Dr. Mike McCulloch, Lecturer in Geomatics, had created a model for inertia called: Modified inertia by a Hubble-scale Casimir effect (MiHsC) or quantized inertia. Nextbigfuture covered it a few months ...

The equivalence principle is one of the more fascinating ideas in modern science. It asserts that gravitational mass and inertial mass are identical. Einstein put it like this: the gravitational force ...

First, this all came after the latest MythBuster's episode where they tried to have a surf board fly off a crashing car and into another car. I don't have the exact quote, so I am just going to make ...

One of the pillars of Einstein's Relativity is the principle of equivalence: the equivalence of inertial mass and gravitational mass. According to Einstein, the force of gravity keeping your feet on ...

Physicists report that electrons in semiconductor crystals have a negative inertial mass when strongly accelerated in an electric field. Physicists of the Max Born Institute in Berlin report in the ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...

Antimatter is anti- a lot of things, but it’s not supposed to be antigravity. An antimatter particle does have the opposite electric charge of its ordinary matter counterpart. But the mass of both ...

What is this thing called mass? Pondering this apparently simple question, two scientists have come up with a radical theory that could explain the nature of inertia, abolish gravity and, just ...
