Tiny pieces of fire rock from inside the world can fly through the air all the way from a land near the top of the world with water all round that has lots of ice and lots of fire rock to the big place where two world-wide fights began when our parents parents (parents?) were young.
Fire rock came out two times in the last few years. I look at where the pieces have landed, and learn what the pieces are like. I also look at pieces that came out in a huge escape of fire rock in the ice-fire land about three tens of hundreds of years ago, and make a kind of land-picture of where they went.
Computers can tell me where they think that the pieces will land when the fire rock comes out. I want to use what I learn to make what the computers think more true and to be able to say what might happen if there is a huge coming up of fire rock again one day.”
