    Einstein's description of curved space-time doesn't easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.

    Is space-time flat or curved, static or dynamic, finite or infinite? Minkowski space-time is flat, static and infinite. Einstein worked for a decade to understand how the force of gravity could be incorporated into his theory.

    Jan 14, 2025Relativity - Curved Space-Time, Geometric Gravitation: The singular feature of Einstein's view of gravity is its geometric nature. (See also geometry: The real world.) Whereas Newton thought that gravity was a force, Einstein showed that gravity arises from the shape of space-time. While this is difficult to visualize, there is an analogy that provides some insight—although it is only a ...

    In the descriptions of gravity we have looked at so far, we have left off one important part: What is the source of spacetime curvature? We have described what curvature is, at least in a basic sense, and we have described how curvature affects the motion of particles and the perceptions of space and time that different observers have. But where does the curvature actually come from? This is ...

    The main takeaways behind Einstein's general theory of relativity: 1. Time and space are neither flat nor fixed; they are curved and distorted by mass and energy. 2. Gravity is not a force, but rather a distortion of time and space. 3. The effects of gravity are indistinguishable from the effects of acceleration, over a small space.

    Then, over the next decade, he worked to incorporate gravity into this picture. The result was general relativity. At its most basic, general relativity is a way to describe gravity by attributing it to the curvature of space-time that occurs in the presence of massive bodies. Massive objects cause space-time to stretch.
