Vacuum catastrophe

In cosmology the vacuum catastrophe refers to the disagreement of 107 orders of magnitude between the upper bound upon the vacuum energy density as inferred from data obtained from the Voyager spacecraft of less than 1014 GeV/m3 and the zero-point energy of 10121 GeV/m3 calculated using quantum field theory.[1] This discrepancy has been termed "the worst theoretical prediction in the history of physics!"[2]

This problem was identified at an early stage by Walther Nernst,[3] who raised the question of the consequences of such a huge energy of vacuum on gravitational effects.[4] A recent philosophical and historical assessment is provided by Rugh and Zinkernagel.[5]
