SUMMARY

The discussion centers on the concept of universe expansion occurring at speeds exceeding the speed of light. Participants clarify that this phenomenon is not about objects moving through space but rather the expansion of space itself. The rate of expansion is measured in units of 1/time, indicating that there is no upper limit to how quickly distances between objects can increase. This understanding challenges the traditional notion of light speed as a universal speed limit.

PREREQUISITES
  • Understanding of general relativity and its implications on space and time
  • Familiarity with the concept of cosmic expansion and Hubble's Law
  • Knowledge of the speed of light as a universal constant
  • Basic grasp of the metric expansion of space
NEXT STEPS
  • Research the implications of general relativity on cosmic expansion
  • Study Hubble's Law and its significance in cosmology
  • Explore the concept of metric expansion and its mathematical representation
  • Investigate the observable universe and the effects of dark energy on expansion rates
USEFUL FOR

Astronomers, physicists, and anyone interested in cosmology and the fundamental principles governing the universe's expansion.

I had seen somewhere that Universe is expanding with a speed greater than Light Speed... it really sounds absurd for me... As per my sense, light speed is the universal acceptable speed limit and we can't get back if we reach that speed until any other thing outside the object makes it to decelerate..

I mean every thing within the Object gets freezed in Time and So how is it possible for an expansion with such speed..?

Expansion is not associated with a speed because it is an effect of space itself growing, not with things moving in space. Expansion therefore is given by a rate, measured in units of 1/time.

Since it is an effect of space growing and not of anything actually moving, the speed with which the distance between two objects grow can be greater than the speed of light. There is no such upper limit on the rate of spatial expansion.
