Comparing these relations with the observed one derivedfrom the redshift of EXO 0748-676, we come to the conclusion that it is incorrectto say that EXO 0748-676 cannot be a strange star. Various strange star modelscan show that EXO 0748-676 could have a mass of (1.3 ~ 1.7) M and a...
What is redshift? Define a ray of light. Explain the difference between intensity and solar constant. What is the evidence that light is energy? What the speed of the dark? What is meant by the polarization of light? What is a spectrum ?
In summary, the formula for gravitational redshift is frequency2 = function(frequency1, radius1, radius2, gravitating_mass). The redshift factor for radius2 is infinity, but it can be calculated by dividing the redshift at infinity with the redshift between r1 and r2. Addition...
Both redshift and blueshift are determined by studying the spectrum of light radiated from the object. Specifically, "fingerprints" of elements in the spectrum (which is taken with a spectrograph or a spectrometer), are "shifted" toward the blue or red depending on the motion of the object. ...
Redshift and blueshift describe the change in the frequency of a light wave depending on whether an object is moving towards or away from us.
Tifft that galaxy redshifts come in bunched intervals rather than on a smooth continuum. Difficulties in measuring redshifts; Example of why Tifft's claims are unusual; Reports of studies that seem to confirm Tifft's claims; Other claims on Tifft. 年份: 1992 ...
My answer: gravitational redshift has nothing to do with the theory of relativity, it can be well explained by classical physics, why do you think it is due to the theory of relativity? Gravitational Lensing: The theory of relativity predicts that the path of light should be bent by the ...
