Actually how much light has disappeared? According to the new study, a group of international experts is sponsored by the US Aerospace Agency (NASA), the Natural Science Foundation and the Ahmanson Foundation, and cannot get clues from about 80% of the population. light in the whole universe.'As if you were in a large and flooded room, but only a few 40W bulbs were finally found , ' Space.com quoted an astronomer - lead researcher Juna Kollmeier (Carnegie Science Institute, America). 'Those lights have disappeared from our survey'.

Professor Kollmeier and colleagues published their report in the latest issue of The Astrophysical Journal Letters. Together with Benjamin Oppenheimer and Charles Danforth of the University of Colorado Boulder, Ms. Kollmeier said, the amount of light emitted from ionized spiral-shaped hydrogen gases is only a fraction of what should have been.

On the Universe Today website, collaborator Shannon Hall explains: 'N large spaces in space are connected by strips of hydrogen and helium. However, there is a disruption of light between the large structure of the universe as well as the expected brightness. ' Experts call the phenomenon of light loss as 'crisis producing weak photons'.
