Is space-time a plane?

Spacetime is not flat. It can’t be: Einstein’s general theory of relativity says that matter and energy curve spacetime, and there are enough matter and energy lying around to provide for curvature.

How do we know space-time exists?

But despite all the things that spacetime enables us to predict and know, it isn’t real in the same way that an atom is real. There’s nothing you can do to “detect” spacetime directly; you can only detect the individual quanta of matter and energy that exist within your spacetime.

Is time the fourth dimension of space?

In the future, the scientists plan to investigate the possibility that quantum space has three dimensions of space, as Sorli explained. “The idea of time being the fourth dimension of space did not bring much progress in physics and is in contradiction with the formalism of special relativity,” he said.

What is the theory of space-time?

According to the best of current physical theories, space-time explains the unusual relativistic effects that arise from traveling near the speed of light as well as the motion of massive objects in the universe. Who discovered space-time?

How do the three dimensions of space work?

This is precisely how the three dimensions of space work in our Universe: in flat space, the shortest distance between any two points is a straight line. This is true regardless of how you rotate, orient, or otherwise position those two points. But our Universe isn’t made up merely of three space dimensions, but of four spacetime dimensions.

Is the mathematical model of spacetime accurate?

Other scientists have pointed out that the mathematical model of spacetime does not correspond to physical reality, and propose that a timeless “state space” provides a more accurate framework. The scientists also investigated the falsifiability of the two notions of time.
