Is it certain that our universe, or better, the particles it consists of, will fall apart one day in the far future?

So that the Universe may never end?
By that theory universes may end, but there's always a new supply since each one begats innumerable others.

What would happen to biological beings which could exist forever, would their matter decay ( after they finaly wont be able to get new matter)?
Is there a way that matter could exist forever and not fall apart?

In effect, a black hole from our universe would have to 'connect' with a black hole from another universe, allowing the exchange of matter.
On more infinite scales, a portal to the 4th spatial dimension would essentially be a white hole since 4D structures have infinite 3 dimensional structures/matter in them.

Matter trapped in a black hole eventually 'evaporates' back into the universe but no white holes as such.
...vacuum fluctuations cause a particle-antiparticle pair to appear close to the event horizon of a black hole. One of the pair falls into the black hole whilst the other escapes. In order to preserve total energy, the particle that fell into the black hole must have had a negative energy (with respect to an observer far away from the black hole). By this process, the black hole loses mass, and, to an outside observer, it would appear that the black hole has just emitted a particle. In another model, the process is a quantum tunneling effect, whereby particle-antiparticle pairs will form from the vacuum, and one will tunnel outside the event horizon.

Haha. Well, no, not according to scientists. That would imply the universe isn't a closed system and that makes scientists faint.
Scientists think every outside interference to be, well - religious - for a lack of a better word.

Unlike black holes, white holes cannot be continuously observed rather their effect can only be detected around the event itself. Gamma ray bursts are the most energetic explosions in the universe. Long gamma-ray bursts were connected with supernova eruptions. There is a new group of gamma-ray bursts, which are relatively close to Earth, but surprisingly lack any supernova emission. We propose identifying these bursts with white holes. White holes seem like the best explanation of gamma-ray bursts that appear in voids. We also predict the detection of rare gigantic gamma-ray bursts with energies much higher than typically observed.

With dark energy expanding the universe, parts of the universe will become unreachable and undetectable, as the pass beyond the point where their liht will be observable in a finite amount of time. As entropy increases
I'm quite skeptical about Heat Death.
The Big Bounce theory is much more harmonious with the workings of nature as we know it. That's how I see it anyway.

Why is there anything, instead of nothing? is a question philosophers have asked since ancient times. Nobody seems to know. But of course he would.

dark energy...a sort of cosmic antigravity — is speeding up the expansion of the universe.
If this continues, the future is really dark. Eventually the universe will be expanding so fast that most other galaxies will disappear from view forever. Eventually even atoms could be ripped apart.
...
Sometimes the universe seems to me like one of those black-humored toys: a box with a button. When you push the button, a hand comes out 14 billion years later and turns the button off.

Hope mankind can be saved, is there a chance to do something?
I doubt humanity will be around for 5 billion years more.
Regardless of the state of the universe.
I'm sure whatever evolves out of us, if we don't expire as a species, will have the mental capacity to deal with this one way or another.
Or not, sometimes things truly are hopeless, but considering the universe did start out somehow, seemingly from nothing , I wouldn't lose all hope. According to physics all rules we have right now won't apply after this universe ends, and who knows what freaky stuff will happen then.

It's like a movie where the entire audience dies before the really great ending.

Matter eventually maybe can be formed from energy ....
Matter and energy are the same thing
