Where Does Energy Come from and Go to? ??? Time, Physically!

“Nothing can be accelerated to the speed of light c” because it will require infinite energy to do so, even for a particle, even more so for a car, why? According to the mv²/2 formula, the energy required for getting to c-speed is finite mc²/2. However,...

Ask Ethan: Are singularities physically real?

One of the most important advances in all of physics was the development of Einstein’s General Relativity: our greatest and most predictively powerful theory of gravity. Replacing the idea of a “gravitational force” that acts on objects that never physically touch one another with ...
