Dark Energy

A very exciting subject for those who it interests to him to investigate mainly what the universe locks up. It is indicated that the dark energy is the cosmological constant of Einstein, or, in other words, that " the nothing weighs algo" " , it affirms Alexey Vikhlinin, of the Smithsonian Astrophysical Observatory (Cambridge, EE.UU.), that has directed the study. The dark energy would be the energy of the emptiness, that the physicists like to visualize like a very slight particle field in an unstable state, basically a remainder of the state of the right universe after Big Bang. If they are in the certain thing, when all these particles become matter, within some thousands of million years, the universal one finally will stop accelerating.

it remembers, that the dark energy was discovered by two teams of Astronomers, working in Australia and the USA, doing searches to us of distant superNovas to determine the range (can on the basis of the observation of one supernovates to know the distance to which one is. A type of superNova determined that it is the S1a that they have a very precise mechanism by which explodes and causes that always they operate with the same brightness " real" (its absolute magnitude), this causes that they are possible to be taken like distance source, and by all means, if the distance to the superNova I will know the distance to the galaxy contains that it.) Certain, that it exceeds Wikipedia contributes, that in physical cosmology, the dark energy is a hypothetical form of matter or energy that would be present in all the space, producing a negative pressure to us and that tends to increase the acceleration of the expansion of the Universe being in repulsive a gravitational force. To assume the existence of the dark energy is the most frequent way to explain the recent observations of which the Universe seems to be expanding with positive acceleration.
