  • This is not an Alternative Gravity talk.
  • PURPOSE
  • 1) Present arguments for the electrical effects
    of
  • i) Time Dilation
  • ii) Redshift
  • iii) Spacetime Curvature
  • (Currently these effects are believed to not
    exist independently of Gravity)
  • 2) Show that the Special Relativistic
  • Electromagnetism is an approximation to an
  • exact General Relativistic Multi-Metric
    Theory
  • 3) Present the implications of this resulting
    theory

3
  • The Gravitational Arguments for the Time
    Dilation ,
  • Redshift Spacetime Curvature will be
    adapted
  • to Static Electric Fields.
  • Argument 1 Consider two identical atoms at
    different
  • potentials in a Gravitational Field two
    identical
  • charged atoms (ions) at different potentials in
    an
  • Electric Field separated by a distance H.


4
  • When the atom at the origin is in an excited
    state
  • with an excitation energy E0 its total
    energy is

Gravity
Electricity
  • When the photon emitted by this atom is
    absorbed
  • by the atom at position H, its energy
    becomes
  • The fractional difference in the atomic energy
  • levels of the two atoms is

5
  • The energy levels of the absorber atom are
    blueshifted (irrespective of Q) in Gravity, and
    for positive Q in Electricity in the laboratory
    frame
  • Eq. (1) describes the difference in the rates of
    atomic clocks located at a height H one above the
    other.
  • (For Gravity L. B. Okun, K. G. Selivanov,
    Am. J.Phys. 68 (2000)115 )

A positively charged atomic clock runs faster at
points of higher electric potential than
at points of lower electric potential.
6
  • The photon emitted by the absorber atom will
  • appear to undergo a Redshift for positively
  • charged atoms

It is essential to note that the photon is
electrically neutral or that it has no
effective electric charge has nothing to do
with the Electrical Redshift.
We propose a Pound-Rebka-Snider experiment in an
electric field with ions to verify Eq. (2).
7
  • Argument 2 Pendulum Clocks suffice to detect
    the
  • existence of the Time Dilation both in Gravity
    Electricity
  • Let us treat the Gravitational Case First
  • Consider two identical simple pendulums of
    length
  • L located vertically at z0 and zH.
    The periods
  • of the lower and upper pendulums are given
    by

Gravitational Time Dilation (with a
wrong magnitude)
then
8
  • Let us adapt the gravitational case to
    electricity
  • Consider a Charged Simple Pendulum above a
  • charged sphere. The period of the pendulum
    is

9
Predicted times elapsed after 105 oscillations
of a charged simple pendulum with L25 cm, m100
g, r1cm, in the downward electric field produced
by a metallic sphere of R12.5 cm, V(R) -105 V.
A positively charged pendulum (clock) runs
faster at points of higher electric potential
than at points of lower electric potential.
This is the Electrical Time Dilation
10
  • Use the last part of Schilds Argument
  • Two Photons are emitted by the charged clock at
    z0
  • which are absorbed by the charged clock at
    zd in an
  • electric field. The emission absorption
    time intervals
  • are not equal.
  • A parallelogram with unequal opposite sides
    cannot be
  • realized in Minkowski Spacetime.
  • Spacetime must be curved in the presence of an
  • electric field.

Charged pendulum clocks provide an experimental
proof for the Electrical Time Dilation
Spacetime Curvature
A Pound-Rebka-Snider Experiment must be done, too.

Argument 3 Adapt Torrettis Gravitational
Argument (R. Torretti, Phys. Perspect. 2 (2000)
118)
  • Consider a charge distribution concentrated at
    a point. The electrical field around such a
    charge distribution is nonuniform.
  • Move from one field line to the other and come
    back to the
  • original point by making a 3600 rotation.
  • Cover all the field lines in 3 dimensions.
  • The set of points obtained this way constitute
    the two
  • dimensional closed surface S2.

Differential Topology The set of all rays
emanating from a point is a representation of the
manifold S2. (Gravitation, Misner, Thorne,
WheelerSec. 9.7)
12
  • Argument 4 The Electrical Redshift/Time
    Dilation can be
  • Inferred from a Principle of Equivalence (PE)
    for the Electric Field.
  • Note that The Gravitational PE has been stated in
  • different forms some of which are extraneous
    and wrong.
  • The statement There is no local experiment that
    can
  • distinguish a uniform gravitational field from
    a uniform
  • acceleration is
  • extraneous in that it is not required for the
    equivalence
  • of uniform acceleration and gravitational
    field at a point,
  • incorrect. (An electron in uniform acceleration
    radiates while it
  • does not when it is at rest or moving at
    constant velocity in a uniform gravitational
    field S. Parrot, Found. Phys. 32 (2002) 407)

13
  • We adapt R. C. Tolmans definition
    (Thermodynamics and
  • Cosmology, Dover Publications, Inc. 1987) to
    electric fields
  • Replace gravity by electricity in the definition
  • It is always possible at any spacetime point of
    interest
  • to transform to coordinates such that the
    effects of
  • electricity will disappear over a differential
    region in the neighborhood of that point, which
    is taken small enough so that the spatial and
    temporal variation of electricity within the
    region may be neglected.
  • The equation of motion for a charged particle
    moving
  • freely in an electric field E is

mi inertial mass, q electric charge
14
  • The transformation


transforms Eq.(3) to
  • Hence, the electric field in the vicinity of
    the particle
  • has been cancelled.
  • Uniform acceleration is equivalent to charge
    to mass
  • ratio times the electric field.
  • The resulting General Relativistic theory will
    be a
  • Multi-Metric theory.
  • Now consider a cabin or a spaceship uniformly
  • accelerating at
    in a region devoid of
  • any kind of fields.

15
  • A photon emitted at t0 by an emitter is
    absorbed by a
  • receiver at position H at tH/c. The absorber
    is receding
  • at velocity
    and detects
  • the photon at the Doppler shifted frequency
  • The fractional change in frequency is the same
    as that
  • in Eq. (2).

16
  • Conclusions Implications
  • For a spherical object of mass M and charge Q,
    the
  • metric outside it in the presence of a test
    particle of
  • mass m and charge q is given by
  • The Special Relativistic Electromagnetism
    based on
  • the flat metric is an approximate theory in
    the presence
  • of nonuniform electric fields.
  • The exact theory is a General Relativistic
    (Geometric)
  • multi-metric theory based on the above metric.

17
  • is NOT the Gravitational Field
    (because of the
  • electrical contribution to ds2 its just
    the metric
  • tensor).
  • The present Quantum Gravity is NOT Quantum
  • Gravity. It is Quantum Spacetime Geometry.
  • Objects that can be called Black Holes for
    Electrons
  • or other charged objects can be built in the
    laboratory.

18
  • The rate of development of science is not the
    rate at which you make observations alone but,
    much more important, the rate at which you create
    new things to test.
