"Microsoft took over Caligari TrueSpace earlier last year and later released the software as freeware. They have now decided to discontinue TrueSpace - the first services will be disabled by tomorrow. This is a truly sad day for their loyal user base."
"Thorne calculated the effects of gravitation on objects of different shapes (spheres, and cylinders that are infinite in one direction), and concluded that the object needed to be compressed in all three directions before gravity led to the formation of a black hole. With cylinders, the event horizon was formed when the object could fit inside the hoop described above. The mathematics to prove the same for objects of all shapes was too difficult for him at that time, but he formulated his hypothesis as the hoop conjecture."
"the AdS/CFT correspondence (anti-de-Sitter space/conformal field theory correspondence), sometimes called the Maldacena duality, is the conjectured equivalence between a string theory defined on one space, and a quantum field theory without gravity defined on the conformal boundary of this space, whose dimension is lower by one or more."
"Algebraic holography, also sometimes called Rehren duality, is an attempt to understand the holographic principle of quantum gravity within the framework of algebraic quantum field theory,"
"The ergosphere is a region located outside a rotating black hole. Its name is derived from the Greek word ergon, which means 'work'. It received this name because it is theoretically possible to extract energy and mass from the black hole in this region."
