fundamental building blocks
how these interact summarizes our knowledge about subatomic composition FERMIONS particles that make up matter BOSONS particles that transmit forces FOUR FUNDAMENTAL FORCES GRAVITY ELECTROMAGNETISM WEAK NUCLEAR FORCE STRONG NUCLEAR FORCE STANDARD MODEL GRAVITY ELECTROMAGNETISM WEAK NUCLEAR FORCE STRONG NUCLEAR FORCE } I wish I had a quantum theory... ENTER STRING THEORY { to provide a complete, unified, and consistent description of the fundamental structure of our universe THE THEORY OF EVERYTHING D F# A G# Bb Like the strings of a guitar...
