Does E in E=mc^2 Include Gravity?

Click For Summary
SUMMARY

The discussion centers on whether the "E" in Einstein's equation E=mc² encompasses gravitons, hypothetical massless particles that mediate gravitational forces. Participants assert that if gravitons exist, they would not contribute to mass (M=0) but would possess momentum, thus fitting into the extended equation E² = M²c⁴ + P²c². This indicates that while gravitons do not add to the mass-energy equivalence directly, their momentum still contributes to the energy described by the equation.

PREREQUISITES
  • Understanding of Einstein's mass-energy equivalence (E=mc²)
  • Familiarity with the concept of gravitons in quantum physics
  • Knowledge of relativistic energy-momentum relations (E² = M²c⁴ + P²c²)
  • Basic principles of momentum in physics
NEXT STEPS
  • Research the implications of massless particles in quantum field theory
  • Explore the role of gravitons in theories of quantum gravity
  • Study the differences between classical and relativistic momentum
  • Investigate experimental evidence for the existence of gravitons
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the intersection of quantum mechanics and general relativity.

Does the E in E=MC^2 include the gravitons?
 
Physics news on Phys.org
Assuming gravitons exist, they would be massless and would fall under the equation E2 = M2C4 + P2C2, where the M2C4 portion is zero (because m is zero) but the P2C2 portion is non-zero, as gravitons would have momentum.
