Just how big is space?

Edición de la obra Just how big is space?

"Reveals the immensity of space by showing how its distances are measured and by examining the effects of Einstein's Theory of Relativity on space travel. Topics include parallax calculations, the inverse square law of light brightness, the Cepheid variable, Doppler shift, time dilation, space dilation, and the distorting effect of gravity on the space time continuum."--Container.
