If all massive objects emit Hawking radiation, not just black holes alone, then everything is unstable, even the Universe. Can that be true?

Key Takeaways

• Back in 2023, a team of researchers put forth the bold suggestion that Hawking radiation, which causes black hole evaporation, might emerge from all massive objects, not just black holes.
• If this were true, then all massive objects would slowly lose energy (and, therefore, mass), and as a result everything would eventually decay. Ultimately, the Universe itself would even end.
• Rather than talk about what could be true if this scenario holds, we can look at the fundamental issues underlying the idea, not just an approximation. It turns out not to be physically possible.

Here in our Universe, a common refrain is that, “this, too, shall pass.” Our night sky is alight with a vast array of planets, stars, and galaxies: indicative of the complex structures that have formed through the relentless effects of gravitation over the past 13.8 billion years. Although quintillions of new stars will no doubt form...
