Universes live and die just like human lives live and die, as with all in creation. Universes start in a big bang, can't tell you how they end, but I believe they just fizzle out.
Universes are as numerous as living things we witness. We reside within a universe, aka: the boundaries of our understanding.
In either event, I also do not think that the Big Bang was an event in the past. I think that we are still in it, whatever that event really is.
The idea that the universe is in a state of eternal statistical equilibrium has been shown false.
All the physical evidence we have points to an origin some 13.8bn years ago, and physical predictions based on this model are constantly being verified.
The universe is not eternal.
You mean unchanging?
There is a charming story, not taken seriously by all historians, about how steady state theory began. The idea came in 1947, Hoyle claimed, when he and his fellow scientists Hermann Bondi and Tommy Gold went to a movie... The movie was a ghost story that ended the same way it started. This got the three scientists thinking about a universe that was unchanging yet dynamic. According to Hoyle, "One tends to think of unchanging situations as being necessarily static. What the ghost-story film did sharply for all three of us was to remove this wrong notion. One can have unchanging situations that are dynamic, as for instance a smoothly flowing river." But how could the universe always look the same if it was always expanding? It did not take them long to see a possible answer — matter was continuously being created. Thus new stars and galaxies could form to fill the space left behind as the old ones moved apart. Big Bang or Steady State?
That would be to say around 13.8 billion years ago is when matter in our universe came into existence? What of the non-physical, such as energy, particularly in the form of photons?
it certainly would boggle the mind if it were, yet it seems that, at least in some way, it is. At the very least existence is eternal.
Also, perhaps our particular universe is not eternal - but that doesn't mean there was nothing before the first planck moment of the Big Bang. Could the birth of our universe be simultaneous with the death of another?
