The fundamental nature of matter
Everything in the Universe in motion
Every solid thing that you see is in fact in a state of flux at the molecular level. To give you more insight, here’s the transcript from The invisible motion of still objects:
“Many of the inanimate objects around you probably seem perfectly still. But look deep into the atomic structure of any of them, and you’ll see a world in constant flux — with stretching, contracting, springing, jittering, drifting atoms everywhere.
Ran Tivony describes how and why molecular movement occurs and investigates if it might ever stop.”

Mass and Energy
Einstein’s explanation of E=mc2 (transcript below)

“It follows from the Special Theory of Relativity that mass and energy are both but different manifestations of the same thing – a somewhat unfamiliar conception for the average mind. Furthermore, the equation E is equal to mc², in which energy is put equal to mass, multiplied with the [by the] square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa. The mass and energy were in fact equivalent, according to the formula mentioned before [E = mc²]. This was demonstrated by Cockcroft and Walton in 1932, experimentally.”
E = mc2
The equation states that mass and energy are the same thing and tells you how much energy is contained inside a certain amount of mass.
Everything you see around you that has mass and looks solid is in reality only huge concentrations of energy.
