Does gravity bend space or light?

Answer 2: Light has energy, energy is equivalent to mass, and mass exerts gravitational force. Thus, light creates gravity, i.e. the bending of space-time.

How is it possible for the path of light to be bent by gravity?

When photons travel through the region near a massive object that has caused significant warping, they follow curved paths because the space-time through which they are moving is curved. While it is true that photons have no mass, it is also true that we see light bend around sources with high mass due to gravity.

What will happen to the speed of light when it moves against the gravitational field?

Answer: The short answer is no, the speed of light is unchanged by gravity. If for example light travels from a distant star to Earth and passes by a black hole, the path of the light will get bent as it passes by the black hole, which will lengthen its travel time. The actual speed of light, though, is unchanged.

How does gravity bend time in space?

Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. 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.

Does gravity move at speed of light?

The speed of gravity has been measured for the first time. The landmark experiment shows that it travels at the speed of light, meaning that Einstein’s general theory of relativity has passed another test with flying colours.

Why does light bend in a gravitational field?

Originally Answered: Why is light bent by gravity? Light travels in a straight line geodesically. So when gravity bends spacetime, it bends the very fabric in which that light travels through. Therefore, light has to pass through the path with the least resistance, which is the curvature of spacetime as it is bent.

What is the curvature of space-time?

The curvature of spacetime influences the motion of massive bodies within it; in turn, as massive bodies move in spacetime, the curvature changes and the geometry of spacetime is in constant evolution. Gravity then provides a description of the dynamic interaction between matter and spacetime.

Does light bend in a gravitational field?

But that bending is not gravitational; it’s electromagnetic. However, light does bend when travelling around massive bodies like neutron stars and black holes. This is explained by Einstein’s theory of general relativity. We are all familiar with massive objects being influenced by gravity.

How will light be affected by gravity?

According to Einstein’s General Relativity Theory,light will be affected in the same way matter is affected by gravity.

Why is the path of light curved?

Light also travels along geodesics (called null geodesics), and so paths of light are also curved by gravitational force, despite the light not having any mass. There is some more cutting-edge research related to this answer. There is reason to believe that light itself curves spacetime in the same way that massive objects do.

Why does light curve spacetime?

There is reason to believe that light itself curves spacetime in the same way that massive objects do. This is sometimes referred to as the self-gravitation of light. The idea is that an electromagnetic wave has a non-zero energy-momentum tensor, and should therefore curve spacetime, albeit in a small and strange way.
