Particles of light that travel through space, encapsulating history, each photon that reaches us connects our present with the past, creating a chain of connections in which we are all part.
Each photon is a messenger from the past, a time capsule traveling through space.
When we look at the stars, we are experiencing the past in real time. The colossal distance means that the light that reaches our eyes began its journey years, and even centuries, ago. Every particle of light we see is a connection to a past that no longer exists, an echo of a moment that happened long ago.
