Black holes may give us a glimpse of the underlying nature of reality.

- Since energy cannot be destroyed, only transformed, some argue that information — arguably a form of energy — cannot be destroyed either. So then, what happens to information when it is absorbed into a black hole? Scientists don't know for certain, but some posit that it may be possible for it to leak away from the black hole over time.

- Black holes may hold information in a two-dimensional manner similar to a hologram, which take on three dimensions when light is shone through them. Some theorize that the underlying nature of reality can be glimpsed through black holes — that all the information about the entire universe is somehow held on a two-dimensional space of something.

- To better understand how black holes work, as well as the elements surrounding them, we may need a level of physics to be developed.

Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars. She is Assistant Director of Science Communication at NASA. She went to college at Harvard University, completed a post-doctoral research fellowship at the California Institute of Technology (Caltech) in Pasadena, Calif. then started working for the Jet Propulsion Laboratory's (JPL) Spitzer Space Telescope. After a hugely successful mission, she moved on to NASA's Goddard Space Flight Center (GSFC), in the Washington D.C. area. In her off-hours often puts on about 30lbs of Elizabethan garb and performs intricate Renaissance dances. For more information, visit NASA.
