WebApr 10, 2024 · In 2024, four astronomers led by Qi-Qi Zhou used 37 groups of multiwavelength polarization measurements collected from five blazars, spanning a distance range from 1.5 to 4.7 billion light-years, to establish stringent constraints on possible Lorentz invariance violations. 11 If Lorentz invariance is violated, the group velocities of left- and ... An alternative expression for the escape velocity particularly useful at the surface on the body is: where r is the distance between the center of the body and the point at which escape velocity is being calculated and g is the gravitational acceleration at that distance (i.e., the surface gravity). For a body with a spherically symmetric distribution of mass, the escape velocity from the surface is proportional to the radius assuming constant density, and proportional to the square root of th…

WebIt has been stated that the Tully-Fisher (TF) relation is the ``workhorse'' of peculiar velocity surveys. One can anticipate a time in the not so distant future when more accurate techniques may supplant it, but for the next few years at least, the TF relation is likely to remain the most widely used distance indicator in cosmic velocity studies.

Time dilation effects become important when an object approaches speeds on the order of 30,000 km/s (1/10 the speed of light). The formula for determining time dilation is: Δt′ = Δt √1 − v2 / c2.
