Abstract. Throughout its journey universe follows strong gravity. By unifying general theory of relativity and quantum mechanics a simple derivation is given for rotating black hole's temperature. It is shown that when the rotation speed approaches light speed temperature approaches Hawking's black hole temperature. Applying this idea to the cosmic black hole it is noticed that there is $``$no cosmic temperature" if there is ``no cosmic rotation". Starting from the Planck scale it is assumed that - universe is a rotating and expanding black hole. Another key assumption is that at any time cosmic black hole rotates with light speed. For this cosmic sphere as a whole while in light speed rotation ``rate of decrease" in temperature or ``rate of increase" in cosmic redshift is a measure of ``rate of cosmic expansion". Since 1992, measured CMBR data indicates that, present CMB is same in all directions equal to 2.7260 kelvin smooth to 1 part in 100000 and there is no continuous decrease! This directly indicates that, at present rate of decrease in temperature is practically zero and rate of expansion is practically zero. Universe is isotropic and hence static and is rotating as a rigid sphere with light speed. At present galaxies are revolving with speeds proportional to their distances from the cosmic axis of rotation. If present CMBR temperature is 2.7260 kelvin, present value of obtained angular velocity is 2.17× 10^-18 rad/sec = 67 Km/sec/Mpc. Present cosmic mass density and cosmic time are fitted with natural logarithmic ratio of cosmic volume and planck particle's volume. Finally it can be suggested that dark matter and dark energy are ad-hoc and misleading concepts. (Planck particle can be considered as the baby universe).
