I have a scenario which I am too poorly knowledgeable to address, I'm hoping for some expert input.
I'm currently writing a novel, in which a large section of Russia/EU continents were blown up in a fusion/nuclear explosion or perhaps meteor impact (it's less relevant to the post-apocalyptical plot besides radiation).
So now the Earth has been spun off access, with a large chunk blown off the side (think like a bitten apple). The earth was cast in a outward trajectory away from the Earth, with permanent sunshine on America for 213 years whilst still allowing vegetation/evolved human life. The Earth has now rotated away from the sun allowing it to set in the East for those in America.
The debris from the explosion/impact most notably formed 2 large moons. When there was still sunshine for the 213 years - The 1st caused a 3 1/2 hour eclipse, followed by a window of light for 40 mins, with the second causing a 5 hour eclipse. These near replicated the day/night cycle at least for human life, but I imagine would wreck havoc on the weather. Now the sun is too far East to be seen for however long, there will only be moonlight when the two moons are in orbit.
How scientifically, if remotely possible, could any of this theoretically happen. I should say that following the event I only need the Earth to be stable and supportive of life for around 250 years (the moons can join, crash into earth, etc after that hah).
I know I love a good theoretical challenge in my own field, so any inquisitive minds like mine I'd love any and all input, be it astronomy or meteorology. Thanks for taking the time to read, I posted after seeing a great response to a 3 hour eclipse.
