Gravitational red shifts
WebThe first time that astronomers observed both gravitational waves and electro-magnetic waves from the same event, what they were observing was: a. a supernova explosion in one of the closest galaxies to us b. the spiraling toward each other of two neutron stars c. a binary star system where a giant star is overloading a white dwarf with too much material … WebNov 15, 2024 · A gravitational lens is a potential; a photon will gain energy as it falls through (i.e. gets blueshifted) and has to give up the same amount as it gets out of that …

WebMainly, to distinguish gravitational redshifts from other kinds, you compare the size of the object with its mass to determine how much larger it is than its black hole radius. Objects like nebulae and entire galaxies are trillions of times larger than their BH radius, so the magnitude of the redshift is 1 part in a trillion of the rest frequency. A gravitational redshift can also equivalently be interpreted as gravitational time dilation at the source of the radiation: if two oscillators (attached to transmitters producing electromagnetic radiation) are operating at different gravitational potentials, the oscillator at the higher gravitational potential … See more In physics and general relativity, gravitational redshift (known as Einstein shift in older literature) is the phenomenon that electromagnetic waves or photons travelling out of a gravitational well (seem to) lose See more The gravitational weakening of light from high-gravity stars was predicted by John Michell in 1783 and Pierre-Simon Laplace in 1796, using Isaac Newton's concept of light corpuscles (see: emission theory) and who predicted that some stars would have a gravity so strong … See more Uniform gravitational field or acceleration Einstein's theory of general relativity incorporates the equivalence principle, which can be … See more Astronomical observations A number of experimenters initially claimed to have identified the effect using astronomical … See more • Tests of general relativity • Equivalence principle • Gravitational time dilation • Redshift See more
WebA sprinter named Ben has challenged a beam of light to a race in the 100-m dash. The race is held in a stadium full of spectators. At the start signal, a laser beam is turned on at the start line, pointed down the track. At the same instant, Ben bursts out of the starting blocks at 99% of the speed of light (0.99c). Web1. Gravitational redshift: Pound-Rebka Experiment. Consider an experiment (cartoon below, at right) in which a laser is directed upward from the bottom tro the top of a lab in space which is unformly accelerating upward with acceleration a = - g.Assume at the instant the laser pulse starts, the lab is a rest (v=0).
