Is Stephen Hawking's Take on Aliens as Funny as We Hoped?

In summary: He's just doing what any other person would do in that situation- hoping for the best while preparing for the worst. And honestly, if we don't make contact with aliens soon, I can't see us doing much better.In summary, Stephen Hawking says it's perfectly rational to assume intelligent life exists elsewhere, but warns that aliens might simply raid Earth for resources. He also says that if we don't make contact with aliens soon, we'll probably do worse.

My question would be this: Why does Hawking make such an extreme statement?
Instead of "balancing" that idea, he basically say's "avoid all potential alien contact"

I'm losing some respect for him...

Maybe he knows something we don't know? Maybe he's had contact?

Now don't make me ban you! :biggrin:

Seriously, highly accomplished scientists are not immune to exotic beliefs. However, I didn't think his comments suggest that he expects that we will make contact, or that we have, only that if we assume it to be possible, we should avoid it. There is nothing wrong with logic applied to an assumption, as long as one knows they are making the assumption. Perhaps he believes that exotic transportation technology may one day be possible, in which case we would have to assume this is true for some ETs out there now.

Can you think of any prominent scientist that is more helpless, and more dependent on others? His personal situation and world-view may have some bearing on his attitude. Why would any alien races expend time, money, and resources to come here, only to expend more resources eliminating us (or enslaving us) before they had a bit of time to evaluate their options?

Can someone perhaps explain what it is exactly Stephen Hawking has done to make him so well known? Yes his condition is tragic, but if he weren't confined to a wheelchair would anyone care about him?

We have no way to know. We can reasonably argue that there could be ETs over a billion years older than us. If there is still much to know about the absolute limits of physics and the other sciences, then a very old race could presumably be highly advanced as compared to us. For that matter, we can't know how long it takes of an advanced species to evolve. Were we lucky - a fortuitous freak of nature - or are we slow learners? Maybe we live on a dumb planet. :biggrin:

There are many reasons he is well-known, but his theoretical discovery of Hawking radiation comes to my mind first. This is more than sufficient to place him among the great scientist and makes him well-known among physicists. Also, his popular books allow him to be well-known among the masses.

Of course, his condition and characteristic mechanical voice make him hard to forget also, but that would hardly be sufficient in itself.

A more interesting, and harder to answer, question is whether he would have attained his notoriety and made great discoveries without his tragic condition. Clearly he always had the ability, but I can't help but speculate that perhaps his condition created a sense of urgency and focused his mind to very particular goals. I remember reading that he was a strong athlete and charismatic person in his youth. There were many paths he could have taken if he had stayed healthy.

I agree that intelligent alien life might be interested in studying, observing, and perhaps even keeping natural order protected. But what people are ignoring is the fact that humans are pretty much bad for the planet and it's natural treasures. It isn't a stretch to imagine them taking action to protect the natural order from humans, by eradicating us.

For what reasons should they be concerned with usany more than we are concerned with any more than we are of mosquitos or invasive plant species. Then there is also the possability they are enamoured with us, who knows.

You have to also consider we make good slaves.

“If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans.”-from the link provided, words by Stephen Hawking.

This can be interpreted in many ways. For example, when Columbus landed, European disease wiped out score of Native Americans. The same could be true with alien life forms spreading diseases to us.
Yeah, this is how I viewed his statement. Although, I wouldn't rule out the possibility of alien life having an aggressive or manipulative motive in dealing with the human race. What if we seemed to be more like ants to them or a disease that should be whipped out?

Yep

Who knows. Maybe we'd strike first. Human paranoia and all.

Perhaps, Mr. Hawking saw Avatar one too many times.

If intelligent life visited us they would be far more advanced than we are. We haven't even had a robotic space probe travel into interstellar space yet and we struggle sending men to the Moon.

They could be in the same boat we are, only they were stupid enough to go on a spaceship for a really long time.

Yes that's an interesting thought. I always find it comforting knowing that if something ever happens to me and I lose my legs, or end up incapacitated in some way that I'll (hopefully) still have my mind. Sometimes I think that if I were locked up in jail with nothing to do but study books in my cell that I'd be a far better student than I am now :smile:

I think people tend to either break as in the case of severe sensory deprivation, or they turn inward. For some, that experience means confronting things that they can't bear, but for others, as you say, creativity can be expressed.

I find it astonishing that Hawking does in his head, what most people cannot manage with a room full of dry-boards! That being said, he is fairly uniquely famous, but I would say "A Brief History of Time" did that. He 'explained' black holes to the lay community when people had literally no idea what they might be. Right or wrong, he also did it with humor, and pictures, and THEN you add the condition and "robot voice" and yeah, fame.

Given his declining health however, it's hard to tell at this point what to make of his statements regarding ETs. Either way, he's made people such as Susskind and Thorne famous to people who don't even know what Relativity or QM are, and that can't be a bad thing. Let's face it, after Einstein, and Oppenheimer and (spit) Wernher von Braun and more, scientists + the information age = public awareness.

I find it easier to accept than celebrity chefs. :biggrin:

Thank you pallidin. What I'd like to know are what factors predict which outcome someone will face. You seem pretty knowledgeable in this arena, do you have any idea?

Hmmm, you know, I've done some more reading on Hawking's view on this, and once you filter the media hysteria, he makes an excellent point. I doubt we face imminent threats, but more along the lines of, "do we really want to broadcast our nature and locations to unknown entities?". This is a lot of hype around a basic cautionary tale.

Given a number of possibilities, I believe Hawking's scenario is the most (marginally) likely.

A) It is almost a given that they have traveled a very long distance.
B) They probably traveled at near light speeds. This is a safer bet then say FTL, as it doesn't involve speculative exotic matter for worm holes and such.
C) They don't have a home to return to. Due to relativistic effects during travel their home, as they know it, doesn't exist anymore.

Which means...
D) They are NOT explorers! They came because they want something--and we have it! A stable oasis in a vast desert. When you get a glass a water at night and happen to see Mr. Cockroach is also sharing the benefit of said kitchen, do we not just step on it? Do we lose any sleep afterwards?

I don't see them destroying all the cities or wiping humanity out. Just swiping us aside whenever we become a nuisance.

A) True.
B) Who knows, and that assumes...
C) A life of a type and span that cares or experiences these effects

D) How does A+B=D? They traveled a long way based on old light from this planet, instead of exploring nearby regions? A civilization that cannot achieve FTL travel (entirely likely!)
seems to be going out of their way for what the Earth offers. There's little here on Earth that cannot be harvested from other planets and planetoids, and even water would be easier to MELT than to take here.

Do you step on a cockroach and except the infestation to abate? More likely, you avoid infestations in the first place.

I found Hawking's views very pessimistic too.

If an alien civilization discovered the secrets of the universe to such extent as to be able to travel through the stars to distant planets and/or galaxies, at speeds close to the speed of light or beyond, what could we possibly have to offer?

They can figure out how to master space-time, but they need help finding water? Making a burger? It's hard for them to figure out how we operate? They need wood for a fire? Ridiculous.

They could mess with us for fun, I guess, but I'm more optimistic than that.

We figured out how to go to the moon. But our scientists still study life, biology. They do it in labs and also travel the world looking for new species.

I personally just don't see it happening and it's a lot simpler my way. Author C. Clark said by 3000, man will have traveled to all the stars visible by the naked eye. I think he meant about 4000 in general. I don't think that's gonna' happen, not even one and further I do not believe that at any time in the entire history of the Universe, one intelligent life form has ever made physical contact with another intelligent life form, not ever. The distances are too great, the conditions too harsh, and the chances that two intelligent life forms exist at the same time and in relatively the same location in the Universe are extremely unlikely. Don't get me wrong, I think there is tons of life in the Universe but it's all happening at different times, different rates of evolution, and different levels of success. Very unlikely in my opinion to find two independently-evolved intelligent life forms in the same relative vicinity at the same time.

I think that it's best to just assume that we have no idea. The true reality could be so many different ways. I expect that the truth is far stranger than what most of us imagine and expect.

What if they are such master of the universe, that they can terraform Earth to suit their biology? What if their planet is going to be destroyed by an unstoppable force, and they had chosen Earth thousands of years ago as a replacement.

The point is, when it comes to reality, their is always a history and story which leads up to the present which you cannot predict. For example, when the white man colonized the new world, it happened to have been the case that they had particular beliefs and particular desires, and particular technology, particular culture, particular leadership etc. There is no way to know what ET visitors think, what they want, what they believe, and so on.

I know that there are a lot of humans on Earth that enjoy killing other species for fun, just for the blood lust. For all we know, they could come as sport hunters. Maybe they bring stuffed human bodies, cow heads, etc, as trophies and hang them in a wall with species they've killed from all over the universe.

Somehow, the notion that because they are so advanced, they must be so emotionally advanced and empathetic. It may be that the opposite, perhaps, emotion being a weakness in a sense has been left behind with the new ages of technological biological hybridization.

Maybe they don't have what we call emotions at all. My point was that because they are so advanced, they must not have any need for us or our resources. Anything being possible, it shows who's an optimist and who's a pessimist. I'd be ok sending signals out and seeing what comes our way (if it's possible).

What's the right course of action for us as a planet? Hawking's hope is that we stay hidden, or that we would see them before they see us, but is that even possible (under the assumption they are so much more advanced than us)?

How about the fact that if they are so advanced, and their intentions were to harm us, we wouldn't be having this conversation right now. :rolleyes:

If aliens visited earth, and were anything like us, I would be very afraid. They would probably view Earth not unlike british petroleum does a newly discovered oil field. A biologically active planet might offer valuable molecules. I doubt they would perceive us as much more interesting than a fungus infection.

I think everyone here is giving too much scientific credibility to Hawking. Number of his practical inventions = 0 and to me that's not much credible.

Plus he took part in so many movies, self-proclaimed himself father of the universe, plus all the books and so on, that guy is a celebrity, and a strange one...

He had not lost his mind, he is simply doing some crazy talk to advertise the new shows he gets $$$ for being a consultant. A slang term would be "pimping" those new crazy idea shows.

I'd suggest aliens, capable of reaching other star systems would be not only advanced technologically, but also conceptually, and would know better than Cortes and his cousin, who slaughtered the majority of native americans and burned all their books, that contained information about planet orbits around the sun by the time "white" people still believed the universe revolves around Earth in some illogical way.

Most of you are over looking the moral of the story. If aliens could travel here we would be at their mercy. Also even if they were equal to us in every technology but found out a way to travel through space at tremendous speeds if you could fight a war from orbit you would win, because you don't have to live there when its over, or just release short acting biological or chemical weapons into the atmosphere undetected and you have a ready made colony with infrastructure.
Also some more food for thought traveling at great speeds might be a lot simpler than we think. Think about this if you look at a wheel and axle you would think any idiot could design this, and that's true; however, it didn't occur to any of our ancestors for thousands of years even when the means lay right in front of them.
Also I wouldn't bet the survival of the human species on your naive, idealistic, fantasies of any interstellar group as being some sort of Utopia of science and reasoning. Yes reasonable people and the exchange of ideas is the way we know our civilizations have developed technology, but in the end it was the strongest that was the civilization that survived. Also you don't know if the aliens stole the technology from a benovelent insterstellar society. Again the moral of the story is we would be at the whims of a species not our own.

Although Hawking has suggested its perfectly rational for us to think there is intelligent life in the universe... he also mentioned that intelligence is probably a bad mutation with regard to survival of a species.

"It is not clear that intelligence has any long-term survival value."

http://en.wikiquote.org/wiki/Talk:S...intelligence_has_any_long-term_survival_value.

This is a reference to our continuous degradation of the resources that serve to continue our survival, water, air and earth. All of them are being polluted at a rate that out strips the rate of natural replenishment and filtering. Hawking's quote also refers to our propensity to spread viral disease amongst our selves and our threats to, if not acting on, nuclear annihilation. All these anti-survival traits are a result of intelligence.

As far as I remember, Hawking also mentioned that because intelligence appears to be such a poor selection in terms of survival of the species, if it has been naturally selected on another planet in another system... it is fairly obvious that that "intelligent" species won't survive long... either. So, why would we expect to meet them?

You could twist it around though. Perhaps organic life is limited because we can't understand machine emotion? We are only one tiny part funktionslust in our experiences. Most of us rarely experience it at all (master craftsmen and athletes a bit more so.) There might be an entire spectrum of emotional being we miss out on simply because we are not stamped fully made out of an assembly line with a predetermined purpose.
Machine intelligence might be the norm out there ; and we might be the flukes.
We might be the species that lacks an emotional existence compared to machines. Perhaps only a machine can experience true funktionslust: the joy of being attached to what one does.

Comparing emotion is always a matter of perspective. When leveraged against a Universal background, who says that humanity has the grasp on what emotion even means?
To me funktionslust is all that is valid. I don't expect others to agree. I also don't expect that humanity as a whole has any monopoly on the emotional spectrum. There could even be greying states of quantum-like superpositions of opposite emotions as well as higher states of funktionslust we are incapable of feeling. There could also be more sophisticated symbiosis among aliens. They might find it horrifying that we don't communicate with our own mitochondria. Our very individuality might mean, to them, that we are incapable of feelings. And the opposite, perhaps the aliens are such rugged individuals that they consider us like a coral?

This is the problem with assuming we have some firm grasp on emotion and them on logic. Emotions can have their own logic. Even logic can change with perspective.

how much input does hawking has with these docos? he must have a lot of trouble communicating now & it would take too long. they probably just put his name on it & write his words? i vote aliens wouldn't even waste time looking at us, probably laugh the planet has gone past its use by date.

Stephen Hawking believed that there is a high possibility of intelligent alien life existing in the universe, but he also warned against actively trying to contact them as they may not be friendly or may pose a threat to humanity.

Why is Stephen Hawking's take on aliens considered funny?

Some people find Stephen Hawking's warning about aliens humorous because it is a playful twist on his typically serious and scientific approach to topics. Additionally, the idea of aliens being a potential threat is often portrayed in a comical manner in popular culture.

Did Stephen Hawking have any evidence to support his beliefs about aliens?

Stephen Hawking did not have any concrete evidence to support his beliefs about aliens, but he based his ideas on the vastness of the universe and the likelihood of other intelligent life forms existing in it.

What was the public's reaction to Stephen Hawking's take on aliens?

The public's reaction to Stephen Hawking's take on aliens was mixed. Some found it amusing and thought-provoking, while others criticized him for spreading fear and negativity about potential alien encounters.

Did Stephen Hawking's beliefs about aliens change over time?

Stephen Hawking's beliefs about aliens remained consistent throughout his career, but he did express a slightly more optimistic view later in life, stating that advanced alien civilizations may be peaceful and willing to communicate with us.
