What if ET is out there?: Seth Shostak at TEDxSanJoseCA

Dr. Seth Shostak participates in the search for extraterrestrial life at the SETI Institute. He heads up the International Academy of Astronautics' SETI Committee, and hosts a weekly radio show, "Big Picture Science". Shostak has published more than 400 popular articles on science, and his most recent book is Confessions of an Alien Hunter, A Scientist's Search for Extraterrestrial Life (National Geographic). Shostak is also an accomplished photographer. His photos have been featured on the cover of Time magazine.

In the spirit of ideas worth spreading, TEDx is a program of local, self organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, Where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.

[@justinbosker7762]

I for one applaud SETI for continuing their search even with all the skeptics ridiculing them. Just because we have been searching for 60 years means absolutely nothing! The problem is people are so wrapped up in themselves that they don't think of generations ahead of them. I, for one, think it's well worth the hard work even if it doesn't happen in my lifetime. My descendants thousands of years from now will appreciate the work we put in and embraced.

[@mycount64]

It is a given that life is elsewhere that they were transmitting signals at just the right time for us to detect them here is very very very low probability. Other than getting the feather for discovering it, it will be of little material value I suspect.

[@icarus6424]

Any type 3 civilisations out there know we are here. Type 3 civilisations will have all the technological capabilities general relativity will allow. These are civilisations that are technologically advanced by at least 1 million years. The most pressing concern for a type 3 civilisation is establishing a communication network that will allow them overcome the distance problem the universe presents. This communication system is for their benefit not ours. If a type 3 civilisation exists it can be inferred our planet and species have already been surveyed simply because they have the technology to do so. They know we are here and they are not interested in contacting us. Even if we manage to detect them they will simply not care. They know what we are simply because they have the technology to know. If you were a leader of a type 3 civilisation, would you donate technology to a species that point nuclear weapons at each other? There will be no short circuiting history. The journey to type 3 is our journey and its being monitored by a type 3 civilisation as I type these words.SETI are in the buisness of measurement not investigation. Mr Shostak needs to look closer to home.

The give away for our planet being here and having life on it, would be detected by aliens in the same way we are going about looking for alien worlds that support life. The give away would be the spectral analysis of the earths atmosphere where large amounts of oxygen would immediately indicate life. And there's almost no chance that our planet hasn't been surveyed.

Great, very interesting video. Thanks.

[@seanogreen8558]

They're so advanced we honestly couldn't comprehend the truth

[@Dylz0]

His point is that any ET that we would get a signal from would have to be as advanced or more advanced than we are for us because if they weren't they wouldn't have built technology to communicate via radio waves. He's not saying that less advanced ET don't exist, only that we wouldn't know they were there, at least with this type of exploration.

[@petterp4679]

Dylz0 what says they wouldn't be extinct? Considering the time it would take for a radio signal to reach, that seems... feasible, granted we don't know the average lifespan of a radio capable civilisation

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.

[@mohnkhan]

Good speaker, like the ant anecdote . The ant queue vs the few ones who are explorers but make or break the ant colony

[@polka23dot]

mooliki01 wrote: "...you make random assumptions as to the technological capabilities of such life." I make only one assumption: their civilization is at least 100 million years older than ours. It means that they transform all raw materials into something useful. As their space civilization expands, they transform the universe into something much more organized than random heaps of raw materials, something as organized and as conspicuous as our cities.

[@patriciodasilva7902]

Seti is based on a flawed premise, which is that extraterrestrials are using radio-frequency to communicate. Seems to me that advanced extraterrestrial beings would have evolved to a level where they can communicate across Interstellar space which would disallow RF transmission because of the slowness of the speed of light. What is more logical to me that these Advanced beings would have evolved to a level whereby they communicate via telepathy which the large SETI antenna arrays they're using cannot detect. Even if aliens were using RF to communicate there's the issue of synchronicity.

[@patriciodasilva7902]

@Baltimorean Adventures raw unedited content and that is assuming the life on that planet is synchronous with ours. If their Planet came and went 12 billion years ago the signals might have passed through us already long before we're able to detect them. Synchronicity greatly reduces the odds

I'm glad you brought this up because that's another thing about the video I don't understand. Why would anyone think that radio waves are a technology that a) anyone thinks an alien civilization would be broadcasting into space and b) that anyone thinks aliens would be even able to detect the radio signals we have been putting into space. First of all, the period of time we will have been putting radio signals into space is almost over. And those signals themselves are very weak.

Everything we need is a common goal. It is not the intelligence of a species which differs from the others. One can very well kill one another by being intelligent. We only need to have an idea, a common dream. All we have to do is move forward collectively. For now, all we are doing is seeing in the short term, according to territories (countries) and their resources. We could have the universe, by our intelligence, but we prefer freedom, comfort ,security(in one way) and individual power.

[@DamienLepage]

You may be thinking about radio waves such as those used by AM/FM radio stations but we broadcast a lot more than this. And it gets only bigger. Obvious examples are mobile phones, GPS but also all the electromagnetic radiations produced by all kinds of electronics. Maybe we can imagine an advanced civilisation which wouldn't produce any artificial radiations but the likelihood that we're not the only one to produce those is pretty high in my opinion.

They don't have to be more advanced. In fact most alien life is microbial. However, if we detect an alien broadcast signal, the statistical probability(given the age of the Milky Way galaxy) would be that they are a much older civilization provided that they have been broadcasting throughout their existence. However, this is a questionable premise given our planet will go radio broadcast quiet in the next 100 years. This would suggest that the radio broadcasting alien civilization (cont'd)

An intriguing issue is the capacity to travel such huge distances through space. Beyond our solar system the nearest star is about 280,000 equivalent distances from Earth to Sun, i.e., the nearest star is about 26 trillion miles from Earth. At the speed of light it takes just less than 10 minutes to reach the sun but 4.3 years to get to the nearest star. Obviously, if advanced life has been hovering in our neighborhood, then they figured out how to circumvent the speed of light barrier.

[@MumblingMickey]

I think you are ignoring the fact humans are predators. That's given us a serious advantage in that predators are generally smarter. But the downside of being a predator is that you are totally dependent on resources provided on the food chain below you. If anything happens to upset the delicate order of that chain, then everything above that link goes extinct. Now fair enough, if you think all links in the chain below humanity are perfectly okay, then you have nothing to worry about.

[@DamienLepage]

We may be more unnoticed than you think. Most exoplanets discovered so far are more than 100 light-years away from us. It means the only signals they can currently see coming from Earth are from 1900 or before, certainly not a lot of interesting signals for them to study. So, if they're really more advanced than us, it's actually very likely that we find them before they find us.

Exactly, some people don't understand how silly we are scanning for radio waves, we might as well be scanning the skies for alien carrier pigeons with binoculars, if it is a radio wave it will be from a long ago (billions of years dead civilization) if the signal would even reach us after that distance, supposed smart people don't even realize how stupid they are even looking in this manner, at least you understand callum, one in ten thousand might even begin to grasp how complex this issue is. I don't scan for wifi networks by looking for smoke signals, and that's not even a close comparison of how lame our attempt really is using radio waves (light).

[@yaosio]

Radio signals can only travel at the speed of light so any signal we can receive could be thousands of years old if the signal survives. If faster than light communication is possible there would be a small period of time where a civilization uses radio and FTL communication, with FTL communication eventually replacing radio when the technology becomes cheap enough to implement everywhere. We most likely have a small window to catch radio signals.

[@patriciodasilva7902]
