Buracos negros - Pessoal, vejam esta:

"Black hole-like phenomena created by collider"

A" fireball created in a particle accelerator bears a striking similarity to a black hole. But do not panic: even if the controversial claim is true, it is not the sort of black hole that would cause Earth to disappear in a puff of radiation.

At the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in Upton, New York, US, beams of gold nuclei travelling at close to the speed of light are smashed into each other. The intense heat of the collision breaks down the nuclei into quarks and gluons, the most basic building blocks of all normal matter. These particles form a ball of plasma about 300 million times hotter than the surface of the sun (New Scientist print edition, 16 October 2004)."

Um dia destes, acordámos de manhã, estámos mesmo a sair de casa e... surge uma luz e puf, toda a terra se vaporiza!
Ou então daqui a uns tempos, teremos energia gratuita (isto se os interesses económicos não bloquearem isso)
