Does Gravity 'Push' or 'Pull?'

Einstein suggested that objects aren’t pulled by massive objects, but rather pushed down by the space above them. According to General Relativity, matter warps the fabric of not only space but time as well, collectively known as the continuum of space-time. The fabric is like a grid of tightly strung rubber bands; when a massive object pushes and stretches them downward, the deformed rubber bands push objects under them. The theory implied that smaller objects weren’t pulled towards massive objects but were traveling on a downward slope, as the space in the latter’s vicinity was warped by its large mass. A free-falling body, therefore, follows the straightest possible path in space-time. In other words, gravity is neither a push nor a pull; what we interpret as a “force” or acceleration due to gravity is actually the curvature of space and time — the path itself stoops downward. #gravity #fundamentalforces #pushpull References: http://web.archive.org/web/2021111421... https://vis.sciencemag.org/generalrel... https://iopscience.iop.org/article/10...
