Just How Big Is Space?

Streaming Video - 2006
Rate this:
This video reveals the immensity of space by showing how its vast distances are measured and by examining the strange effects of Einstein's Theory of Relativity on space travel. Topics include the units of measure in astronomy; how scientists estimate distances through parallax calculations, the inverse square law of light brightness, and the Cepheid variable, Doppler shift, and supernova methods; and time dilation, space dilation, and the distorting effect of gravity on the space-time continuum-all things to take into account as we study the universe.
