Yes i love these kind of videos. Puts into perspevtive how ridiculous it is to assume we are the only planet with live on it. Not saying it travels here but assuming we are alone in a universe this big is a bit presumptuous in my opinion.
I don't think we are alone but we may be alone in our now. If we don't find intelligent life within 50 light years of Earth than we are essentially alone. It turns into archeology after 50 light years or so away. Finding life thousands of light years away would be akin to discovering a statue of Cleopatra. We know she existed but we could never communicate with her.
Hmm. Not sure about that line of thinking. The human race is still alive and well. Ancient Egypt is gone but humanity continues. You're assuming the life span of an entire intelligent species. Now, that culture may be gone but chances are the alien species is still kicking.
I was thinking in terms of a human lifespan and even a cultural one. If we find life more than 50 light years away than no one human could communicate. It would take generations. If it is for many generations (1,000 light years away) then who knows if the people around then (2,000 years in the future) will even know we made contact now, sent a reply and are awaiting a response. That doesn't really count as communication if you ask me.
Life is probably common. But complex multi cellular life is different. The size of the universe isn't some overriding factor in complex life being out there. You can make the universe as big as you want but there's only 14 billion years to play with. It took something like 3.5 billion years of earths oceans full of life until it by chance turned multi cellular. That's a notable chunk of the age of universe. Not saying it rules out complex life being out there, but people shouldn't say it's ridiculous to think otherwise considering it took 3.5 billion years here on earth
I recently wrote a column on this very subject:
Good point, i didn't specify multi cellular life and ridiculous may indeed be a overstatement but i did mean complex life, not at our level or above necessarily i would still say the odds are pretty good.
Wouldn't more star systems increase the probability that rare conditions that caused life to form on Earth also happened exactly the same somewhere else in the observable universe?
Pale Blue Dot Quotes Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.
Man I was letting brokeness and depression ruin my day. Thanks for bringing me back to reality
Sometimes this makes people feel smaller. I'm glad it made you feel big. We are part of this Universe and the Universe is a part of us. Much love.
These types of videos will never cease to completely stupefy me.
The rapper Project Pat sampled this music in one of his songs. (Make that azz clap)
This was hilarious to read after reading the next super profound comment up.
this sums it up for me
This video reminds of me a gif I kept seeing in my hot posts homepage, comparing earth to sun and other stars, very similar to this video but in gif form. Can’t find it now but wanted to show some people. Can anyone help me out?
