The Plumb Pudding Model

Physicists have been building particle colliders as a way to learn about the fundamental workings of the universe. At this time, physicists had started to become convinced that matter is made up of atoms but they didn't know much about the atoms themselves. Our best guess for how atoms were kind of constructed was something called the Plumb Pudding Model. According to this theory, atoms were basically just a big blob of positively charged matter with a number of negatively charged electrons embedded at different places in it.
