What would happen if the sun dies?
Short answer, we will die. Long answer.....First the sun will expand into a red giant during the throes of death, then it will vaporize the Earth. The time scale is at least — 7 billion or 8 billion long from now, so you don't need to be scared that you will die, but when that happens the sun will "eat" the earth, but probably won't be there.
What will happen if the eart was flat?
We all know that the Earth is not flat. Well, almost all of us.
