● Big Bang Theory. Answer: the universe began from one point billions
of years ago and has been expanding ever since
● rotation. Answer: The spinning motion of a planet on its axis
● fission. Answer: The splitting of an atomic nucleus to release energy
● fusion. Answer: the process or result of joining two or more things
together to form a single entity; the process that creates energy within
the sun's core
● nutation. Answer: a small, cyclic variation of the Earth's axis of
rotation with a period of 18.6 years, caused by tidal forces; Earth
wobbling on its axis
● precession. Answer: direction of the Earth's axis of rotation changes
over a 26,000 yr period; the North Celestial Pole will not always point
towards the same starfield
● revolution. Answer: The movement of an object around another object
