There are many theories on how the world will end for us, on how the Earth and us with it will be destroyed.
First Theory: As you all know of the Big Bang, which is believed to be the start of the universe. Some say that the universe may go back to that little sized pearl and we will be destroyed. Second Theory: If you did not learn this in school, the sun is a star. And all stars have life and death. Their death is when they explode becoming a nova/supernova. Which means the sun will have one as well. They say eventually, the sun will end life and explode, destroying the Earth. These are the two main theories that I know about. What do you think? Do you think the universe will go back into the pearl sized amount of gas? Or will the sun blow us up? You decide. If you know of another theory, feel free to mention it. My Opinion: The first theory in my opinion is highly unlikely. I don't believe the whole universe will shrink back. If anything, the universe will keep expanding forever. I do believe in the second theory, but that will probably not last for another couple million or even billion years. If not that, we'll be destroyed by a meteor or colide with another planet, both seem to be unlikely. So if we don't get destoyed by another planet (by collision) or by a meteor, the sun will blow up on us. |

Wow, haha. This is a really interesting topic! A very science-y one.. My favorite type :)
If we don't kill each other with nuclar weapons and stuff, I have my own ideas of now the Earth will will end.. One: Grey goo will take over the world and kill us all. (If you're too lazy to follow the link, it's a fictional self-replicating nanobot.) Yes, I am a nerd who loves science. And of course, nanotechnology, which I studied quite a bit in July. Two: Seeing as I probably know know more about astrophysics than most of you, my theory is WAY different. I am warning you guys, this is gonna be long. OK. So do any of you know that the Earth's magnetosphere is changing? Like flipping literally. The magnetosphere is this "shield" for the Earth that causes magnetic North and South. When the magnetosphere flips, the North Pole will be the South Pole and vice versa. (There is proof of this, by the way. In ancient Chinese Pottery and volcanic rock and the Mid-Atlantic Ridge and lots of stuff.) It usually flips every few thousand years or so (I think), and but it's been 70,000 (I think) years since it reversed. (I'm not sure about the dates, but I KNOW it's long over due. I learned it in Astrophysics class.) Anyways.. As it reverses, the magnetosphere weakens. And since the magnetosphere is what protects us from the sun (CMEs, solar wind/solar flares, ect.), we get more vulnerable to it. Now, sun damage causes skin cancer, and scientists estimate that as the magnetosphere weakens, millions of people per year will die from skin cancer and other related things. That could be what destroys the Earth, but I'm not finished. Now, scientists have this theory that Mars' magnetosphere (yes, it was like Earth in its earlier years. They have sent SEVERAL missions and pretty much proved it) just.. disappeared. Now how could that have happened? Ok, you guys know that the liquid core is what generates the magnetosphere and the magnetosphere is what causes the liquid core to circulate, right? (I don't want to get into that topic too deeply.) OK! So over time, the liquid core of Mars cooled to the point it was solid. So when the core is solid, it can't circulate at all, causing the magnetosphere to just disappear. And when the magnetosphere just disappears, the planet is pretty much doomed. It's MUCH more vulnerable to the sun. What will happen? All the WATER is evaporated, the atmosphere disappears, all life forms die, ect. That's why they call Mars the "Dead Planet." And that's my theory. Not as long as I expected, but it's pretty long. I really wanted to cover other things, but seeing as it's like 2AM and I'm really tired.... BTW, they say the magnetosphere will most likely reverse in 400 years, so we don't have anything to worry about. |
