It cannot come from the Einstein's mass-energy equivalence, considering the low gas temperature within the Bok globules.
The problem of correctly defining the source of the gravitational power heating the Bok globules remained unsolved in absence of a theory of the gravitational interaction able to specify the rate at which the gravitational waves hit the particles.
2] molecules of the Bok globules, quick calculations can be made recognising that Eq.
The observed Bok globules denounced an inner hot core.
4] metres within the observed Bok globules (R = 2 x [10.
