... The total mass left is 3000 kg, the total weight is 30,000 newtons, so a = F/m = (240,000 - 30,000) / 3000 = 210,000 / 3000 = 70 m/s 2 = 7g. --In some weird alternate universe, weight and mass are not proportional. ...
... Also of this type is the distribution of microwave radiation left over from the "big bang" when the universe apparently began, a radiation observed by NASA's COBE satellite, the Cosmic Background Explorer. ...
... Primordial microwaves A diffuse microwave radiation apparently filling the entire universe, a remnant of gamma rays emitted by the " primordial fireball " in the early universe, following the "Big Bang." ...
... Viewed from the frame of the moving Earth, the rest of the universe had a velocity ?u , perpendicular to the velocity c of light coming from Polaris. ...
... Yet we have abundant evidence that ions and electrons in space are indeed accelerated to high energies, all over the universe: in flares and CMEs near the Sun, in elusive "substorms" of the magnetosphere, in the radiation belts of Jupiter and other ...
... In Gilbert's age, his claim that the Earth was not the immovable center of the universe--and his strong support, voiced in his book, of the theory of Copernicus--were, in some circles at least, articles of heresy. ...
... Heat is the "soft currency" of the energy universe: it is possible to convert heat to other forms of energy (in a steam engine, for instance), but one can never get the full value. ...
