whos to say we exist? Maybe we are all just a frigment of your imagination. Or maybe theres a civilisation on another planet asking do we exist?

Ouch.. my head

ancientdog

yeah sure we exist. thats how you know aliens exist.

Spastafarian

I'm sure they do but it doesn't really matter cos we'll never meet them.

According to Chris De Burgh Jesus was an Alien. Chris De Burgh is a wise wise man.

ah we may meet them someday, they exist, jesus said they do..lol

grimes, jesus wasnt the alien, a spaceman came travelling to see jebus.

The drake equation is pure conjecture, as pointed out in the wiki article.

ParkRunner

There are some people on this planet who don't quite comfortably fit into the category of human beings, but we still manage to co-exist.

dsmythy

I think there is a good chance they do exist. I don't think they've ever been here though.

Well its criticised, in the generic 'Criticism' paragreaph.

No reason to dismiss it tbh. Is there a more acclaimed and backed equation for estimation?

Of course 'aliens' exist. It's just absurd to think that a universe the size of ours would only have us in it.

I don't think we have advanced far enough in science to rule out their existance. it's pretty much personal belief at the mo

I'm sure four of my children are from another planet...

course they exist. Loads of illegal aliens in ireland sure

Yes, to think we are the only ones in the known and unknown universe would be far too presumptuous and big-headed.

IvySlayer

I'd like to think that on another planet there are aliens doing their thing. The Universe is massive. There's gotta be SOMETHING alive out there.

I bet the folks on the planet Zetaqriuy are asking the same question.

No. The Drake equation wants to claim that life is plentiful, but also wants to explain why we dont see it ( i.e. get the signals from a technological civilization) be adding in an equation L, for the length of a civilizations ability to broadcast signals - guessed by Drake at 10,000 years. Thats absurd, in fact any civilization that became intersteller would probably produce signals from then on in... in no way could the civilization collapse so that it forgot how to create electromagnetic radiation unless every single constituent parts of the civilization were destroyed simultaneously.

The question, isnt about aliens. There may be bacteria. But intelligent life at a technological level. If its there, where is it?

It was broadly similar to ourselves 10000 years ago. It has evolved, much as we are now, to a lifeform that consists of a large mouth for the injestion of large quantities of alcohol and sugar, a large stomach for the digestion of same, 2 large eyes, to digest the endless re-runs of their Big Brother, and a tiny brain. They're not interested in looking for us, just a cure for Diabetes.

the wow signal was just from a television set in mexico or something.

I know you are being funny, but nevertheless :-) remember we are a young species. There should be alien lifeforms with technologies far greater than ourselves - millions of years old. It could be that technological societies are rare even with intelligent lifeforms, or that earth planets are rare, or that life isnt certain on earth planets, or that the evolution of life is chaotic and we are a monumental fluke. Most Earth like planets probably have donosaurs, or something like it.

The only reason this planet is dominated by mammals is the sheer ferocity of the collision which wiped out the dinosaurs. That may be a cosmic fluke. In any case the first dominant species on this planet was never going to be intelligent.

In terms of space exploration we are at a level equivalent to the 15th century. Just because we do not posess the technology does not mean it isn't there.

The_Minister

There is most likely other forms of life out there, however, it is very possible that none of it is intelligent, and almost certain that it will never contact us if there is.

well horse

Yes, they definately exist. All we are, ultimately, is a chemical phenomonon on the face of this planet.

The idea that such a phenomenon has never arisen blindly on another planet with the correct enviroment etc seems higley unlikely, given the sheer size of the universe.

And as The Minister says above, it need not be intelligent life as is familiar to us. It could just be some sort of very simple but self-perpetuating bag of chemials that can reproduce.

The_Minister

Also it should be remembered that "intelligence" as we see it will not nessacerily lead to a high technology level.

Most of our own existance has been without the ability to control electricity or build machines. Out of over 100,000 years, we've only been really advancing for about 9,000 and only had signals of the kind that would let others know of our existance for less than a century. It is very possible that other creatures exist, but will not follow our route of discovery.

Similarly, any creature in the wrong atmosphere (water-dwelling, or with air with the wrong composition), would not be able to discover fire, and so all our innovations would be impossible.

Also, if you read this wiki article you will see that the conditions nessacery to support our kind of life are very rare and precise.

asdasd

so the answer to the thread is:

Yes.

And, no.

asdasd

Also it should be remembered that "intelligence" as we see it will not nessacerily lead to a high technology level.

Correct, the Enlightenment, and scientific revolution, seems an aberration even in Human history.

complete waste of time, scientists are after recently finding out that once signals leave our solar system they become nothing more than indiscernible noise so signals coming from other galaxies or even other solar systems within out galaxy would never get close to reaching earth. unless little green men are living on pluto or saturn we can forget ever receiving signals

just a few numbers
*earth is 26,000 light-years from the centre of our own galaxy

*the nearest star to our solar system is 4.2 light years (just for laughs it would take a conventional rocket approx 90,000 years to travel that distance at a constant speed of 50,000 km an hour)

*between 200 and 400 billion stars in our tiny galaxy (which measures about 70-100,000 light-years across)

*there is between 50 and 80 billion galaxies in the known universe

We'll never fully know unfortunately, although I'd love to think there are Lidls and Aldis sprouting up on planets hundreds of lightyears away

i think that if they do exist..... it would probly be somthing as small as a single cell organism and wouldnt be nearly as advanced to have flying saucers.

Quite correct if your still thinking along distance and dimension as humans so far can measure it.
However if a further more advanced species has/is taking advantage of travel along other lines such as folding dimensional/inner-dimensional travel alone then conventional travel and speeds as WE know them goes out the window.

Generally speaking, the idea of dimension/hyperspace travel relies on the existence of a separate and adjacent dimension. When activated, the hyper drive shunts the starship into this other dimension, where it can cover vast distances in an amount of time greatly reduced from the time it would take in "normal" space. Once it reaches the point in hyperspace that corresponds to its destination in real space, it re-emerges.
In other words, some (or all) paths in hyperspace may have a travel-time less than the time it takes to traverse the "shortest-path" in normal space, defined above. The time it takes to travel in hyperspace is measured in the same way time is measured in normal space, unless the hyperspace is discontinuous. For example, the path in hyperspace may not be smooth but a sequence of points, and the time change from jumping from one point to another may be abrupt. In this case, add the time jumps. Some may be positive (jumps to the future), and some negative (jumps to the past), depending on how the hyperspace is defined.


Explanations of why ships can travel faster than light in hyperspace vary; hyperspace may be smaller than real space and therefore a star ship's propulsion seems to be greatly multiplied, or else the speed of light in hyperspace is not a barrier as it is in real space. Whatever the reasoning, the general effect is that ships travelling in hyperspace seem to have broken the speed of light, appearing at their destinations much more quickly and without the shift in time that the Theory of Relativity would suggest.
In much science fiction, hyper drive jumps require a considerable amount of planning and calculation, with any error carrying a threat of dire consequences. Therefore, jumps may cover a much shorter distance than would actually be possible so that the navigator can stop to "look around" -- take their bearings, plot their position, and plan the next jump. The time it takes to travel in hyperspace also varies. Travel may be instantaneous or may take hours, days, weeks or more. Some theories state that a route traveled for a long time may continuously stay open.


A different concept, sometimes also referred to as 'hyperspace' and similarly used to explain FTL travel in fiction, is that the manifold of ordinary three-dimensional space is curved in four or more 'higher' spacial dimensions (a 'hyperspace' in the geometric sense. This curvature causes certain widely separated points in three-dimensional space to nonetheless be 'adjacent' to each other four-dimensionally. Creating an aperture in 4D space (a wormhole) between these locations can allow instantaneous transit between the two locations; a common comparison is that of a folded piece of paper, where a hole punched through two folded sections is more direct than a line drawn between them on the sheet. This idea probably arose out of certain popular descriptions of general relativity and/or Riemannian manifolds, and may be the original form from which later concepts of hyperspace arose. This form often restricts FTL travel to specific 'jump points'.

Long story short - distances as WE know them now are only limiting us according to our PRESENT day knowledge and available technology.

Depends whether you're a Scientologist or not eh?

And in fairness, it would be hugely arrogant to assume we're the only and most evolved intelligent life form when we don't really know all that much about the rest of the universe. Hell it could be so infinitely vast that we never do meet "them" but it's kinda cool to think that somewhere out there there might be people/things pondering the very same question.

midlandsmissus

They definitely do exist and they definitely are here.

I'm surprised no-one on here so far has said they've seen anything.

Myself and a huge group of people saw a flying object one night in college that terrified the bejeesus out of me.

My whole village saw a very strange spinning disc fly very low one day.

Wasn't there a ufo seen by a load of people in meath recently? Look at all thousands of people who have seen things that alude to other planets visiting here.

Also theres a video on youtube where a canadian government minister admits the presence of aliens on the earth, and also admits to the huge cover up america decided to do,it's very interesting.
