Velocity Raptor

Velocity Raptor must travel near the speed of light to save the world!

Have you ever wondered what happens near the speed of light? What this "relativity" is that everyone is talking about? Well, leave your textbooks at home, because today you'll experience the real thing!

This is a place where objects shrink before your eyes, colors shift across the spectrum, and bullets travel in strange paths.

Confused yet? Good. Then you're well on your way...

The Science

This game is based on an accurate simulation of the world at high velocities. Its basis? The equations of Special Relativity, namely the Lorentz Equations. Space is changed correctly. Time is changed correctly. And in certain cases, color is changed correctly, too. In later levels, the simulation even shows what you would "see" when traveling near the speed of light, which is oddly different than what you might expect.

For Teachers

Are you a teacher looking for resources? Great! Unfortunately, we haven't created any teacher tools for this game yet, but if you do end up using the game as part of a classroom activity, I'd love to hear about it!
