Chandra’s coma

Recent observations from NASA’s Chandra observatory that shows the enormous scope of the Coma cluster of galaxies leave the amateurs dumfounded. The features of this epic structure, spanning over half a million light years, cannot be easily explained. The marriage of at least two giant elliptical galaxies has resulted in a structure of fantastic scale, held in shape, apparently by gravity.

The observation of such structures, ironically, raises more questions than answers. The paradoxical information loss in a black hole, sometimes explained away by the pasting on the surface, leading to the possibility of the universe being a hologram, may need to be revisited. The question is whether peeking into the past is a fruitful activity – does it provide new information or just cloud already established ignorance?

It may be time to look to the future, for the past is too dull or inexplicable with available tools.
