Galaxies are flying apart at faster than the speed of light so it is space that is expanding I believe. — Devans99
Ok.Galaxies are flying apart at faster than the speed of light
What directs to such a conclusion?so it is space that is expanding I believe.
infinity is unmeasurable so has no size so cannot expand. — Devans99
The expansion of the universe — Devans99
So it is the metric that is expanding. — Devans99
So you doubt the Big Bang theory? — Devans99
The red shifts of galaxies seem to clearly show expansion starting 13 billion years ago. — Devans99
The Cosmic Microwave Background radiation confirms the Big Bang also? — Devans99
Just a big bang. They have discovered a lot of those and there's no guarantee that the one they reference as 'the big bang' is the first and only one of its kind. It is possible that with the hypothetical of a multiverse, there is potential for multiple big bangs for each universe. — BrianW
That sort of leads to a pet theory of mine: if big bangs were naturally occurring and time was infinite then there would be (with infinite time) infinite big bangs at each point in space leading to infinite matter density. So either the Big Bang was an unnatural singleton or time has a start. — Devans99
Therefore it follows that all universes are connected to all universes. In what sense is that a multiverse if they are all connected? — Devans99
Not necessarily. Even if there was infinite matter density, each part of the universe would only interact in relation to its environment. It does not mean that the potential for the whole universe would act in its absoluteness at every point. Also, there already have been multiple super and mega novas in this supposed universe since that hypothetical big-bang and matter still seems to be relatively well-organised. — BrianW
So, for me, if there's one universe, there's bound to be others. And why not? — BrianW
For example, after the super and mega novas (and even the big bang) there follows a considerable period of 'calming' sorta like regaining equilibrium. Therefore, it may be that even with infinite time and a continued occurrence of big bangs, the equilibrium may still be maintained — BrianW
Like I said, time is finite. — Devans99
We have evidence of only one Big Bang — Devans99
