Could Exoplanets Be Mankind's Savior? | Thousands Of New Worlds | Spark

Are we alone in the universe? This question has been one of the greatest mysteries of all time. 20 years ago, individual scientists began to challenge traditional planetary science as they set off to seek, observe and reveal the existence of unknown worlds: EXOPLANETS. The film recounts the epic journey of these astrophysicists, who turned our knowledge of the universe upside down, in their quest for extraterrestrial life.

Astronomers estimate there are about a trillion trillion stars in the observable universe. Each star is the center of a solar system usually with a number of planets and some planets probably have moons. If it is extremely unusual for a planet to have life, say, one in a million solar systems have a planet with life, there would be a million trillion planets with life. If it is extremely unusual for a planet with life to have intelligent life, say, one in a million that would leave a trillion planets with intelligent life in the observable universe.

After the challenge of crossing vast distances, I think that the biggest obstacle to human colonization of exoplanets will be gravity.

[@christopherstmarin]

What if life on other planets don’t need what we do? Water, oxygen etc. we have living things on this planet that exist without

[@Major_FaimOfficial]

I pondered something similar. We think of life as carbon based forms. I imagine there is other non carbon based life forms out there as well as more carbon based.

[@Isawwhatyoudid]

there is no life form on this planet that survives without water. In rare cases some single celled organisms and maybe water bears (a phylum of *extremely* small invertebrates) may go dormant in dry conditions but to continue their life cycle they need water.

I don't know why everyone talks about going to these planets in the comments of videos like this. The point of discovering these worlds is to find alien life, not to find a new home. It's completely impossible for us to travel between solar systems and even if we could go the speed of light, most of these planets would still take 5 human lifespans to reach.

[@peterclark6290]

The Logic of this Universe is universal. As with the development of the human genome, happenstance mutations and natural selection (including opportunity, political/group decisions, etc. adjustments) lead inexorably to higher forms of life. The time available is equal, shared, and regular. I suspect we are looking for the opposable thumb being grafted onto a herbivore to see the alpha/sigma creature/society with the most potential. Unfortunately carnivores have a default setting for life-altering violence hence our embarrassingly slow progress. Without Gods we would have had moon-sized telescopes peering successfully beyond the 'cell wall' of this big bang event millennia ago.

[@mike9347]

Yeah, like your argument is based on any form of actual proven theory at all. Science isn't about God or Evolution mate. Science is Science.

[@peterclark6290]

@@mike9347 Read it again, this time without prejudice. I am a highly confident Atheist. Evolution is a Science.

[@johanhuman4382]

Evolution is not science. As atheism, it is based on religion. A lot of evolution is based on conjecture. You believe there was some kind of soup on the earth and by some miracle lightning supplied the energy for life to occur from the soup, etc. but no way to prove it.

[@mike9347]

@@johanhuman4382 Agreed. Like Religion, it tends to take a lot of faith to believe in it rather then solid scientific arguments. It's just the religion of today. I'm sure there will be another one along in a hundred years :)

[@peterclark6290]

@@johanhuman4382 Atheism requires no beliefs whatsoever. We merely reject one more God explanation than believers do. But we're still human. In the absence of any plausible alternative the remote possibility of lightning acting on primordial soup remains a contender. Only the Scientific Method can reveal the truth, hence Evolution is a part of the Sciences. Belief is a radioactive brick wall, created by a flawed or conflicted mind. E.g. humans pattern match (pareidolia), see violence as a primary problem-solver, take 25 years to develop a useful mind, etc. We may not be Nature's most refined development. The persistence of belief underscores that last sentence.

[@boltaurelius376]

Obviously, our is planet the only we can draw an idea of what it takes a species to become a space faring society. From the moment of abiogenesis to now, all innovation has been guided by competition or desperation. From evolution, harnessing fire (to cook meat), the spears used to kill all the way to the V2 rockets and the space race. Perhaps we are one of the first species that develops the technology to wipe ourselves out but doesnt before becoming multi planetary. Perhaps were the first species that doesnt stop global warming thus preventing the ice age that wipes other, more "sensible" species out. Maybe all species keep quiet as theres a martial species that stalks from solar system to solar system look for a hard fight because that's their religion or something.
