Does the present moment exist?

Essentially, what we are trying to get at is quite simple: the present moment is just a concept. It does not exist in the manner in which we have accustomed ourselves to believing. The present relies for its existence on the notions of future and past.

Do past present and future coexist?

The past, present and future are all happening simultaneously because there is only one moment in time that exists, has ever existed or will ever exist. What did Einstein say about the past present and future? Albert Einstein once wrote: People like us who believe in physics know that the distinction between past, present and future is only a stubbornly persistent illusion. Time, in other words, he said, is an illusion. Many physicists since have shared this view, that true reality is timeless.

Does time exist in space?

Einstein showed that time and space are intimately linked and that the progression of time is relative, not absolute. Although there is nothing in physics that says time must flow in a certain direction, scientists generally agree that time is a very real property of the Universe. Keeping this in consideration, how could time not exist? The problem, in brief, is that time may not exist at the most fundamental level of physical reality. As Rovelli explains it, in quantum mechanics all particles of matter and energy can also be described as waves. And waves have an unusual property: An infinite number of them can exist in the same location.

Is time real or an illusion?

According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.
