Is gravity a force or the curvature of spacetime?
Gravity is the curvature of spacetime Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects.
Does gravity effect space time?
The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds. Time itself is slowing down and speeding up because of the relativistic way in which mass warps space and time.
Is gravity a force or an effect?
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.
Is gravity actually curved space?
If gravity is actually curved space and if falling objects are simply following the natural curves of space why does each object have its own curve? This is a great question which goes to the heart of why Einstein said gravity is the curvature of space-time, rather than just the curvature of space.
Is gravity a force of attraction or curvature?
Based on this thought experiment, Einstein concluded that gravity is not a force of attraction, for no such force is required. Instead, it is something quite different — a curvature in the fabric of space-time.
Is gravity the warping of space and time?
The equivalence principle tells us that the effects of gravity and acceleration are indistinguishable. In thinking about the example of the cylindrical ride, we see that accelerated motion can warp space and time. It is here that Einstein connected the dots to suggest that gravity is the warping of space and time.
Is gravity a force of gravity?
Gravity would not be an attractive force between masses but an external pressure force produced by the spacetime curvature. A rational explanation of many enigmas of physics is also given in that webpage: faster-than-light neutrinos, time dilatation, mass of relativistic particles, E = mc², black holes… (See the copyright) Part 1
