About 380,000 years after the Big Bang, the black body radiation that filled the universe was at a temperature of about 3,000 degrees K. Today, these same photons are at a black body temperature...

The interferometer mirrors used to detect gravitational waves are usually described as moving when a gravitational wave passes. This is an easy to understand explanation, but is it correct? Moving...

I think that physicists are too quick to claim that “the laws of physics break down” when they cannot explain something. For example, any discussion that involves the concept of a singularity is...

Some physicists believe that gravity is not a real force like the electromagnetic or the strong force because an inertial frame of reference eliminates the effects of gravity. However, it can be...

John Archibald Wheeler said: “Empty space is not empty.” However, there are many different models of the energy content of the vacuum. One extreme position is that the only energy density present...

The electromagnetic force is modeled as being transferred by virtual photons. These are messenger particles which must be able to create a force at a distance of either attraction or repulsion....

A muon has about 207 times more energy than an electron. It seems that there must be some difference between these two particles that produces this difference. The standard model says that...

Neutrino flavor oscillations are often described as involving a mass/energy change. The flavor oscillation is also described as the result of a superposition of mass eigenstates which propagate at...

The existence of gravitons is currently being debated. The standard model is a quantum field theory. Forces are transferred by the exchange of gauge bosons such as virtual photons and gluons. In...

It is not sufficient to merely explain that muons are more massive than electrons because they interact more strongly with the Higgs field. For example, an electron with energy of 0.511 MeV must...
