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 ...

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 ...

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 ...

About 10 years ago, a little-known aerospace engineer called Roger Shawyer made an extraordinary claim. Take a truncated cone, he said, bounce microwaves back and forth inside it and the result will ...
