Apparently not!

Not in the way they are saying it happened. Space is something like a substance that is part of universe. It was created at the moment of the big band and is expanding, but nothing exists beyond it.
Another point of interest, everything we see in the universe makes up ~5% of what is there. ~24% is dark matter which exerts gravitation force or galaxies would fly apart, but we have no idea what it is made of. Rest of universe is dark energy which is causing expansion, but again no idea what it is. So universe came from nowhere and we only know what 5% of it is, and no idea why the forces of nature, gravity, strong nuclear force are what they are?

I can believe that.

E=mc(squared) implies that matter can be created from energy. It's not a one way street.

I'd heard it was "Honey, hold my beer while I light this."

So much we don't know... There is not even consensus on how a signal propagates along a conductor. Schools still teach that electrons flow like water in a pipe.... Even B. Franklin had it wrong about current direction; hence conventional current and electron current. You think the Canonite Nikonite battles are bad here, go on an audio site and start discussing high end cables and signal propagation... Ha Ha
Ben Franklin did not know the direction current flowed because he had no instrument to tell him and he had to guess. He did guess wrong. I was taught that AC current flows through the wire like water in a pipe and DC current travels through wire only on the surface of the wire. That is why household wire (Romex) is single stranded and automotive wire is multi stranded. The information may have changed and I would be open to knowing.

I hear you... Yes, to the best of our knowledge current does flow, but NOT electrons as books still teach... They might wobble and move a little but the charges are the things that flow... I belong to a lot of audio forums and do not profess to be any authority on electronics but it seems there is STILL no consensus on how a signal propagates along an audio cable... Through the center, on the exterior, or maybe along the magnetic field... Therefore we have our own constant flame wars between the different custom cable manufactures as WHY their designs transmit with less distortion Etc... BTW, very interesting info on DC and AC and how they travel... A little exchange of info is nice without folks resorting to insults etc... BTW, I DID buy into Upper end cable and I DID notice a difference... subtle, but noticeable. Maybe just the " Expectation effect " but then again who cares as long as it is REAL to you...

I believe our universe is just like an atom in an even larger universe
