Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively explain the many intricate ...
Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet Earth rolls around the sun ...
