What Everyone Gets Wrong About Gravity
General relativity treats gravity not as a force field but as a consequence of curved spacetime—so “weight” and “acceleration” depend on what an...
General Relativity & Curved Spacetime Explained! | Space Time | PBS Digital Studios
General relativity resolves the “gravity illusion” paradox by replacing Newton’s global inertial frames with a geometry where inertial behavior only...
Can a Circle Be a Straight Line?
Gravity’s “no-force” framing in general relativity hinges on a geometric idea: motion follows straightest-possible paths in curved spacetime, not...
Can You Trust Your Eyes in Spacetime?
Spacetime diagrams can look like they’re playing tricks on geometry, but the underlying rule is consistent: they preserve the spacetime interval...
Curvature Demonstrated + Comments | Space Time | PBS Digital Studios
The core takeaway is that “geodesic” on a curved surface isn’t a definition-by-handwaving—it’s the specific curve that preserves a tangent direction...
