What is the string worksheet? How does the string worksheet explain quantum gravity?

I think you're referring to String Theory, which essentially says all matter, at its most quantum level, is made of tiny string-like objects. In String Theory, as far as I understand, gravity is a very weak force that has little effect on the quantum actions of these "strings. " From any perspective through which gravity is viewed, we cannot affirm its speed.

Being that it is such a weak force, it has not yet been observed in a laboratory.

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.
