Black Holes Like Boiling Water ⚡ экспресс
Van der Waals black holes are solutions to Einstein's equations that, thermodynamically speaking, behave like real fluids. The authors checked whether the universal extremality rule holds up when you throw in quantum corrections from three theories (GUP, EUP, rainbow gravity). Turns out, the rule survives—just in a more generalized form. Topological analysis showed that black holes swap stability classes and winding numbers: in some cases, everything’s stable; in others, you get three independent charges or total neutrality. It’s like a genetic code that, when mutated, expresses different features but keeps its core intact.
Some black holes behave like water: they can boil and condense. Their entropy (disorder) was once measured by the horizon area — a discovery by Jacob Bekenstein and Stephen Hawking. But quantum effects made entropy more complex; yet the link between extreme states endures — like a water droplet that boils and evaporates but still obeys the general laws of liquids.
Scientists have built a topological map of states marked by charges. Different quantum corrections draw different maps. In one case, charges are stable; in another, they break into groups, but the total sum of their weights remains unchanged. These charges are like bubbles in a boiling droplet: their arrangement shifts, but the collective 'importance' stays the same. The most surprising part: the more massive a black hole, the colder it gets. The record-holders are colder than the cosmic background — their temperature is near absolute zero.
