What Are the Four Fundamental Forces of Nature?

Click For Summary
SUMMARY

The discussion centers on the four fundamental forces of nature: gravity, electromagnetic force, weak force, and strong force. It establishes that Newton's law of gravity is superseded by Einstein's general relativity, represented by the equation R_{\mu \nu} - {1 \over 2}g_{\mu \nu}\,R + g_{\mu \nu} \Lambda = {8 \pi G \over c^4} T_{\mu \nu}. The electromagnetic force is described by Quantum Electrodynamics (QED), which quantizes the Coulomb force. The weak and strong forces are acknowledged as complex and convoluted, with no current grand unified theory bridging general relativity and quantum field theory.

PREREQUISITES
  • Understanding of Einstein's general relativity
  • Familiarity with Quantum Electrodynamics (QED)

I'm afraid it doesn't work that way. Physics is way, way more complicated then that.

-Newton's law of gravity is incorrect. What is currently accepted as the correct description of gravity is Einstein's general relativity which is extremely mathematically complicated but the basic field equation looks like: [itex]R_{\mu \nu} - {1 \over 2}g_{\mu \nu}\,R + g_{\mu \nu} \Lambda = {8 \pi G \over c^4} T_{\mu \nu}[/itex]

-The electro-magnetic forces are governed by QED which, for lack of a better desciption is quantum mechanics with a coulumb force which has been quantized.

-As for weak and strong I actually have no idea, it's never been relevant for me but I know they're both notoriously convoluted.

Plus, we don't have a grand unified theory. general relativity does not mesh with quantum field theory.
