People ask what kind of chalk pencil do I use. Honestly, I use many different kinds. I am currently using Dritz Chalk pencil. It works well. I have no complaints.

I’m just kind of burnt out on digital art for now...so instead have this chalk pencil drawing of Stella encountering a traveling black hole.
It is a little-known effect, but if the magnetic field strengths in a black hole’s jets are asymmetric, the black hole will experience a net thrust. A large asymmetry in jet power is possible, and so in principle, one could get even a supermassive black hole moving.
The effect is discussed here:

Fortunately for us, it does not appear this process is really common in nature. Which is probably a good thing.
Holy shit. Why did nobody tell me sepia's a freaking cheat code?
