Photons

The modest photon, ah. Everyone is aware of photons. Light as we know it is made up of photons, tiny units of electromagnetic energy that enable light to act as both a particle and a wave. Of course, photons are more than just the light from your phone's screen reaching your eyes to let you view this. A photon is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation like light and radio waves, and is the force carrier for the electromagnetic force.

Due to their lack of mass, photons always travel at the speed of light in a vacuum, which is 299792458 m/s (or 186,282 mi/s). The photon is a member of the boson family. They are also the wifi that connects you to the internet, in addition to radio waves, microwaves, x-rays, gamma rays, and other technologies.

Photons are responsible for enabling what we perceive. In other words, those photons went that far to get here when we look across the cosmos and see a star that exploded a billion years ago, making them major workhorses of the particle world.
