Harvard Professor Avi Loeb on Signs of Life Beyond Earth

[@alanwhiplington5504]

He's basically right. The universe is so large, and so old, and the chemistry of life is literally spread between the stars - of course there is life out there, and intelligent life too.

[@kevinfisher466]

you dont know anything though. you cant say how old it is.

[@Roop1962]

@alanwhiplington5504 I agree with you that there is bound to be life, even intelligent life, somewhere out there but it is uncertain if we shall ever meet them. Besides, if the alien life forms happen to be technologically superior to us, which is very likely, the results may not be felicitous for us as a species.

"Analyze the skies over São Miguel Island in the Azores, as there have been past years when I saw some UAPs even in the uninhabited part of the island, and sometimes I still continue to see them."

[@WendySwearingen]

So interesting. Sound could be improved--very echo-y.

[@Supersphere455]

Avi Loeb has the most unique mind, the man is pure genius.

[@jackcrane7853]

Nonsense

[@cspicer4611]

Thank you for sharing your intellectual gift with us all. 🙏🏼

[@chrystele1988]

Oh, thank you for this video, and this knowledgeable sharing… Thank you for everyone 🙏🌍❤️‍🔥

[@ChaLy-r4d]

We're waiting for a description and analysis of the evidence you collected from your sailing trip.

[@Hayds帝]

Is the betz sphere potentially related to the material you found?? Similar looking just different size

[@davecorry7723]

Galadrial jumping off the boat and then planning on swimming 3000 miles in a dress with no food,water or sleep then accidentally bumping into sauron half way across is so absolutely ridiculous that i can't believe someone actually signed off on it and was like yeah that will work

[@SkinwalkerFarm]

Thanks Avi

[@livrowland171]

Good talk but not sure the point of this format, done in an echoey observatory room, with the image only taking up half the screen. It's not really working for me to have half the screen just for the purpose of showing random graphics illustrating words he mentions.

[@etbedtalksAOH]

Avi, If someone has been here for 80 years without disclosing anything, then they are not a visitor.

[@stevedwyer8333]

If it took them a thousand years to get here, 80 years could be considered to be a visit.

[@sentientflower7891]

​@@stevedwyer8333the minimum interstellar travel time is measured in millions of years.

[@azzzzr]

@@stevedwyer8333 if humans fly for thousands of years and found a beautiful and resourceful planet there with technologically and mentally undeveloped beings there, would we just come back without taking advantage of that planet? Especially if the resources in our planets were heavily depleted because of our technological advancement?

[@stevedwyer8333]

​@sentientflower7891 I almost said, "If it takes them thousands or millions of years to get here, their time here could be considered a visit even if they stayed here for for a long time in human terms." But even the New Horizons spacecraft could get to Alpha Centauri in 80,000 years, so the minimum time for interstellar travel for an advanced civilization would certainly be less than 1,000 years. But yes, some trips could take millions of years.

[@sentientflower7891]

@@stevedwyer8333 New Horizon cannot get to Alpha Centaur in 80,000 years. That's not how visiting another star system works. If you want to attain orbit around Alpha Centauri you can get there in a thousand years but you will have to slow down in order to attain orbit around the star and that maneuver alone will take 100,000 years.

[@hapaart]

😎Cool Speech.

[@Indygo9]

NASA/JPL already know about Martians. Curiosity sol 1065 rim of Gale crater Mars has parts blacked out. .... but they missed a lot.👍🏼

[@rodfaragini7110]

Listen to everything Avi speaks about. His take makes one think

[@mrtienphysics666]

So aliens have visited earth?

[@sentientflower7891]

Avi Loeb knows, he is an extraterrestrial. Technically an illegal alien though the boundary he crossed was the stratosphere.

[@rezazulhairy4170]

Human is in dimension 3. And alien is in dimension 4 above. They have high not just in technology but also high in spirituality.

[@azzzzr]

West is more technologically advanced than East. Is West more spiritual?

[@la7079]

Technology doesn’t mean higher spirituality

[@azzzzr]

@@la7079 exactly! If technology means more spiritual, then the invading colonialists must have been more spiritual than the native Americans and Indians.

[@cbk666]

Harvard magazine can't provide a proper mic??????

[@ChaLy-r4d]

What? What? Where is the explanation of his sailing trip and evidence analysis? This huckster is shameless.

[@mwazra6625]

It takes time to analyze rigorously something that contains such noisy data. I am waiting for the analysis to come to make my mind. What makes you so skeptical when we know so little about what he is talking about? He is saying something that could be and probability is on his side.

[@ChaLy-r4d]

@@mwazra6625 you sound like a Christian ignoring everything that disproves what you want to believe in. The church of interdimensional Avi.

[@ignaciourena5692]

Professor Avi Loeb I really don't understand what kind of evidence you need ...

[@realsydney7327]

Nope. Wrong. No life out there.

[@Cheddarturd]

Hahahahahahahahaha

[@RobertStek]

Thanks for that well-informed, logical, and scientific refutation of Loeb's informed speculation.

[@realsydney7327]

@@RobertStekThere's no evidence of life external to Earth.

[@RobertStek]

@@realsydney7327 Your first remark was a fallacious appeal to ignorance. You conclude that life external to Earth is not possible because it hasn't been proven conclusively true. Loeb's arguments are largely probabilistic based on possible interpretations of accepted evidence. That doesn't make them true, but he is a scientist hypothesizing and looking for additional evidence. Your second response is also fallacious reasoning. You cannot conclude that absence of evidence is evidence of absence.

[@mwazra6625]

Maybe there is, maybe there isn't. If there isn't the burden of proof is on your side - what is your evidence?

[@faizanrana2998]

AHAAAHAHAAAAAAAA AVI LOEB

[@kevinfisher466]

stop posting old videos Goofs

[@VaraLaFey]

Hang on. What do you mean we'll never know any more about Oumuamua? I thought Breakthrough Starshot was at least halfway planning a future mission to it.

[@friendlyone2706]

It's still not fast enough to catch up.

[@VaraLaFey]

@@friendlyone2706I'm pretty sure the people in the project say it will (if the project ever deploys). On what grounds do you contradict them?

[@friendlyone2706]

@@VaraLaFey The amount of head start and the speeds necessary to catch up greatly exceed anything we have currently done or even have on the drawing board, and would require nuclear power. I fully support nuclear power in space, but it has problems (mostly social caused sourcing difficulties, but that's another problem). What it MIGHT be able to do is get in a position to be able to see it, if it's were its last known trajectory indicates it should be. If it's not there -- most likely -- it will probably because of all the known and unknown gravitational influences. We've known since Sir Isaac Newton's time the 3-body problem is insolvable and space is infinitely more complex than a mere 3 bodies. If we can get it in our sights, with our improved optics maybe we will finally at last know what it looks like. The money such an effort would require could be spent sending a bunch of small, programable (hopefully nuclear powered) voyager-type craft to patrol the asteroid belt. The next time an interstellar visitor is seen approaching, the nearest asteroid-patroller would be sent to get close -- perhaps even land on -- the incoming object. If we officially know of 2 interstellar rocks within the first 20 years we have been able to reliably identify and see them, there must be many such. Asteroid patrols have a nearly 100% success probability.
