The light-gas gun is an apparatus for physics experiments. It is a highly specialized gun designed to generate extremely high velocities. It is usually used to study high-speed impact phenomena (hypervelocity research), such as the formation of impact craters by meteorites or the erosion of materials by micrometeoroids. Some basic material research relies on projectile impact to create high pressure; such systems are capable of forcing liquid hydrogen into a metallic state.
Hello, I'm Sofia and new here! I'm working on a project in which I'm trying to show that dark matter exists. It's about an elliptical galaxy with a rotating gas disk.
What I'm doing is comparing the theoretical calculation of the rotation curve with the actual measured rotation curve. It...
