Agree, it seem unlikely that at one point there was noting (silch, nada, niente, zero, null,... not one single entity of energy) and next, something. If this is true, something has always existed in one shape or form. So forever and ever. The "existence" is constantly changing shape and form.

The only thing we can be absolutley sure of is that evereyting is going to change.

Well summarised TNT, and in line with the quantum creation hypothesis that I outlined earlier.

If by 'nothing' we mean a vacuum, then we should realise that to particle physicists a vacuum is not empty space, but is a physical object, endowed with energy, density and pressure.

When a high energy vacuum decays into a low energy vacuum, the extra energy is released as a fireball of particles, antiparticles and radiation.

The 'inflation' process which formed our own little 'bubble' universe ended 13.7 billion years ago. However, in remote parts of the farther, unseen universe it is still continuing. Regions like ours are constantly being formed. This never-ending process is called eternal inflation.

Disco-Pete won't accept this - nor should he - it is just a HYPOTHESIS! 😉

Give me the facts.

btw, something just ocurred to me. When you say "farther, unseen parts of the universe", are you referring to farther toward the Big Bang, or farther away from the Big Bang? So my question is, how do we know what direction we're looking in? Do we know our trajectory and how fast we're moving? Or, are we "Lost In Space"?
 
Isn there a name for everything? I suppose once Universe really ment everything but then someone came up with "Observable Universe" (instead of the observable part of Universe) and Multiverse (instead of Subverse 🙂). Universe is everyhting - all we see and the bloody rest of it, being it in 7th dimension 🙂

And I agree - vacuum isn't "nothing"! Nothing is much more barren... 😉

Neither!

A big bang took place in the particular bubble universe that we occupy.

In the wider universe (in the sense of all that there is) other big bangs took place in other bubble universes.
How do you come to this conclusion? Is there any evidence whatsoever that points in this direction? I'm not averse to this notion as it simply confirms a whole single existence. But why a modular one?
 
Because even on these scales, logic rains. The other option is not allowed to discuss here. Which I think is good.

What makes you think the other option is not logical? Because it's banned here? Einstein built his theorums within this context, as did probably all his contemporaries and those before him. The problem is the "other option" is always confused with Einstein's context, hence my statement "no, it is actually cats and dogs". 😎
