Why Even Physicists Still Don't Understand Quantum Theory 100 Years On

A century after quantum mechanics revolutionized physics, scientists still cannot agree on how the theory fundamentally works, despite its tremendous success in explaining natural phenomena and enabling modern technologies. The theory's central puzzle remains unresolved: the way quantum systems are described mathematically differs from what scientists observe when measuring them.
This has led to competing interpretations about whether quantum states represent physical reality or are merely tools
