Welcome to Multiverse!

[tecboy]

Ever since I saw Cosmo on Fox network, it got me thinking about multiverse. I wonder is there another universe and what it is like. That sounds like science fiction but scientists are pondering about it. What if there is another universe and another version of me living in it and shooting Nikon dslr? Very interesting to think about.

seems implausible.

 

[tecboy]

You will never know. It can be true.

Haven't you figured it out yet......this is the Matrix.

your other self is watching you right now. This entire universe we live in is on their version of a microscope slide, miniscule, and your other self is peering in and watching you.

The basic premise of the multiverse is that the creation/expansion of space we call the "big bang" may in fact be a routine, ongoing process spawning many universes, each with its own set of physics, fundamental values, etc. As conceived, there is no communication between the various universes that may exist concurrently, since each occupies a different part of the space/time continuum, and in fact "space" and "time" as we perceive it may be part of the universe-specific set of properties. Even within our own universe, the outer boundaries of such a place are grossly outside out ability to "see" as that is limited by the finite speed for light, and the finite length of time the furthest photons may have been travelling. At this point, the "furthest" photons we can detect are the ones that came at the point of decoupling of energy and matter, when "space" became transparent to photons (roughly 13.7 billions years ago according to the latest thinking). With the relatively recent discovery that all space appears to be expanding, and that the cumulative expansion exceeds the speed of light (the speed "limit" is a property of the photon travelling "through" space, but is not a limit on the change of space itself), which means that more and more things at the "edge" of space as we perceive them, will soon be carried outside our ability to detect them using photons (since the photons travel more slowly than the cumulative space expansion).

A somewhat un-related set of speculations regarding the nature of space also postulates that the uncertainty principle implies that at each "bifurcation" or "choice" between two possible outcomes, both outcomes become real in their own versions of existence. In this viewpoint, there are uncountable number of universes splitting off from each other, each split carrying a decision of some kind. In this view, there is a universe in which we exist, and we chose "B" instead of "A", with the outcome that this implies. Of course, every decision by every person, thing, or even particle, creates its own universe, which kinda boggles the mind (my mind at least). On the other hand, there is no way of "disproving" this continual creation of whole universes with each decision, so we can't rule it out as being nonsense either.

It's really neat to be able to look at my gold wedding band and know that the element that I wear was created in the catastrophic merger of two neutron stars at least 5-6 billion years ago. We all are star-dust.

If you are speaking of a doppelganger universe does that mean that there are some posters on here that in their doppelganger form would post short, concise, responses to threads??? Not talking about you pgriz. :mrgreen:

Someone has been watching too much science channel. I know, I watch it all the time as well. :thumbup:

I'm lucky that I have a daughter who's totally fascinated by this stuff, and we have long discussions about this. Sometimes I tell her something new (to her), and sometimes I learn something new from her. Last week, we went out and took a series to build up an image showing star-trails. Checked out the planets (Jupiter, Saturn, Mars), and the various sights. Was damn cold though (-24C) and fortunately the camera worked find with the Magic Lantern intervalometer while we took refuge in a warm car. Yesterday, she and her boyfriend were at the house for breakfast, and my wife decided to donate my organic chemistry model set, and they spend the next several hours building various molecules. Much better than Lego. Turns out she has a molecule-modeling software on her laptop and they were reproducing the molecules she was studying with the model set.

A had another daughter complain to me about the degree of change around her, and I mentioned that for someone sitting on a piece of slag floating on top of molten rock, she's too concerned about the little details - she was totally freaked out - and tried to expunge the knowledge from her consciousness. Eh. Some are comfortable with the "big picture" stuff, some are not.

And yeah. I got the title "pompous pontificator" at another (non-photographic) forum. :blushing:

He'd be shooting film.

And here I am..... having problems deciding what to make for supper.

Well, that is probably going to create at least a couple hundred parallel universes just by itself.

Personally, I'm going for spaghetti with a bolonese sauce. Simple, easy, and satisfying.

I'm thinking of taking some goulash out of the freezer. That means my other selves are having steak, lobster, caviar, expensive booze, roast duck,..................

You will never know. It can be true.

The simple idea of space itself is so overwhelming to me i just don't care to bother with this sort of thinking.

Easy for us to decide. KC Strip steaks (Bison not beef) and baked pototos on the grill. Of course in the alternate universe my oppisite is probably having Fracnoid City round stead of TaunTaun.


Correction, got home and discovered they are Bison Ribeye steaks, not KC Strip. YumYum.
