Undergrad Could it be that the Big Bang had no cause?

Click For Summary
SUMMARY

The discussion centers on the philosophical implications of the Big Bang event, specifically questioning whether cause and effect apply outside the universe. Participants assert that current scientific understanding does not provide insights into the conditions preceding the Big Bang, leading to speculation that "nothing" may exist beyond the universe. The conversation emphasizes that inquiries into unobservable phenomena fall into the realm of metaphysics, which is not permitted in this forum.

PREREQUISITES
  • Understanding of the Big Bang theory
  • Familiarity with concepts of cause and effect
  • Basic knowledge of metaphysics and philosophy
  • Awareness of forum rules regarding discussion topics
NEXT STEPS
  • Research the implications of the Big Bang on cosmology
  • Explore the relationship between cause and effect in scientific theories
  • Study the boundaries between science and philosophy
  • Investigate current theories about the universe's origins
USEFUL FOR

Philosophers, cosmologists, and anyone interested in the foundational questions of the universe's existence and the limits of scientific inquiry.

TL;DR
Could it be that everything in the universe is described by cause and effect, but we have no reason to believe that cause and effect remains valid outside of the universe?
Everything that I’ve researched into this seems to suggest that we know absolutely nothing about the universe at the beginning of the Big Bang event. Could it be that just nothing is there? Could everything in the universe be described by cause and effect, yet cause and effect does not apply outside of the universe itself?

Thanks :)

We have no knowledge of “outside of the universe.” Therefore you are asking for baseless speculation.

And more rigorously inline with PF rules, the question of what may or may not have happened at an event we cannot observe is really more about metaphysics and philosophy, which are expressly forbidden topics for this very reason. Sorry, donglepuss.

In the light of these valid comments, this thread is closed.
 
I always thought it was odd that we know dark energy expands our universe, and that we know it has been increasing over time, yet no one ever expressed a "true" size of the universe (not "observable" universe, the ENTIRE universe) by just reversing the process of expansion based on our understanding of its rate through history, to the point where everything would've been in an extremely small region. The more I've looked into it recently, I've come to find that it is due to that "inflation"...
