Start with a star and play over 50 levels to watch it become a black hole. Hurl your star across spacetime to hit your target. Navigate fields of cosmic objects and hazards—like neutron stars and quasars—avoiding some and slingshotting around others in your quest to become more massive. Reach the end and your star collapses….to become a black hole. Then watch the two-hour NOVA program, “Black Hole Apocalypse,” hosted by astrophysicist Janna Levin.

Really need a zoom out option...

I use an iPad Pro, and because your star is so close to the edge of the screen it is impossible to get to higher starting speeds on many levels without slipping my finger off the screen and automatically launching the star. A simple zoom-out option would fix this!

Pretty decent

I get why people might think it's impossible, but an easy game is no fun. Keep at it. I agree, as sequel would be fun. Gave it 4 stars only because it crashed several times.

My kids loved playing with the different scenarios and have been much more interested in cosmology. It's a great demonstration of things that happen on a scale we don't really get to see. Thanks, Nova!
