The most comprehensive assessment of the energy output in the nearby universe reveals that today's produced energy is only about half of what it was 2 billion years ago. A team of international scientists used several of the world's most powerful telescopes to study the energy of the universe and concluded that the universe is slowly dying.
"We used as many space- and ground-based telescopes as we could get our hands on to measure the energy output of over 200,000 galaxies across as broad a wavelength range as possible," Galaxy And Mass Assembly (GAMA) team leader Simon Driver, of the University of Western Australia, said in a statement. The astronomers created a video explaining the slow death of the universe to illustrate the discovery.

Matter is converted to energy all the time.

E=mc^2, not E ~ mc^2. Which means matter is not just somehow equivalent to energy, but actually is energy, and vice versa. This goes so far that a mechanic wrist-watch, after it's wound up (and therefore, as a system, contains more energy) gains m=e/(c^2) mass. There is no gain of energy by converting mass to energy, this is just a conversion of one form of energy to another form of energy.
What I don't know/understand at all is how this works on quantum level (Quantum fluctuation [wikipedia.org])
