Do Aliens Exist!?

[PK|Hexx]

What is your opinion is there aliens out there in the galaxy or even among us - like ames hes an alien, post away

i think , that to think aliens exist is normal because there must be other planets out there which have developed like earth.

[PK|Colonel Ames]

I think it is just plain ignorant and arrogant to think we are the only intelegent life forms in the whole universe.

If space goes on forever, then it is impossible for there not to be another world somewhere out there with civiliastions.

and besides, like hexx said, were do you think i came from?:luke3:

[PK|Lemming]

Space is infinite (no limits)

as not every planet will be capable of supporting life, there are therefore only a limited number, infinity when divided by any finite number is always 0

therefore there are no aliens, as there is no life at all in the universe.

[PK|Hexx]

rather bleek way of looking at it m8

[PK|Cerro]

hmm lemming, thats a very cold mathematical way to look at it. The universe is massive and ever expanding, to think we are the ONLY living beings in the universe is somewhat hard to believe! If we are the only sentiant beings then its an awful big waste of space!

Besides, planets like Mars were once able to sustain life - who is to say we are the only ones that exist (or have/ever will exist). I'm sure a dinosaur would have laughed if you'd told him they'd all die out and those puny monkeys would rule the earth in their place. That's just on earth... never mind the other billion or so galaxies out there! If there is life out there, its probably much smarter and older than us and the distances involved mean the chances of a random encounter are almost nil.

And hexx, you listen to the radio too much... just cause everyone's favourite crazy scientologist (Tom Cruise) says he believes does not mean you should follow him (or that crazy 'religion' that he follows).

In other news, £600,000 given to a skitzo sexually abused by a catholic priest for 10yrs. Amazing how easily it just hands out £600,000 in an out of court settlement - religion's are not for profit at ALL are they?

[PK|Soleft]

We are aliens on Earth apparently, life started too early. So a theory approved by so and so (I forget names) said a met hit Earth and the bacteria on it, yada yada ya. You get it. There is def life out there.

[PK|Solid_Snake]

or mebbe we've elvolved out of phone cleaners and heir cutters , and we wiped out the original lifeforms :)

[JoMo]

the maths is wrong, infinity/number = infinity therefpre there is an infinite chance of there being oher life. however the physics is wron there, The universe is not infinite it is ever expanding, an once you reach the end you curve back round to the beginning. there is not an infinite amount of matter(otherwise that would bugger the law of conservation mass energy) so the possibilityis not infinite but rather finite, so who knows.

[PK|ReUsed]

I believe there is a planet vulcan that watches over planet earth... and one day when we discover warp drive they will arrive on our planet with a message of peace to make first contact... all this will be the start of some sort of... intergalactic federation of planets.

[JoMo]

oh my god, I saw this documentary about that once....

[PK|Cerro]

actually Jomo the universe is beleived to be flat and ever expanding, until recently it was believed to be curved and that someday the universe would fold in on itself, but that will never happen, as the universe is flat (or flat in a non-curved circluar sense)... in esscence, lemming is correct - the universe is infinite but i still do not beleive that we are the only living intelligent life in the universe.

[PK|ReUsed]

if it's infinately big and it's getting bigger, how bigger will it be in a year? infinate + more?! im confused, isn't infinate the end of everything? apparently not, cause it keeps getting bigger?... if "infintate" was even bigger than that, wouldnt less infinate not actually be infinate?? someone help me plz.

[JoMo]

cerro, still just a theory my friend, thats just one of the newest ones, but going on that principle, how can a space that never ends get bigger? plus the amount of matter in the universe is not infinite. And even if it is, Infinity/finite number still = infinity, therefore if the universe is infinite (which it isn't) aliens exist, along with every single other physically possible thing.

Reused infinity isn't a number its an idea, but infinity is totally irrelevant to this discussion, the univese being infinite is an ancient theory which has been disregarded a while back.

So in conclusion it is impossible to mathematically prove aliens exist as the universe is NOT infinite, and there is a finite amount of mass inside. so everyone stop trying to say the universe is infinite.

and specially for reused, infinity is not a number, imagine this, you travel infinity miles towards the edge of the universe, when you get there you travel another mile, after that mile you've still travelled infinity miles. same goes for all mathematical operation(+,- etc.), however i'm not suer about infinity/infinity or infinity - infinity as those by laws of maths should = 1 and 0 but im pretty sure they still = infinity(damn I wish I could be arsed to copy paste the word infinity)

[PK|Hexx]

how about this, what if our universe is a planet in an even bigger universe, that could keep going, or men in black with orions belt etc

[PK|Lemming]

i got my sum the wrong way round, something divided by infinity is 0.



dammit, its been a long time since i went to school.




c&p from bbc.co.uk

In astronomy, the density of the Universe goes under the symbol Ω (or Omega), the last letter of the Greek alphabet, meaning 'the end'. The precise amount of matter needed to gradually halt the expansion of the Universe is known as the critical density, where Ω=1. If Ω is 1 then the future of the Universe is a gentle, serene stop. Smaller than 1 and we're heading for the quick Big Freeze, a universal ice age. Larger than 1 then it's Crunch time. So our destiny depends on our density. Recent results show that Ω is at least 0.3. That figure includes the mysterious dark matter that lurks invisibly in space and has yet to be fully understood.

[PK|Cerro]

ok.... i guess that means the universe will go through an ice age at somepoint then, in which case all life is doomed (but thats a sad fact of life, however you look at it).

But the universe will probably go dark someday, when all the stars die out - how many new stars do you see every night? then again that will take several billion years!

[PK|Lemming]

the whole quick freeze thing, is based on stuff is accelerating away from other stuff, thus forming a flat limitless universe (this is where the "the universe is infinite" comes from.)


i think NASA have some understandable stuff about this on thier site

[PK|Soleft]

I agree with Jomo

[PK|Cerro]

hmmm in that case lemming you are correct but we are still talking billions and billions of years before things like that become even noticeable. Im pretty sure our galaxy is suppose to collide with another galaxy in several billion years, however scientists seems to have trouble predicting where meteor's will go, nevermind a billion year calculation on where a galaxy is going to travel...

But moving back to the actual point of the thread - just because things spread out or because there is a limited amount of matter in the universe does not mean we are the only living things in the entire universe - we don't even know what other galaxies contain, nevermind our own!

I think its abit presumpious of humans to assume we are the only intelligent life in the universe - in which case we'd be freaks of nature, never meant to happen. And then there is nothing preventing us from creating our own forms of life in the future...

[PK|Hexx]

thats the thing isn't NASA pay tons of scientists billions of dollars to predict (guess) what will happen to the universe, We will be dead before anything happens to us after all.


unless the big freeze is set to come in, in our lifetime in that case we better dig ourselfs down to the center of the earth

[PK|Lemming]

heh. i think u kida missed the point i was making


the universe is infinately big
the number of planets is small

big/small ~= 0


there is no life anywhere in the universe, we are merely a statitiscal anomoly & can therefore be ignored


seriously tho, there is bound to be some sort of lifeform elsewhere in the universe, whether its advanced and/or intelligent or not another discussion.

[JoMo]

I do think there is life on other planets.

[PK|Hexx]

it would take some kind of miracle, because if you think about it our planet is in exactly the right setting to produce life, ideal distance from sun, which is what it boils down to, too near the sun = to hot, not to mention one half of the planet would be in habitable in the day and inhabitable at night because it would be too cold... and those planets which are too far away from the sun will just be too cold to sustain life, and no life would not evolve, because there would be no life to evolve from :D

then again there are so many stars out there and so much distance that the possibility of another planet being the right distance from the sun is actually probable, which is where the idea of an alternate reality comes in

[PK|Cerro]

like i said, mars could once sustain life, these things change... and now its barren. Earth will probably one day go the same way if something doesn't do it first or if we do the job first!

Plus hexx you forget that not all planets rotate at the same speed as us some barely rotate at all and so its possible for one side of the planet to be in near dark the whole time, the other to be bathed in a sun's irradating glow... there's a bit inbetween too!

[JoMo]

plus who said life can only come into being in these circumstances, bacteria live in the kind of circumstances you're talking about. Just because we can only survive in these conditions doesnt mean other lifeforms can. bacteria were, at first, not be able to survive temps of over 100 degress, this has been proved wrong. Life does not need pure oxygen either, it needs some source of it, or non-atall, if planets with those massively heated sides covered in radiation had life the life would be evolved to deal with that but it could also use that as an energy source getting ir dof the need for eating or oxygen or an atmosphere, a living solar panel

[PK|AvP]

i dont uderstand y ppl dont believe there are aleins in the universe as 1 or more sed (cant rember who) the universe is infinate so there must be some thing out there... and 1 of u sed humans were intelegent (cant spell oops proved a piont) were not coz if we were the world wouldn't be collapsing from the inside out coz of all the green gasses and shit so humans are STUPID.

[JoMo]

once again, THE UNIVERSE IS NOT INFINITE!

[Jenni]

there might actually be an answer to this, i just cant be arsed to look it up (and please dont take this as a dig at you but...) how do you know?

[PK|ReUsed]

maybe the universe is like a pancake, where theres like 4 of them all on top of each other... and some people cook them and then put butter on it and some mayple syrup then eat them for breakfast. And other people make fake universes with holes in them and try to pass them off as pancakes when they're really crumpets which taste like balls.

then again, maybe not.

[PK|AvP]

Im sry reused but that was more random than wat i normaly write im sry but WTF were u on about????

[PK|Lemming]

once again, THE UNIVERSE IS NOT INFINITE!

according to the current theories it is m8.

as stuff is accelerating away from other stuff, it points to the theory that the universe is flat,

the theory kinda works like this

If you start from a fixed point A, and travel in a perfectly straight line

in a Curved (finite) universe you will return to A
in a Hybid (saddle) universe you can eventually return to A
in a Flat (infinite) universe you will never ever ever see point A again, EVER.

[PK|Hexx]

i can understand what reused is on about completely, but i must mention don't forget about the criossant universe's which get chucked in the bin for being french

[PK|Mojo J-Lo]

Yeah, I like Einstein Saddle universe...The others are to finite for me. And I don't like the idea of everything in the universe being crushed and starting again.

(I've never got the whole shape thing...I just think about it like so: if something has more kinetic energy than the gravitational energy acting on it from the center of mass of the universe...it goes backwards. Less and it goes on to infinity. Equal (equilibrium) and the universe slows down and slows down, getting nearer and nearer to the balance point.

And the universe has to be Finite with the big bang theory... You had matter at a point...travelling at a finite speed, for a finite length of time (Means finite distance).

[PK|AvP]

erm i thought the post was about aleins and i do understand y and ho we off track can we swing back to the aliens i wonder wat theyed look like erm.......mabye they would look like cerro or is that a bit harsh on the aliens there duno??? lol

[PK|Solid_Snake]

i can understand what reused is on about completely, but i must mention don't forget about the criossant universe's which get chucked in the bin for being french And the crumpet universe too because it shares the nationality of the guy who posted the non sense thats quoted, it gets stuck down ur throat and never ever goes down of back up EVER, causing a lethal choke to the poor person eating it. : p

criossant is spelled croissant :P

[JoMo]

this is precisely about aliens, its about one proof of why aliens exist. if the universe is infinite(which it is not, it just isnt) then there is infinite possibilities whihc obey the laws of physics one of these possibilities is life. therefore this is totally on track and more on track than your post as it is not about aliens existing but about aliens.

[HovisBread]

Meh us humans are far to stupid to ever be able to understand the universe, we're just arent clever enough, darn it! :(

[PK|Mojo J-Lo]

Maybe as a hive mind...each person holding a little bit of the knowlege we may one day have an understanding of the universe...why we'd want to understand it so much isn't that obvious though.

[kamikazied]

it has taken 4500 million years for us 2 be here, and if u where to look at a clock we've only been here less than 60 secs on that clock there could of been civilisations on our planet wiped out along time ago, yet we're still here. chances are there is something liveing out there other than us. be it acid based or alkaline based life form. could discuss this subject for ever!

[PK|Mojo J-Lo]

Yes, just cause the universe isn't infinate doesn't mean there isn't life. But if there was other life the chance of us reaching it within any of our lifetimes is slim...and if we did, would be be even close to understanding them.

[PK|Hexx]

But, do aliens exist!?

[PK|ReUsed]

i think the answer to that was "maybe".

im agreeing with jomo that if the universe was truely infinate there'd not only be aliens but there'd be infinate humans on an infinate amount of "earths" as well that have lived the exact same lives as us...

to be honest that sonds rather absurd... the idea of a nearly infinate universe i can comprehend and that it expands only so far, but anything else is just silly.

but to quote myself on an earlier post, "I believe there is a planet vulcan that watches over planet earth... and one day when we discover warp drive they will arrive on our planet with a message of peace to make first contact... all this will be the start of some sort of... intergalactic federation of planets."

[PK|Hexx]

lol :), or as soon as we discover warpdrive the vessel crashes into an alien battle cruiser and the aliens ATTACK
