Ghosts exist: A Journey Through Light and Time
Welcome to a captivating exploration brought to you by the team at We invite you on a journey through light and time, where we will uncover the existence of a unique type of ghost. These are not ethereal beings of folklore but rather cosmic entities that dwell in the vast expanse of our universe. Brace yourself for a celestial expedition that challenges conventional perspectives.

In the cosmic playground that we inhabit, there are ghosts - not of human or animal kind, but of a cosmic nature, belonging to something far grander. As we know, light possesses an extraordinary speed, essentially the fastest phenomenon in the universe. Yet, even at its breathtaking pace, light requires time to traverse the immense expanses of the cosmos. To comprehend these vast distances, we employ unique units of measurement: light seconds, light minutes, and light years.

Consider our Sun, positioned 8 light minutes from our Earth. This distance implies that our perception of the Sun is always as it appeared eight minutes prior. To observe the Sun in its current state, one would need to undertake the journey to it.

Beyond our Sun, our nearest stellar neighbour is Proxima Centauri, situated approximately 4 light-years from Earth. Consequently, we perceive Proxima Centauri as it existed four years in the past, when the light we now perceive was initially emitted. The remaining celestial bodies in our night sky reside at even greater distances, ranging from hundreds to thousands of light years away. When we gaze upon the night sky, we're effectively peering into the historical tapestry of our universe, witnessing phenomena from epochs we can scarcely fathom.

Interestingly, some of the light that graces our eyes originates from stars that have long since perished. The journey of this light has been so extensive that by the time it reaches us, the star responsible for its creation has been extinct for an inconceivable duration. Thus, when we survey the night sky, we are in essence observing the skeletal remains of innumerable star systems and reading the cosmic epitaphs.

While human and animal spirits may be the stuff of legends, the night sky teems with its own spectral inhabitants. Through this exploration, the team at aims to enrich your understanding of these cosmic ghosts and their intriguing tales of light and time.
