About This Design

Supermassive Black Hole Coaster

Supermassive Black Hole Coaster

The darkness among the stars is a supermassive black hole at the core of a galaxy in a remote part of the universe, as imaged by the Hubble Space Telescope. The event horizon makes the light from background stars stretch and smear due to the massive gravity equal to 17 billion suns. Black holes are though to exist at the centre of every galaxy.

Beautiful horse drawing on this coaster makes it a great conversation piece. Artist is very talented! The printing Zazzle did is nice and crisp, but not as black as I would have liked and the edges had some execess on them But some sandpaper fixed the issue
