Advanced Astrophysics (And Arts & Crafts), Friday, 3rd period - 5/27
Today, the classroom set up was altered enough to allow room for a number of pottery wheels for each student to work at should they not wish to take notes on the lecture. But what were the odds of that happening?
Reed had a lab coat on as his only concession to the no doubt messy work of pottery making. Because science was way more important than pottery, darn it. "Hello, everyone!" he said cheerfully, passing out a worksheet of a simple, easy to understand explanation of how to make a pot with those wheels. It was probably for the best that Reed did it this way because the Ghost jokes would be rampant otherwise. Rampant!
"While you work on your pots or whatever else you feel like making." A beat. "Please, nothing offensive."
Look, Johnny trained him and everything! Awww, best family ever.
"While you work, I'll be delivering the lecture on our next subject of interest: black holes." No snickering! "A black hole is an object in space that is like--a sort of cosmic sink hole that sucks in all matter that comes too close to the event horizon. The point of no return, if you will."
And not a horrible movie.
Above the heads of the students heads, an image of a black hole distorting the view of the galaxy just behind it appeared. Because it wasn't a lecture without some images to help people understand them.
"The most common explanation for the formation of these objects is the collapse of a star," Reed continued. "Stars function in a state where the gravity pushing in on them is just met my the output of the stellar nucleosynthesis occurring within. This can happen when the star simply runs out of fuel over the full course of its 'lifetime'. Or, in the case of binary star systems where there are--obviously--two stars orbiting each other, one feeds off the other. This can be enough to destabilize one or both of the to create a black hole." A beat. "Or supernova, depending on the particular circumstances of that system."
He cleared his throat before continuing on. "At the very center of a black hole is what is called a gravitational singularity. It's a spot where the space-time curvation is infinite. Outside of that is the event horizon, which I already mentioned before. Any object that crosses that is subject to what is called spaghettification."
Oh god, don't be so cheerful about that, Reed.
"I which it is pulled apart, spread over the event horizon before being compressed and added to the mass of the black hole," he added. "Then there is the ergosphere, which is a spheroid shaped region in which objects are pulled around the event horizon. Beyond that is the photon sphere where matter can be pulled in toward the event horizon or, alternately, pushed away and back into the space surrounding it."
"As these black holes continue to take in mass, they can become larger and turn into what are called supermassive black holes," Reed added, pushing a few buttons for another visual demonstration. "This can also occur when they merge with stars or other black holes--why aren't we working today?"
A tap on the side of his computer only produced a bit of music for the class. Reed sighed, crossing his arms over his chest. "I think that concludes the lecture for today."

Or she would be, if she could just get the stupid thing centered. She understood all the mechanics of what the sheet described, why couldn't she get it to work?

So he just kind of took the clay off the wheel, broke it into three pieces, rolled those pieces into spheres, and made a snowman while he listened to Mr. Richards talk about black holes.
He was so very artistic.

It still wasn't going to stop him from trying to make one.
