• Is it possible that Earth is on the edge of the universe away from all life?

    Honestly, this is what I think, because if life has existed elsewhere, why hasn t it made its way to our planet, is it because we are so far away from any inhabited planet that even planets that HAVE mastered space travel still can t make their way to our planet? Are we just tucked away? So well concealed we can never be found? By anyone?

    Looking out my window, right now its exactly 5am on september 9th 2013. there's a bright star (and NO its not a plane, i've been watching it for almost 2 hours), and its slightly moving, almost spiraling. like its out of control? i dont know, but its definitely a star. but i looked up to see the dates of falling stars, i'm not knowledgeable in this kind of stuff, but i'm wondering if this is a falling star/meteor or somthing. please help ? FYI to the person who said this, "It is not a meteorite. These are just a streaks across the sky, rarely lasting for more than a couple of seconds. It is not a star if your description of it's movements is correct. It is not a comet because there are no comets visible to the naked eye in our vicinity. You are probably seeing a satellite reflecting the light of the Sun, though these usually show an appreciable movement in a particular direction unless they are in a geosynchronous orbit. There are quite a few of these objects orbiting the Earth, so this may well be an explanation for what you observe." Please Re-read my description. I said I was watching it for 2 hours. So what you said cant be true. A couple of seconds? Then, why have I been watching it for a few hours?
