Do physical laws limit the speed of “all data processing systems, manmade as well as biological”? A positive answer, proposed by H. J. Bremermann in 1962, should be corrected to make it compatible with Einstein’s theory of gravity (aka general relativity, or GR). As a result, the Bremermann’s limit, proportional to mass M of the computer, Mc 2 /h = ~ (M/gram)10 47 bits per second, should be replaced by the absolute limit (c 5 /Gh) 1/2 = ~ 10 43 bits per second, where the universal constants c, G, and h are the speed of light, the gravitational constant, and Planck’s constant.
