The forces of rotation caused red hot masses of stones to be torn away from the Earth and to be thrown into the ether, and this is the origin of the stars.

As­tro­no­mers have used com­put­er sim­ula­t­ions to cal­cu­late that a black hole at the heart of one the larg­est near­by ga­lax­ies is two to three times heav­i­er than pre­vi­ously thought.

Weigh­ing the equiv­a­lent of about 6.4 bil­lion Suns, the black hole in gal­axy M87 is the most mas­sive yet meas­ured with a re­li­a­ble tech­nique, and sug­gests that the ac­cept­ed black hole mass­es in near­by large ga­lax­ies may be off by si­m­i­lar amounts, ac­cord­ing to re­search­ers.
