All Down Hill From Here On For The Universe: Galaxies Have Entered ‘Old Age and Preparing for Death’
ENERGY levels in galaxies are dipping which is signifying the beginning of the end for the universe, according to experts.
Astronomers believe that the universe has begun its slow process of dying after noticing that energy levels in galaxies are falling.
A wide-spectrum survey of more than 200,000 galaxies has shown that energy levels are falling as a result of the fusion of matter taking place in stars.
Experts state that the levels of energy being generated is not half of what it was two billion years ago.
Researchers from the International Centre for Radio Astronomy Research (ICRAR) in Western Australia used seven powerful telescopes from around the globe to examine galaxies with 21 different light wavelengths – ranging from ultraviolet to far infrared.
Professor Simon Driver of the ICRAR said at a International Astronomical Union’s General Assembly: “We used as many space and ground-based telescopes we could get our hands on, to measure the energy output of over 200,000 galaxies across as broad a wavelength range as possible.
“While most of the energy sloshing around was created in the aftermath of the Big Bang, additional energy is constantly being released by stars as they fuse elements like hydrogen and helium together.
The universe is slowly dying
“This newly released 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 Universe will decline from here on in, sliding gently into old age. The Universe has basically sat down on the sofa, pulled up a blanket and is about to nod off for an eternal doze.”
The universe has only 2 billion years left
Earlier this year, astronomers warned that the universe has just an eighth of its life yet, signalling that it has entered old age.
By analysing data surrounding galaxies, supernovae, and ripples in baryon acoustic oscillations – a form of matter – which are all used to measure the presence of dark energy, a team, led by Diego Sáez-Gómez at the University of Lisbon, Portugal, found that the earliest a big rip in the universe can occur is 1.2 times that of the age of the universe – or 2.8 billion years.
