Quantum Field Theory without Divergences: Quantum Spacetime

G. H. Gadiyar

Abstract

A fundamental length is introduced into physics in a way which respects the principles of relativity and quantum field theory. This improves the properties of quantum field theory: divergences are removed. How to quantize gravity is also indicated. When the fundamental length tends to zero the present version of quantum field theory is recovered.
