The Existence of A Parallel World

[Abs.]

Parallel universes = You already are super rich in an infinite number of parallel worlds.  You are also dead in an infinite number of parallel worlds.  Same goes with female/married/sick/CEO/pop star/orphan, etc.

[alicetama]

I believe in this theory. It's just... so awesome.

[Sebolains]

seriously though, don't you think it's fascinating to know that there exists a parallel universe

maybe i'm a genius in that world

Not really, since you are you in this universe. They're might be someone who has all your qualities and leads your exact life, except for the fact that they're, you know, a genius, only that person isn't you. That's the biggest issue I usually find with parallel Universe theories. Parallel universes have nothing to do with this universe, they're just a lot like the latter.

For those a bit more curious:

Spoiler:

Basically, as baka1412 pointed out, parallel universe theories (or at least the reality of them) come from probabilities. See: right now our biggest problem is that we have really no idea how big our universe is, either in 3 or more dimensions. Let me elaborate on that:

3 dimensions: It turns out, as you probably know, that the universe was created in the Big Bang, in which basically all the existing matter starting expanding through the... uh... space (that hesitation comes from the fact that we're not quite sure yet what empty space really is, but that's another topic.) The reason we don't know how big the universe is the following: suppose you wanted to know how big your room is. What would you do? Well, you would look and see just where the walls are. From that, you can get a pretty good idea of how big your room is. Now, think that you wanna know how big the Universe is. Well, we'll look. And that's what we did. There's a problem, though. Light, our means to seeing takes time. And in astronomical contexts, it takes a crap load of time. It turns out, that since the Big Bang (ie, since light could have started travelling, ie 13.7 billion years ago) there hasn't been enough time for light from really really far away (more than 46.5 billion light-years away) to reach us. So basically, we know a lot about everything that's 46.5 billion light-years away or less, but nothing at all about everything else. And here is our problem. We don't really know how big our universe is. There has been some estimations, but the truth is that it will always be impossible to prove, because we have absolutely no data from outside out 46.5 billion light-years radius sphere known as the observable universe. Basically, the universe could go on forever, for all we know. And there's a thing about forever (a thing about infinity, actually), it's that in forever, any statistical probability, regardless of how low it is, will happen. So if there's a statistical probability than another star formed X light-years away, which has a planet just like earth going around it, which has people just like us living in it, which have cities, roads, houses, etc. that are exactly like ours, then that will be a reality. This is, to date, one of the two biggest parallel universe theories. In a nutshell, it says: if the universe is infinitely big, then every possibility will happen, and hence there's another universe just like ours, except in it, bluekaitou is a genius.

More dimensions: Oh, my beloved string theory. How many doors for speculation have you opened. The thing about string theory (and believe you me, I barely begin to understand it, so I'm not gonna go into the details, I'm just gonna talk about some of its implications) is that it predicts a crap load of dimensions. 13 + time, to be exact. It actually also predicts that there are god knows how many other big bangs happening in other dimensions, and that our universe was formed only as an example of those. The thing about adding extra dimensions, is that there can be a loooot of stuff the exists, but that we have no way to access it. Everything we know works in a 3+1 dimensional basis. If the universe has a lot more dimensions, and we're just an extremely tiny subsection, we have no way to predict what will exist in those other dimensions. Our physics laws could apply differently there. Maybe, ice melts into fire there. Who knows? The point is, that when you have a possibility for freaking anything to exist, the probability for parallel universes goes waaay up, and so does bluekaitou's IQ, apparently.

Personally, I don't like parallel universe theories. Call me egotistic, but I like thinking that our situation is unique. However, I do understand that they could be a very real thing.

Kick out? No way. It's really interesting.

From a documentary online about Einstein and the string theory, it just happened to be math that works with the current view of physics. There's not much to say it's right or not. And the ugly part is that the rest of the dimension (outside the 3D and time part) are tiny circular loops that are smaller than the smallest particles. Wonderful math, but absolutely can't be tested with our technology.

im a high school student (not detective,not shrunk) and im one of the best students at math there, ive always liked math but really, how can math says that there are tiny circular loops and so and so??? they're numbers...........

this is somewhat akin to asking how physics determines the path of a ball thrown at 65 degrees through the air at 50mph, because after all, that's numbers as well.

I don't claim to know the math behind string theory, but the point of science  is to describe the world, and without math it wouldn't be able to do any of that. So, though they may be "just numbers", those numbers are what have helped us discover almost all facets of the natural world, so to wonder why they can't determine something that's just on a somewhat smaller scale is somewhat silly imo.

[Akonyl]

It describes stuff much like y=mx+b describes a line, or x^2+y^2=r^2 describes a circle. Of course, this is oversimplifying things, but these rules can be extended beyond 2d graphs and can then be used to model various things (like current systems and magnetic fields) in 3d.

I'm not the best at explaining things, but basically, if you want to find out how, stay in school until you learn the more advanced concepts.

And then if you don't see how, you can take actual physics courses and hopefully make things more apparent.

[bluekaitou1412]

Well maybe, the parallel bluekaitou1412s are a lot better than the bluekaitou here. So what if we find a way to cross between those parallel worlds?

It's scary to think that at least in one of those parallel worlds, no bluekaitou1412 exists...

NOW I JUST WANNA TALK ABOUT TEMPORAL PARADOX

DAMN YOU, TRC!

i understand that math can measure and estimate stuff, but how does it describe these stuff? i  mean, i keep reading that math can describe almost  anything, how is that so??

Eh... that's a lot to explain, you know... maybe you can research for yourself?

[blurfbreg]

You can make mathematical models (most of it is calculus). For example, you can graph the population of wolves and rabbits in a forest.

So, though they may be "just numbers", those numbers are what have helped us discover almost all facets of the natural world, so to wonder why they can't determine something that's just on a somewhat smaller scale is somewhat silly imo.

The strange part was that... the math was developed just for fun, non-applicable purposes (by Euler, who was not known for this math) and someone took them and applied them to the world. After a LOT of tweeking with the equations that define the (originally) 10 dimensions as bands of strings so that the equations fit with the laws of physics that we know so far, they did even more work to make it 11 dimensions.

In Doctor Who, not everything is unchangeable. While some points in time are fixed points and can't be changed, there are also points that are called "in flux" and can thus be changed. After all, time is pretty timey-wimey. You shouldn't look to Doctor Who for actual science, if that's what you're thinking of doing.

That's for BK so that we're back on-topic in the off-topic zone. Of course it's not real. Just any other theory, like all sci-fi (for now).

perhaps "actual science" wasn't the best word, I just mean that doctor who makes pretty much no attempt to consistently explain things, and was correcting the notion that in Doctor Who, you "can't change the past".

[sstimson]

Well in science we have equations like below

P=Hdh/dt + Zdz/dt + Ydy/dt + Xdx/dt + TdT/dt * a Constant

definding at one point P(H,Z,X,Y,T,) at t Time. P being Pressure, H being density, X being air movement in the X direction, Y being air movement in the Y direction and T being temperature d(?) means the change of ?, dt means change in time

in a way this is SIX dimensions

I think it'd be cool. (Someone here is watching too much Reborn! and TRC)

I think it's possible,, given that (It'll take awhile to load completely, like at least 2 mins)

Then these solar systems together called galaxy,groups of galaxies spread across the universe, for all we know, there are universes spread across who-know-what...

It really is impossible there are no worlds connected to us, but it's possible these worlds realized how stupid earthlings are and decided to never communicate with us
