We mention in the text that gravitational redshifts can be observed and measured during the collapse of a star into a black hole. When might the redshifts cease?

Gravitational redshift is that phenomenon during which electromagnetic waves or photons travelling out of a gravitational well lose energy. This loss of energy corresponds to a decrease within the wave frequency and increase within the wavelength referred to as a redshift. The other effect, whereby photons gain energy when travelling into a gravitational well, is understood as a gravitational blueshift. The effect was first described by Einstein in 1907.
Gravitational redshift are often interpreted as a consequence of the equivalence principle or as a consequence of the principle though there are numerous subtleties that complicate a rigorous derivation.
A gravitational redshift also can equivalently be interpreted as gravitational time dilation at the source of the radiation, if two oscillators are operating at different gravitational potentials, the oscillator at the upper gravitational potential will seem to tick faster that's, when observed from an equivalent location, it'll have a better measured frequency than the oscillator at the lower gravitational potential.
Einstein argued that gravity isn't a force in the least. He described it as a curvature of your time and space caused by mass and energy. Their math, laid down in 10 equations, explained how gravity could move around objects via a warped reality, accelerating without ever feeling any mysterious Newtonian forces.
Gravitational waves are ripples in space-time caused by a number of the foremost violent and energetic processes within the Universe. Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.
