Scientists Take Most Accurate Reading Yet of Universe's Cooling

Posted by samzenpus on Wednesday January 23, 2013 @12:15PM from the you-feel-a-little-warm dept.

angry tapir writes "An international team of astronomers has used the CSIRO-run Australia Telescope Compact Array to measure the cooling of the universe since the Big Bang. According to the CSIRO, it is the most accurate reading yet of how hot the universe used to be. When the universe was half its current age its temperature was -267.92 degrees Celsius (5.08 Kelvin), the team found, which is warmer than today's universe (-270.27 degrees Celsius)."

267.92C is 5.23 K, not 5.08 K, and 270.27C is freaking hot.

  parenthesis around a number almost always indicate a negative number
  So from the summary:
  
  (5.08 Kelvin)
  would be negative Kelvin? OK.

  Just make it 640K, that should be enough for any universe.

Yeah, they knew about the universe before it was cool.

  Actually, according to the poster, it's heated up by a considerable margin. "Which is warmer than today's universe (270.27 degrees Celsius)." I'd like to buy a math transform, an inverse abs() function please?

Yeah, heat death is most probably how the world will end, unless some radical new insight is thought up.

Re:Sure the universe is cool, but so are black hol by Genda · 2013-01-23 13:49 · Score: 2

In fact since due to time dilation, everything that drops into a blackhole seems to freeze at the event horizon, the energy radiating from the black hole must equal the energy that will be lost as a function of the matter that falls in.

Don't worry, although that fate is inevitable there's no chance you will be there to see it. Besides, it's only 0.5 billion years until the oceans evaporate and Earth resembles Venus.
