Energy can be transferred or transmitted through a substance through conduction, convection or radiation.

Particle physics is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them. It is also called "high energy physics", because many ...

Einstein’s cosmological constant (lambda) implied the existence of a repulsive form of gravity. Quantum physics holds that even the emptiest vacuum is teeming with energy in the form of ...

Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and ...

Energy is also transferred by convection, through the currents formed when the hot air above it rises. Radiators cool down the engines of petrol or diesel vehicles like cars.
