A new experiment deepens the physics mystery over "big G"
Fundamental forces and constants govern the universe, with electromagnetism well-measured, while gravitation remains poorly understood despite its historical significance.
Ask Ethan: Why is there no such thing as antigravity?
Gravity dominates cosmic scales because mass-energy is always positive, so gravitational attraction never cancels and accumulates across large distances.

Can you explain the strong nuclear force without colors?
The strong nuclear force is required to hold the core of every species of atom together, preventing the repulsive force between protons from destroying the nucleus instantly.
