Absolute Zero in Space


Question:  Can there be absolute zero in outer space?
jacqueline tostades

Answer:  Not really.  Even "empty" space is filled with cosmic background
radiation left over from the Big Bang.  Recent measurements from
the COBE satellite have mapped this radiation very precisely and
give its average value as 2.73 deg Kelvin, or 2.73 degrees above
Absolute Zero.
