I am not sure.
Hurkyl said:I'm not the person to turn for GR semantics. But yes, what I said is an inertial coordinate chart is one that would be appropriate for the rest frame of an inertial observer.
Yes, spacetime curvature can affect the speed of light. In Einstein's theory of general relativity, gravity is described as the curvature of spacetime. This means that the path of light is also affected by the curvature of spacetime, causing it to appear as if it is changing its speed.
Spacetime curvature can cause the speed of light to vary depending on the strength of the gravitational field. In areas of strong curvature, the speed of light can slow down, while in areas of weak curvature, it can speed up. This is because spacetime curvature affects the geometry of space, which in turn affects the path of light.
Yes, in a vacuum, the speed of light can change due to spacetime curvature. This is because even in a vacuum, there is still spacetime curvature caused by the presence of massive objects such as stars and galaxies. This curvature can change the speed of light as it travels through the vacuum.
No, the speed of light is not affected equally by all types of spacetime curvature. The strength of the gravitational field, which is determined by the mass and density of an object, determines the amount of curvature. Therefore, the speed of light can be affected differently depending on the strength of the gravitational field.
No, the value of the speed of light is a fundamental constant in the universe and cannot be changed by spacetime curvature. However, the perceived speed of light can vary due to the effects of spacetime curvature, as discussed in the previous questions. The speed of light will always be constant in a vacuum, regardless of the curvature of spacetime.
