Paul Horowitz visited Google's office in Cambridge, MA to discuss the SETI (Search for Extraterrestrial Intelligence) project at Harvard University.
Establishing an electromagnetic communications link across a thousand light-years presents unique technological challenges. In his talk, Prof. Horowitz visits some highlights of the science and technology of SETI -- Do THEY exist? Is communication possible? What is the best way? Is this just completely insane? -- and describes interesting searches his project and others have been doing.
Paul Horowitz is a Research Professor of Physics and of Electrical Engineering at Harvard, and is co-author of The Art of Electronics.
SETI at Harvard was supported in part by grants from NASA, The Planetary Society, and the Bosack/Kruger Charitable Foundation.

Man, this was a phenomenal talk. People talk about how improbable life would be, and I don't think that they really understand the true scale of the Universe and the probability of so many planets that are habitable...as well as how small of a sliver we have been able to view with enough fidelity to descern life. Some very smart people are skeptical and it blows my mind. Even if we agree that multicellular organisms is a one in a billion chance....how can we think we are alone and that hasn't happened elsewhere, or some other combination of cells, probably there is multicellular life that began with and merged multiple times, who's to say there's not tri or quad mitochondrial merging episodes among so many planets? If we are the only intelligent life than I will eat my shoe. What if there are cells that operate in a completely different way, different energy, and/or at different temperatures, different time scales even?

Prof. Horowitz & company have done some amazing technological stuff! Knowing now that there are lots of planets out there & building ever higher resolution devices, it's likely that they will be able to detect signals, if there are any. The problem with there being any is the coincidence requirement - that "they" be sending while we're listening . Allowing for signal travel time! Which is a HUGE factor. Say there is a very advanced civilization a 1000 light years away & they have the ability to detect our strongest radar. So, a 1000 years from now, when those radar signals reach them, they'll know we're here! They immediately send a petawatt laser into space & start talking to us. A 1000 years later, 2000 from now, those laser signals reach us. If we are still looking, the SETI mission will have been accomplished! But will we have the patience to look for 2000 years, or more problematically, will we be able to look? Maybe earth will be in another ice age, or have been hit by an asteroid, or have experienced a nuclear holocaust that leaves a greatly diminished population without the resources to be doing SETI. 2000 years is a long time. Even if one assumes that very advanced civilizations have lifetimes on the order of intra galactic light travel times, it becomes very difficult to get situations where those civilizations' lifetimes overlap enough to communicate.

The answer to the Fermi Paradox. There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to get to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in our Universe.

The Drake Equation is the most flawed thing in existance. It only gives you the CURRENT number of existing ET HOMEWORLDS. It does NOT factor in colonization, exploration or migration. If you applied the drake equation to life on Earth, it'd come up with 1 species in 1 geographical valley in sub-saharan Africa, with NO other intelligent life anywhere on the entire planet. Because it entirely ignores colonization and migration of life. Furthermore it does NOT factor in how many civilizations USED TO EXIST in the past several billion year history of our galaxy. Just looking at Earth itself, the number of lifeforms that existed in the PAST compared to the PRESENT, is an insanely huge exponent which boggles the mind. It is always like this for biological systems, and you MUST factor that in. So even the most pessimistic drake equation result, must be MULTIPLIED by two huge factors. 1. How many colonies AND probes a spacefaring civilization sends out on average, this can be anything from 2 to 1 billion. 2. How many such PREVIOUS civilizations existed in the ancient PAST, because we dont only care about CURRENLY alive aliens, we care about ANY remnants and relics we could find, for example derelict drifting probes, satellites, spaceships or outposts on planetoids. How you can then, after multiplying with both those exponents, getting numbers in the hundreds of thousands or millions (of current or ancient colonies or probes by ancient civilizations), say that we are the only thing in the galaxy or even universe, is utter intellectual bankrupsy.

At near light speed that star would be 6 years travel; space time? Im not running any numbers, but I don’t think you know how fast the fastest is… I think…c… the best tech is always just out of view. Perhaps speed has nothing to do with getting to the stars anyway? Maybe Light travel is light travel? I think you are making category error- contacting extraterrestrial life does not require travel between stars: it could even be in this solar system, there could be other ways to travel. Also, boy not to be rude, but you know what else was fantasy? Everything in Star Trek when it came out: you know what isn’t now? Everything but the transporter and warp drive (human tech I mean) we have the pads, the computer, the tricorder, communicator, even replicator.. sort of. (although I wouldn’t 3d print food, lol) the means by which I communicate this has all these abilities alone, save the last. I would not be surprised if it managed the other two in the future. Time is long and we are brief Jim. However, love long and prosper, if you can. *disclaimer*I do not claim truth or belief in any comment I make with regard to this topic, as this would be insane.

@irisiridium5157 2 жыл бұрын

Interesting question. I thought they just did, lol🖖🏻 Type? Maybe they do have stuff to say, and it’s been done/ as he said: ‘if we make contact it won’t be the first time’- does a single commenter remember him saying these things? Signals? Would we know what to look for, you ask? No. we would not. Or would we… Maybe they did though, and the ‘what’ was/could be (read to end*) Information on how to rule the world? Perhaps seti only stagnates for deceptions sake: that galactic community (he also refers to this in jest) could exist and perhaps enjoy entertainment from the rest of this civilization while a few enjoyed a position of advantage??* It is also just possible that the galactic community could be laughing (while still playing hide and seek) because we make such efforts at this topic when the answer is totally easy and low tech when all one needed to do is use their brain? *By which I mean try directing ur thoughts into space? (like they haven’t tried that already in desperation). What? Everything else is from Star Trek, no? Why not telepathy? Have you tried it? Maybe don’t. Maybe they are already eating us… through our eyes into their eyes. **Lmao. He pretty much said they found ‘them’ whatever that means to you. Pretty strange to bring up a galactic community, disregard the recent extreme advances in tech to focus 3/4 on old (our?) tech, and manage to avoid sharing actual data only briefly and occasionally, but clearly has not been sleeping all this time.js Gotta be crazy cray cray from eradani fortay to hear see sense and think about these things too hard, eh? *disclaimer* I’m only referencing the things he mentioned here: I’m not ascribing to any particular set of beliefs from any comment I make. Forgive the troll-like breakdowns, I digress, he said nothing (found nothing 😉) but also, perhaps; much more than humans can handle right now anyway, so you heard nothings.*disclaimer*
