personaly i think its as rediculas as the god theory but then again lots of people believe in that, the multiverse theory is that every decision anyone makes creates a new universe to play it out.

Actually it would have just as much to do with what you decided to have for breakfast this morning as it has to do with the randomness of quantum events.
Basically, every possible collapse of a probability wave has the potential of becoming, until it collapses into a specific state, which renders all other states impossible.
It's hard to put into laymans terms the complexity of trying to imagine how every possible outcome of every quantum event actually obtains in different universes, or 'worlds'.
Let's do a thought experiment.
Imagine you're in a room with a radioactive substance. Over a period of 1 second, you count the particles emitted by the substance, and you record, say, 324.
Now imagine you somehow managed to go back in time and watch yourself do the experiment. You would see yourself counting 324 particles, right? Wrong. Due to the randomness of events at the quantum level, you might see yourself counting 323, or 325, or even 400, or even none at all!
So even though you are witnessing the same event, it has happened completely differently. But wait a minute, if you remember counting 324, thats what has to have happened right? Yes, in YOUR timeline, or world, you counted 324. But when you went back in time and watched yourself do the same experiment, the OTHER YOU counted a different number. This doesn't make sense at all in our accepted view of the (single) universe, but it makes perfect sense in the many worlds view.
You see, when you did the experiment, you counted 324. But the 'other you' counted, say, 325. How could this happen? What happened to the original event? Well, it exists in its own universe, or world. You left that universe and travelled back in time to the universe where the other you counted 325. What happened to the universe you came from? Well, it either no longer exists, or it now co-exists with the universe you are now in. Confused?
The many worlds theory has been used to suggest a solution to the bizarre wave-particle duality of light. Take the famous slit experiment for example- (I assume you're familiar with it)
If we shine a beam of light at a sheet of cardboard with two slits cut in it, the light passes through the slits and interferes with itself on the other side to produce bands of light and dark, where the crests and troughs of the 'waves' meet each other. But if you fire a single photon and it goes through only one of the slits, it still falls only in areas where it would fall if it was undergoing interference, even though there are no other photons available for it to interfere with.
On explanation for this is that the photon is in fact interfering with other versions of itself in alternate universes. When we fired the photon at the slits, there was an equal probability that it could go through either slit, so in other universes, the photon might go through the other slit. Some of the 'other photons' therefore went through the other slit, and interfered with the photon in our universe, causing it to behave as it would when interfering with other photons in the same universe.
Yeh, its a complicated one. But think about it too much and it'll keep you awake at night :(
I, for one, find the many worlds hypothesis to make the most sense.

I've never heard any scientific person say every decision I make creates a new universe. That's not the multi universe hypotheses. What you are saying is some kind of human ego thing, thinking a human could make a decision and create another universe.
The multiple universe hypotheses is about parallel universes existing in other space/time dimensions. It has nothing to do with what you decided to have for breakfast this morning.

I think it's relatively silly. First we have trouble understanding
our universe, then we add a bunch more to explain it. It's like
the world rested ont the shoulders of a man, who was standing on a turtle, etc.. I say forget multiverses, it's turtles all the way down babe!

Actually, it has more validity than the God theory,as it supports results from Quantum theory that other theories do not-it doesn't mean that the God theory is not true though!
It is a theory that has logical validity, therefore I buy into it until it is disproved, or replaced by a better model.

Funny you should ask. I was thinking about this recently. Ultimately, it's just a theory, most likely never to be proved or dis-proved.
Interesting though.

Well it's as good as any other theory that our little head encased lumps of pink goop can come up with until we can really understand what's going on.

It is a lot of people playing with equations with no experimental support and nothing but ideas that have never been verified. I have not bought in yet

If you were to create a miny universe in a lab (bear with me)
It would grow at a continual rate but never take up any space. It would co exist.....I think.....

Multi-verse is the only way to alleviate the paradox of traveling in the past (altering the past etc..). Since I would like that to be possible, I would therefore like that multi-verses are true.

No, as n dimensional spaces remain projections of higher ordered events and yet share a common null...
