Pingback: Q: Why does “curved space-time” cause gravity?: A better answer. « Ask a Mathematician / Ask a Physicist Yoron says: June 30, 2011 at 1:01 am I’m not sure i follow this explanation. It’s simple to see that you can have two parallel lines on a globe too. The...
In almost all cases the vast majority of an object’s movement is tied up in its forward movement through time. 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 forw...
Time is absolute in standard quantum theory and dynamical in general relativity. The combination of both theories into a theory of quantum gravity leads therefore to a "problem of time". In my essay, I investigate those consequences for the concept of time that may be drawn without a detailed...
Einstein also says this occurs due to gravity — but in his theory, gravity is not a force. It's a curve in space-time. According to Einstein, those objects are still traveling along the straightest possible line, but due to a distortion in space-time, the straightest possible line is...
