... Bad Astronomy . Misconceptions . ... Bad Astronomy : If the Sun collapses into a black hole, the Earth and all the other planets will get sucked in. Good astronomy : If the Sun were to collapse into a black hole, we would feel no difference in the gravity as measured at the Earth. ... The same applies if the Sun were to collapse into a black hole. ... Therefore, the gravity of the Sun felt at the Earth would remain the same. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...

... The light baffles consist of the wind baffle that surrounds the telescope and doubles as a light baffle, the primary baffle that extends from the primary center-hole toward the secondary (left), the secondary baffle that extends from the perimeter of the secondary toward the primary (right), and the conical baffle that is suspended approximately halfway between the primary and secondary (middle). The wind baffle is covered with panels that are 25% porous to the wind. ...

Tired light models invoke a gradual energy loss by photons as they travel through the cosmos to produce the redshift-distance law. ... The tired light model can not produce a blackbody spectrum for the Cosmic Microwave Background without some incredible coincidences. ... So the CMB must have come from a far away part of the Universe, and its photons will thus lose energy by the tired light effect. ...
