Could you please give me some brief explanation of the attraction of light by gravity. Or maybe some links where I can read something about it. :)
Thank you!
Thank you!
Larry717 said:I once read that light is slowed down by a gravitational field.
Later, I read that spacetime contorts and c remains the same.
Which is true?
L.A.
The attraction of light by gravity is a phenomenon predicted by Einstein's theory of general relativity. It suggests that light, which has no mass, can still be affected by the gravitational pull of massive objects, causing it to bend as it passes through space.
According to general relativity, gravity is not just a force between massive objects, but it is the curvature of space and time caused by the presence of mass and energy. As light travels through this curved space, it follows the path of least resistance, which can be influenced by the presence of massive objects.
Yes, the attraction of light by gravity is the same as gravitational lensing. Gravitational lensing is the bending of light by the gravitational pull of massive objects, and it is a direct consequence of the attraction of light by gravity predicted by general relativity.
While the attraction of light by gravity is a significant phenomenon in the universe, it cannot be observed in everyday life. This is because the gravitational pull of everyday objects, such as the Earth, is too weak to noticeably affect the path of light.
The attraction of light by gravity is crucial in understanding and studying the behavior of light in the presence of massive objects in the universe. It has been used to explain various observations, such as the bending of starlight near the Sun and the creation of multiple images of distant objects by massive galaxies. It also plays a significant role in the study of dark matter and dark energy, which are thought to make up a majority of the universe's mass and energy.
