- Hello and welcome to a black hole coding challenge.

Adverbs of degree

I'm actually now recording this many days

after the actual livestreamed coding challenge.

In a little bit, I will change my clothes and

travel into the past through the black hole.

In truth, it's less simulation than visualization.

the first ever image of a black hole was published.

This image was put together by a team of scientists

It was compiled from data from many telescopes

I quickly realized I'm many, many steps away from doing that

somewhere where I could at least begin to

Here are the resources that I used to learn about this.

the how to understand the image of a black hole.

If you watch this video, the explanation is superb.

In particular, there's a short animation in the video

That's my starting point where I was interested in.

I also learned quite a bit from Chris Orbin

They have a lot of videos about physics and science

taught through the lens of coding and visualization.

code example could be tweaked a little bit

Finally, there's a wonderful paper from 1978.

Thank you to Veritasium also for this reference

This paper has diagrams and the mathematics

behind the photon trajectories around a black hole.

what you would want to do to visualize a black hole.

Of course, I'm not the first one to try this.

Many people have made beautiful visualizations

but there's a lot of artistic license there.

I also want to point out to you Ricardo Antonelli

Geodesic Raytracing in Curved Space Time.

In the article he goes through step-by-step

a bunch of different computer graphic tricks and techniques

along with the sort of physics of black holes themselves

to create a 3D visual of what a black hole might look like.

you know I am not a physicist, I'm not a scientist.

as a sort of reference point for when I start coding.

The black hole that I want to visualize is in the galaxy M87.

It was just called M87 star, the star for black hole,

I'm not sure if I'm pronouncing that correctly,

fathomless creation, something like that.

This is what's known as a super massive black hole.
