Force and Spacetime Equivalence

In summary, according to the principle of equivalence between inertial mass and gravitational mass, Einstein was able to formulate his general theory of relativity. This principle states that the geometry of spacetime is the same for all forces, including the classical forces of gravity and electromagnetism. The two geometries that can be formed are the doubly twisted Moebius strip and split or tear thru the middle creating two loops that are linked together. This principle of directional invariance means that two distinct strips cannot be transformed into each other. This equivalence is important for the study of their geometrical structures in spacetime without the use of the calculus of tensor. Additionally, the square of energy, E, can be described with the help

The Principle of Equivalence between inertial mass and gravitational mass used by Einstein to formulate his general theory of relativity is a prelude to another equivalence principle.

This is the equivalence between a fundamental force and the geometry of spacetime.

The forces used in this discussion will only be the classical forces of gravity and electromagnetism. The weak and strong force will not be discussed at this time.

The following classical forces are denoted by their respective symbols. [itex]F_E[/itex] for the electric force. Magnetic force is denoted by [itex] F_B[/itex], The gravitational force is [itex] F_G [/itex], the inertial force is [itex] F_I [/itex].

[tex] \vec{F_E} = q \vec{E} [/tex]

[tex] \vec{F_B} = q \vec{v} \times \vec{B} [/tex]

[tex] F_G = G \frac {m_1 m_2}{r^2} [/tex]

[tex] \vec{F_I} = m \vec{a} [/tex]

The equivalence between [itex]F_I[/itex] and [itex] F_G [/itex] is what Einstein did. But it can shown that it is also possible to establish the equivalence between [itex] F_G [/itex] and [itex]F_E [/itex] with [itex] F_B[/itex].

There are two distinct relationships that are equally important and must be taken for the study of their geometrical structures in spacetime. These can be done without the use of the calculus of tensor.

[tex] F^{-}_G = F_E - F_B [/tex]

and

[tex] F^{+}_G = F_B - F_E [/tex]

Because of the minus sign between the electric force and magnetic force, the spacetime geometry can appear to be hyperbolic in contrast to Euclidean, spherical or elliptic geometry. But the true geometry is none of the above.
 
  • #6
The spacetime geometry is that of a doubly twisted Moebius strip and split or tear thru the middle creating two loops that are linked together. With the principle of directional invariance, two distinct strips can be created that are not topologically equivalent. That is to say they cannot be transformed into each other.
 
  • #7
If we are restricted to just one dimensionality of these Moebius strips, we can form two types of Hopf links that are not topologically transformable into each other. One of these two Hopf links can be the seat of the force of gravity, [itex] F^{-}_G [/itex] and the other the force of antigravity, [itex] F^{+}_G [/itex].

If the electric force dominates the magnetic force of the vacuum then

[tex] F^{-}_G = F_E - F_B [/tex]

if the magentic force dominates the electric force of the vacuum then

[tex] F^{+}_G = F_B - F_E [/tex]

If infinitesimal lengths of r's are introduced together with the forces of electricity and magnetism of the pure vacuum, the true quantum of square of energy, E can be formulated.

[tex] E^2 = r_E \times F_E \cdot r_B \times F_B [/tex]
 
  • #10
By switching the position of r and F in one of the two outer products, it is also valid for the square of energy to be given by:

[tex] E^2 = F_E \times r_E \cdot r_B \times F_B [/tex]

When these are expanded by Lagrange's identity the following squares of E are valid.

[tex] E^2 = (r_E \cdot r_B)(F_E \cdot F_B) - (r_E \cdot F_B)(r_B \cdot F_E) [/tex]

and

[tex] E^2 = (r_E \cdot F_B)(r_B \cdot F_E) - (r_E \cdot r_B)(F_E \cdot F_B) [/tex]

No matter how many switches of the positions of r and F, these are the only two possible forms of the square of E. One represents positive (real) polarity of energy and the other represents negative (imaginary) polarity of energy depending on whether

[tex] (r_E \cdot r_B)(F_E \cdot F_B) = 0 [/tex]

If r is four dimensional then [itex] r_E \cdot r_B [/itex] can be interpreted as the spacetime interval.

if the electric force and the magnetic force are orthogonal then [itex] F_E \cdot F_B [/itex] vanishes.

Although [itex] r_E [/itex] and [itex] F_E [/itex] must always be orthogonal (same thing with the B's), the angle between [itex] r_E [/itex] and [itex] F_B [/itex] varies from 0 to 360 degrees.
 
  • #12
Conclusion:

The equivalence of force and spacetime occurs at either of two independent conditions:

1. When [itex] r_E \cdot r_B = 0 [/itex].

2. When [itex] F_E \cdot F_B = 0 [/itex].

or both.

The two true quanta of square of energy will now be denoted by:

[itex] H^{+}[/itex] and [itex] H^{-}[/itex]. These are symbols for two types of Hadamard matrices. With these matrices and their generalization to higher order, the geometrical structure of positive and negative electricity can be described. And the experimental values of the mass can also be described. This description and by the use of abstract algebraic rings and the Abelian group of matrix addition operator and semigroup of matrix multiplication, makes a Theory of Quantization for one dimensional Space (TQS). This theory, TQS, at the least, can removed the mystery behind the mass ratio of an electron to that of the mass of the proton as determined by experiments to be 1836. TQS predicts a value 0f 1832 which error is less than 1 percent of the experimental number.

The central domain of Einstein's special and general theories of relativity is to give the justification to why

[tex] r_E \cdot r_B = 0 [/tex]

The central domain of quantum mechanics is to give the justification to why

[tex] F_E \cdot F_B = 0 [/tex]

And finally the task of quantum gravity is to justify both conditions.
 
  • #15
When both conditions are satisfied then the r's are equivalence to the wave functions of quantum mechanics and the F's are equivalence to the linear momenta and the square of energy is given by:

[tex] E^2 = \psi_i \times \phi_i \cdot \psi_j \times \phi_j [/tex]
 
  • #16
The question now is to ask: "can some certainties be recovered" from the square of energy? Or becoming even more uncertain?

Heisenberg's uncertainty principle is given by the products of conjugate variables of position and momentum or energy and time.

[tex] \Delta \psi_i \Delta \phi_i \geq \frac{h}{2 \pi}[/tex]

[tex] \Delta E \Delta t \geq \frac{h}{2 \pi} [/tex]
 
  • #17
But the square of the uncertainty should become more certain.

[tex] \Delta E^2 \Delta t^2 \leq \frac {h}{2 \pi} [/tex]
 
  • #18
The physical meaning of the difference of the square of time must now be clarified.

What is [itex] \Delta t^2 [/itex] ?

Does this implies there are two directions of time?
 
  • #19
If [itex] \Delta E^2 = \Delta F^2 \Delta \psi^2 [/itex] then [itex] \Delta \psi^2 \Delta t^2 [/itex] is the spacetime interval.
 
  • #20
This shows that the physical meaning [itex] \Delta t^2 [/itex] is equivalent to the square of the linear momentum, [itex] \Delta \phi^2 [/itex] when mass is still not clearly defined.
 
  • #21
When time is a vector, then [itex] t^2 = t \cdot t [/itex]. This vanishes when the two time directions are orthogonal. The scalar (inner) product of t is given [itex] t \cdot t = |t||t|cos \theta [/itex].

Also the vector (outer) product of t is given by [itex] t \times t = |t||t|sin \theta [/itex]. if [itex] \theta [/itex] is 90 degrees then [itex] t \times t = t^2 [/itex].

I wonder if the vacuum energy of 10^120 Joules/m^3 could be made nearer the experimental value of 10^ - 9 J/m^3 if negative time and energy could be associated with Heisenberg's relation e x t.
 
  • #24
Sorry, I still have not reach a point where I can plug-in numbers to do any calculation. But except for the Hadamard matrices for calculation of mass-ratios and electric charge after the facts which is not really predictions.
 
  • #25
When time is a vector, its directionality can be determined by its scalar and vector product.

If time has only one direction, its scalar (inner) product is always [itex] t^2 [/itex].
 
  • #26
The magnetic force of the vacuum is equivalent to a timelike force and the elctric force of the vacuum is equivalent to a spacelike force. These two forces are interlocked and manifested only as electromagnetic force of the vacuum. But in the existence of matter, these forces can be separated. This separation is the same as symmetry breaking.
 

What is force and spacetime equivalence?

Force and spacetime equivalence is a concept in physics that suggests that the effects of gravity and acceleration are equivalent. Essentially, an observer in a uniform gravitational field would experience the same effects as an observer in an accelerated reference frame. This idea was first proposed by Albert Einstein in his theory of general relativity.

How does force and spacetime equivalence relate to the theory of general relativity?

The concept of force and spacetime equivalence is a fundamental aspect of the theory of general relativity. In this theory, gravity is not seen as a force between masses, but rather as a curvature of spacetime caused by the presence of mass and energy. This curvature affects the path of objects in the same way that acceleration would in a non-gravitational scenario.

What are some examples of force and spacetime equivalence in action?

One example is the phenomenon of gravitational time dilation. This is the slowing down of time in a strong gravitational field, similar to how time would appear to slow down for an observer in an accelerated reference frame. Another example is the equivalence of inertial and gravitational mass, which is why all objects fall at the same rate in a vacuum, regardless of their mass or composition.

How is force and spacetime equivalence tested and confirmed?

Force and spacetime equivalence has been tested and confirmed through numerous experiments, such as the Pound-Rebka experiment and the Hafele-Keating experiment. These experiments have shown that the effects of gravity and acceleration are indeed equivalent, providing strong evidence for the validity of this concept.

What are the implications of force and spacetime equivalence?

The concept of force and spacetime equivalence has had a profound impact on our understanding of gravity and the universe as a whole. It has also led to important technological advancements, such as the development of the Global Positioning System (GPS), which utilizes the principles of general relativity to accurately measure time and distance on Earth.
