Sir Isaac Newton

Quest. 31.  Have not the small Particles of Bodies certain Powers, Virtues, or Forces, by which they act at a distance, not only upon the Rays of Light for reflecting, refracting and inflecting them, but also upon one another for producing a great Part of the Phenomena of Nature?  For it’s well known, that Bodies act upon one another by the Attractions of Gravity, Magnetism, and Electricity; and these Instances show the Tenor and Course of Nature, and make it not improbable that there be more attractive Powers than these… .  For we must learn from the Phenomena of Nature what Bodies attract one another, and what are the Laws and Properties of the Attraction,  before we enquire the Cause by which the attraction is perform’d.  The  Attractions of Gravity, Magnetism and Electricity, reach to very sensible distances, and so have been observed by vulgar eyes, and there may be others which reach to so small distances as hitherto escape Observation, and perhaps electrical Attraction may reach to such small distances, even without being excited by friction.  

Sir Isaac Newton developed the three basic laws of motion and the theory of universal gravity, in the 17th century, stating such in his book, Opticks, which together laid the foundation for our current understanding of physics and the Universe.

Newton had suggested that there is motion in all particles, particularly the forces of gravity and heat energy, where it is said that these things are simply molecular movement.
