I love space. even though I spend far more time looking at a gray office ceiling than at the sky or the stars.

However physically simulating the cosmos is computationally too heavy. To address this, I translated the mathematics of the universe into computational math by using geometry to replace certain parameters.

For in depth details, please refer to the docs. for a quick overview you can check out the two code examples provided.

Thank you.
