WebAug 3, 2010 · To observe the so-called red shifts and blue shifts over time, planetary scientists use a high-resolution prism-like instrument known as a spectrograph that separates incoming light waves into different colors. ... But if there is a planet or companion star in the system, the gravitational pull of this unseen body or star will perturb the host ... WebThe observer must be in a higher gravitational potential than the light source in order to observe red-shifted light (e.g., in an airplane, looking down). What is in between (for example a ...
How can we explain the gravitational blueshift according to the ...
Web3) the bursts are not associated with planets in our solar system. 4) the bursts were not produced in our Sun. 5) All of the above. Hypernovae are. 3) supernovae that occur when stars more massive than 25 solar masses explode. 4) one theory to explain the production of gamma ray bursters. 5) both 3 and 4 above. The GPS satellite gravitational blueshift velocity equivalent is less than 0.2 m/s, which is negligible compared to the actual Doppler shift resulting from its orbital velocity. In astronomical objects with strong gravitational fields the redshift can be much greater; for example, light from the surface of a white dwarf … 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 Astronomical observations A number of experimenters initially claimed to have identified the effect using astronomical measurements, and the effect was considered to have been finally identified in the spectral lines of the star Sirius B See more • Tests of general relativity • Equivalence principle • Gravitational time dilation See more Uniform gravitational field or acceleration Einstein's theory of general relativity incorporates the equivalence principle, which can be stated in various different ways. One such statement is that gravitational effects are locally undetectable for a … 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 the other wes moore by wes moore book
