Who here has ever seen an alien?

[Jackolantern]

why does an alien have to travel @ x amount of light years just to come see us... they could live for thousands of years for all any one knows. one day to them could be several years for us. and it doesnt have to be a 'leasure trip' lol. you think how long some people spent traveling around the golbe in search of new places. before plane n things where invented.

christopher columbus didnt think about exploring but decided nto to just because it would have taken more than a day or 2 lol. Think of all the poele who go travelng to see new places. they can spend years doing so.

people who have flown to the moon, didnt go there n get back after a couple of hours lol.


and time travel is possable... travel to a different country and you travel in time (relitivly speaking) because of the time differences :p

I have thought of that as well, but it has some holes. If you can't travel the speed of light, we are talking about huge amounts of time. Even for yet unknown alien beings, it would be astounding lengths of time. The nearest galaxy to our own is Andromeda, which is over 2 million light years away. Even if we give them 2x faster travel than what we have, that would be somewhere over 2 billion years. It of course is possible that it could come from within our own galaxy, or an outer cluster, but if they are moving that slowly, why couldn't we pick them up coming in. They would have to be quite small to make it in without ever showing up on any radar. Plus, I can appreciate differences in time, but man...no matter how old you live to be, you would have to feel thousands of years passing and feel like you are wasting your time at some point.

EDIT: And I meant "leisure trip" as being somewhere under 100,000 years lol I know, sarcasm on the internet... lol

dont forget worm holes.

I guess it is possible, but that is just one of those things we don't have a shred of evidence to support or disprove.

[Last Known Hero]

For all we know, they could travel at 10x the speed of light, each could live to be 10 000 years old. We can't prove it or disprove it. Some people have seen them, some people haven't, I'm not calling anyone a liar but what is possible for them may be impossible for us. Their anatomy could be capable of withstanding different effects than us and they could theoretically be physically able to travel faster (i know that it is still 2 million years away). Or they could have been in our galaxy this whole time.

With how much we know, it is almost impossible to argue..

[hallsofvallhalla]

true since only the government has disected one only they know. hahahaha j/k

Aliens exists, its ridiculous to say they don't, i just cant see how in the sheer vastness of space that we can be all alone. Not sure why they would vist earth though? also we might find life on mars in the form of bacteria which would be cool

They found life on Mars in the form of bacteria, although it was fossilized, but the fact remains, its there!


I personally believe if they exist close to use, the closest planet to us is Alpha Centauri. It has two suns, one of which is about the age of our sun, shows all the same characteristics of our sun, plus there is a planet orbiting close proximity as how ours orbits as far as distance. They believe (though cannot see it yet) that the planet maybe close to how Earth is, and may support life.

But thinking outside the box, who is to say that Aliens have to live in the same type of characteristics of Earth? Life can form anywhere, so why cannot life form on a volcanic world, or an ice world. Life is not predictable, and one cannot say that they have to match Humans/Earth or they cannot live.

Don't forget Proxima, the third star of the Alpha Centauri system! However, no planets that I know of have been found in Alpha Centauri. Because of the light emitted by the two major stars, we have no way of viewing any planets even close to Earth size there. They would have to be on the magnitude of Jupiter or larger to have a noticeable "wobble" on the stars during orbit for us to detect them, such as how Fomalhaut b was first detected before being photographed in visible light spectrum (don't get excited, it is just a tiny red dot, even though it is still interesting). What is actually quite exciting is the rebirth of the idea for using nuclear pulse propulsion, such as in Project Orion, to launch unmanned vessels to other celestial bodies. Alpha Centauri would be an obvious choice since it is so close, at 1.75 light years. Current technology would take us about 2,000 years to get a probe there, which is basically pointless, but some at NASA thinks an NPP probe could get there in a matter of decades.

And about life having different forms, I was actually just thinking about that yesterday. What if one day we went to an extra-solar planet and found tiny buildings with little moving, sentient rocks living inside them. Like you said, we can only guess what shapes life can take by what is on our planet which basically means we have no clue.

Ok, I quoted that wrong, not found a planet, they ran simulations regarding that trinary star system. http://www.sciencedaily.com/releases/20 ... 121613.htm Basically if there was a planet there, it would be much easier to detect because of the three suns. Each time they ran this computer simulation different planets formed, but always one formed in the "habitable zone."

Also Alpha Centauri is 4.37 light years from Earth, or 1.34 parsecs. http://en.wikipedia.org/wiki/Alpha_Centauri.

Though it would be neat to learn there are hundreds, no thousands of different species in the galaxy, of all shapes and sizes! I for one look forward to the day, the first race out there, announces that we are not alone!

[Jackolantern]

Oops, got my numbers mixed up lol. Well, that changes things then. It would take current technology about 5,000 years to get a probe there. And yes, that simulation on A. Centauri was interesting, but I had read that it would actually be [/i]more[/i] difficult to see a planet in the inhabitable zone in A. Centauri due to their stars. Well, it would be almost impossible to see planets in any system's inhabitable zone with current technology, but since one of the stars is so young (like our Sun, as you said) it is giving off massive amounts of light. Even to the Hubble Telescope, the distance between an A. Centauri star and the inhabitable zone is like a grain of rice's distance, and the light radiating from the stars just makes it too bright to pick up the speck of dust that would be a planet. And since there are no planets big enough in Alpha Centauri to noticeably affect orbit and planets don't emit traceable radiation, we really have no method to discover them today.
