What is the space/time made of?

The biggest lesson from Einstein’s general theory of relativity is that space itself isn’t a flat, unchanging, absolute entity. Rather it’s woven together, along with time, into a single fabric: spacetime. This fabric is continuous, smooth, and gets curved and deformed by the presence of matter and energy.

Is space time 1d?

Space time is thus four dimensional. Mathematical events have zero duration and represent a single point in spacetime.

What is space time equation?

The equations that describe specifically how spacetime bends in the presence of mass are known as the Einstein field equations, and are the mathematical basis of Einstein’s theory of general relativity.

What is a black hole in space?

A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.

What is the difference between our time and space time?

Difference between “space and time” and “space-time” is basically of symmetry. When we deal with space and time as different objects then transformations which mix time coordinates with spatial ones are not allowed. On the other hand if we consider space-time as one thing then such transformations too…

What are the dimensions of time and space?

In general physics , time is considered to be as the 4th dimension. The 3 dimensional space and time together are taken to be as the 4 dimensions, generally called spacetime. It is the fourth dimension in which you move through both space and time.

What is the equation for space time?

The space-time interval equation is this: Where, $\\Delta x, \\Delta y, \\Delta z$ and $\\Delta t$ represent the distances along various coordinates according to an observer, and $\\Delta s$ is the space-time interval.

What is the meaning of space and time?

In “time and space”, time refers to “as time goes by” as you have said. Space refers to geography, e.g. different countries, areas, regions, and movements of people across them. Thank you very much. I confess to never having heard the expression “over time and space” used in this way.
