The particles that make up light, photons, may live for at least 1 quintillion (1 billion multiplied by 1 billion) years, new research suggests.
If photons can die, they could give off particles that travel faster than light.
Many particles in nature decay over time. For instance, radioactive atoms are unstable, eventually breaking down into smaller particles and giving off energy as they do so. [Read more] ...
