Astronomers confirm that universe is slowly dying after studying nearly 200,000 galaxies. Energy produced by the galaxies is merely half what it was two billion years ago - and disappearing gradually, according to the outcomes of a study using seven of the world's most powerful telescopes. Astronomer have confirmed this and they say that it is happening across all light wavelengths from the ultraviolet to the infrared. Professor Simon Driver, from the International Centre for Radio Astronomy Research (ICRAR) in Western Australia, who was also leading this study, said 'The universe is fated to decline from here on in, like an old age that lasts forever,' said 'The universe has basically plonked itself down on the sofa, pulled up a blanket and is about to nod off for an eternal doze.' The Galaxy And Mass Assembly (GAMA) study, released on last Monday, is the biggest multi-wavelength research to date.
Scientists collated data from the world’s most powerful telescopes, counting the VIST and the VST at Chile’s Paranal Observatory, WISE , Nasa’s GALEX and a European Space Agency Herschel telescope. In an extraordinary collection of data, they intended to map and model all of the energy produced in the universe today. Astronomers will now look into mapping the history of the universe's energy. All the energy in the cosmos was generated in the Big Bang that created the cosmos, with some of it locked up as mass. Stars shine by transforming their mass into energy, as defined by Albert Einstein's famous equation E=MC squared.
Nonetheless, this energy-making procedure is gradually fading. Professor Driver said: 'While maximum of the energy splattering around was produced in the result of the Big Bang, additional energy is continuously being released by stars as they fuse elements like hydrogen and helium together. This newly unconfined 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, planet, or very occasionally a telescope mirror.'
The fact that the universe is gradually fading has been acknowledged since the late 1990s but the new study is the most precise and productive study to date.
Professor Driver presented the results at the International Astronomical Union's general meeting in Honolulu, Hawaii.
