3.1 Matter and Energy Kinetic Theory of Matter: – All matter is made of atoms – Atoms always in motion; hotter = faster, faster = hotter – Heavier particles. Main Points All matter is made up of invisible particles Particles have spaces between them Particles are moving all the time Part...

He believed matter was made up of tiny individual particles called atomos, from which the English word atom is derived. 他认为物质由微小的不可分割的粒子组成,将之称为atomos,英语单词原子atom由此衍化而来。 Democritus believed that atoms could not be created, destroyed, or further divided. ...

Rare, extreme examples of clusters caught in the act of colliding seem to be challenging the accepted view that dark matter is made up of heavy particles. [13] Dark matter may not be made of tiny particles as most scientists believe, but instead may consist of large chunks of strange ...
In a new study, researchers outlined their idea that dark matter is made of particles they called "Macros." The scientists theorized that if these particles were as dense as atomic nuclei, they could not be smaller than 0.12 pounds (55 grams). If they were, existingparticle detectorswould ha...
