If light transmitting without media, then

SUMMARY

The discussion centers on the nature of light transmission in the universe, asserting that light does not require a medium to propagate, which is a fundamental principle of physics. Participants emphasize that the expansion of the universe does not affect the speed of light, which remains constant at approximately 299,792 kilometers per second. The conversation concludes with a definitive statement that light's behavior is independent of the universe's expansion, reinforcing established scientific understanding.

PREREQUISITES
  • Understanding of the principles of light propagation
  • Familiarity with the concept of the universe's expansion
  • Basic knowledge of physics, particularly electromagnetic theory
  • Awareness of the speed of light as a constant
NEXT STEPS
  • Research the implications of light speed in cosmology
  • Explore the principles of electromagnetic radiation
  • Study the effects of the universe's expansion on cosmic phenomena
  • Investigate the historical context of light's transmission theories
USEFUL FOR

Physicists, astronomy enthusiasts, students of cosmology, and anyone interested in the fundamental properties of light and the universe.

then where light transmits to in the universe? Does that mean the universe expanding speed is at least light-speed? Because we know light is energy, it is part of our universe. As if it is like this, the universe expands endless and will become cold and dark.

It sounds impossible to me

Turn on a lamp. Notice the room gets brighter. That has nothing to do with the expansion of the universe. Light does not require a medium---that's just a fact of physics.
