Forgive me for asking, but if the “universe” consists of all matter, energy, and space that exist, how can there be a “parallel universe”? Wouldn’t it be more accurate to say they believe there are parts of the universe that have not yet been discovered?
No. The generally accepted use of the term "universe" is "all the matter and energy in this Big Bang". It's everything we can see and measure and trace it's origin back to "the" Big Bang.

Other universes -- other Big Bangs -- are not observable and are outside our "universe".

The whole collective of universes (whether "parallel universes" or "alternate Big Bangs in an Eternal Inflation") are described as the Multiverse (or, by Guth, as the Cosmos).

I’m guessing that was September 1958... is that right?

There is another alternative universe out there in which everything happened exactly the same since the beginning of time except that I did not respond to this post.

How could we, in this universe, ever “see” or “detect” another universe, let alone many others? Unless we can so detect one , then this whole thing will always be a theory.

Now you're really getting into sci-fi territory.

1. A number of the theories used to explain the apparent conflict between relativity and quantum mechanics depend on the "other universe" or "hidden dimensions" theories. It is possible to make predictions based on these theories whereby the not observable things would affect things we can observe. Experiments could potentially prove or disprove these predictions.

2. Some have proposed that at very high speeds or gravitational levels (black holes) it might be possible to "turn sideways" and pass into another universe or at least be able to observe it or its effects.

I have no idea whether any of this is possible. I'm just leary of using the terms "always" and "never" when talking about possible future science.

Best critique of these guys I’ve seen.

I can’t afford to live in a parallel universe. All I can afford is a parallel zip code.

I used to think there were an infinite number of alternative universes. Thus everything that can happen does happen and, furthermore, happens an infinite number of times. However, with this rather small limit of 10^10^16, not everything can happen and certainly not an infinite number of times. So I might not be in clover anywhere. This may be as good as it gets. :-(

We need to find a way to travel to other universes.

Just move all of the decent folk to a Universe where humans never existed and leave the socialists and islamists to each other throats.

If crazies ever arise in the new universe send them back “Home”.

Plus the alternate earth will have vast untapped deposits of oil and minerals and no indigenous folks there so the liberal attitude of “blame America for the rest of the world’s suffering” would never exist there.

Sounds like Paradise! I am sure God would want us to develop “Sliding Technology”

We could move Israel (Whole country and infrastructure including 10ft of topsoil so they have the holy land in the new universe)into a the same world or another one as then they wouldn’t have to deal withe crazy nutbags in the Middle east.

Mazeltoff!

(Of course this Multiple Universe stuff sounds like something off of Fringe)

I'm with you. Ever since I heard of the universe constantly branching off into new universes, I've been trying to figure out how to steer my way onto branches where only good things happen from now on out.

I mean, when the universe splits, we personally branch off too. A copy of us goes down the good branch and a copy goes down the crappy branch. Why does this particular consciousness that is me always go down the crappy branch where, for instance, we were defiled with knowledge of the Clintons, Iran ended up with nukes and a Kenyan became president? That's a gross simplification, of course, but you get the idea.

No sirree, it's time for us to seize the bull by the horns and only steer ourselves down happy branches from here on, all the way to Utopia. No more rallies. No more voting. I'm just gonna take a short cut.

There's another one like it, same source I think, and I plan to steal it too. Here's the newest of the String Theory Ping List messages.
