Nirth: The problem with this line of thinking is that it goes like this "because it should be, it ought to be" or something like that. While the hypothesis that aliens might exist has the argument that it's less likely that we are the only intelligent life out there because of the size of the universe it's still possible that we are alone.
And no, we do
not know we are not alone, it's
probable that we aren't but we don't know. ;)
keeveek: I am not a physicist, but I know a few of them, and they always told me "if the possibility is bigger than zero, it
happens right now somewhere in the universe.
And if the universe is infinite, then you may be 100% certain that there is a life somewhere outside solar system. :)
I happen to agree with you. But they (the scientists) don't believe that the universe is infinite anymore. (And yep, I've noticed your IF, so don't worry =) ) Some are trying to prove this by explaining why all the matter in our universe is accelerating instead of slowing down. There should be something in the "edge" of the universe pulling matter faster than our own gravity here can contain it. Until recently, they thought all matter in our universe were slowly decelerating (due to gravity) now they know it's the opposite and they can't explain it if the universe is infinite, so, they changed the rules. Some of them think this is due to another (perhaps bigger) universe besides our own.
I recommend anyone interested in this to research the topic: String Theory.
KneeTheCap: Well, I believe in "ghosts" and paranormal. Why? Because I have my own experiences. I'm not expecting you to believe me, you are free to draw your own conclusions. You can also try to explain these to me.
1. The night after my uncle died, I suddenly woke up and saw a bright white floating orb right in front of me, it then let out a sound and descended through the floor. It was bright but it did not illuminate the room. Hallucination? Perhaps. But do explain to me why my wife saw the same thing the night after my father died? These happened two years apart from each others. I did not tell my wife what I saw back then, but I was totally startled when she told me her experience. White glowing orb that did not illuminate the room. Coincidences? Perhaps.
2. After my uncle died, we went to his flat (which is located about 30 meters from our house) and cleared the fridge from food and cleaned the place up. We left the fridge door wide open, unplugged. The next day we went back to finish the cleaning, the fridge door was shut. No, it does not close up by itself, as the fridge is slightly tilted, so the door would move away from the fridge. Nor does the "breeze" close it when we close the main door with haste. We tested it, didn't do anything.
3. We all went to my father's funeral, and when we got back, my other uncle (who lives next door, some 100 meters from us) noticed that his makeshift fence's door was... upside down. No one was home. I didn't see this myself, but I have no reason not to believe him.
4. My aunt told me that after her father died, she and her sister heard his voice the following night, with footsteps and a door opening. She claims that he had said "and there they live" in Finnish. She went to check, and saw no-one.
You can choose to believe me or not, but I stand by my words. I have no reason to lie to you.
Pretty creepy stuff.
I don't have any reason to doubt you, nor have the passionate desire most people have to either curse you or believing all of this is real. That being said, while I'm skeptical about this kind of thing, I cannot explain some events in my own life as well. I don't think we (humans as a whole) will ever be qualified to answer all this questions. My guess is this planet is going down (one way or the other) long before we achieve this knowledgde.
So while I don't doubt for a second you (and those you know) really saw/heard something, I'll always try to find another explanation first before blaming the supernatural for it =)
