The case for and against a 5th fundamental force of nature

Current physics theories cannot explain fundamental cosmic mysteries like matter-antimatter asymmetry, dark matter, dark energy, and cosmic inflation, suggesting undiscovered forces or phenomena remain.

A 100-year-old theory might explain what's wrong with quantum mechanics

Pilot wave theory, developed by Louis de Broglie a century ago, potentially resolves quantum mechanics' paradoxes by describing particles guided by attendant waves rather than existing in superposition.

What are the most energy-efficient reactions in physics?

In terms of making things happen, energy is an indispensable consideration. Systems spontaneously tend towards the lowest-energy state. When a system reaches equilibrium, no further energy can be extracted. That maximum entropy, lowest energy state is the inevitable end-state of the Universe. But until that moment arrives, reactions of all kinds will occur, continuing to liberate energy. In our bodies, chemical bonds break and reform: releasing energy.
