Was Einstein right?

Was Einstein 100% Right ? *

The confrontation between General Relativity and experimental results, notably binary pulsar data, is summarized and its significance discussed. The agreement between experiment and theory is numerically very impressive. However, some recent theoretical findings (existence of non-perturbative strong-field effects, natural cosmological attraction toward zero scalar couplings) suggest that the pr...

General relativity at 75: how right was einstein?

The status of experimental tests of general relativity is reviewed on the occasion of its 75th anniversary. Einstein's equivalence principle is well supported by experiments such as the Eötvös experiment, tests of special relativity, and the gravitational redshift experiment. Tests of general relativity have reached high precision, including the light deflection and the perihelion advance of Me...

Mass Boom versus Big Bang: Einstein Was Right

When considering possible time variations of fundamental physical constants one has to keep firm well established principles. Following this approach we keep firm the Action Principle, General Relativity (the Equivalence Principle), and Mach’s Principle. Also we introduce a new principle under the name of “TOTAL INTERACTION” and reconsider Weinberg’s relation with a new approach. Consistent wit...

Space-time Uncertainty from Higher-dimensional Determinism (or: How Heisenberg Was Right in 4d Because Einstein Was Right in 5d)

Heisenberg’s uncertainty relation is commonly regarded as defining a level of unpredictability that is fundamentally incompatible with the deterministic laws embodied in classical field theories such as Einstein’s general relativity. We here show that this is not necessarily the case. Using 5D as an example of dimensionally-extended relativity, we employ a novel metric to derive the standard qu...
