"One can give good reasons why reality cannot at all be represented by a continuous field. From the quantum phenomena it appears to follow with certainty that a finite system of energy can be completely described by a finite set of numbers (quantum numbers). This does not seem to be in accordance with a continuum theory, and must lead to find a purely algebraic theory for the description of reality. But nobody knows how to obtain the basis of such a theory." -- Albert Einstein

"The object of all science, whether natural science or psychology, is to co-ordinate our experiences and to bring them into a logical system." -- Albert Einstein
"The Meaning of Relativity", 6th edition, page 1
Empirical findings have validated quantum field theory and general relativity theory, but, as yet, physicists are not agreed upon how these two theories might be unified into a logical system. What might be wrong with general relativity theory? Does our universe expand for an infinite duration of time?
According to Edward Fredkin, infinities, infinitesimal, perfectly continuous variables, and local sources of randomness are figments of the imagination that never occur in nature. Is Fredkin correct? I have introduced 3 speculative modifications to Einstein's field equations: (1) dark-matter-compensation-constant = sqrt((60±10)/4) * 10^-5, (2) Koide cutoff, and (3) Lestone cutoff.
I say that Milgrom is the Kepler of contemporary cosmology. I say that the Gravity Probe B science team misinterpreted their own experiment. I conjecture that the Koide cutoff explains the space roar. I conjecture that the Lestone cutoff might explain the discrepancies in the measurements of the Hubble constant. What do I mean by the "Lestone cutoff"?
Consider Einstein's field equations:
R(mu,nu) + (-1/2) * g(mu,nu) * R = - κ * T(mu,nu) - Λ * g(mu,nu) -- what might be wrong? Consider the possible correction
R(mu,nu) +
(-1/2 + dark-matter-compensation-constant) * g(mu,nu) * R * (1 - (R(min) / R)^2)^(1/2) =
- κ * (T(mu,nu) / equivalence-principle-failure-factor) - Λ * g(mu,nu), where
equivalence-principle-failure-factor = (1 - (T(mu,nu)/T(max))^2)^(1/2)
-- if dark-matter-compensation-constant = 0, R(min) = 0, and T(max) = +∞ then Einstein's field equations are recovered. For the sake of argument, assume that dark-matter-compensation-constant = 0 and that R(min) = 0 but T(max) is some very large pure number -- I call the T(max) modification the "Lestone cutoff". However, my ideas on the Koide cutoff, the Lestone cutoff, and the dark-matter-compensation-constant might be empirically wrong. Perhaps, the Gravity Probe B science team is correct about the malfunctioning of the 4 ultra-precise gyroscopes. In any case, I say that the empirical evidence shows that Milgrom is the Kepler of contemporary cosmology. Is Milgrom's MOND an essential clue for those in search of a theory of quantum gravity?
According to Stacy McGaugh: Either:
(1) Most of the Mass in the Universe is Invisible (Dark Matter), or
(2) Dynamical Laws must be Modified (MOND).
The Basic Issue, The MOND Pages, Stacy McGaugh
Consider 5 conjectures:
(1) The empirical successes of MOND indicate that supersymmetry needs to be replaced by MOND-compatible supersymmetry.
(2) Gravitons and gravitinos have D-brane charges that constitute empirical evidence that D-branes and alternate universes influence gravitational accelerations.
(3) Gravitinos are MOND-chameleon particles that have variable effective mass depending upon nearby gravitational acceleration.
(4) For galactic dynamics, most of the mass-energy of dark matter particles has the form of MOND-chameleon particles that have variable effective mass depending upon nearby gravitational acceleration. The empirical successes of MOND can be explained as follows: Replace the -1/2 in the standard form of Einstein's field by a term which represents an apparent (but not real) failure of general relativity theory. The apparent failure is caused by ignoring the existence of MOND-chameleon particles. In other words, replace the -1/2 by -1/2 + MOND-chameleon-tracking-function -- how might this explain MOND? In the range of validity of MOND, assume that MOND-chameleon-tracking-function is roughly a constant = sqrt((60±10)/4) * 10^-5 . Outside the range of validity of MOND, assume that MOND-chameleon-tracking function is roughly = 0 except for an unspecified transition range. An easy scaling argument shows that this amounts to boosting the gravitational redshift in such a way that there appears to be a universal acceleration constant as postulated in MOND.
(5) It is possible to mathematically define a D-brane corresponding to any plausible MOND-chameleon-tracking function.
