The latest image from NASA's James Webb Space Telescope, pictured above, also happens to be a stunning illustration of Einstein's theory of general relativity ... with the curve itself being gravity.

Expanding his special theory, Einstein’s general theory of relativity states that what we perceive as the force of gravity between two masses actually arises from their warping of space and time.

The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known ... added to his theory of general relativity ...
