Interactive relativistic Blackhole simulation

In my black hole simulation, I have made it so that when you :

Press up/down arrow: the screen will rotate up/down

Press w/s: Solar mass of our black hole will increase by a factor of 2

Press z/x: you will zoom in/out

Press I: A dialog box will appear in which you can automatically select the desired solar mass rather than using w/s to tune it up/down.

Along with these, I have also included some easter eggs, like if you type TON618, which is the largest black hole ever found, then you will see a bit exaggerated simulation of it. Similarly, you can also type M87 (It's the first ever black hole that we have captured using telescopes; it's known for its polar jets, which span thousands of light years), and you will see a simulation which is extremely close to real-life results. In the M87 simulation, I have an optical filter mode which can be closed by pressing "j" on your keyboard. When the optical filter is on, you will see how it will be to observe M87 with low-frequency detecting instruments, and when it's toggled off, you will be able to see what it will be like to see it with naked eyes (means in the visible spectrum) {spoiler: M87 polar jets are a bit over-exaggerated to be visually pleasing}

If you try to move just above a simulated black hole, you get caught in its extreme magnetic field (I made this because my simulation was crashing when we moved just above or below a black hole XD) Also, if you left-click on the screen, a dummy astronaut will fall into the black hole and get spaghettified, and we can also see he is getting slower and skower due to time dilation effect
