Black Holes ExplainedOverviewImagine a region in space where the force of gravity is so strong that nothing—not even light—can escape.

A region so dense that an object as tiny as a walnut would have the same mass as our entire planet.First airedMay 1, 2009URL slugblack-holes-explainedGenres다큐멘터리아트워크포스터배경이미지 없음아이콘이미지 없음배너시즌스페셜에피소드 0개시즌 1에피소드 12개출연진 및 제작진
