The issue is that even in your framing “…’nothing’ at any point in time…” is at odds with the Big Bang theory which says time had a beginning. How do you conceive what was there ‘before’ the universe came to existence? (In the absence of matter, space, time and energy)
- kromem 2y agoThat's a common misconception. The big bang theory does not say that there wasn't stuff before the big bang. Simply that our local version of spacetime expanded in the great inflation. And I'm not sure if you've been following the news on it, but there's some serious issues with the theory at the moment.
- pixl97 2y agoIt doesn't matter which 'serious issues' exist, no one has any explanation for why the future points to a high entropy version while the past point to a low entropy version. You can have issue with any particular issue of the big bang theory, but no matter what you put forth you have to answer the very hard question of 'why was entropy low', being that we know of no way in our current universe to reset entropy.
- marcosdumay 2y agoYou mean stuff like this? https://en.wikipedia.org/wiki/Eternal_inflation https://en.wikipedia.org/wiki/Eternal_inflation People don't spend much time on those theories because they are inherently of little practical consequence. What includes that they are also not clearly testable.
- NayamAmarshe 2y agoEven physics has limits because our physical reality and approach has limits. Not everything can be a controlled experiment, especially things that are way beyond what our senses allow. So in the end, everybody's theory holds 'almost' the same weight. We're all clueless, yay!
