I will gladly explain the difference between Einstein's Theory of special relativity and general relativity and provide visual aids to simplify the concepts for you.

Einstein's Theory of Special Relativity deals with the laws of physics in frames of reference that are moving at a constant velocity relative to each other. One of its key ideas is that the speed of light in a vacuum is always constant, regardless of the relative motion of the observer or the source of light.

On the other hand, General Relativity is a theory that deals with the effects of gravity on the fabric of space-time. According to this theory, gravity isn't a force that one object exerts on another, but rather a curvature of space-time caused by the presence of massive objects.

To help you visualize these concepts, I have created the following two examples:

The Light Clock

One way to understand special relativity is to consider the difference in the passage of time between two observers in different frames of reference. The Light Clock is a visual aid that shows how time dilation works in special relativity. It consists of a beam of light bouncing between two mirrors that are set a fixed distance apart. To an observer who is stationary relative to the mirrors, the light bounces up and down in a regular pattern. However, to an observer in motion relative to the mirrors, the light appears to travel a longer distance than it would if the observer were stationary. This means that time appears to pass more slowly for the moving observer.

: The Space-Time Curve

General relativity deals with the curvature of space-time caused by the presence of massive objects. To visualize this, imagine a flat rubber sheet that represents space-time. If you place a heavy object on the sheet, it will cause a depression in the sheet. This represents the curvature of space-time caused by the object's mass. Objects that are nearby will be attracted to the object because they follow the curvature of space-time.
