You probably see me share a lot of science projects, but I also work on my own.

The current game: Agent Higgs 2!

It's a puzzle game where the pieces are the particles of the Standard Model.

Yes, *all* the particles. Yes, it was a questionable scope. Yes, it's still under development. (1/?)
Title screen of a cartoony style game. Title Agent Higgs 2, subtitle: Escape from the Standard Model.  There are three buttons shaped like folders that say Play, Editor, and About.  There is a red H with groucho Marx glasses in the middle of the screen, partially hiding behind a wooden crate.  Around them are a variety of crates as well as particle tiles.  There is a blue box with a p and a plus sign on it, representing  a proton.  Similarly there is an electron, muon, tau, and neutron block. Level in a grid based puzzle game. There are a variety of tiles, with Higgs trapped behind many wooden boxes in the corner.  There are four electrons grouped together, and four positron tiles in a vertical line nearby.  A small mysterious figure says "Don't think of it as particles dying. Think of it as particles changing. Changing into... being dead. You know what, let's move on." Tile based level of a game. Again, Higgs is in the lower corner, this time blocked by many black tiles representing holes in the level.  There are four protons and four neutrons grouped in the upper left of the level.  This time the mysterious figure says "A little danger is nothing you can't handle... right?"

A box of gas (blue) + dark matter (green), now with a smoother distribution at the start.

I love this simulation of the early universe, part of our new CMB project.

This is early on - (~300,000 years after the Big Bang). The universe is so hot, plasma is everywhere. Photons can't travel far, bouncing off electric charges.

Some more 'gas' particles - this time two clumps in orbit. Pretty dangerous tides, if you ask me.

*building a time machine to place my hand firmly on these photons and electric charges as I say "no" to prevent everything after from happening before it's too late*

The clues were all there...

It's this light that forms the Cosmic Microwave Background that we see today.

This ancient light tells a pretty cool story about its journey. To learn a bit more, the first part of our project is available here: testtubegames.com/cmbjourney.h...

And here we are at about 380,000 years after the Big Bang.

The universe has cooled enough that neutral atoms are common, and loose charges are rarer. Photons can finally travel in mostly straight lines.

Some of them traveled in mostly straight lines for billions and billions of years, in fact!

Video description: Again red positive charges and blue negative charges bounce around the screen, scattering the white wiggly photons that are moving through. There are some dull grey atoms now, though, too, which occasionally form from the charges.

As the universe expands, it cools. Some neutral atoms (grey) are able to form briefly -- and these don't scatter the photons as much. Still the photons get bounced around.

(This is at about ~360,000 years after the Big Bang.)

Video description: A few dozen red positive charges and blue clouds of negative charge are bouncing around the screen. There are white wiggles representing photons moving around as well, some of which have paths traced behind them. The photons bounce frequently.

Oops, the gas simulation made a Saturn, I guess?

Related physics puzzle - can you figure out this SPOOKY force law?

Bonus point: If this force law were to dress up for Halloween, what costume would it wear?

Tis a season.

Why does the ghost behave the way the ghost does? An eternal, and in this case, very specific, question.
