TL;DR Summary
Could there be new particles after the universe will reach heat death?
Apparently, among the options for the fate of the universe, the universe reaching heat death in the extremely far future is the most likely one, after the last black holes would have evaporated (https://en.wikipedia.org/wiki/Heat_death_of_the_universe)

But, even if objects in extremely long timescales would quantum tunnel into black holes by quantum fluctuations, could there be also some quantum fluctuations that would make new particles to form (using the energy "leftovers" of the universe after heat death)? Or because energy (like electromagnetic radiation) will be redshifted, there will be a point where this would be impossible? Is there any "escape" or loop-hole to heat death?

As @PeterDonis said last time, "The answer to this is the same as the answer to all the other threads you have posted asking the same basic question."
 
There is no way of answering this question since we have no accepted theoretical model. Thread closed.
 

Thread 'Gravitational self-interaction: another attempt to replace Dark Matter'

https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...

Thread 'Twistors and celestial holography'

Many of us have heard of "twistors", arguably Roger Penrose's biggest contribution to theoretical physics. Twistor space is a space which maps nonlocally onto physical space-time; in particular, lightlike structures in space-time, like null lines and light cones, become much more "local" in twistor space. For various reasons, Penrose thought that twistor space was possibly a more fundamental arena for theoretical physics than space-time, and for many years he and a hardy band of mostly...
