any idea how we can go from one D to another D??
maybe jump into a blackhole?
maybe travel to the end of the universe?
maybe use a lot of energy to push an atom into itself so that it turns into nothing?

a vacum is nothing right? nothing is inside a vaccum container. so if there is nothing then what is there? dunno

Can someone explain 8 dimensions to me? They say 7th dimension is a point containing every possible outcome given a certain beginning. Then 8th dimension is joining these two points. What exactly does this mean? Like, in 1D, when you join two points, there is a progression from one point to the other. In 4D, there is some sort of progression through time. But in 8D, what's going on? What does joining the 7D points signify?

I guess what I'm confused about is what is contained between those two points?

I was fine until the 7th dimension, then I started to get confused with all of the infinities. But what the fuck do "vibrating strings" have to do with the 10th dimension. It seems like they just casually throw that word in and pretend like we are supposed to know what a "string" is.

I was also wondering why ichigo was unbanned, people have gotten permabanned for a hell of a lot less than the way he posts.

What was the last non one liner post you made? When was the last post you made that wasn't just some crude insult of someone else?

Lots and lots of vacuum energy yay!

For one reason or another I found that extremely interesting. Thanks for sharing.

Sigh...

What he should make a lot more clear is the thing he hides in the preambe:

"The "theory of reality" that I advance on this website and in the book "Imagining the Tenth Dimension" is not the one that is commonly accepted by today's physicists."

This representation of the 10 space dimensions may be funny to listen to, but it is simply pure bs. Sorry guys... In real physics all the 10 dimensions (and the time as well btw) are on an equal footing, and there is no way you can say that they represent different things. A 10 dimensional space is just a space where you need 10 coordinates to specify a point...

I do not like to rant, but I really can't hold myself back this time:

1) string theory is in 1+ 9 dimensions. So 9 space dimension, not 10 as he states. M-theory, though, an extension of strings, have 1+10.
2) As he tries to describe the SPACE dimensions it is ridiculous that he uses time as one of those dimensions.
3) This concept of intrudcing new dimensions by allowing teleportation from folding has a very high wtf-factor. It doesn't help you understand anything, he could just continue and make abritrarily many dimensions by always allowing this teleportation in his new space...
4) introducing sum over histories (the thing where the guy ends up in different futures) would be not one, but infinitely many new dimensions. Just FYI.
5) To compensate for his idiocy in number 4), he introduces that effect two times: one time for different histories of the guy, and one time for histories of the universe. When you look at different histories of the universe, you would of course inculde all histories of the guy as well...
6) Same thing as 4) and 5), but for the starting conditions.
7) Calling the space of all possible histories of the universe "an infinity" maxes out my wtf-meter. Yes, it is an infinite dimesnional space, you call it an 8 or 9 dimensional space or whatever, but you still call it an infinity by some reason. An infinity is a very interesting thing, but in no way you can compare it to the space of all histories...
8) The 7:th and 8:th dimensions (i think) he introduces are the same one. He just draws the explanation out over two numbers.

And the list goes on, trust me!

If he would have just stated already on the first page that this is bs, not remotely connected to what real scientists think, then it would be ok, but this... Oh, my.... [/rant]

But I like that someone bothered to make a theoretical physics thread. <3

First post here! Couldnt resists.

Cascade kinda knows what he is talking about, he does these things for a living. Im alot less hardcore physicist than he is but even I cringe at some of the statements made. Its very easy to take a concept people cant wrap their heads around and use it to claim all sorts of things.

Its really like a bluff in poker, if you dont know somebody cards he can make them out to be all kinds of things. Until someone calls that is, think thats what Cascade just did.

As my math prof used to say: Imagining higher dimensions is easy. First, you have one dimension. The second dimension is perpendicular to the first one, the third dimension is perpendicular to the second dimension. Now, the fourth dimension is simply perpendicular to the third dimension, the fifth perpendicular to the fourth, and so on....

I prefer the explanation of the lower dimension being the intersection of a higherdimension.
ie, two lines intersect and make a point, 2 squares intersect and make a line, ect.
dimensions really interest me, I have to say if you find an interest you should really read a book called Flatland <written by Edwin A.Abbott 100 years ago>
you can find it here
It gives you an idea of how we would percieve a 4-dimensional shape.
Flatterland is also a good read <expects j/ks of OMG FLATTEST LAND IS NEXT>
it was written by Ian Stewart.

I like some things in M-theory, but not others, but i dont claim to understand it. I find it interesting though.

Edit:i just read my post and decided it sounded like an advertisment T_T;;

Lol don't poke it to death like ...
Just try to imagine w/e his logic is, I'm sure it's flawed like everything else but when I followed his logic I liked it alot, it's a mind bending excercise that makes you smarter
GOGO :D

And requiscat I like that thought about 2 plane int to make line...
Hmmm
Is a curved line in 2 demention or 1? imagine u have 2 curved surface and they intersect but O WAIT 2 curved surface is in the 3rd!
Brilliant!

hey guys, what if we are like the matrix movie??? that would be kool? and the dimensions are just way for the computer to make us see and feel stuff. and like the computer created everything

Can we replace the dot in the 10th demension with something more interesting, like a cheeto.

String theory is one possible explanation to the way things work. Some guy came up with it, and decided that it wasn't completely contradicted by the observable universe. Still I think it's too complicated to be right.

Show nested quote +

That's because you're restricting yourself to three dimensions, thus they don't coincide when you add new dimensions.

omfg .....that really made me laugh....hahahha
quite interessting the thing with the dimensions
