SUMMARY

This discussion centers on the philosophical and mathematical implications of existence probabilities in an infinite universe. Participants argue that while the odds of any specific individual existing are astronomically low, the concept of infinite time and a potential multiverse suggests that existence could recur. The analogy of a lottery is used to illustrate that while the odds are slim, the occurrence of existence is not impossible. The conversation also touches on the distinction between philosophical musings and the physical principles governing existence probabilities.

PREREQUISITES
  • Understanding of basic probability theory
  • Familiarity with concepts of the Big Bang and cosmology
  • Knowledge of multiverse theory
  • Awareness of philosophical implications of existence
NEXT STEPS
  • Explore the implications of infinite time on probability theory
  • Research the Big Bang theory and its impact on existence
  • Study multiverse theory and its interpretations in modern physics
  • Examine philosophical perspectives on existence, particularly Nietzsche's views
USEFUL FOR

This discussion is beneficial for philosophers, physicists, and anyone interested in the intersection of probability, cosmology, and existential questions.

Hello,
Trying to make sense of the odds that I (or you) exist, from what I read people say its basically 0, which doesn't make sense to me since I am here after a short ~14 billion years of our universe existing.
Given IF the universe and time are infinite, my odds of existing again, no matter how small, over infinite time, as some conscious thing, should become very high?

thanks for help

I guess you mean apriori? Sure, the specific chain of events following from the Big Bang which led to your existence is only one possible history of many, and at the beginning of time it would have been safe to bet that you would not exist now.

But it is like the lottery; someone has to win (some (itself improbable) history or another has to occur). And thanks to selection bias you aren't going to observe any universe in which this magical chain of events did not occur.

And sure, if there is a multiverse then a being identical to yourself may one day spawn into being once more, given infinite time.

Nietzsche thought so, but that's philosophy. The odds of physical event are a question of Physics. If you want to assume an imaginary series of independent trials with a constant of probability of success, we could discuss a mathematical problem.
