Will every object in the universe evaporate?

In summary, the concept of whether every object in the universe will eventually evaporate relates to the principles of thermodynamics and quantum mechanics. As the universe expands and cools, it is hypothesized that even massive objects like black holes will lose energy through a process known as Hawking radiation. Over unimaginable timescales, this could lead to the gradual evaporation of all matter and energy in the universe, suggesting a future dominated by low-energy states and dispersed particles. Ultimately, while the exact fate remains uncertain, the idea posits a universe that could reach a state of near-total entropy.

TL;DR Summary
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.
