7 Things Physics Still Can't Explain
Dark matter, making up 85% of the universe’s mass, is invisible and undetectable, while dark energy drives its accelerated expansion, yet remains mysterious. Gravity, the weakest force, struggles with quantum integration. Quantum entanglement shows particles interacting instantaneously. The arrow of time flows forward despite reversible laws. Consciousness’s link to brain processes is unclear, and the imbalance of matter over antimatter in the universe is unexplained.
