  • Physics happens right in front of us all the time. If you think it’s wrong, you need to show how in order to be believed; a lot of people have measured it and gotten the traditional results.

    however, i keep thinking that cosmic expansion will lift things out of a gravitational potential over time.

    Heat death is about statistics, not gravity. A “typical” physical situation is a situation you can’t run a machine or a living organism on, basically. The universe started in a “weird” (low entropy) situation, but seems to be wandering back towards a typical (high entropy) one as things happen.

    Black holes outlasting everything else is a different thing that might happen in the far future.

    or, in case cosmic expansion does not continue exponentially (but slows down over time), then the laws of physics would change over time;

    Not sure where you heard that. Cosmic expansion staying too small to really notice at normal scales, and physics running the same way as ever is a definite possibility.

    BTW, in the future, you’ll get more nice, helpful replies if you frame it as “why doesn’t X alternate possibility happen?”. That’s usually a great question and an opportunity to learn, and it doesn’t disrespect anyone.
