Mass-energy equivalence and the gravitational redshift: Does energy always have mass?
Germano D'Abramo
One of the most widespread interpretations of the mass-energy equivalence establishes that not only can mass be transformed into energy (e.g., through nuclear fission, fusion, or a…
Non-cosmological, Non-Doppler Relativistic Frequency Shift over Astronomical Distances
Germano D'Abramo
We investigate in detail an apparently unnoticed consequence of special relativity. It consists in time dilation/contraction and frequency shift for emitted light affecting acceler…
Mass-energy connection without special relativity
Germano D'Abramo
In 1905, Einstein carried out his first derivation of the mass-energy equivalence by studying in different reference frames the energy balance of a body emitting electromagnetic ra…
A note on Purcell's basic explanation of magnetic forces
Germano D'Abramo
In the 1960s, E.M. Purcell presented a basic explanation of the magnetic force experienced by a test charge moving parallel to a stationary current-carrying wire. According to Purc…
On apparent faster-than-light behavior of moving electric fields
Germano D'Abramo
For every observer, however distant, the electric field of a uniformly moving charge is always directed away from, or points towards, the instantaneous present position of the char…
Astronomical distances and velocities and special relativity
Germano D'Abramo
We show that some primary special relativity effects, which are believed to be hardly detectable in everyday life, such as time dilation, relativistic Doppler effect, and length co…
