Does space and time exist?

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.

Is space/time real or a concept?

Space-time is not a real thing. Space-time is only a theoretical mathematical model used to help explain some elements of the universe. The universe does not have to do what the theory claims, the theory has no power over the universe. It is only a explanation for how the universe appears.

What exists between space and time?

is negative, the spacetime interval is spacelike, meaning that two events are separated by more space than time. Spacetime intervals are zero when. In other words, the spacetime interval between two events on the world line of something moving at the speed of light is zero. Such an interval is termed lightlike or null.

How long is 1 hour in space?

One hour on Earth is 0.0026 seconds in space.

Is time 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.

How long is 1 year in space?

**One year in space would be 365 days /1 year on earth…..

How long is 1 day in space?

Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

Can time be stopped?

The simple answer is, "Yes, it is possible to stop time. All you need to do is travel at light speed." The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein's two Relativity Theories.
