The Appropriate Mathematics to Explain Cosmos(Physics) In my first article Mathematics In the Eyes of God, I think that the mathematics people used to explain cosmos（physics）might somewhat deviate from the real cosmos(physics). Let’s talk about a straight line in cosmos. People have two opinions. First, in an open space, people say a straight line extends faraway in two directions , just go. Second, in a close space, a straight line extends in two directions and meet together at the infinite point at last, the so-called extension line. Which is the real straight line in cosmos? Suppose that it is the second one. Next, let’s see what will happen. In order to represent a point on an extension line, we use homogenous coordinate, (X1,X2). The relation with open space straight line is X=X1/X2, so the speed relation is X’=(X1’X2-X1X2’)/X2²，because X2 is a constant, soX2’=0. then X’=X1’/X2. We get the homogenous coordinate speed relation equation V=V1/X2. Next, let’s see what will happen if we put it into the mass-speed equation in Special Relativity. We arrive at the homogenous coordinate mass-speed equation: Result 1: it is possible thatV1 exceed C. Result2: cosmos is parallel possibly. One X2 value represents a certain world. If X2=1,this is the matter world we are familiar with . Next, try to use it to explain some physics problem. Subject1: the particle – wave duality. If X2=1, it is the matter particle. If X21+X22+……X2n=1, it might be the probability wave. Subject2:if X2＞1, we can explain why photon can move with the speed C and it’s mass does not rise to infinite. Next let’s see the mass-energy equation, it change to be: What will happen to physics if this mathematical method is launched?

At first I thought I was perhaps just not understanding, but when HallsOfIvy posted his rebuttal, I concluded that perhaps it is not my failure... While HallsOfIvy might be blunt, he is usually pretty astute. __________________ ~\o/~  Apr 2nd 2018, 08:53 AM #4 Senior Member   Join Date: Aug 2010 Posts: 434 Well, what if the post had been about "the gap between physics and French" or "the gap between physics and art"? While mathematics is used in physics (as is French and, to a lesser extent, art) they are completely different things and it makes no sense to talk about a "gap" between them. When I first read the title, I thought the post might be a reasonable discussion of how one chooses a mathematical model for a physical situation and the errors that can result. Unfortunately, all the post had was mysticism about some perceived mystical connection. topsquark likes this.  Apr 2nd 2018, 10:25 AM   #5

Perhaps my problem in understanding what you are trying to say is that none of your equations are visible. Still, a couple of comments:
Result 1: Then we are not talking about the Physics of our Universe.

Subject 1: What do points on a "straight" line (geodesic?) have to do with Quantum Mechanics??

Subject 2: Photons do not have a mass so we don't have to worry about the mass of a photon being infinite.

What would happen to Physics? A lot of weird things. We would first have to address what happens to Special Relativity (v > c). Such a thing changes the geometry of space-time and you would have to have some kind of specific property in order to define things like the metric, for example.

Next, lets calculate the differential quotient against X2. Pay attention please, not against time t. Here X2 is a variable quantity. X=X1/X2 So, dX/dX2=(X2dX1/dX2-X1dX2 /dX2)/X2²= -X1/X2² = -X/X2 So, X = - X2dX/dX2 Also, X = ∫Vdt We arrive at ∫Vdt = -X2Vdt/dX2 suppose V a constant for convenience So t+c = -X2dt/dX2 So ( 1/(t+c)) dt = - (1/X2)dX2 Here c is an integration constant, ∫(1/(t + c))d(t+c) = -∫(1/ X2)d X2 ln(t+c) = -lnX2 t = exp(-lnX2) for convenience we take c = 0 and only talk about the positive value of X2. When representing a point in the three dimension space, the homogenous coordinate is (X1,X2,X3,X4) , the symbol of the real fourth dimension change from X2 to X4. And the equation above change to be : t = exp(-lnX4) We can see X4 is a real fourth dimension of cosmos, and time t is not imagined by people. It has real number corresponding relationship with X4 . So X4 and time t are both real fourth dimension of cosmos.

the nature of the fourth dimension

Understand the nature of the fourth dimension, people understand the cosmos.

Any kind of line is one dimensional and a straight line can only go in one direction.
