Newton proposed the existence of ether as a medium for transmitting forces between particles In his Hypothesis of Light

In his Hypothesis of Light, Newton proposed the existence of ether as a medium for transmitting forces between particles. This idea emerged during a period when the boundaries between alchemy and science were not well defined. Newton's engagement with Henry More, a Cambridge Platonist philosopher, played a crucial role in shaping his thoughts. More's influence led Newton to explore alchemical concepts, which were prevalent at the time. As a result, Newton transitioned from the notion of ether to the idea of occult forces, drawing on Hermetic principles of attraction and repulsion among particles. This shift marked a significant evolution in Newton's understanding of light and its properties, as he sought to explain the behavior of light through these newly conceived forces rather than through a physical medium like ether. The impact of Newton's Hypothesis of Light was profound, as it laid the groundwork for future explorations in optics and the nature of light. His ideas contributed to the development of theories that would eventually lead to the formulation of the wave and particle theories of light. Newton's work prompted further investigation into the nature of light, influencing scientists and philosophers alike. The discussions surrounding his hypothesis also highlighted the interplay between scientific inquiry and philosophical thought during this era. As a result, Newton's exploration of light not only advanced the field of optics but also encouraged a broader dialogue about the fundamental forces that govern the natural world.
