Particle Accelerator: You're inside a circular accelerator where magnetic fields bend charged particles in circular paths. Real accelerators like the LHC can accelerate particles to 99.9999% the speed of light!

Quantum Tunneling: In quantum mechanics, particles can pass through energy barriers that classical physics says are impossible to cross. This is how the sun fuses hydrogen!

Particle Collisions: When particles collide at high energies, they can create new particles from pure energy (E=mc²). This is how we discover new particles!
