The Price of the Planet

Astrophysicist Greg Laughlin came up with a figure of €3000 trillion ($3,000,000,000,000,000) for the worth of planet Earth, given its breathable atmosphere—a shield from cosmic radiation.

 A close estimate is by Greg Laughlinas as US$5000 trillion.

 By contrast, Mars is estimated as a modest $16,000 while Venus is dismissed at about a penny. 

Far from a joke, such estimates symbolize the religious worship of money and the confirmation that capitalists know the price of everything, but the value of nothing
