SUMMARY

The discussion centers on the gravitational paradox arising from the observation that galaxies outside the observable universe are receding from Earth faster than the speed of light. This phenomenon challenges Newton's law of universal gravitation, as the gravitational force should weaken with increasing distance. The paradox suggests that if gravitational force does not weaken, it contradicts established physics. A proposed solution is that changes in gravitational force occur instantaneously rather than at the speed of light, which would conflict with Einstein's general theory of relativity.

PREREQUISITES
  • Understanding of Newton's law of universal gravitation
  • Familiarity with Einstein's general theory of relativity
  • Basic knowledge of cosmology and the observable universe
  • Concept of the speed of light as a universal constant
NEXT STEPS
  • Research the implications of instantaneous gravitational changes on physics
  • Explore alternative theories to Newton's law at cosmological scales
  • Study the effects of dark energy on galaxy movement
  • Investigate the relationship between gravity and the fabric of spacetime
USEFUL FOR

Astronomers, physicists, and cosmologists interested in the fundamental laws of gravity and their implications at large scales will benefit from this discussion.

Galaxies outside the observable universe are moving away from the Earth faster than the speed of light. As the two bodies move apart, the gravitational force between them should weaken however as the speed of gravity is equal to the speed of light, the gravitational force would not do so. It is now that a paradox arises, for if the gravitational force between the two bodies is unable to weaken, then Newton's law of universal gravitation is compromised. The issue can be solved if the change in the force of gravity between two bodies occurs not at the speed of light but is instead instantaneous. This, however, would compromise Einstein's general theory of relativity. How can this paradox be solved or simply dismissed?

Newton's law of Gravitation is compromised. It simply doesn't work at cosmological scales.
