... and 'parallel universes' refers to this universe of ours replicating with slight differences. all off these parallel worlds would make up the greater multiverse. therefore i am not saying that there is more than one 'everything' but i am saying that there would be infinite membranes of 'universes/worlds' inside this one 'everything'.

@leftaroundabout @itsminutemaid Thankyou for the discussion, it is interesting to read all sides to this argument. So much of what we know is still theories and caught up in opinions. I agree that the term universe has become hazy as we have discovered so much more outside of it original confines. I refer to 'the universe' as our part of the universe, the part that we know about right now, the part which holds the galaxies and stars that we have given names to...

Very good video! Mostly enjoyable.. And very nice landscape

@leftaroundabout Well, anyhow, did you read the rest of my comments? P.S. It's been good debating with you

[leftaroundabout]

@itsMinuteMaid You're absolutely right there, many people are against using the word universe in its old sense. I personally think it's better to keep the old meaning of that word and invent new words ("multiverse") for each subsequent level of understanding rather than having to shift the nomenclature every time something new is discovered, because that always leads to some confusion just like it did here. It was probably unwise to call it "universe" to start with, but that can't be undone now.

[itsMinuteMaid]

@leftaroundabout All that is besides the point. Say we deem the word "universe" to mean "all that is known or accessable by our current level of understanding and technology", or whatever. Then there becomes a need for a word to denote the "complete totality of all that exists". That is, all these "universes" combined, and whatever else that exists, what would you call that? Whatever it is, there can only be one. You can't have more than one of "everything". Unless speaking paradoxically.

[leftaroundabout]

@itsMinuteMaid That's not what I meant. "atom", as well as "universe", is a word whose original meaning isn't quite appliable any more now: atoms are not indivisible, and what we used to call the universe may not include everything that exists - that's why it is not wrong to speak of many universes, meaning "many things-we-used-to-believe-incl­uded-everything-there-is". The exact definition of the word universe now varies, not all authors use the same.

@leftaroundabout Now, with that theory that every time an action is done a new realm of existence is created, and if one is able to somehow travel to one of those realms that has been created ("travel back in time"), then would you be simultaneously creating a realm of existence, and entering one that already existed. A paradox. So, that's when your "both" comes in. That is, that one would be replicating and old "universe" and simultaneously accessing a new one. Now my head hurts. Thanks.

@leftaroundabout ...As far as what you said concerning time travel, you are still confusing a replicated version of ones existence for their initial existence. If in fact new realms, planes of existence or "universes" (as you state them), are created every time any action is done, then yes, one could travel throughout time by somehow accessing those alternate "places". It would be like being able to go into this girl's youtube video and in her "universe" I would be there, but as well here.
