According to the general theory of relativity, kinetic energy contributes to gravitational mass. Surprisingly, the observational evidence for this prediction does not seem to be discussed in the literature. I reanalyze existing experimental data to test the equivalence principle for the kinetic energy of atomic electrons, and show that fairly strong limits on possible violations can be obtained. I discuss the relationship of this result to the occasional claim that “light falls with twice the… Expand
Gravitational mass of composite systems
The equivalence principle in combination with the special relativistic equivalence between mass and energy, E = mc(2), is one of the cornerstones of general relativity. However, for composite systemsExpand
True dynamical tests of the weak equivalence principle for matter and anti-matter
After a brief review of the evidence for the validity of the Weak Equivalence principle for anti-matter, I show that, contrary to general belief, the near equality of the Shapiro delay for photons,Expand
Breakdown of the equivalence between gravitational mass and energy for a composite quantum body
The simplest quantum composite body, a hydrogen atom, is considered in the presence of a weak external gravitational field. We define an operator for the passive gravitational mass of the atom in theExpand
Breakdown of the equivalence between active gravitational mass and energy for a quantum body
We determine active gravitational mass operator of the simplest composite quantum body - a hydrogen atom - within the semiclassical approach to the Einstein equation for a gravitational field. WeExpand
Inequivalence between gravitational mass and energy due to quantum effects at microscopic and macroscopic levels
We review recent theoretical results, demonstrating breakdown of the equivalence between active and passive gravitational masses and energy due to quantum effects in General Relativity. InExpand

Within the thermodynamic model of gravity the dark energy is identified with the energy of collective gravitational interactions of all particles in the universe, which is missing in the standardExpand

We review recent theoretical results, obtained for the equivalence between gravitational mass and energy of a composite quantum body as well as for its breakdown at macroscopic and microscopicExpand
Renewed relevance of new tests of the equivalence principle involving intrinsic properties of particles and antiparticles
The equivalence of the Shapiro delay for photons and (anti)neutrinos is the currently accepted lone test of the equivalence principle concerning intrinsic properties and quantum numbers ofExpand
A significant question in experimental gravity is the nature of free fall of antiparticles under gravity and elaborate preparations are underway to directly test this with cold antihydrogen. Earlier,Expand
Comment on “Does the Equivalence between Gravitational Mass and Energy Survive for a Composite Quantum Body?”
Lebed has given an argument that when a hydrogen atom is transported slowly to a different gravitational potential, it has a certain probability of emitting a photon. He proposes a space-basedExpand


The equivalence principle
Abstract The experimental basis of the equivalence principle is reviewed, and the implications for the gravitational interactions of elementary particles are studied within a special relativisticExpand
Principle of equivalence and the deflection of light by the sun
We review the usual principle‐of‐equivalence calculation for the deflection of light by the sun, which fails to give the general relativistic answer. We show that the discrepancy arises because, byExpand
The Equivalence Principle in the Non-baryonic Regime
We consider the empirical validity of the equivalence principle for non-baryonic matter. Working in the context of the T Hǫ� formalism, we evaluate the constraints experiments place on parametersExpand
Gravitational deflection of fast particles and of light
The gravitational deflection of relativistic particles and of light is discussed from a simple point of view, in terms of velocity‐dependent forces in flat space. This picture is shown to beExpand

Local and Global Light Bending in Einstein's and Other Gravitational Theories
To remedy a certain confusion in the literature, we stress the distinction between local and global light bending. Local bending is a purely kinematic effect between mutually accelerating referenceExpand
