Stephen Hawking says Aliens exist

What I don't buy isn't the existence of extra terrestrials, it's the claim that they've visited us and are did/are doing X.

His logic is the same way I think.. but I think this was the most important quote of the article:

“Just as a chimpanzee can’t understand quantum theory, it could be there are aspects of reality that are beyond the capacity of our brains.”

We might not like to admit it.. but there are many, many things we don't understand.

Yep. There are probably ways of interstellar communication that we haven't yet thought to search for. I was only stating that hostility or the presumption of hostility COULD be one reason or even possibly the main reason why we haven't heard anything as of yet... But this was really just a side detail. My main point was that some civilizations might reason that it makes sense to take preemptive measures against other forms of intelligence to ensure their own safety. They may even decide, that given the stakes, they have no other choice.

I disagree, we know what are so called troubles are, large corparations, the greedy people,the one's who claim to be royal,these are just a few of the ugly we have on earth .either incarcerate them,or eliminate.

Its not we are the grandest in this universe. The governments ruining everything with their power. Remember what carol Rosin said a few years ago.

Werner von Braun told Carol Rosin the next thing, which Werner von Braun experienced in his time when he producing rocketry for Hitler and after that for the US.

"First it will be the russians, then it will the terrorists, then there will be 3th world countrie's which we called nations of concern, then there will be astroids, and then he repeat to me, the last card, the last card, the last card, there will be extraterrestial threat.

The last thing we dont need to do in this world, is putting our selfs aggressively against Alien races if the time will come. Thats the problem with the nature of a human mind, it wont never happen.

We are so ignorant, selfish. Instead of putting alot of money into wars, we could use that money to make a global cooperative space industry.

We are just "lemmings" following and obeying our goverments. Alot of people having a desire to be enlighten (at least i have).

For the people who never watched the video. You should watch it.

Why do the nations conspire
and the peoples plot in vain?
The kings of the earth take their stand
and the rulers gather together
against the LORD
and against his Anointed One.
"Let us break THEIR chains," they say,
"and throw off their fetters."
The One enthroned in heaven laughs;
the Lord scoffs at them.-Ps2

The LORD will rise up as he did at Mount Perazim, he will rouse himself as in the Valley of Gibeon— to do his work, his strange work, and perform his task, his alien task.-Is28.21

Stephen Hawking says Aliens exist.

I taught he coudn't speek...

If aliens have evolved far enough to visit this planet,they will
either regard us as a source of study, OR...a source of food.

We have lots of green-leafy, and pink-flesh bio-mass down here, and quite
a bit a water to wash it down with.

We have to assume aliens eat, breathe, and poop-like us. And we have
to assume THEY consume less fortunate or intelligent species.

Or, maybe they'll regard us a cool pets for their kids, we don't eat puppies
after-all....well, some of us don't.

The most likely scenario is that aliens have been visiting this planet
since life began to evolve here. They do not require anything we have,
or if they do, they already have it. We are probably just a curious
source of study for them. with an interesting DNA strand.

"...The planet is full of water-based life forms. Mostly photosynthetic plant
species on the surface with many species of bi-pedal and quadra-pedal
animal forms as well. This planet is notable for the vast amount
of sodium-rich water which covers most of its surface, and for its
most intelligent species, Humans, which dominates all other species
and is currently in stage one transition from instinct to intellect.
Interestingly, this species has developed the technology of nuclear fusion
explosion far in advance of the norm and this anomaly makes this
specie's quest for survival one to watch..."

For someone so smart,
he says some stupid stuff!

I dismissed Hawking years ago - he's old hat...

Based on what? Because he telling the truth? That would be "stupid".

Some calculations:

From the Atlas of the Universe we can see that our visible universe - which spans over 14 billion light years - contains an estimated 30 000 000 000 000 000 000 000 stars, or 30 billion trillion stars. Within that astronomical number of stars it seems mathematically inconceivable that there wouldn't be many other civilizations somewhere.

However, it is also obvious that we will never be able to communicate over such an enormous length of time, and any intelligent signals over such an immense space would diminish practically to zero before reaching us - for it would be swallowed up by millions of intervening galaxies.

Our own galaxy - the Milky Way - contains 200 billion stars, but it is still to large for effective communications, because its size - 90 000 light years - would require 180 000 years for a two way communication.

I think you will find, if you did a survey of the populations of many countries, most would probably agree that there may be life somewhere else in the universe. I certainly do. The odds are for it totally.

But the odds are against the greys jumping in their triangle and saucer shaped space ships and visiting earth to anal probe people and steal cattle.

Alien life elsewhere = very possible

Alien life with superior technology that come to earth and very effectively manage to defy all efforts to not become a public truth = almost impossible.

Bit of difference there.

he's a flip flopper. Fence sitter. and downright illogical when it comes to the ET issue...

Only a little while back he said there was no ET life...

Now he says there is - but we should hide from it?

He's entitled to his opinion - but that's all it is - and my opinion is screw that - I want full open up and say AHHH wide contact - the sooner the better!

Hawkings has always come across as a puppet to me aswell (again in my opinion)

It sounds like Hawking's view of alien life is informed by the film Independence Day.

Also, why would aliens colonize earth, as apposed to any of the other billions of planets in the galaxy? Yea, maybe earth is special? I don't know.. but if your whole civilization can move off the planet in a space ship, one would think they would be advanced enough to mine the resources on any of the other planets/moons in the solar system, while leaving earth alone; but who knows, really.. alien life is.. alien.

[edit on 24-4-2010 by Kaytagg]

Ah well, a notion that it would be in the interest of an Alien species to harvest the animals on our planet, including Humans...
Then also humans could be used as laborers etc...
You'd imagine all sorts of possiblities if your facing a more powerful entity.
It's called survival of the fittest.

I've also stated myself that Aliens/Extraterrestrials from another world would most likely arrive in our Solar System in a large Ark type vessel, that probably would have been travelling through the galaxy stopping at planet after planet utilizing chemicals, matter, and other things.
If they would happen to stumble upon our planet, it would be a terrible event. You would be facing off against a species that would likely want to exist on Earth, due to the fact that Earth is so hospitible to life...

Earth is rare, out of the 9 planets in our solar system, Earth is the only planet that can support and harbor life in many forms.

actually, yes i do. i've even read "a brief history of time".

if you had read my posts, you would see that i said i hadn't decided one way or the other concerning my belief in alien life. sometimes it seems plausible, others, not so much.

i'm actually a fan of some of his theories, "hawking radiation" being one of them.

it is really sad that instead of providing evidence on odds, you laugh off my evidence. people who are afraid of being wrong fear truth.

I like your evidence, instead you claim some guy determined that there are a set number of variables that must be met inorder for life to form, without intervention. Now tell me, how did he come up with this? Was he around when life sprang up? There's a good chance that aslong as you have a planet with an active core, you'll have life. Active core leads to active planet, which leads to nice thick atmosphere......keeps going. Then again I'm going off the top of my head right now, but what you proposed is just ridiculous.

Also anyone who thinks ET would be advanced enough physically and spiritually that they wouldn't need to strip our planet of resources need to wake up. Seriously NO ONE knows one lick how ETs would act, but then again to err on the side of caution we should assume they would be like us jack*** humans who only care about ourselves. Hate to say it guys but humans are selfish and I have a hard time believing advanced life elsewhere is any different. Do I know what resources they'd want from here? No, I don't. It sure as hell wouldn't be oil unless there's some use for it we havn't found yet.

There isn't much else I can add.

[edit on 25-4-2010 by Judohawk]

no, they were not thought up by one person. did you even go to the link, much less read any of it?

they are constants that, with a small amount of variation, would make life impossible in the universe. (some of them only hold true for carbon based life, but many do not) at any rate, they are worth a read.

these aren't hashed together principles made by creation nuts, (and yes, i'll admit, many creationists don't know a lick of science) but quite well defined principles. i'll give you a few examples.

"Helium Formation the existence of an 'interesting' level of Helium in the Universe (not 0% or 100%) depends on the coincidence GFme2 ~ (Gme2)1/4. were this not the case we would either have 100% Helium emerging from the Big Bang or 0%."

"Enough Mass in Universe Mass of Universe = (4p/3)rl^3 so Mu ~ 10^5 tu MSun so must be ~ 10^23 Msun"

at any rate, i still hold that the odds are against life in other parts of the universe (if you don't accept creationism)

www.starcourse.org...

edit to add:

mmmm...sadly it seems that copy/pasting equations isn't the best idea, as they don't retain their exponents/greek letters. go to the link and read to your hearts desire.

Dude Hawkins OWNZ

I have always admired him. Have you read his books?

Fascinating.


For those of you who tow the official line.

haha that one make real laugh!!! Good one!

reply to post by Wertdagf

stephen is an idiot if he thinks blood thirsty pirates with warp drives and plasma cannons are gonna have spare time to take over other planets. They will be very busy killing eachother.

You continue to outdo yourself in unpleasantness, Wertdagf.

Prof. Hawking (I had no idea you and he were on first-name terms) has, I think, adequately demonstrated to the world that he is not an idiot. Despite his many physical handicaps, he is not only one of the world's most famous people, he is also a successful family man and not exactly short of cash, either. That is to say, he is one of the most potent alpha males currently towering over the human species.

When it comes to a choice between Wertdagf's opinion and his, I know which one I'm likely to be going with. Not that I need anyone's opinion to know that your statement is arrant nonsense. Warlike races have managed to conquer vast tracts of the earth despite their propensity for internecine violence: the Romans, for example, were forever having civil wars, coups d'etats and the like - even a slave rebellion - but that didn't stop them from extending their empire from Egypt to northern Britain.

As for dealing with other, equally warlike races they encounter: space, as you may have heard, is big. A predatory species could spread through a vast volume of it before meeting its match, overrunning and looting many planets and destroying many intelligent but less militarily capable species in the meantime.

But to explain all this is only to state the obvious, really. I do so only because irked by your arrogant and boorish post. You seem to specialize in that sort of thing; for my money, you are currently the leading practitioner of gratuitous discourtesy on ATS. Learn some manners, can't you?

as much as i love hawking, his logic is flawed, he has underestemated the odds. there are things called "anthropic constants". basically, precise and narrowly defined variables that must be exact for life to exist.

"Astrophysicist Hugh Ross has calculated the probability that these and other constants (122 in all) would exist today for any planet in the universe by chance (I.e., without Divine design). Assuming there are 10^22 planets in the universe (a very large number: 1 with 22 zeros following it), his answer is shocking; one chance in 10^138, that’s one chance in one with 138 zeros after it. There are only about 10^70 atoms in the entire universe."

do i believe that life exists elsewhere? meh, i'm not sure. but to claim that the odds are in favor of life existing elsewhere is silly when the chances of life existing on our own planet is so slim.

That's a pretty narrow-minded way of thinking about it. This is the Universe we're talking about. We don't know how many planets there are, and we don't even understand how large the Universe is. To even mathematically calculate this with so much missing information (unless you make stupid assumptions, like the guy you quoted did) would make it incredibly inaccurate. There are so many unknowns -- we know very little. I am going to assume (like the guy you quoted) that life is very abundant in the Universe. I don't even see how it couldn't be. The math above is just full of a bunch of guesses.

Also, I tend to think there are more than 10^22 planets in the Universe. A lot more.

Peace.
One Love.

In my opinion, the real question isn't IF "They" exist or not, but WHEN "They" made the Public CONTACT.
Are we ready for this?
