Here's a good clip from Anton Petrov about the current Big Bang situation and why the Media fuss that James Webb Telescope discoveries. https://www.bing.com/videos/search?q=anton+petrov&&view=detail&mid=4F94947F9CA5E...

Here's something of related interest
The 'Voids' as possible Dark Energy.
The Theory that the massive voids that are withing the Cosmic Web of Galaxies (Filaments and Clusters) are expanding to the point where in another amount of billions of years - most galaxies will be isolated and sparse.
Interesting in my view, in that 'where does the universe go from there' if it becomes a cold dark vaccuum of stretched sparcity of heat?

Think of a vacuum as consisting of matter and antimatter pairs constantly being created and annihilated, with particles and antiparticles colliding, creating energy in the process. Couple that with the fact that dark matter (also dark energy) appears to be associated with the vacuum in space. (The voids) From the cosmic background radiation, the average temperature is 2.7 Kelvins. That may not sound like much in terms of energy, but spread it over enormous regions of space and it becomes significant.

I think the solution lies somewhere in that area of research. At least some dark energy is vacuum energy.

Also consider that the gravitational interaction of antimatter with matter or antimatter has not been observed by physicists. While the current view among physicists is that gravity is expected to attract both matter and antimatter at the same rate that matter attracts matter, this is not yet experimentally confirmed.

The density of a vacuum is close to zero, while on the other hand, the gravitational interaction of a vacuum is likely to be quite significant.

No concrete answers as yet, but a lot of clues.

If we did that, should we not wonder about where the energy of such a reaction is?

I added to my post as you were replying. The average temperature of space is 2.7K. (2.7 above absolute zero.)
