We wouldn't say that Big Bang came from "nothing." Right after the Big Bang (which wasn't really an explosion, but rather the start of the expansion of the Universe), the Universe was in a very hot, dense state. In fact, it was entirely dominated by radiation (no matter!).
Now, you may have heard that matter can be converted into energy, but the reverse is also true. Energy can be converted into matter. In the early Universe (we're talking the very first second!), this is exactly what happened.
The radiation was converted into the first protons (hydrogen). A few minutes later, there was a short period where some of the hydrogen fused into helium and a teensy bit of lithium. The very first stars formed from this material.
The fusion that takes place in their own cores gave us all the heavier elements that we see today. Now, where the radiation that was converted into the hydrogen came from and what came "before" the Big Bang, these are questions astronomers don't know the answer to right now and may never know.
You are having the same mental block that many people have when trying to imagine the Big Bang, which is that you think that time exists outside the universe and goes on forever. Neither of those is true. Time only exists inside the universe, and it started at the Big Bang.
Because of that there was never a time when there was nothing. As far as we know the Big Bang came from an initial singularity. The singularity didn't come from anything because there was no before for anything to be in.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
