SUMMARY

The discussion centers on the concept of aging in relation to the universe's expansion. Participants argue that if the universe were not expanding, time could potentially run faster, leading to accelerated aging. However, they emphasize that without a reference point, such as another person's aging process, individuals would not perceive any difference in their own aging. The conversation concludes that the question of aging faster or slower is inherently flawed due to the lack of comparative measures.

PREREQUISITES
  • Understanding of relativistic time dilation
  • Basic knowledge of cosmology and the Big Crunch theory
  • Familiarity with the concept of reference frames in physics
  • Awareness of the implications of universal expansion on time perception
NEXT STEPS
  • Research the effects of relativistic speeds on time perception
  • Explore the Big Crunch theory and its implications for time and aging
  • Learn about reference frames in Einstein's theory of relativity
  • Investigate the relationship between cosmic expansion and time dilation
USEFUL FOR

This discussion is beneficial for physicists, cosmologists, and anyone interested in the philosophical implications of time and aging in relation to the universe's expansion.

Would we be getting older faster if the universe wouldn't be expanding?

Compared to what? If time were "running" faster throughout the universe, we wouldn't notice because there would be nothing to compare it with.

Notice that if one person were traveling much faster than the other he would see the second "aging slower" but would not think of himself as aging any faster than normal (and, in fact, the second person would see the first person as aging slower!).
 
The question was incomplete.
We wouldn't feel any difference in any case, but time would run faster. That's the thing I don't know...what could we compare with our time?

Yes, possibly, depending on what you consider the alternative to expanding. If you are considering contraction, as in back toward the Big Crunch, then time would move faster, and so would aging.

Well, what would be your reference to 'aging slower' or 'faster'? If time was running any slower or faster due to the rate of expansion in the universe, no one would notice, since there would be no reference to compare what would be faster or slower. Least that's how I see it.
