Summary:
Physicists have discovered that when beams of light interact at the quantum level,
they can generate ghost-like particles that briefly emerge from nothing and affect real matter.
This rare phenomenon, known as light-on-light scattering, challenges the classical idea
that light waves pass through each other untouched.
