Evidence indicates that the Cosmic Microwave Background Radiation is the electromagnetic radiation left over from the formation of the universe.
True
The directionality in nature; i.e., the tendency of ordered systems to become disordered, is ultimately the result of the motion of atoms and molecules.
True
The fundamental basis for the idea of astrology was that heavenly bodies controlled the occurrence of the seasons and therefore, they could control human affairs.
True

John is an inventor and he recently claimed that he had developed a perpetual motion device. This is a device that, once set in motion, will remain in motion because all of internal energy supply is converted into useful work. John's claim:
is impossible due to the Second Law of Thermodynamics (entropy/disorder increases with time; i.e., waste heat is always produced and results in a loss of energy available to do work)

there is no experimental evidence to support it there are many versions of astrology and they are inconsistent with one another and therefore subjective the claims of astrology contradict well-established principles of physics and biology
Bohr showed that:
when electrons shift from one electron shell to another, they emit a specific amount of energy - quanta of energy electrons move from one shell to another, without crossing the space in-between, in a process he called a quantum jump
