1nW = 1/1,000,000,000 = NANOWATT = 10-9
1ymW = 1/1,000,000 = MICROWATT = 10-6
1mW = 1/1,000 = MILLIWATT = 10-3
1W = 1 = A WATT
1KW = 1,000 = KILOWATT = 10 3

HUBBLE'S LAW

DISTANCE AWAY RECESSION SPEED

RECESSION SPEED = (HUBBLES CONSTANT) X DISTANCE


THE BIG BANG - THEORY

ALL MATTER IN UNIVERSE EXPLODED OUT OF AN INFINITIELY SMALL
POINT

UNIVERSE CONTINUES TO EXPAND AND COOL

EVIDENCE:
