This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.

the measurement of gravitational forces, and the implications of these forces in understanding the universe. It concludes with a discussion of modern physics, including Einstein's theories and ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Physics has a problem—their key models ... It is therefore important to understand how gigantic gravitational forces act in the microcosm, although this is where the laws of quantum mechanics ...

While quantum mechanics governs the behavior of particles at the smallest scales, general relativity describes the force of gravity on cosmic scales. Unifying these two frameworks has been one of ...
