SUMMARY

The discussion centers on the concept of the universe's age, proposing a thought experiment that contrasts the perceived 19 to 20 billion-year age of our universe with a potentially much older "real" universe. The idea suggests that if the age of our universe is merely a fraction of the true age of the full universe, it could fundamentally alter our understanding of cosmic origins. Participants express skepticism about the speculative nature of this idea, questioning whether time is indeed "brane" dependent.

PREREQUISITES
  • Understanding of cosmology and the concept of the universe's age
  • Familiarity with brane theory in string theory
  • Basic knowledge of speculative thought experiments
  • Awareness of the implications of time in physics
NEXT STEPS
  • Research the implications of brane theory on cosmology
  • Explore the concept of the multiverse and its relation to the universe's age
  • Study the current scientific consensus on the age of the universe
  • Investigate the philosophical implications of time in theoretical physics
USEFUL FOR

Cosmologists, theoretical physicists, philosophers of science, and anyone interested in the fundamental questions of the universe's origins and the nature of time.

As a thought experiment, imagine this.

Suppose the age of the brane in which we exist is say the age we think that the "traditional" universe has existed.

Then suppose that the age of the "full", "real" universe (in which the brane resides) is such that its ratio to the age above is the same as the ratio of the age above to a nano-second.

Could this change your thinking about the origin of the "universe"?

The secret to where we came from is to realize that the 19 or 20 billion year age of "our" universe is like nothing.

Ah, the old greengrocer's apostrophe.

I don't think this is a thought experiment yet. It's just speculation.
 
So time is 'brane' dependent? I think that dodges the issue.
