Things You Thought You Knew – Quantum Cat

What It Covers

Neil deGrasse Tyson explains three quantum physics concepts: death by black hole through spaghettification, Schrodinger's cat as quantum superposition, and quantum tunneling enabling thermonuclear fusion in stars at temperatures below theoretical requirements.

Key Questions Answered

• •Tidal Forces: Black holes stretch objects through differential gravity between head and feet, eventually exceeding molecular bonds and causing spaghettification—the body snaps into progressively smaller pieces (two, four, eight, sixteen) until reduced to a stream of atoms.
• •Quantum Measurement: The observer effect occurs because measuring particles requires light photons carrying energy that physically moves small particles to different states, making it impossible to observe their original position—this is measurement interference, not consciousness affecting reality.
• •Quantum Computing: Qubits differ from classical bits by existing in superposition states—not just zero or one, but any probability distribution between them (80% one/20% zero, 50/50, etc.), enabling vastly more computational versatility than binary systems.
• •Stellar Fusion: Stars fuse hydrogen at 10-15 million degrees (not the billion degrees required classically) because quantum tunneling allows protons to bypass electromagnetic repulsion barriers—their wave functions probabilistically exist within the strong nuclear force range, enabling instantaneous fusion.
