Black hole effect on gravity
Did you know?
In astrophysics, spaghettification (sometimes referred to as the noodle effect) is the vertical stretching and horizontal compression of objects into long thin shapes (rather like spaghetti) in a very strong, non-homogeneous gravitational field. It is caused by extreme tidal forces. In the most extreme cases, near a black hole, the stretching and compression are so powerful that no object ca… WebAug 1, 2024 · If one tries to generate a solution in semiclassical gravity similar to the eternal black-hole configuration, one encounters a well-known obstacle: the RSET in the Boulware vacuum state, the only genuine vacuum consistent with staticity and asymptotic flatness, diverges at the Schwarzschild horizon.

It makes up only about a millionth of the … WebThe gravity of a black hole is really powerful up close, but from a distance, it’s no different than that of anything else with a comparable mass. Even up close, the gravity is the …
WebHořava has proposed a renormalizable gravity theory with higher spatial derivatives in four dimensions. This theory may be regarded as a UV complete candidate for general … WebBlack holes are some of the most fascinating and mind-bending objects in the cosmos. The very thing that characterizes a black hole also makes it hard to study: its intense …
WebA gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer that is capable of bending the light from the source as the light travels toward the observer. This effect is known as gravitational lensing, and the amount of bending is one of the predictions of Albert Einstein 's ...
