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.

[@user-fj2zc9iz5u]

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

[@SkinwalkerFarm]

Thanks Avi

[@WendySwearingen]

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

[@hapaart]

😎Cool Speech.

[@Hayds0]

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

[@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?

[@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.

Harvard is becoming the Donald Trump of Universities.

[@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.

[@user-fj2zc9iz5u]

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.

[@user-fj2zc9iz5u]

@@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?
