Are We Alone? When Will Earthlings Find ET? | Dan Werthimer | TEDxSFState
Вставка
- Опубліковано 24 лип 2024
- Berkeley Chief SETI Scientist Dan Werthimer discusses the possibility of intelligent life in the universe and how Earthlings could detect other civilizations. Dan presents the new $100M Breakthrough Listen project, as well as the SETI@home project, which analyzes data from the world's largest radio telescope using desktop computers and cell phones from millions of volunteers.
Dan Werthimer was in the Homebrew Computer Club with Steve Jobs and Steve Wozniak; everyone in the Homebrew Club became ultra-rich except Dan. Dan is currently chief scientist of SETI@home, Breakthrough Listen, and several SETI programs at the University of California, Berkeley. Werthimer also directs the Center for Astronomy Signal Processing and Electronics Research (CASPER), and is associate director of the Berkeley Wireless Research Center (BWRC). Werthimer was an associate professor in the engineering and physics departments of San Francisco State University and a visiting professor at Beijing Normal University, the University of St. Charles in Marseille, and Eotvos University in Budapest.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx
Coming from 2020, I can confirm that the Arecibo telescope has also been zapped by hostile space aliens!
Did the Space Aliens who destroyed Arecibo space telescope use Jewish Space Lasers like famed congressional conspiracy theorist Marjorie Taylor Greene a la QAnon warned? 😂😂😂
@@blazemanize21 lol absolutely
😂😂te quedo cabron👍
What if the aliens we can't find are from the planet we can't find - and our little bug eyed buddies don't want us to find it? 🤔
It's interesting how different people percieve things. Most people have negative comments about this speaker. I liked him. He made a speech (which are often dry) more intetesting by adding some humour. It's very common.
they aren't sceptical people. they think it useless. you know why? because those professors working so hard to communicate/find communication in ET while ET flying object sometimes can be found in the sky. why dont government just hit those ET flying object then investigate the pilot. really easy solution
@@vaxlrstov5856 Oh, they`ve done that. But in all the newer UFO videos I`ve seen, they started zipping back & forth, here and there(so fast), like they`re trying not to get hit.
Chances of ET are so slim the search is a waste of time. Nice to hear the software has other, useful uses.
What if the aliens we can't find are from the planet we can't find - and our little bug eyed buddies don't want us to find it? 🤔
Found it brilliant . In a few minutes you realise why SETI's job is so difficult(impossible?) . You also realise how precious human life is .
Except for being a jackass about DJT.
And religion.
I can only imagine the reaction of an ET after receiving one of our radio broad casts....Would they classify it by WOW too ?
The "Wow!" signal is exactly what should be expected when both sender and receiver are on rotating planets in star systems that are moving at terrific speeds. You'd probably get a brief signal that didn't repeat because you'd rapidly move out of alignment and the signal would no longer be directed toward you. And at interstellar distances signals are incredibly weak.
it depends on how hungry they are
LWA, leave well alone.
If we were to ever pick up a signal from space that is like the barrage of tv and radio transmissions that we put out, even if we have great difficulty decoding it, the mere fact of the existence of ET will cause us to re-prioritize our R&D and getting into space will become very important for everyone.
It has already happened ! , how do you and most others not know this? The nazis did it with their Vrill Society and Tesla himself said he got a lot of his information that exact way. It just depends on what you believe , the problem is most people these days don't believe in much.
we are clearly alone or we would have picked up plenty of signals by now
@@Withnail1969 we haven't even explored our local galaxy yet. Much less the far parts of our galaxy. Also who says it has to be intelligent life? Id be super excited if we discovered small creatures on another planet
@@daltonpechon7335 we dont need to explore it to receive radio signals
@@Withnail1969 who says they have to have radio signals
They've already found us, they're already here. @t
@Lord Kenyon How do you explain UFOs
Trying to pretend Earth is still trying to contact Aliens when government know they’re already here
I think it's more like primitive life looking for advanced life
What if the aliens we can't find are from the planet we can't find - and our little bug eyed buddies don't want us to find it? 🤔
We may have to consider that "intelligent" life, e.g., an intelligence that uses technology in our own manner, may be several trillion more rare than previously estimated. Not a happy prospect, but one that may end up being a reality.
We are not alone and never were. There is life everywhere in every part of space.There is no place where life does not exist always from 3D to 12D.
I called SETI once, no one would talk to me, I felt that was wrong of them
Advanced ET civilizations do not make contact through electromagnetic communication devices, but through consciousness. If SETI would invest it's 100M$ budget on CE-5 related projects we would be in a whole different new world.
We should be concentrating on the search for terrestrial intelligence. So far no one has been found.
Moore's law projections are so outdated on that slide. Last data point from like 2002? Computers hit power wall by 2006 (Dennard scaling), and by 2012-15 it slowed down significantly. Heck, we've been on the same node for the past 4/5 years now. Industry is struggling to reach 10nm, let alone smaller.
Where do I find the app ??
Gotta love how SETI sent out directions to earth without asking the rest of us if we were cool with the idea...
50/50 odds they’re friendly explorers vs. parasitic colonizers.
It wasn't SETI who sent out. I think it was a UN or a US initiative. In any event, the hyper extraordinary energy required to travel and communicate between stars is highly unlikely to have arisen from a combative rather than a collaborative enterprise, so I would suggest that any advanced civilization which choses to contact us is about 90% more interested in assisting us than eating us, though more like 95% more interested in ignoring us.
Holy_Hand_Grenade-of-Antioch they’ve been here since the beginning. They made us. If they were hostile we’d have already been destroyed. Remember when we sent that info out into space from the Arecibo radio station in Puerto Rico way back in the 70s? They replied with a crop circle in the early 2000s I believe with a response to our message. Look it up. It’s proof positive to me. Evolution theory is lacking many vital answers to our questions... where’s this “missing link”?
@@MichelleDespres and that's it? so you feel there's no other intelligent life other than us and our monkey makers?
Well either way you have to admit that it would spice things up on this planet.
Pretty much absolute probability any alien civilisation will have out competed millions of species on their own world...they will be, like us, the apex predator...there's no 50/50 about that.
Since 1982, humanity has gone from E.T. to E.D.
8:58 it actually zapped 2020, a line of cables broke
It would seem to me that ETS have already found us and when their ready, or when they evaluate that we're ready, they'll make themselves known to us. In fact, this may have already taken place and it's our leaders who are keeping this information under wraps.
Not sure what’s more terrifying the fact that we may not be alone or the fact that we are.
In the movie Contact 1997, Jodie Foster intercepted and decoded an alien message that gave us the plan on how to build a time travel machine. The technical plans in the message was encoded in the track between each frame of video. So the government built one (two actually). And Jodie went somewhere and talked to the "alien. Great movie!
What if we encode a message in laser beam pulses, like a morse code with short and long blank spaces between each laser "chunk". That would "identify" them as artificial light. Then the message can travel at the speed of light.
Then, broadcast the laser message beams from points of the globe to cover the whole universe. Then wait for the "reply"..
Great movie. One of the best science fiction movies ever, in my opinion. It was very intelligently made, and did an excellent job of blending its more fantastical elements with hard science, and then synthesizing the two approaches perfectly by the end.
Cool idea, by the way.
That's basically what Aricebo did in the 70's.
He didn't do enough research when he quoted Moore's law. Moore's original law has been stagnating for the past few years and from Moore himself, "I see Moore's law dying here in the next decade or so" - 2015. Computers are becoming more effective due to advancements in the understanding of quantum mechanics and designing chips that don't follow the standard Von Neumann architectures; as well as many other technologies.
I bet that’s no longer in Puerto Rico after the hurricane.
That's my first encounter with a violent bashing of Carl Sagan's voyager: "porno to the stars", really?? Indicating our position out there on that golden plate is foolish, I agree. But the man was a poet and it was fantastic reality TV.
what else would you expect from a jealous college professor.
That's right, a little bit.
Alexis: I do agree it would be foolish to announce our position but Voyager is to slow to really get anywhere & they knew that. It was launched 40 years ago & just now left our solar system. If anything is going to announce our position, it will be the high powered radio & TV broadcasts starting 90+ years ago and are still traveling through space 17,000 times faster than Voyager. Even signals sent out by Voyager will forever be 50 years behind early TV & radio broadcasts.
Voyager's main function was to get people interested in science, the universe etc & exactly like you say, it did that beautifully. It truly was fantastic reality TV.
Thank goodness Star Trek has already addressed a lot of the ethical issues
Sheree Pfeiffer War. Poverty. Disease. Star Trek tackles the big ones.
I am mixed on this.
How do we balance the introduction/invasion of one species into another environment due to man's intentional/unintentional actions against human's pursuit of short/long term values?
Aren't sidewalks, lawns, roads, and buildings like an alien species in an environment? Therefore, should human migration and spread be minimized or eliminated so as not to harm an environment?
Is any configuration of nature better than another? Better for whom and for what?
Like any discussions about values, the answer will be gray not b/w and should be resolved thru politics.
All Hail the Great Picard ! If we kill the ones who angered him, he will give us Favors, he can bring back those we lost last winter..
The Prime Directive a good starting point?
Could be a fun discussion. As much Star Trek as I've watched yet you bringing that up got some rusty gears in my head turning..
(Inject random hate comment hear) continue statement..
Great point, I guess it's like Antarctica and the guy who tried three times to sail there. Out in the middle of nowhere while trying to stay away from shopping lanes and being seen. He was caught and taken to South America.. the third time they showed up with enough pieces of his boat to identify that they stumbled across his wreckage by chance floating in the middle of nowhere and no survivors.
We aren't "Allowed " to see the universe, let alone Earth...
The original ideas to communicate wit ET are probably not much different than us looking for radio signals.
Of course we're not alone. The aliens are just too far away, and even if they could master faster than light travel, they wouldn't care.
I sure hope there is intelligent life somewhere because it sure isn’t on this planet!
Ha Ha ........ I love you and Lucy..... Peace baby

Summary:
- No ET so far
- We're still working on it.
Thanks. The title alone lets me know this guy doesnt have a clue. Not a single clue.
@@jondoe2099 It's his own summary of what he talked about
@@workingonanames thats fair. I guess when your looking at title to get an idea of ptesentation, it comes across as he doesnt know if we are alone. (Obviously not alone.) Very good point you made.
We are alone. This summary will be on a slide in 100 years
Solution for SETI and the Fermi paradox:
Scotty, we looked everywhere, all over this blue planet, but there is no sign of intelligent life, just beam me out of here!
I use the lights on my blue tooth speaker.. It works great
I remember the running SETI at home in the 90s, the first P2P collaboration I recall hearing about. Paved the way for Bittorent and then of course Bitcoin. :D
A ET race responded in the crop circles, now what?
Lol

Very fond memories of my own efforts. I built a dedicated gamer CUDA capable machine for the purpose of achieving the most production for the least power home PC on the planet. Fanless platinum power supply, smallest cpu chip capable of driving the game boards. I ganged two motherboard powered NVIDIA GT-650s with two wired EVGA GT-650s.
The results were good. Mostly it just sat their all day crunching numbers. It produced about 100,000 credits (cobblestones) per day drawing about 250 watts. Over a year or two I had accumulated enough total credits in all the BOINC associated projects to rank in the top 99.98% on the planet. Tens if not hundreds of millions cobblestones. Then I upgraded one of the NVIDIA gamer boards and crashed the entire system. I was the only guy in the county who had ever manage to gang up four parrallel CUDA boards and even I could not set this mess straight. So my system has gone dark.
I see that information map and cannot help think about there areas left out.
So if I found et life, do I put my name on it? What is in it for me?
Why, as we search for intelligent life...don't we factor in the thousands of "UFO" sightings and experiences that we have had???
Julian Wilde because people claiming they might have seen a ufo is not conducive to scientific research
A 8 that didn’t age well...
LOL yeah, I guess they're just waiting until ETs will finally introduce themselves to the public.
If a legit one ever happens, someone will take a look.
Btw look up.what UFO means. It doesn't mean alens
Adam N Is looking at the stars not scientific? It’s just people looking at something. You have to first observe something a study it to make a science of it. The evidence for intelligent life visiting this planet of overwhelming. And now the government is finally coming clean. More disclosure to come. Stay tuned. Go to r/ufo to learn more.
File the elementary school anecdote in the "things that never happened" folder
What if we are seeing the et's far past due to the delay in the reaching of there light to us???
Anything wrong with acknowledging multiple images of Martians in the Curiosity Rover footage?
An article in the September 2018 Scientific American makes a compelling argument for the conclusion that we're probably alone in this galaxy. For example, we have a n unusually powerful Van Allen belt and a truly unsual big Moon--the the result of a collision between Earth and a Mars-sized planet over 4B years ago. That collision gave us a thinner crus--which became the Moon---and a thicker Iron/niickel core; toghether those enable plate terctonics, stabilize Earth on its polar axis, prevents space radiation from sterilizing our planetary surface and from the surface getting weather too violent for advanced life to exist. Plus the discovery and mapping over 320 planets in nearby solar systems shows that our configuration is unique among them, further lowering the likelihood of an Earthlike planet out there. I'd love the galazy to be full of intelligent life, but it's becoming clear that we understimated how unusual Earth is. Too bad we're destroying it, because thrre's no Plan B out there.
There's trillions of planets in our galaxy alone ridiculous to conclude there couldn't be any others with similar structures and environment to ours
Um so life can only live on Earth-like planets? Why? Even on our own planet it lives in a bewildering variety of circumstances and has an incredible ability to adapt to them.
if we find Life on Europa so called articles will be burned and cease to exist as everyone celebrates the fact life exist in different conditions. Our moon might of played a huge part of our existence but it also plays a huge part of our Religion superstition that help feed us. Also right in our solar system Pluto has a similar issue. Its moon is like our moon very big. So for 2 planets dwarf or what not in 1 solar system to have that probably suggest that the big moon is much more common then you think. your whole thing revolves around the Moon being rare. Now that its debunked we can say while rare in our solar system its probably not in our galaxy.
The vastness of the universe and the fact that it's expanding close to light speed if there is intelligent life it disappeared. The deep and the deeper space pictures from the Hubble scope has not seen a grade 3 civilisation's smiley face.
Yea right so that you can then forward everything we do to NSA.
So who's gonna do the setti program up
Great personality!
If it wasn't for government contracts, this guy would be living under a bridge.
God is an alien. ✌🌐
How about if you looked down & saw three prmids in a row. Wouldn't that be an inication that maybe an intelligent being created them?
There is intelligent life in our galaxy, but not human like intelligence, there might be and surely be like apes/dolphins like. So for for human like intelligence we need to start lookin at other galaxies. These latest studies start to show the fact that Humans seem to be the most developed species in Milky Way. Good or bad? Who knows? Maybe we should be proud of that.
@PJ Vent Never assume anything, it starts to look like we are the most intelligence species in the Milky Way. Sorry mate, or show me civilisation that outsmart us!

It seems everytime I hear about this habitable zone i disagree, temperature seems not as concrete as stated. What you need is a planet with water. The distance from the sun seems not nearly as important as I think led on. 4/5 of those based on temperature alone are habitable at some point.

Venus + 870 °F (+ 465°C) + 870 °F (+ 465°C)
Earth - 129 °F (- 89°C) + 136 °F (+ 58°C)

AWESOME
I am surprised at how thin skinned some people are . Instead of taking the time to comment on the content of what was presented by a speaker who apparently has many years of experience in this field , they choose to dwell on on a comment or two about some two bit politician enjoying his 15 minutes of fame who is quite frankly, here today and gone tomorrow. I for one will be downloading the screen saver on to my PC.

I agree.
"They" are already here, and have been for a very long time. Forget SETI, Silly Effort To Investigate.

The data is being analyzed. The problem is no alien signals have been picked up.

It would seem he believes his personal political bias is important to the rest. After his political wisecracks, I lost in his talk.
scientists can be cucks too...
@@mycount64 I'm afraid that I must disagree with you. Everything about SETI is political. People who make their living by pushing the SETI belief system must be political animals in order to appeal the people who fund them. Generally, the people who fund this nonsense are shallow thinking liberals with much education in biology or the other sciences. The way to reach these people is by pandering to their political views, and that is exactly what this guy is doing.

How these scientists conclude "we are alone" is mindboggling! Why don't
any of them factor in the progress of a growing intelligent engineering
and scientific capacity as another part of the equation? Have they all
forgotten we couldn't do much better than walk anywhere some centuries
ago? Or that we would die of a common cold, and be eaten by Tigers ?
He said that in that year long metaphor of the Universe's existence, we
came in during the last 12 hours of the year, but life in other worlds
could have been existing for six months. WELL ... how capable would some
of those intelligent beings be by now THEN !? I think we all need to
face the fact that what we don't know or understand yet, is why THEY DO
NOT WANT US TO KNOW THEY'RE THERE ! Or why they may have to wait for us
to confirm to ourselves that they are there, or reach some phase of
development, and that they have always been there even before we were
here, waiting for us to realize that without needing to prove it. In
other words, a 180 degree turn around from how we think of it today.
There's nothing to discover or prove. We are either their plan, their
intention, their monitoring, their offshoot, their children, their
workhorse, their thing they do or created for whatever reason... we just
don't know. They're either watching, or waiting, or using us, or
raising us, but what we do know is that the situation is reversed to how
we are thinking about it. None of these guys factor in the exponential
acceleration of intelligent material and communicative progress ! It's
unbelievable .
Aren't people just stunned that scientists themselves are not saying
this?
Talk about your topic not the President pls
Stopped listening with off hand comment about President Trump andderrogatory comments about boys v. girls.
yeah if youre a fan of trump you should probably stay far away from science and just keep watching fox news
One more thing as when we go to other planets we see rocks, ice might be possible ET always look at Antarctica and they haven't find there
We are looking for "intelligent life". Intelligent life is defined as a civilization that sends out repeating signals that can be located. We do not send out any signals like that, therefore, we are not "Intelligent Life."
I was loving this until you kept talking about Trump keep politics out of this s*** man
Republicans pulled SETI's funding 1 year after it started. Science=Progressive, Pandering to the Religious=Regressive. Politics is a huge part of this. (Those SETI telescopes shown just happened to be 2 of the first to ever "collapse").
John O'Hara you realize trump gave nasa a budget bump after Obama cut them for 8 years right?
SETI's search for ET has NEVER received funding from the government. EVER! All such research has always been privately funded. SETI has on occasion received government Grants and has partnered with NASA for special not ET related projects. Obama is the one who pulled funding from NASA and others. Trump actually restored funding.
Yes, I had to stop the video because his comments made anything he said less credible with me.
Lord help me. I can't even try to learn some science without an intellectual bashing Trump.
Note to this smart guy. Blue collar working people want to learn and explore. Keep your propaganda to yourself.

Trump and the search for intelligent life in Murica !!!
How would we react to knowing that humans are the only sentient life in the universe? What would be more incredible, that we are alone or just one of many?
Life was created quickly but first multicellular organism was mutated only billion years later. What makes this milestone very unlikely event.
Unfortunately, I think his jokes and references undermine his credibility somewhat.
Ed Mathews totally agree
I am reading the comments but can't waste my time watching the video with a guy since he stated we been asking if we are alone since a few hundred thousand years, he clears have no clue about human evolution or timescales, how can he handle such a complex subject?
In what way? Donald Trump is a joke in so many ways.
Lost me by making underhanded political digs, despite the seeming decent ideas regarding how to get a hold of ET. God help us all if they encounter Californian University gasbags first.

When indeed. Consider that we have had radio for about a century at this point. If we continue to use radio in this way for a thousand years, that's a problem.
If there are about a million worlds that are somewhat close to us and visible in our galaxy that have once used radio as we do now, that would mean, over the last few billion years, they would have given off a pretty clear signal of it. You see, we here on Earth are many times brighter than the sun in these specific radio wavelengths. In fact, we stick out like a sore thumb when one switches between regular visible light and radio light.
First, if we assume that radio is the be all and end all of long distance communication, then, if there were even just thousands of civilizations in the nearby part of the galaxy, still using radio presently, we should see plenty of them out there. But we don't.
So eventually civilizations replace radio, or dies trying.
But how long do they last with radio?
So let us assume that there is some combination of how many radio civilizations there are in the nearby part of our galaxy, at any one time, and also assume, on the average, how long they stay with radio, also on the average, in order that over the last few decades, we haven't seen the evidence of them, despite looking.
Let us assume that for the last 4 billion years there has been the opportunity for a civilization to arrive at radio. That's a fair amount of time after the galaxy formed, about 8 billion years, give or take a billion.
The fractions are within a single order of magnitude, so we can work with that.
At 4 billion years, at 10 million civilizations, on average that means that the limit is that every 400 years on average a new one appears locally. Let's say that we've been watching for 100 years. Under these assumptions, we could watch for an average of 300 more years before detecting another one of us just starting. However, if they hold on to radio for 1,000 years, we should see at least 1 or more of them at this time anyway.
So, locally, there should be less than 10 million such civilizations, and they should last with radio for less about 1,000 years each, on average. Otherwise, that's 10 billion radio years in 4 billion galaxy years. They should be easily found around us. So that's a kind of limit on these two variables.
However, for instance, if there were only about 1 million such civilizations, out of the billions or so suns in our galaxy, that would mean a new one appears every 4,000 years. Even if they last for 1,000 years, that would mean a long enough, on the average, wait in between them so that we wouldn't see them if we looked for say 100 years.
Or there could be 10 million or so such civilizations, each holding on to radio for slightly more than 100 years. That would do it too, on the average, but not for 100 years of searching, unless we were particularly lucky, or unlucky, depending.
What this means is that, since we don't see many neighbors with our obvious pattern of visibility in visible and radio wavelengths, one of 2 things is true. Either being a civilization with radio spells doom for it within a short period of time, much less than 1,000 years, or they are smart enough to graduate to something else, and become effectively radio dark within a fairly short period of time after the first 100 years, or so.
I pray that it's the latter.
If so, however, then that establishes a different problem.
What replaces radio?
Is it some kind of sub-space radio, that takes advantage of the 4 dimensional sub-space that we are really in, as a 3 dimensional surface universe? When do we start to properly investigate hyperspace so that we can find this novel form of communication?
Perhaps we must find a new model of the standard model of particles that explains dark matter as a 4th, and above, dimensional model of this invisible matter and energy.
Do we have a 3-ball model for matter? Yes, we do. It's called the TRIMOBIUS(R), and was patented under US Patent 4,138,744.
Go figure.
Let's start an investigation right away.
Huh?
There is life out there we have to change our bodies hence project human 2.0 and faster ships or non human missions using robots. If the big bang is real all life no matter how far away from us it is is about the same age only that matter may work different in that galaxy or part of space. Its not a matter of when we find life elsewhere will we servive with our differences here to have such a discovery bestow onto us.
Politics yay! Stopped watching. Too much TDS going on.
Ryan Culp trump is deranged enough. no need for tds
Then he says right after that boys and girls are different adding "unfortunately" to the end of it. Yup. What a freaking far-left weirdo.
@@aujax1 His opposition daily says "hold my beer" tho. Its a competition none of us care for.
