How do you imagine space time?

Space-time, is in a way, any model which connects the 3 spatial dimensions with the flexible dimension of time – as the fabric does. The second way, is to actually imagine a 4 dimensional object, like a tesseract or hypersphere. Take a look at a tesseract. It’s a cube with one added dimension – the dimension of time.

What is space time in general relativity?

In general relativity, spacetime is no longer a static background, but actively interacts with the physical systems that it contains. Spacetime curves in the presence of matter, can propagate waves, bends light, and exhibits a host of other phenomena.

How did Einstein view space time?

Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends the spacetime blanket with its gravity, such that light no longer travels in a straight line as it passes by the Sun.

Can we see space time?

We can no more observe the ‘fabric of space’ than we can observe the nothingness of empty spacetime; it simply exists. Any visualization we attempt to assign to it, whether it’s a 2D fabric, a 3D grid, or a baking ball of dough, is just that: a human-inspired creation. The theory itself doesn’t demand it.

Why is it so hard to visualize the curvature of spacetime?

You are asking why it is so hard to visualize spacetime curvature, because it is four dimensional.

What is the general theory of relativity?

SPACETIME & GRAVITY: The GENERAL THEORY of RELATIVITY We now come to one of the most extraordinary developments in the history of science – the picture of gravitation, spacetime, and matter embodied in the General Theory of Relativity (GR).

How was Einstein’s theory of relativity revolutionary?

This theory was revolutionary in several difierent ways when flrst proposed, and involved a fundamental change how we understand space, time, and flelds. It was also almost entirely the work of one person, viz. Albert Einstein.

How do we see the curvature of the universe on a map?

The same way you see the curvature of the Earth on a flat map, through local scaling distortions of the map. Here is a map of a universe with positive curvature. The central galaxy is undistorted, but greater distortion is seen further from the centre. The “outermost” galaxy goes right round the map.
