Stephen Hawking, who has died aged
76, wanted the formula that measures the energy released by
black holes on his tombstone, longtime collaborator Remo Ruffini
told ANSA Wednesday.
Ruffini, head of the International Centre for the Relativity
Astrophysics Network (IcraNet) and president of the
INternational Relativity Astrophysics International Center
(Icra), worked out the formula with Hawking and mathematician
Roy Kerr.
The energy released by black hols when they are formed is a
sort of moan by these cosmic giants.
