Over 350 years ago, Isaac Newton saw an apple fall from a tree and he began to wonder why it fell straight down rather than floating upwards or sideways. Being a person of very great brain he surmised that there must be a force pulling the apple to the ground and from there he devised a number of theories and experiments that explained what gravity does, but it wasn’t until 1915 when another scientist Albert Einstein published his works that we began to understand how it does. Or, at least, those people who have clever brains understand it.Error: Contact form not found.
