Exoplanets are worlds that exist outside of our solar system. Do you think we are alone in the universe?

Obviously we are not alone in the Universe.

[@badfiction5928]

Awful waste of infinite space likely to be fooled by nasa

[@premier1guy]

"a waste of space" is a human oriented self-important comment. Scientifically, it took having the whole universe in size and time to have earth and intelligent life here to be possible. It takes three generations of stars to get enough heavy elements for life to have what it needs, and for our sun to be the way it is. It takes the exact matter density of the universe to have stars be right, as in not all neutron stars/black holes or no stars at all. So, say we were either by accident or by purpose (designer?) to be the only planet with intelligent life -- it would still take the whole universe as it is for it to happen. Still loved the movie, though -- creative and fun. But, new discoveries, not in having a bunch of planets out there, but in astrophysics is showing that it is mathematically increasingly harder for life to have a chance to start anywhere but here. The "follow the water" idea is nice, but so incomplete in that it takes NINE habitable zones, not just one. Besides water is the most plentiful molecule in the universe (other than H2 and H3). The universe is a "wet" place, and yet we can't find a really good candidate planet, yet.

[@snflwrchan8019]

I've always wondered that what if there is life in planets completely different from ours. Because since it's a different world, the way organisms sustain life there would be different. Like for example there's a planet like Uranus out there, it might be 100% impossible for organisms on earth to live there but the planet might be sustaining life in its own way. Like if we breathe oxygen, life there breathe methane. But that is what's normal for them. Just like how life here on earth adapts to its environment, it might be the same there. It's just that how they live life is way way different from how every organism live life here on earth.

[@rochavarrias]

Interesting observation. You may be interested in looking up an online book called Life in the Universe by Marshall Vian Summers

[@xinkixho97]

Yeah thats possible

[@deepspace5121]

imagine if there are other civilizations out there, wondering too if aliens (us) exist. I can't wait to know other life forms exist outside the solar system

[@Goldman200]

They probably exist, I don't think we're unique. But at the same time I don't think we'll ever get to interact with them.

[@deepspace5121]

humans are intelligent. I think they are developing laser to reach the furthest planets to know the alien existence something like that

I know 12 legends from exoplanet

[@jjareu9354]

When the skies and the grounds were one, the legends, through their twelve forces, nurtured the tree of life. An eye of red force created the evil which coveted the heart of tree of life, and the heart slowly grew dry. To tend and embrace the heart of tree of life, the legends hereby divide the tree in half and hide each side. Hence, time is over-turned and space turns askew. The twelve forces divide into two and create two suns that look alike into two worlds that seem alike. The legends travel apart. The legends shall now see the same sky but shall stand on different grounds, shall stand on the same ground but shall see different skies. The day the grounds be kept a single file before one sky in two worlds that seem alike, the legends will greet each other. The day the red force is purified, the twelve forces will reunite into one perfect root, a new world shall open up.

[@topsecret1837]

Frankly there might be already, in the case that we could attempt interstellar travel with FTL vehicles to get to them within a reasonable span of our perceivable lives, like 2-5 years. In that case people who would’ve left this planet by 2040 and as far as we don’t go extinct would have arrived by this time (by that I mean reversing time by a significant multiplier) in another reality and had set up base on an exoplanet exceeding 20ly away.
