WebApr 13, 2024 · However, Einstein proposed that both space and time were one force, spacetime, and that matter within this ever-changing stage was controlled by the curving path that gravity dictated. But to create gravity, we needed mass, a force so strong it could literally curve spacetime around it. This is where dark matter comes into play. WebObjects are falling to the floor because the room is aboard a rocket in space, which is accelerating at 9.81 m/s 2, the standard gravity on Earth, and is far from any source of gravity. The objects are being pulled towards the floor by the same "inertial force" that presses the driver of an accelerating car into the back of their seat. tactile coffee

Gravity is described as bending space, but how does that bent space …

WebIn general relativity, gravity can be regarded as not a force but a consequence of a curved spacetime geometry where the source of curvature is the stress–energy tensor (representing matter, for instance). Thus, for example, the path of a planet orbiting around a star is the projection of a geodesic of the curved 4-dimensional spacetime ... In physics, gravity (from Latin gravitas 'weight' ) is a fundamental interaction which causes mutual attraction between all things with mass or energy . Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 times weaker than the strong interaction, 10 times weaker than the electromagnetic force and 10 times weaker than the weak interaction. As a result, it has no sign… WebOct 13, 2024 · In your curvature model, you're assuming that moving through some 3D spatial point in one spatial 3D direction will experience the same 3D path curvation independent on speed (as if you'd shoot a ball through a curved tube). You'd certainly agree that a different initial 3D direction will result in a different path. tactile childrens books
