Simplicity is the touchstone in finding new physical laws. … If it's elegant, then it's a rough rule of thumb: you're on the right track. - Kip S. Thorne

First, a weird claim: Black holes are made from warped space and warped time. Nothing else — no matter whatsoever.

cuando un cálculo confirma las propias expectativas, uno simplemente se reafirma un poco en su comprensión intuitiva de las leyes de la física. Pero cuando un cálculo contradice las expectativas, uno está en el camino hacia una nueva intuición.

[B]y reason of its faster and faster infall [the surface of the imploding star] moves away from the [distant] observer more and more rapidly. The light is shifted to the red. It becomes dimmer millisecond by millisecond, and in less than a second is too dark to see . . . [The star,] like the Cheshire cat, fades from view. One leaves behind only its grin, the other, only its gravitational attraction. Gravitational attraction, yes; light, no. No more than light do any particles emerge. Moreover, light and particles incident from outside ... [and] going down the black hole only add to its mass and increase its gravitational attraction.” Black hole was Wheeler’s new name. Within months it was adopted enthusiastically by relativity physicists, astrophysicists, and the general public, in East as well as West — with one exception: In France, where the phrase trou noir (black hole) has obscene connotations, there was resistance for several years.
