Will every object in the universe evaporate?

Click For Summary
SUMMARY

The discussion centers on a recent paper asserting that every massive object in the universe will eventually evaporate through Hawking radiation, similar to black holes. Critics have raised concerns about the paper's validity, but the authors remain unconvinced by these critiques. Despite the intriguing premise, the conversation highlights the speculative nature of the topic, emphasizing the lack of a comprehensive theory of quantum gravity and the absence of evidence regarding quantum aspects of gravity.

PREREQUISITES
  • Understanding of Hawking radiation
  • Familiarity with black hole physics
  • Basic knowledge of quantum gravity concepts
  • Ability to interpret scientific papers and critiques
NEXT STEPS
  • Research the implications of Hawking radiation on black hole thermodynamics
  • Explore current theories in quantum gravity, including string theory
  • Investigate the critiques of the paper mentioned in the discussion
  • Study the relationship between mass, evaporation, and particle physics
USEFUL FOR

Astronomers, physicists, and anyone interested in theoretical physics, particularly those exploring the future of massive objects and the nature of black holes.

TL;DR
Will every object in the universe evaporate?
According to a recent paper (https://arxiv.org/abs/2305.18521) (explained here: https://www.ru.nl/en/research/resea...verything-will-evaporate-not-only-black-holes) every massive object in the universe will evaporate in a similar way into Black Holes through Hawking radiation.

I've seen some critical comments (https://arxiv.org/abs/2306.07628) to the paper indicating that it's wrong in many aspects, but the authors do not seem convinced (https://inspirehep.net/literature/2690645) of these critics

Therefore, even if the authors are correct and the paper is right, would all objects in the universe evaporate? Would there be any way to avoid it? Would even individual massive particles "evaporate"?

The answer to this is the same as the answer to all the other threads you have posted asking the same basic question. All of this is speculation; we have no theory of quantum gravity and we have no expectation of getting any evidence about quantum aspects of gravity any time soon. So the question you are asking is unanswerable.

Thread closed.
