The Planet Earth will eventually end

The difference between previous doomsday "predictions" and what I'm saying is huge, though. I'm not giving an exact date. I'm saying within a certain time period because after 10^10^120 years, we have sufficient understanding that the Universe will have collapsed in on itself, or will have dissipated, by measuring how the galaxies have spread apart, and even by measuring the different changes in rotation and orbit within our own solar systems, even with Earth and our moon. We have sufficient reason backed with strong examples that support an idea of the Universe either entering a "Big Bang" state, or being completely destroyed altogether. What I'm saying is basically an approximate end date of how far our Universe can expand or contract or survive, which will in turn destroy Earth, if it hasn't been destroyed in another way (which is incredibly likely) already. I'm not saying "in the year 57,098,999,741, a lone planetoid 6019Km in diameter will strike Earth in what is currently considered Italy, shattering the planet in half. I'm saying judging by how the Universe is currently changing, expanding, and twisting, it is reasonable to hypothesize that the Universe will come to an end in the distant future. The majority of doomsday predictions have been done by Religious people. Priests, Pastors, Ministers, Preachers, or simply religious followers make up most "theories." The most recent and commonly referred to one is the 2012 December 21st "prediction" by the Mayans. However, science and scientists do not back this theory up at all. Taken directly from Wikipedia - "The so-called Mayan apocalypse at the end of the 13th b'ak'tun. The Earth would be destroyed by an asteroid, Nibiru, or some other interplanetary object; an alien invasion; or a supernova. Mayanist scholars stated that no extant classic Maya accounts forecast impending doom, and that the idea that the Long Count calendar ends in 2012 misrepresented Maya history and culture.[88][89][90] Scientists from NASA, along with expert archaeologists, also stated that none of those events were possible." There is a huge list of predictions(1), you can see for yourself most are Religion-based, and the rest are not backed up by scientists at all. Regarding global warming, aliens, and science and religion mutuality, this is off-topic. If you are against the idea of global warming and aliens, I would be more than happy to debate you on that, as I believe both exist. Regarding religion and science mutuality - I'm not sure what you're saying. I don't believe religion and science should be taught or explained as fact mutually, as there is nothing at all that says any religion is anywhere close to 100% accurate or reasonable. The "practicality" of a doomsday is very high. You look at past "predictions," most are ridiculous religious claims, and the ones that are not, are ridiculous claims in general. Y2K? It's people thinking that when the 999 passes back into the 000's that all the computers will reset the time to 000 and we will be back in the stone age. Realize how ridiculous that is. Not many people believed predictions like that. Scientific predictions are absolutely nothing like that; they are predictions made for the distant, DISTANT future. Trillions of years+. Based on purely scientific research and findings. Previous doomsday "predictions" were strictly superstitions. "Stars exploding does not mean that the sun is going to explode" It does not guarantee that the sun will explode. However, witnessing other stars (our sun is a star) exploding after time, leads to a very high possibility that ours will some day, too. Also, we have observable evidence that our sun has in fact grown(2). The sun was not the only factor in the spawn of life. It's 20oC (70oF) in the "Summer" on Mars, yet we haven't found life there. We need many more factors to create life. Once again, I'd like it if you could give me a source for your claims about the Universe choosing to do something. Because the way most people (especially scientists, astronomers and cosmologists) see it, is the meteor that killed the dinosaurs was a random event. It was a rock floating through space, and happened to cross Earth's path at the right the time. Because it is changing does not mean the Universe can think for itself. We aren't really on the topic that the Earth will end one day - we've switched to how humans interpret what "universe" means, something I don't believe is relevant in this debate, as this debate has to do with the physical Universe and our Earth as a part of it, not how we act according to it, or because of it, or how it shapes our actions. This is completely irrelevant, but were you the one I had a discussion with about how to tell if someone is 100% ignorant? By saying we would have found life by now implies we have looked in so many places that it is reasonable to say there isn't other life forms in the Universe. I think you're missing how big the universe is and how little we've explored of it. In 1977 we launched Voyager 1(3) and last year (2013) it left our Solar System. That is currently the farthest we have sent something into space, with the ability to track and take pictures of everything. To put into perspective of how much we have explored, Voyager 1 is approximately 19,200,000,000km(4) from Earth. The distance from Earth to, let's say the closest Galaxy, Andromeda, is approximately 24,000,000,000,000,000,000km(5) from Earth. You know what that means? We've explored .00000008% of the distance from here to Andromeda. If you consider a complete straight, direct line from Earth to Andromeda to be how far away it is. We aren't accounting for anything other than directly toward the Galaxy; no planets or anything anywhere other than what's in our direct line toward Andromeda. And we've gone .00000008% of the distance, and you say if there was life out there, we would have found it by now? I wouldn't even be able to fit enough zeros into this reply if I told you the percentage of the entire Universe we've explored thus far. I'm not saying scientists know for a fact that something will or won't happen to Earth. But judging by the way the Universe is expanding, the way the galaxies are moving, the background radiation, the way stars and planets act when passing through black holes, the way "dark-matter" acts, etc, they can come to possible conclusions, but no 100% absolute certain conclusion. And by examining the evidence we have of past mass extinctions, it is highly possible that it can happen again. And if a meteorite can hit Earth, who's saying another planet can't? Saying a "true" scientist does not know is ridiculous. Of course they don't know for a FACT, but that's the reason they exist - to examine everything around them and the Universe and draw up ideas or scenarios or hypotheses on what CAN happen, what is very likely to happen, or what is not likely to happen. To say "I don't know, so I don't look into it" does not happen with scientists. Great ideas you've got, but you're toying with the semantics. I can say "what the dog feels is what I feel because his actions make me think he feels this way but in reality I am feeling this way and projecting my feelings by making it seem to me as though the dog is feeling that way." I am not talking about how we act or feel or view the universe; I am talking about space - not how we act based on it or anything. The planets. Nothing to do with a conscience - humans are not involved in this debate. I can say "you don't have as much knowledge as I do, therefore I'm right, and you're wrong" too. But you haven't shown anything that says what these scientists are doing is foolish. To study a phenomenon (say a star growing and expanding before letting out gamma bursts and dying) then use that experience and evidence combined with the fact that the sun is growing, to come to the conclusion that our sun (star) very well might act like all the other suns (stars) is reasonable, and not foolish at all.
