Time and space are intertwined from "summary" of A Brief History of Time by Stephen W. Hawking
The idea that time and space are intertwined is a central concept in modern physics. According to this view, space and time are not separate entities but are intricately connected in a four-dimensional continuum known as spacetime. This concept was first introduced by Albert Einstein in his theory of general relativity, which revolutionized our understanding of the universe. In general relativity, gravity is not a force that acts across a distance, but rather a curvature of spacetime caused by the presence of mass and energy. This means that massive objects like stars and planets not only bend the fabric of space, but also affect the flow of time. In the presence of a strong gravitational field, time slows down relative to an observer in a weaker gravitational field. This phenomenon, known as time dilation, has been confirmed by experiments such as the observations of clo...
