The results point to gaps in our knowledge of space-time and dark energy, but they do not refute Einstein's theories. According to Albert Einstein's theory, the Universe is deformed by matter ...

This dimple in space-time is the result of what we call a gravity well, and it was first described over 100 years ago by ...

The James Webb Space Telescope has identified the first-ever "Einstein zig-zag," a distant quasar lensed six times by two ...

But if the speed of light is identical for all observers, something else has to give: absolute time and space. Einstein concluded that the cosmos has no universal clock or common reference frame.

We spoke with theoretical physicist Brian Greene about Einstein's theory of space-time. Many scientists believe space-time is a fundamental concept. But Greene thinks there might be something ...

Using the James Webb Space Telescope, astronomers have discovered the first "Einstein zig-zag," an image ... in the very fabric of space and time, united as a single entity called "spacetime." ...

This difference arises from Einstein's introduction of a key new element: the deformation of time, in addition to the deformation of space, to achieve the exact curvature of light. Are these ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...
