Gravity
Aristotle during the Greek days was considered a master; he proclaimed “heavier objects will fall faster”.
Galileo later was to say an assumption, accepted as valid today, “all objects accelerate at the same rate regardless of what they weigh”.
Sir Isaac Newton expanded upon this notion, and developed his theory of gravitation and the three laws of motion.
Albert Einstein had an ingenious mind; he stated “gravity is a distortion in the geometry of space and time”.
Lloyd Zirbes after years of tests contends, “all objects do not accelerate at the same rate my friends”.
