Some propose that the presence of gravitational time dilation and the effect on red shifted photons means that gravitons can travel faster than light. Can some one elaborate and explain why...

It is generally thought (see Special Relativity, A. P. French) that the magnetism we detect form an electric field, is related to relative motion with respect to that field. Specifiically a moving...

Time stops at the event horizon so nothing can fall into a black hole in the lifetime of the Universe in GTR. Equally space vanishes to nothing so a black hole has a radius and a surface area but...

It is said of general relativity that it has been experimentally proven. But what about experiments involving black holes and the recent LIGO experiments - do they really uphold GTR?

GTR does not predict a bifurcation in the graviational wave at the chirp. Is there something wrong with GTR

The tests of GPS systems and the Hafele and Keating experiments suggest, that an Earth centred position is stationary. After all we do not alter Earth's clock we alter the satellite clock, there...

Magnetism what is it? We all know electricity we use it every day but a magnet is just something that hangs on the fridge door - or is it. What about the Bohr magneton is it just due to the...

Tachyonic fields are well accepted in QED and in string theory. Gravitons, the theoretical mediators of the gravitational force, if they existed, would by definition need to propagate faster than...

Black holes are considered to be the most powerful gravitational objects in the Universe. But the obvious question is if nothing (even light) can escape a black event horizon how can the effects...

Recently the first sighting of gravitational waves by LIGO were published with great fanfare. There has reportedly been a second sighting which does not readily appear in the literature. Can any...

Time is supposed to stop at the black hole event horizon. So the question is what happens inside the black hole, does time for instance go back wards as some theorists believe.

Excuse me for noting that in the general theory of relativity (GTR) time stops at the event horizon of a black hole. So in theory we can never in our "proper" time watch the two black holes merging

Action and reaction are equal and opposite- but does this apply to high amperage cable when switched on. Specifically will the cable tend to move in a whiplash fashion or any other fashion.

In early experiments SLAC found 3 point like components in both the proton and neutron. Thus confirming the quark like structure of the hadrons. A vitally important question ensues: did they find...

The classical electron radius is well known and effectively represents the charge radius which is 2.82 X 10^-15 m. The "physical" radius of the free electron has yet to be determined...

Quite simply put, chlorophyll reflects both yellow and green light. If it evolved on Earth why on Earth should it reflect yellow light, after all the Sun emits yellow light. So you would expect...

A definitive answer does not appear forthcoming from the Planck data set. Wiki quotes a critical mass density of 8.62 ^10-27 kg/m3. Others quote an overall mass density of 9.9 ^10-27 kg/m3, which...

Classically GTR predicts a slowing of time approaching the event horizon and that slowing is infinite at the event horizon. This is predicted to produce an observed red shifting of the signal and...
