Fate of Universe revealed by galactic lens
By Howard Falcon-Lang
The huge galactic cluster known as Abell 1689 acted as a cosmic magnifying glass. A “galactic lens” has revealed that the Universe will probably expand forever.
Astronomers used the way that light from distant stars was distorted by a huge galactic cluster known as Abell 1689 to work out the amount of dark energy in the cosmos.
Understanding the distribution of this force revealed that the likely fate of the Universe was to keep on expanding.
It will eventually become a cold, dead wasteland, researchers say.
The study, conducted by an international team led by Professor Eric Jullo of Nasa’s Jet Propulsion Laboratory in California, is published in the journal Science.
Dark energy makes up three-quarters of our Universe but is totally invisible. We only know it exists because of its effect on the expansion of the Universe.
To work out how dark energy is spread through space, astronomers used the Hubble Space Telescope to observe the way that light from distant stars was distorted around Abell 1689, a nearby cluster of galaxies.
Abell 1689, found in the constellation of Virgo, is one of the biggest galactic clusters known to science.
Light bends around massive galaxy clusters, allowing distant objects to be seen
Because of its huge mass, the cluster acts as a cosmic magnifying glass, causing light to bend around it.
The way in which light is distorted by this cosmic lens depends on three factors: how far away the distant object is; the mass of Abell 1689; and the distribution of dark energy.
The astronomers were able to measure the first two variables using the European Southern Observatory’s Very Large Telescope, enabling them to calculate this crucial third factor.
Knowing the distribution of dark energy tells astronomers that the Universe will continue to get bigger indefinitely.
Eventually it will become a cold, dead wasteland with a temperature approaching what scientists term “absolute zero”.
My take on the above:
I am shivering already! (not)

LOL, At least the fate of the Universe until Vishnu stops exhaling and starts inhaling. :-)
Jagad-anda-nathah means… Jagad-anda means universe. In each universe there is a natha, or the supervisor, or the manager, or the supreme person. Just like for management we are. Similarly, in each universe there is Lord Brahma. He is the supreme creature, manager. So these managers live only to that period when Maha-Visnu exhales. When the nisvasita-kalam. Just like we exhale and inhale, so… But exhaling the all these universes are created, and at His inhale they go into the Maha-Visnu, in the… The coming and going.

Oooh! So mysterious! Although Europeans often misinterpreted the Lakota word “Wakan Tanka” as “Great Spirit” it is more properly translated as “Great Mystery”.
“O supreme great one! O Supreme Personality of Godhead! O Supersoul, master of all mystic power! Your pastimes are taking place continuously in these three worlds, but who can estimate where, how and when You are employing Your spiritual energy and performing these innumerable pastimes? No one can understand the mystery of how Your spiritual energy acts.”
