APPENDIX B. General Relativity

APPENDIX B:

SUMMARY

In QFT, the gravitational field is a force field like the EM, strong, and weak force fields, but with a higher spin of 2. Space is the same three-dimensional “Euclidean” space that we intuitively believe in, and time is the same time that we intuitively believe in. Four-dimensional curvature is best left to the physicists who find it useful in their calculations.
