Is gravitation faster than light?

Click For Summary
SUMMARY

The discussion centers on the nature of gravitation and gravitational waves in relation to the speed of light (c) and black holes. Participants assert that gravitational waves propagate at the speed of light and that gravity itself does not escape from a black hole; rather, it is a result of the black hole's curvature of space. The conversation also touches on theoretical concepts such as tachyons and the behavior of gravitons, emphasizing that while mass cannot exceed c, gravitational interactions are complex and influenced by the geometry of spacetime.

PREREQUISITES
  • General Relativity (GR) principles, particularly regarding black holes and spacetime curvature.
  • Understanding of gravitational waves and their propagation characteristics.
  • Familiarity with the concept of tachyons and their theoretical implications.
  • Basic knowledge of quantum field theory, particularly the role of gravitons.
NEXT STEPS
  • Explore the implications of General Relativity on black hole physics and gravitational wave emission.
  • Research the Dirac theory and its relevance to faster-than-light particles.
  • Investigate the properties and theoretical existence of gravitons in quantum gravity.
  • Study the Schwarzschild radius and its significance in black hole dynamics.
USEFUL FOR

Physicists, astrophysicists, and students interested in gravitational theory, black hole research, and the interplay between gravity and quantum mechanics.

Some interesting relationships are arrived it by considering inflation to be an on going phenomena - the universe then is in a state of increasing negative pressure - energy is continually added in the form of spatial stress - the total energy is proportional to the surface area of the Hubble Sphere, the density is proportional to 1/R, there is no singularity at the beginning, the total energy (negative potential plus stress) is always zero ...
