----------------------------------- Teo 01 Oct 2015 13:42 ----------------------------------- Da. Aveti dreptate. Cu toate acestea, termenul "dark energy" exista. De ce au ales sa ii spuna energie neagra (intunecata), asta nu mai stiu. Probabil pentru ca actioneaza dar nu poate fi evidentiata in mod direct, decat (indirect) prin accelerarea expansiunii universului vizibil. Iata ce spune NASA : http://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy/ "Eventually theorists came up with three sorts of explanations. Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration. Theorists still don't know what the correct explanation is, but they have given the solution a name. It is called dark energy." si Wikipedia : https://en.wikipedia.org/wiki/Dark_energy
