THE EPIC OF GILGAMESH

I WILL proclaim to the world the deeds of Gilgamesh. This was the man to whom all things were known; thiswas the king who knew the countries of the world. He was wise, he saw mysteries and knew secret things, he brought us a tale of the days before the flood. He went on a long journey, was weary, worn-out with labour,returning he rested, he engraved on a stone the whole story.

When the gods created Gilgamesh they gave him a perfect body. Shamash the glorious sun endowed him with beauty, Adad the god of the storm endowed him with courage, the great gods made his beauty perfect, surpassing allothers, terrifying like a great wild bull. Two thirds they made him god and one third man.

Ciocnirile găurilor negre şi spaţiu-timpul

Au atras uriaşele găuri negre primele galaxii împreună sau au acestea au apărut în interiorul acestor galaxii? E un mister ce durează de mult timp. O nouă analiză a undelor gravitaţionale generate de coliziunea găurilor negre ar putea dezvălui răspunsul.

Majoritatea marilor galaxii pe care le vedem au găuri negre supermasive în centrele lor. Atunci când aceste galaxii se ciocnesc, găurile negre fuzionează într-una singură mai mare şi mai masivă, conform teoriei. Cu toate acestea, observaţiile găurii negre finale nu au adus nici o informaţie despre găurile negre originale.

The return of folklore

Why are gnomes and trolls suddenly back in the limelight?

“History becomes legend, legend becomes myth,” said Galadriel in the film version of The Lord of the Rings from 2001.

And during that first decade in the new millennium, the interest in fantasy, legends and myths exploded in the western world. Harry Potter, The Lord of the Rings, True Blood, and most recently Game of Thrones, are all largely based on old folklore. Surprisingly much of it includes elements from our own Norse mythology and Scandinavian folklore.

Găurile negre şi „bosenova” axionilor

Nori de axioni, particule încă nedescoperite, dar care ar putea exista în număr copios în Univers, s-ar forma şi ar suferi un colaps gravitaţional, eveniment numit „bosenovă”, în apropierea găurilor negre, generând unde gravitaţionale intense.

Găurile negre ar putea concura cu succes cu acceleratoarele de particule în studiul compoziţiei Universului.
