Confusing Osmosis

AI Thread Summary

When hot milk is placed in a cool solution, it can taste like water at the bottom due to the separation of milkfat from the liquid. This phenomenon is not related to osmosis, as a closed jar is impermeable. The heating process may cause the milkfat to be forced out of suspension, altering the flavor profile. The discussion highlights a lack of personal experience with this occurrence, leading to speculation about the underlying science. Understanding the behavior of milk components when heated could clarify this taste change.

I've never experienced this phenomena, but a glass jar is not permeable, so it wouldn't be osmosis. It could simply be that heating the milk forces the milkfat out of solution/suspension.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev
