i for one do believe that there are other life forms out there, i mean witht eh abundance of systems like our own, there is no doubt that ther eis another earth style planet out there, wether they look like the aliens people say with big black eyes and green bodies is questionable. But the fact that the universe is so big i extremely doubt we are alone in teh universe, i mean just think every star you see has a system to itself, so with that many systems it's very likely that the particles involved there have sppawned some kind of organism. Wether they are advanced enough with intergalactic space travel or not we cant tell. And as for the universe being infinite, with the way our minds work we cant fathom it being anything but infinite, i mean if it was a sphere, then there must be an end somewhere. And at that end, what is on the other side, white? or black? and if we got through it what would we see? would we be able to get through it at all? so many questions we cannot answer with our current knowledge. Our knowledge of the universe is only very small, cause we are only a very small part of it, anyone who claims to know how the universe works or to know everything about physics is a liar, we cannot know everything about our world untill we have seen everything about our world. (I don't mean planet.) But if the universe is infinite how will we ever kno weverything, it's impossible. Boggling your mind yet? i have more!
Loch ness monster = myth, however there could just as likely be some large aquatic animal living in the lake, though i doubt its some fire breathing dragon lizard from mars, just a lizard like many other sea creatures.
as for time travel, i agree with the theory we travel to a different universe, because just think, you go back in time tostop adolf hitler from killing some jeuwes, you stop him, so history is changed, but if you stop him from doing it, then it never happened, and you in turn would never have gone back to stop him. This creates a cycle which is best described in a dr carl kruzelnitsky book, where the time machien falls on your grandfather before he spawned your father, creating a cycle that re occurs every 1 millisecond of you crushing you grandfather. anyway i cant remember the book but it was a good read, had stuff about why cants land on their feet at certain heights but not below 1.5 meters or sumthing. Anyway changing the past cannot occur, as it would change the future and therefore create an alternate future where that past didnt exist. just watch back to the future the doc talks about it in number 2, where biff steals the time machine and makes that other reality.
