SUMMARY

The discussion clarifies that the acceleration of the universe is a metric expansion rather than a proper motion acceleration. This means that, unlike the sensation of acceleration experienced in an elevator, the universe's expansion does not produce a tangible feeling. Instead, objects in the universe simply move farther apart over time, which is a fundamental aspect of cosmological dynamics.

PREREQUISITES
  • Understanding of cosmological principles
  • Familiarity with metric expansion concepts
  • Basic knowledge of proper motion vs. metric motion
  • Awareness of general relativity implications
NEXT STEPS
  • Research the concept of metric expansion of space
  • Study the implications of general relativity on cosmic acceleration
  • Explore the differences between proper motion and metric motion
  • Investigate current theories on dark energy and its role in universe expansion
USEFUL FOR

Astronomers, physicists, and students of cosmology seeking to understand the nature of universal acceleration and its implications for the structure of the universe.

Why we don't feel the universe acceleration ?

Thanks in advance

The acceleration of the universe is a metric expansion, not a proper motion acceleration. Nothing "feels" the acceleration because it's not the same thing as going up in an elevator, which is actual acceleration. In the universal acceleration on cosmological scales, things just get farther apart.
