A straight forward path to a path integration of Einstein’s gravity

Path integration is a respected form of quantization that all theoretical quantum physicists should welcome. This elaboration begins with simple examples of three different versions of path integration. After an important clarification of how gravity can be properly quantized, an appropriate path integral, that also incorporates necessary constraint issues, becomes a proper path integral for gravity that can effectively be obtained. How to evaluate such path integrals is another aspect, but most likely best done by computational efforts including Monte Carlo-like procedures. •Path integration is a form of quantization that all quantum physicists should welcome.•This elaboration begins with examples of three different versions of path integration.•A clarification of how gravity is properly quantized, using a path integral.•How to evaluate such path integrals, but most likely best done by Monte Carlo procedures.
