The Pion
As an example of one of the several particles that must stay, the pion “has a range of 1 Fermi”. This is a compression factor of close to 4 compared to a graviton. It is NOT a graviton, even though it probably was one at an earlier point in time.
The pion is a “mediator of nuclear force.” *
