Extra Terrestrials

[Nordac]

Do extra terrestrials exist? after all, mankind has been sending out messages for about 60-70 years now - by that i dont mean messages just for aliens, i mean things like TV programs, Radio Channels, the internet ECT - and yet, they have not yet made any formal communication with us.

Also what will they look like? Will they be little green men, or will they be, in my opinion, very much like us in appearnace.

BTW is this post in the correct area, or should it be in Science?

[Oli]

I don't think they would look like us if extra terrestrials did exist. What they do look like no one could have any idea, we can just let our imaginations run wild. I do think they do exist somewhere else in the universe though, they more or less have to. The universe is so extremely vast there must be more places than just Earth where living creatures have populated.

[Nordac]

I suppose what one will look like will depend upon the planet that they originated from.

EG - If it was a world that was dark, they would have large eyes

[Winfried]

The whole evolution thing all over again! woohoo!

Anyhow, if there are other races, it will be impossible to reach them. Let's remain realistic and don't get into all the science-fiction speculation and marvels (like travelling thousand times faster than light and such) please.

[Anarchistic Fascism]

I think there is some life out there.

But I don't think they will be anything like us.

I mean, they are extra terrestrial. That means they don't have to obey our laws of physic. I believe they might have explored our planet already, or that they are already among us. But the problem is that we can't see them, just like some high-pitched sounds we can't hear, we can't see the extra-terrestrial life. They might as well be very tiny, as tiny as an atom or even tinier.

We imagine them as humans, or little green man. I personally don't think they look anything like those two examples! I don't think our fantasy goes that far to imagine how an alien looks. They could have colours we can't even think of, if they even have a colour.

Scientists say that there could (have been) life on mars because there are examples of ice/water there.
Extra-terrestrial is extra-terrestrial, out of this world. And like I said before, they don't have to obey our laws of physic, hell I think they don't even need water to stay alive. Maybe they need rocks and sand to stay alive. Everything is possible.

[Nordac]

It wont be impossible for mankind to reach extra terrestrials, but it will be impossible for our generation to reach them, with our current level of technology in space travel... We will have to send a full thriving comunity to go and look for them on a large spacestation, which will most likely use a solar sail.

[Winfried]

That means they don't have to obey our laws of physic
The laws of physics are universal. And your theory sounds a bit like Douglas Adams. "Hyper-intelligent shades of blue" and such :lol:
Yes, it could be possible that alien life doesn't breath oxygen, or needs water to survive, but all of the life known to us does that (except for some bacteria maybe), so we assume that all possible life does it.

We will have to send a full thriving comunity to go and look for them on a large spacestation, which will most likely use a solar sail.
Yes, but even with technology that makes travelling at the speed of light possible, it would still take a thousand years to reach the nearest star. By that time the people must've forgotten why they're there, or if there is anything else except their world (in this case, a space ship)

That's exactly why humanity hasn't succeeded (yet) in finding extra-terrestrial life!

Humanity 'assumes' alien life needs to breath oxygen, or needs water, that's how stupid we are. The way humanity thinks about this still indicates that we think we're the center of the universe and that how our body's/organs work is the absolute way of all life out there.

[TruthSeeker]

Do extra terrestrials exist?
Considering the size of the universe... yes...

[Winfried]

Humanity 'assumes' alien life needs to breath oxygen, or needs water, that's how stupid we are
exactly what I said!
Humanity assumes it is such and such. Let's go back to the start of life on earth.
In the very beginning Earth had almost no atmosphere. The little bit of atmosphere we did have, was made out of sulphuric acid. First life on Earth thrived on sulphuric acid, deep down in the oceans. This is the big reason why we think everything needs water, our first life began in the water. First Life, however, had a nasty waste product: oxygen. This new gas killed most of First Life, but some bits of it adapted, and started to need oxygen. This was the brink of an atmosphere and after that evolution went quite rapidly. Thus the need of oxygen in all life known to us is explained (sort of).
This doesn't mean it happened likewise on another planet, but it could be so. In fact, why not?

PS: If there are any Intelligent Design-theorists inhere, This is basically how it went, as seen by scientific evidence.

The way you explain it here indicated that oxygen is kind of a drug.

At first, life on planet Earth didn't like oxygen, but when exposed to it, life started needing it and became dependant on it.

Just like drugs, let's say cocaïne. People consider it as bad, but when exposed to it, you start depending on it, because when you don't use it, we get sick and eventually we die.

[Nordac]

That is the basic jist of evolution. Evolution is a natural product of a changed reality, given time time to adapt.

[Anarchistic Fascism]

Nordac, why do you think 'alien life' would look like us, humans?

[Nordac]

I dont think all, but I think some would look like us, because however big the universe is, there are always going to be similarities between things, and life is no different.

[Anarchistic Fascism]

Why can't life be different?

[Nordac]

No! Life is different, but you have things that are the similar, like Humans, and then a human look alike. You could also have reptiles and a species similar to them ect.

[Winfried]

No! Life is different, but you have things that are the similar, like Humans, and then a human look alike. You could also have reptiles and a species similar to them ect.
It doesn't have to be that way. The whole process of evolution on another planet could've gone differently. So there don't have to be creatures that look like us or something we have already seen. But it sure is damned handy if there are.

[Nordac]

Im not saying that they have to look like us, im saying that they could look like us, because their planet changed in a similar way to how ours did.

[Gesiwuj]

People seem to see extra-terrestrials as green as people see aliens as more advanced than us (and they are green as they can make their own energy by photosynthesus) although they may be less advanced than us...

And what about the 'rare earth' theory? What are the odds of a planet being the exact perfect distance from the sun and having a planet as big as Jupiter near us to take all of our comets (plus much more points).

Also, there are some rules that would obviously affect alien's appearances:
- They need a solvent. Earth's solvent is good old H2O although an alien's could quite possibly be another solvent. Their planet also needs to be at the right temperature for their solvent to be liquid.
- They obviously need an energy source, like the chemical energy we gain from food or they could be little green men who photosynthesise. They may even absorb heat or electrical energy - or an energy type we have never seen!
- The molecules have to be suitable complex and will more than likely be proteins. They also need a genetic carrier such as DNA.

Just in case you suspect that your partner, colleague, or boss is a member of an extraterrestrial race, there is an alien test kit (ATK):

Remember: Trust is good, control is better. You could be an alien yourself. :D

The same company also sells one-acre properties on the Moon with Earth view. No joke.

:lol:

Cheers, Thomas

[TruthSeeker]

I have that. My mother-in-law tested positive... :o

[TruthSeeker]

On a side note, I have a few properties in Mars.

No, I'm serious! Just close by here, in Victoria, 20 years ago, the price of land here was around $200 for a small piece of land. Now the same land is selling for more then $200,000! :o

In 20 years, my properties on Mars will be worth quite a bit! :devilish:

[Winfried]

What are the odds of a planet being the exact perfect distance from the sun
Quite good, really. That's the fun thing with Life. It adapts to its surroundings. Though at some point, it adapts its surroundings to it, like humans or viruses.
They need a solvent. Earth's solvent is good old H2O although an alien's could quite possibly be another solvent. Their planet also needs to be at the right temperature for their solvent to be liquid.
For our hypothetic race, it must be a solvent then, which stays liquid at a large variety of temperatures. To exclude as little planets as possible. How I love this kind of science :D

-Let's call them Xhyprezvyx. Just because of the sound of it. Or any other random set of letters.

On a side note, I have a few properties in Mars.
Tell me, where did you aquire bits of Mars? And do you plan to visit your property sometime? I'll be glad to join you :)

[TheObjectiveSubjective]

They probley exist, but even for all the blurry photograpic evidence and so called "Eye wittnesses" we really don't know. They may look like the Grey Aliens, Gery body, large head ,large eyes, thin...but we can't be sure until we have more conculsive evidence.

[sonrisa]

well there's supposed to be bodies (corpses) up at Wright-Patt

[Gesiwuj]

well there's supposed to be aliens at Area 51... at least according to some crazy consipracy theorists who also tell me the moon landing was faked, Princess Diana was killed by local florists, all the world's politicians are lizards in disguise, the masons are secretly controlling the state and that the world started when the evil lord Xenu killed millions with hydrogen bombs. Or maybe the last one was that random church I joined :D

[Smurf]

It was pretty lucky that we actually got one planet that was exactly the right distance from the sun, which allowed correct atmosphere to form and conditions that allowed for organisms to exist. Another planet like ours out there, the chance is pretty slim. Our galaxy is around 80,000 to 100,000 light years in diameter it would take a heck of a long time to actually get to the extra-terrestrials if we ever found them. The chance of discovering aliens is extremely slim aswell, I mean we are basically randomly searching parts of space for them - no particular pattern, just pointing the dishes out to space and crossing our fingers.

[Winfried]

Theirs a quote of a famous Dutch comedian I would like to put here (translated of course, for those who don't understand our beautifull language): What's with this search for Extra-Terrastrials anyway? They are either smarter than us, or less smart than us. If they are smarter than us they will probably find us first, and if they are not, I wouldn't like to meet them.

And then goes a rant at bush, who seems to be one of them stupid aliens... :rolleyes:

[Smurf]

Yes I thought Bush was acting strangely?

What if we are completely alone in this universe (probability suggests otherwise) but we are the only "beings" here, one chance

[sonrisa]

Winfried-- then goes a rant at bush, who seems to be one of them stupid aliens.. :blink:

Smurfie-- Yes I thought Bush was acting strangely?

-- it would explain alot....

Gesiwuj-- well there's supposed to be aliens at Area 51...

-- scroll down to q 23 on Wright Patt's FAQ page.... (click here) (http://www.wpafb.af.mil/faq.html)

:D

[abaris]

Bush is definitely an Alien. Have you noticed how he pauses in the middle of a sentence?
He does that every time the mind-link to the hive is disrupted by solar flares.

[sonrisa]

"mind-link to the hive..."

so you think he's a wraith then?

[Smurf]

^nahh he's definately a Zerg in disguise

Bush is definitely an Alien. Have you noticed how he pauses in the middle of a sentence?

:lol: Yes!!!!

[abaris]

mind-link, hive-mind, isn't it obvious: i'm saying he's an LGM

Like this?

[abaris]

yeah. Only less cute, kind of evilish and without the third eye.

[Smurf]

yeah :lol:
anywho

I got talking about this on another forum and one person discussed that perhaps there are aliens that could live in extreme conditions, humanoids that could live on methane worlds? Something like that, I argued that it takes a long time for just us to be here through process of evolution so what about them?

[sonrisa]

each planet would have it's own evolution, specific to that planet.

so yes, you could have life forms that breathe methane instead of oxygen on some other planet. In particular, for there to be life on the outer planets.

[CSwriter1]

Is there agreement that physics is uniserval law? A triangle on earth, is also a triangle on mars. The laws of motion and gravity are the same everywhere. Conditions can vary, but not the laws.

Life forms are a matter of math, and physical and biological laws. I think it is unimportant if there are different minerals, plants or animals on other planets, but that alien life such as ourselves is important, because of the consciousness factor and ability to move and manipulate the environment. I would expect such life forms to have evolved by the same laws governing our own evolution. There may be some variation, as there is variation of humans on earth, but basically this being, would be as ourselves because the laws that make us as we are, are universal laws. It is a mathematical design.

I think it is possible there are other beings in the universe, and that they colonized earth.

Of course! Beings are numberless!

[Winfried]

This is my return after being away for a pretty small number of weeks.
And I'll start off with a very obvious comment.

Whenever an astronaut is in space, there is at least one extra-terrestrial. For he is "outside of the earth".

How I missed saying this kind of things. :lol:

[______]

Clever! :lol:

But on extra terrestrials from another planet a.k.a another intelligent species + God.... (must.... divert... from religion.... in.... a science..... topic......)

....Christians state that God created man and man alone. What happens to this theory when/if man comes across another intelligent lifeform on another planet? (No! :duh: Another topic all together!)
