Top Physics Idea

There are a lot of interesting ideas in physics, especially in modern physics. Matter exists as a state of energy, while waves of probability spread throughout the universe. Existence itself may exist as only the vibrations on microscopic, trans-dimensional strings. Here are some of the most interesting of these ideas, in modern physics. Some are full-blown theories, such as relativity, but others are principles (assumptions upon which theories are built) and some are conclusions made by existing theoretical frameworks.

All, however, are really weird.
