A Four-Dimensional Travel in the Known Universe

A virtual three-dimensional journey, along with the fourth dimension - time, beginning in the Himalayas and ending at the verge of the known universe, with a magnificent afterglow of the Big Bang. A wonderful video from the American Museum of Natural History.

It might be beneficial to assist the kids with a little explaining, though an "innocent" viewing will be just as impressive at any age...!

Thanks for this reference to my friend Heidi Cool!
