⇑Definitions and quotes

Earth
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.
Energy
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.
Earth
Earth below us
drifting, falling.
Floating weightless
calling, calling home...
Peter Schilling, song Major Tom (Coming Home) (1983).

Earth
They will not cause any harm
Or any ruin in all my holy mountain,
Because the earth will certainly be filled with the knowledge of Jehovah
As the waters cover the sea.
Book of Isaiah 11:9.
