## What is Relativistic?

Experience the world at the speed of light. Relativistic lets you set the speed of light to walking pace and then walk around your neighborhood and see the effects of relativity in real time. Place observers on a map and watch their time slow down and speed up relative to you as you move. Place a black hole at the end of your road and watch outside observers glow blue as you walk towards its singularity. Relativistic provides an intuitive way to learn about and teach the details of Einstein's theory of relativity.

## Key features

- Adjustable speed of light
- Real-time relativity effects
- Observer placement and time dilation
- Black hole simulation
- Gravitational blueshift visualization
- Intuitive learning tool
