Max Plank Institute: How transparent is the universe?

suchandra · 01-25-2009, 01:29 PM

According Srimad Bhagavatam, the first stratum of the covering (earth) is calculated to extend eighty million miles, and the subsequent coverings of the universe are respectively of fire, effulgence, air and ether, one after another, each extending ten times further than the previous.

</td> <td class="content" colspan="2" valign="top"> The atmospheric Cherenkov gamma- ray telescope MAGIC, designed for a low- energy threshold, has detected very- high- energy gamma rays from a giant flare of the distant Quasi- Stellar Radio Source ( in short: radio quasar) 3C 279, at a distance of more than 5 billion light- years ( a redshift of 0.536). No quasar has been observed previously in very- high- energy gamma radiation, and this is also the most distant object detected emitting gamma rays above 50 gigaelectron volts. Because high- energy gamma rays may be stopped by interacting with the diffuse background light in the universe, the observations by MAGIC imply a low amount for such light, consistent with that known from galaxy counts. </td> </tr> <tr><td colspan="3">

What are the opinion of other Physicists like Stephen Hawking, etc?
