    Fourth Dimension: Visited by Aliens?

    So my question is (and this is aimed at cmdrsponge so please reply after he has thank you) What is the fourth dimension? Where is the Fourth dimension? Are the Fourth dimensional aliens going to hunt me down and kill me for asking to many questions?

    A theory for a FIFTH dimension .

    a theory for a FIFTH dimension... All this talk about dimensions I am sure has bored a number of you, although here is another theory! (If it has been thought of before, I apologise!) Bearing in mind 'time' is established as the 4th dimension, it occurred to me that there must in turn be a...

    Why the 4th dimension was created

    So we start with the singularity having lots and lots of mass in it. Now this is too much mass so it pops open into the 1st dimension so just a lot of mass covering a line. Since there is no concept of time that means all this mass covering the line exists over and over again making and...

    Fractals of rational dimension and fractals of integral powers

    What generalizations can be made concerning fractals of nonzero rational dimensions M/N (where M and N are nonzero integers)? How does a fractal of non-integral dimension F compare geometrically to a fractal of dimension GF, where G is a nonzero integer?

    What would life be like in the fourth dimension?

    I would like to start off by introducing myself, my name is Jonathan Ploegman from Long Island, New York. I am 18 years old and I am new to the physics world, however I am very interested and eager to learn all that I can. I was wondering what life in the "fourth" dimension would be life. I...

    Time as a Spatial Dimension: Is It Possible?

    I came up with an idea more than a year ago, but I've yet to take a physics course, still in high school, but please bear with me. Take the Kaluza-Klein approach that light originates from the 5th spatial dimension, at the nearly unreachable Planck length. Now, light is supposedly a vibration...

    How Can a Hyper-Tesseract Explain High-Energy Particle Tunneling?

    I have been able to visuallize what a tesseract and its propperties look like. I then applied the same principal to a tesseract and came up with a hyper-tesseract with phase properties (the ability to access other planes of existence). Is this a possible model for mathematical explanation of...
