Scientific conundrum... or not ?

Question

Let's assume that the multiverse theory is correct.So we have an infinite number of universes. If we embark on a journey through hyperspace, and suddenly emerge out of hyperspace, what's the chance for us to get out in a specific universe ? 100/oo does not resolve this question, as no number can be divided by infinity.
Also, regarding H.G Wells book "Invisible man", Michio Kaku stated that he was invisible due to the fact that he was in a universe just above our own (in 4D), and that light passed beneath his universe. How can that be possible ? There would be an infinite number of universes between the two, as 0+0=0.

Answer 1

Not a conundrum (although interesting question).



Whether you postulate a multiverse model to to account for quantum indeterminancy (a new universe is born at every quantum decision) or to account for membranes colliding into each other, or any other theoretical impulse to invent more than one universe the amount of universes in the multiverse never reaches infinity.



They may reach a number incredibly large however. This is crucial because the hyperspace jump paradox (at beginning of your question) and pseudo-zeno paradox (at end of your question) both cease to become conundrums when you are dealing with a quantifiable, rational number (rather than an infinite one).

Answer 2

I think you are confusing universes with dimensions.

In the case of the invisible man, he is able to

disappear into a higher dimension (the fourth,

which is not perceivable to those of us stuck in

three dimensions). Think of the case of a flatlander living in two dimensions. Someone like you who could move in a third dimension would seem to shrink down into a point, and then disappear from his world just by changing position.

There are certainly theories about our universe having higher dimensions than the ones we see.

And if they exist, then we move through them all every time we move. The trick is to learn how to expand them to make them usable for transportation. Then we would have to learn to navigate thru them to figure out how to end up where we want to. But when we emerge from that hyperspace, we would still be situated somewhere within the same universe that we started out in. That is the basis for any type of

"hyperspace" travel we might someday be able to do. But that hyperspace would exist WITHIN

the higher dimensions that are already present within THIS universe.

The multiverse theory maintains that there are other universes that exist along side this one.

But these are completely independent universes, totally sealed off from any other. Each one would have its own number of dimensions, its own hyperspace connections internal to it. Higher dimensions within one universe would have no connection to any other, nor any way to reach any other. By definition, a

"universe" contains everything within itself.

Answer 3

The "multiverse" theory is just fantasy, not a real scientific model that can predict anything. So the chances are whatever the writer of the fantasy wants it to be. If the story uses words like "pentagram", "Sim Sala Bim", and "true name", then it is magic fantasy. If the story uses words like "photons", "multi-bean phasor" , and "interdimentional" then it is science-fiction fantasy. Both ways, it is still fantasy.



The technical name for this in writing is "hand waving", as in what a stage magician does. H.G. Wells was a master at stringing words together. If he chooses to write about a "universe" that is "above" our own, that's fine with me. He could just as well have said that Kaku was invisible because his true name was inscribed in a blue pentagram, but that would have made the story into a magic fantasy.

Answer 4

If our universe is hyper spherical,then we wouldn't ever be able to get out of this 3-D world, as the spherical universe would redirect us to the same point,like moving in a circle,and detecting higher dimensions of space-time wouldn't be possible.The idea of multiverse can't be denied.It could occur by the overlapping of the fabric of space-time, forming higher dimensional worlds.Our world is made up of matters, and for every matter there has to be an anti-matter like a positron for an electron.Anti-matter worlds are thought to exist and said to be residing in the parallel universe.It's thought to have exact but opposite fingerprints of our world.If we ever meet our anti-human look alike and shook hands,we would annihilate to explode,obeying the law of conservation of energy.That sounds like a science fiction though.

Einstein once said that "As far as the law of mathematics refer to reality,they are not certain and as far as they are certain,they don't refer to reality."He was referring to the predictions of quantum physics and string theory which were hard to visualize in reality but had a mathematical certainity.
