How does mass curve spacetime
WebDec 11, 2010 · The curvature of spacetime (not just space) is responsible for gravity. Literally, near heavy objects, the “future direction” points slightly down. So anything that moves forward in time will find its trajectory pointing down slightly. This takes the form of downward acceleration. WebJust to nitpick -- spacetime is never Euclidean, but can be pseudo-Euclidean. What you mean is that 4D spacetime is flat in the absence of mass-energy (that is, it is a Minkowski space). 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”.

Some of the forms of mass-energy … Web42–1Curved spaces with two dimensions According to Newton everything attracts everything else with a force inversely proportional to the square of the distance from it, and objects respond to forces with accelerations proportional to the forces. They are Newton’s laws of universal gravitation and of
WebMar 11, 2016 · In general relativity, the curvature of spacetime is an interpretation of the model for gravity: Starting with the assumptions of gravity being equivalent to acceleration, and the speed of light being constant, a mathematical framework that … WebSpace is indeed curved -- in four dimensions. Many people think the fourth dimension is simply time, and for some astronomical equations, it is. Einstein used time as a fourth dimension to describe a coordinate system called space-time. This is the stage on which planets, stars, galaxies -- all matter in the universe -- act their gravitational ...
WebMar 2, 2016 · Since the curvature of spacetime is dynamical, moving objects should create ripples in space that permeate through the universe. Most of these ripples are too small to notice, but the more extreme the event, the higher the chance we can detect it. What is a super moon, blood moon or blue moon? Space.

WebAug 15, 2015 · In the absence of an external force, objects travel along the straightest possible paths, geodesics, through spacetime. In the absence of gravity, those paths look like the straight lines we’re all used to. But in the presence of mass, they can look very curved. That, my friends is the gravitational “force.” And let’s be clear. It’s nota force! cannot scan from my hp printerWebWe examine spacetime a bit more closely in the next subsection.
