I work with "n" dimensions in Linear Algebra :dance: I know it's an euclidean space, btw.
[QUOTE=Agoat;21846418]12 if you count my nose[/QUOTE] Why did I laugh? I AM SPHERIUS. PERSONALLY I FIND THE IDEA OF A FOURTH DIMENSION UTTERLY PREPOSTEROUS [IMG]http://msnbcmedia.msn.com/j/msnbc/Components/Photo_StoryLevel/071203/071203_spherius_cosmiclog_12.standard.jpg[/IMG] ARTHUR SQUARE [editline]07:46PM[/editline] [QUOTE=JohnnyMo1;21855872]Yes. It does travel in a linear path. Except the path is curved because the space it's traveling in is curved.[/QUOTE] No. Imagine you throw a football really fucking hard. If the angle matches exactly the curvature of the earth, it will "orbit" it without flying out into space or crashing back into earth. To curve something as big as the earth needs something black wholish in size. I think I /thread
[QUOTE=JgcxCub;21886680]Okay. Define spacetime, someone who actually understands it.[/QUOTE] Spacetime is a combination between the dimension of space (1,2 and 3) and time (4). In the same way that you don't call 3D space by its individual direction because you can freely between them, spacetime has become one word to show how they can be treated as 4 equal dimensions within a single 4D space. The only reason we see time differently to the other three is that we are constantly traveling one way through it, and only seeing a stream of 3D "cross-sections" of space (we don't yet know why this is. Time should in theory travel both ways). As shown earlier in this thread, weight bends spacetime, stretching both space and time like a rubber sheet. All objects follow a linear path in spacetime, but we see this as a curved path in space.

[QUOTE=JgcxCub;21958615]So please tell me how you can [I]bend[/I] a dimension?[/QUOTE] Depends if you mean how to visualise it or how it physically happens? To visualise it, imagine a ball on a duvet. It will roll along it in straight lines if pushed. Now if a bowling ball is placed on the duvet. The ball will roll along the duvet, then roll towards the bowling ball. It is still moving in a straight line along the contours of the duvet, but to a 3D observer it has curved in its path. As for physically "how", that it what the LHC is trying to discover, to an extent. The nature of mass and why it has a displacement.
