Many people are interested in Einstein's theory of relativity as I am, but its complicated mathematics keeps us out. This game provides us with an opportunity to intuitively experience the wonderful appearance of objects under general relativity.

In a world dominated by gravitation, all objects appear so symmetrical and elegant. Black holes are the most representative existence in this magnificent world.

Game features:

1. Simulate the appearance of the black hole as accurately as possible.

2. You can adjust the parameters to change the appearance of the black hole.

3. You can also add a star to observe the interaction between the black hole and the star.

4. There are multiple space background sky boxes.

5. Fly into the black hole, see the cosmic ball.
