Is There Life On Other Planets? | Universe | Earth Science

When William J Borucki joined NASA Ames in the 60s, we only knew about the planets in our solar system. Now, we’re aware of 600 billion. Could there be life out there, and does it look like us?

If there's one question I want to have answered in my lifetime (im 27 now) it's '"are we alone?" That's the only thing I really, really want to know before I die. It would be such a crazy paradigm shift, a complete new chapter in the history of mankind, even bigger than the Copernican revolution IMO.

[@TurinTuramber]

In the widest prospective of time and space, intelligent species of life come and go like sparks on a bonfire. You have to factor in the sheer vastness of space and time, so I think we might not be alone but we are definitely marooned.

[@Ahmed-Benazzi]

Well I have the answer bro we are not alone in this life and the reason we have not found Aliens is that they are really really really far away and I know this thanks to the prophet of god Mohammed which he was the most trustworthy human ever that even god trust him with his revalation and was immune to making mistakes.

[@TurinTuramber]

@@Ahmed-Benazzi You are challenging the very definition of what it means to 'know'.

[@Ahmed-Benazzi]

@@TurinTuramber The thing is we as god said are ignorant and weak and in the day of judgement even the prophets say "we dont know nothing" also Im not challenging the definition but I said I know in that sense only because god said in his book Quran that there is another creatures in the sky.

[@TurinTuramber]

@@Ahmed-Benazzi As an atheist, put yourself in my shoes. A stranger from the internet claims to know something to be true because he interpreted something from an old book of obvious fiction and supported his claim by invoking an old invention - a magical sky fairy. You are free to claim whatever you like, that's up to you. However extraordinary claims will always require extraordinary evidence.

The thing is if other technologically advanced beings exist out there and would have the ability to use technology to see the life on Earth just from a spacecraft, they would see the dinosaurs seeing as they're light years away from us. Imagine being an extraterrestrial being that's studying Earth and you discover there's these giant creatures that could most likely kill you if provoked. Yeah no I would steer clear of Earth if I saw that lol Forgive me if this didn't make sense

If there are life forms on other planets there should be trees and animals and even humans on it Or aliens, because if there is life there is evolution the timeline from that planet and ours should match that there is enough time for the organisms to adapt and evolve.

Not all life will happen in the same steps as ours, you forget the fact that if the meteor that erased the dinosaurs DIDNT hit earth, we most likely wouldn’t have been the dominant species on this planet

[@SuperYtc1]

@@TurinTuramber it usually just means life capable of producing radio waves.

[@TurinTuramber]

@@SuperYtc1 That is of course because practically it's the easiest way for us to learn of their existence. Who knows, using radio waves to communicate could be ancient and redundant technology for a truly intelligent and successful lifeform. If humans prosper for another few millennia, it would likely be archaic technology for humans.

[@SuperYtc1]

@@TurinTuramber Regardless it's still a decent way of distinguishing intelligent life from other life. Only 0.0001% of species to live on Earth have got to that technological level so it is significant, even if other life out there is more intelligent than us (extremely likely given how vast space is). "Intelligent life" is vague. "Radio wave producing civilization" is a fair thing to declare ourselves.

[@TurinTuramber]

Like I said, all seems a bit Homo Sapien centric. In reality, broadcasting radio messages across the galaxy to contact other lifeforms is likely as futile as attempting to your TV remote to communicate with the Voyager 2 spacecraft.

[@malcomrichards9055]

The answers are simple. The First possibility-(Answer #1) We are alone and we are the only life in the entire universe/multiverse. (I'm sure this hypothesis makes Bible-thumpers, narcissists who are threatened with the idea that they we are not the only game in town, and people with fragile egos very happy. Your Welcome!!) (Answer #2) We are not alone and there is plenty of intelligent life in the universe, but this intelligence in particular, is no better than human intelligence. Unfortunately, our type of intelligence might be the pinnacle form of intelligence in the entire universe. (That is a scary thought, maybe even worse than the thought of us being alone!!)Thus, just like for humans, interstellar travel is also too "hard" for all other lifeforms as well. Just like with humans they also suffer from corrupt leadership, and just like us they also don't have the collective will to overcome a myriad of personality disorders that stifle advancement and will eventually be their undoing. Furthermore, we have yet to figure out how to travel anywhere close to a decent percentage of the speed of light.(Not that the "powers that be" plan on putting necessary resources towards cracking that code anytime soon.) So what makes anyone think that any other human like intelligent species can pull off what us humans probably never will? (Wishful thinking much? We are talking about humans here! We can't even agree on global warming let alone invest in the long term survival of our species!) (Answer #3) Super-intelligent alien life does exist but they have not visited us yet. Why? Because we are beneath them. If I was a super-intelligent alien I would not visit us either because we are soooo basic. When is the last time you rolled out the red carpet for the flies that infested your outdoor garbage can? From the perspective of advanced life, we humans are just too basic. They have seen our kind all over the universe many times before and they are just not that impressed. (Answer #4) We are not alone, and the universe is teaming with life! Unfortunately that life is nowhere near as intelligent as humans are (Again, a very disturbing thought!!) The vast majority of alien life is probably microbial, or in the best case scenario, no more intelligent than dolphins, apes, crows, dogs, cats, octopus, etc. If this is indeed the case, then that, in my opinion, WOULD BE AWESOME!! Relatively dim-witted space creatures for the win!! This would mean that human-like higher intelligence is soooo freaking rare that we are literally the only beings who have it in the entire universe. (That would be a sad commentary indeed!!) Too bad our incompetent species will never get a chance to travel beyond our solar system and see any of these cool relativity dim-witted space creatures due to our species collective self destructive tendencies. :(

If we strip away all the "might" and "maybe" claims, this man tells us nothing but "there are lotsa stars".

That's quite an assumption with sample size 1.

@@peterherrington3300 Or, perhaps, it is arrogance of the contrarians who believe that we are singularly the only life to exist in the universe? Simple because scientists say that may be false? As mentioned in the video, there is on average 2 planets per star. If only 10% of those planets are HABITABLE that allows for 30,000,000,000 planets that MAY contain life. He never said that there will be life on every single habitable planet, but it allows for life (as we know it) to have the potential to emerge there. I do not know why this is "arrogance". Just because you do not understand the scientific methods to identify these possibilities does not mean it is wrong.
