Universe is Slowly (But Very Slowly) Dying



By Nola Taylor Redd and Space.com

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.

When the Big Bang created the energy of the universe about 13.8 billion years ago, some portion of that energy found itself locked up as mass. When stars shine, they are converting that mass back into energy, as described by Albert Einstein's famous equation E = mc2 (energy = mass x speed of light squared).

"This new energy is either absorbed by dust as it travels through the host galaxy, or escapes into intergalactic space and travels until it hits something, such as another star, a planet, or, very occasionally, a telescope mirror."
