I'd say the chances of there NOT being other forms of life SOMEWHERE in the universe, which is HUUUUGE, are pretty slim. The same conditions that occured on our planet must have occured on some other planet somewhere. Those are my thoughts. Permalink
I believe there are aliens. But, I just hope they won´t come too soon. You know what happened on earth every time a new continent has been discovered and colonised!? The indigenous peoples were mostly not the fortunate ones... Permalink

That's what Hawking has been saying. Even if they're not malicious, just them breathing on us could spell disaster! Bantha breath, yikes! Permalink

I dought they would do that if they were intelligent, and not malicious but yeah they could breath our air and exhale toxic gasses, like cyonide. I do belive in aliens but dought there would ever be any that have the technology, and live close enough to us to visit. I think there are huge chaces of there being bacteria, and slim chances of there being animals, at least near us. I think there must be speices out there with advanced technology but to travel so far for so long a time to visit earth seems like impossible odds.
I bet if they were like us there would be a good chance that they would destroy themselves before getting to that level, I mean look at us, we came close to destroying ourselfs a few times. I think its pretty safe to say aliens have never visited us, and wont in our lifetime. But if they are super advanced, and have the technology to travel through space quickly, then it would possibly be common for other sentient life forms to have visited each other multiple times. If they do have such a malicious attitude I would think multiple wars are being fought right now. Permalink
WHEN aliens are discovered and IF they visit us,I hope they dont mirror my novels versions. One is friendly and helpful, another is fierce and destructive, the third is intelligent and insidious. Permalink

Well, if you figure the Universe is approximately infinite and there are approximately infinite parallel Universes, I'd say there are approximately infinite life-forms out there.
The Hitchhiker's Guide to the Galaxy has something to say about this. The population of the universe is a finite number. The size of the universe is infite. To get the average population of the universe, divide its population by its size. Unfortunately any finite number divided by inifinity is ZERO and so the average population of the universe is ZERO. Therefore anybody who you meet is just a product of your fevered imagination. Permalink

Haha, yep! ;) I bet there's some formula to figure out the truth though, like an advanced calculus. Permalink

Of course, we all know the Aliens are already here. And we're they! You know, when the BSG fleet arrived here 150K years ago...
Are you sure about that? According to Douglas Adams we're all descended from a group of telephone sanitizers, from the planet Golgafrincha, who must have arrived at about the same time as the BSG crew. Permalink
I used to not believe, but now I do. And I use the same argument for both viewpoints.
Life has to me made of something. for us, that something is elements heavier than hydrogen. The galaxy is about 74% hydrogen, 24% helium, and all other elements are 2%.
In any given galaxy, there are two variables that determine where life can arise:
A: radiation. The closer to the galactic core you get, the more stars, and the more radiation. Life cannot arise in the core because the molecules are always too hot and getting hit with high energy particles.
B: elements heavier than hydrogen. The closer to the core you get, the more heavier elements there are. At the galactic rim, there are not enough heavy elements to make planets and living things out of. But if someday some stars fuse enough heavier elements, the rim would be a fine place to live.
This ends up making a doughnut shaped habitable zone in a big fat ring around the galaxy. The place where there are enough heavy elements to make life out of and not so much radiation that they are always irradiated.
Within that big doughnut, find every star. Each has a habitable zone around it, a smaller doughnut. As a proportion of the galaxy, the habitable zones around the stars is minuscule. Now for life to develop in that system, there must be a planet orbiting within that habitable zone. That planet must be more than a big rock. It needs to have a Van Allen shield around it to protect organic molecules from solar radiation. That limits the search to planets that are made of iron and large enough that the planet's gravity presses down on the core and keeps it molten. Otherwise you get a dead rust ball like mars.
Given what we used to know about exoplanet, I would argue against there being life on other planets. but given the numbers of new planets we find each year, I argue that somewhere in the galactic habitable zone there is a star with planets of the proper size and orbit. Permalink
I've seen a UFO before. A few years ago, I was in the car and saw some flashing lights from the sky. When Iooked up, I saw a huge triangular UFO in the sky with flashing lights coming out of it in all directions. Couldn't take a picture because I didn't have a camera or phone with me. I know this is hard to believe, but I am telling the truth. Permalink
