considering we are the best country in the world at spreading diseases.
