In fact, understanding this fundamental constant is a key to much of what we know about the universe, especially in respect to both General Relativity and Quantum Mechanics. This speed has been determined through many rigorous tests and physical proofs. One of the fundamental properties of the universe that we know quite well is that light travels at a finite speed: approximately 300,000,000 m/s (roughly 671,000,000 mph). What many don’t realize is that when we look out deep into the universe, we are not only looking across vast distances, but we are peering back into time. Stellar ghosts is an apt way of describing many of the massive stars we see scattered throughout the universe. Yet, as we know from our privileged vantage point, this star is about to go supernova and birth one of the most spectacular nebulae that we observe today. To an observer before this date, this star appeared eternal, as all the other stars did. This star has died, however at this moment in time we wouldn’t have known that. The brightness fades and eventually there lay a pinpoint of light a star that we don’t see today. As the calendar approaches July 5, 1054, the gaseous cloud brightens and settles onto a single point in the sky that is as bright as the full moon and is visible during the day. As the clock winds backwards, the colors of the nebula begin to change, and you notice that they are shrinking to a single point. You reach out and with the flick of your wrist, begin rewinding time and watch this beautiful nebulae begin to shrink. Its beautiful colors extend outward into the dark void a celestial tomb containing a violent event that occurred a millennia ago.

We begin this journey by observing the Crab Nebula. What happens to the largest of our stars, and how that influences the very makeup of the universe we reside in.

That is what we will be discussing today. Our sky is blanketed in a sea of stellar ghosts all potential phantoms that have been dead for millions of years and yet we don’t know it yet. The Crab Nebula at its core is a long dead star… Image credit: NASA, ESA, J.
