In geocentric universe of Aristotle and Ptolemy, orbits of Moon, Sun and five planets (Mercury, Venus, Mars, Jupiter, Saturn) circle Earth:
Outermost text reads: celum empireum habitaculum dei et omnium electorum (heavenly empire, dwelling of God and all the selected).

Collaboration between Stephen Hawking and Sir Roger Penrose (born 8 August 1931) has transformed modern understanding of the universe, especially of black holes.

Multiplicity of dimensions may baffle imaginations: Stephen Hawking easily conceives of 11 dimensions.

Black holes have beguiled such astrophysical geniuses as Albert Einstein and Stephen W. Hawking.
Visualization of Einstein's general theory of relativity: Simulation of three-dimensional merging black holes by crunching Einstein's theory into NASA supercomputer constitutes largest astrophysical calculation ever performed on NASA supercomputer.

Dr. Hawking is one of my first two choices, tied for first place, for any astrophysics-illuminating publications even as Dr. Brian May, also of Queen, is the other ;-D.

Me too, I find string theory a bit frustrating even as Dr. Hawking furnishes us fruitful ways to fight that personal and professional fulfillment not formed -- like him! -- by fluent astrophysics.
Isn't it impressive that Dr. Hawking is able to imagine at least 11 dimensions?
