Universe ‘resting on sofa’ as it slowly dies

1

SYDNEY: The Universe is experiencing a slow death, like a person resting on the sofa awaiting eternal sleep, according to astronomers from a project which measured the energy generated by 200,000 galaxies.
The international team carried out the most precise measurements of energy generation in a large portion of space ever completed and found that it is only half of what it was two billion years ago and fading.
“The Universe is fated to decline from here on in, like an old age that lasts forever,” said Simon Driver from the International Centre for Radio Astronomy Research (ICRAR) in Western Australia.
“The Universe has basically plonked itself down on the sofa, pulled up a blanket and is about to nod off for an eternal doze.”
Researchers used seven of the world’s most powerful telescopes to observe galaxies at 21 different wavelengths, from ultraviolet to the far infrared, as part of the Galaxy and Mass Assembly Survey (GAMA).
Observations collected over eight years from the Anglo-Australian Telescope in rural New South Wales state were used in conjunction with those from orbiting space telescopes operated by NASA and the European Space Agency.
“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,” said Driver, who is presenting the findings to the International Astronomical Union in Hawaii on Monday.
Driver said while most of the energy sloshing around in the Universe was created in the aftermath of the Big Bang, additional amounts were constantly being released by stars as they fused elements such as hydrogen and helium together.
“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,” he said.
Andrew Hopkins, from the Australian Astronomical Observatory, said while it had been known for some time that the rate at which the Universe was forming stars was declining, the new data showed that the rate of energy production was reducing the same way across all different wavelengths.
“It doesn’t matter which wavelength you look at the Universe in, it is slowing down in its energy production in the same way,” Hopkins told AFP via telephone from Hawaii.
“As the Universe expands and as the rate of expansion accelerates we know that the rate at which galaxies can continue to evolve is going to slow down and this is reflected in the rate that we have been able to measure of how fast they are forming their stars.”
It is hoped that the survey data will help scientists better understand how different types of galaxies form.
Researchers also want to expand their work to map energy production over the entire history of the Universe using new facilities, including the world’s largest radio telescope, the Square Kilometre Array, which is set to be built in Australia and South Africa over the next decade.

  1. Esoptrics (from the Greek for mirror): The Logic Of The Mirror & key to a strictly algebraic model of the Universe = the only cosmological theory ever to explain (and in much detail and algebraic precision to boot) how even space itself as well as its occupants are ultimately (@ c. 10^-47 cm.) a collection of non-spatial points outside of one another, not in any kind of physically spatial medium, but solely in a logically septuplex framework of real relations. Esoptrics PROPOSES the Universe is by no means dying. Currently, it’s carrying out the results of a NINTH big bang destined to last for what we would call roughly 18 trillion Earth years at the end of which a TENTH big bang will result as God, in a tiny fraction of what we’d call a second, introduces c. 10^466 new ultimate constituents first in sets of 8 for 2^511 steps (1 per c. 10^-96 sec. by our reckoning) then sets of 8^2 for 2^510 steps then 8^3 for 2^509 steps, then 8^4 for 2^508 steps, etc.. Each ultimate constituent is a macro-state (called a piggyback form) of COMPOSITE excitation logically concentric with a micro-state (called carrying generator) of COMPOSITE excitation. Each composite state is logically divisible into 6 COMPONENT states currently having some one of 2^256 levels of intensity, and, in each of these composite states, its set of 6 component states have a unique set of real relations to one another which, in turn, give each composite state a unique real relation to each and every one of all the other composite states. Locomotion takes place when the unique set of real relations between a composite state’s 6 component states undergoes a slight change without ceasing to be unique. If not, a logical collision occurs to restore the uniqueness.

    What’s the origin of the 6 component states? In Esoptrics “God” means an infinitely intense tri-functional act on the part of The Supreme Dynamic Mirror’s successful attempt at self-awareness. Since each of these 3 functions has a real relation to each of the other two, the result is an intense state of excitation logically divisible into 6 real relations which then give each created state of excitation its logical divisibility into 6 component states and their unique set of real relations to one another.

    Every macro-state is a balanced one, because, throughout each of its acts, each of its 6 component states has the same one of the 2^256 levels of intensity (cf. Science’s Bosons). Every micro-state is an unbalanced one, because, throughout each of its acts, no component state and its mirrored opposite have the same level of intensity (cf. Science’s Fermions).

    Though a handful of physicists and philosophers have reacted favorably to Esoptrics (though not with enough zeal to evoke from them a significant effort to speak of it to others), the vast majority of the thousands I’ve contacted in 30 years have reacted with indifference. Some, of course, have reacted with gutter level insults and ridicule — especially those sure any cosmological theory bringing God into the picture is, ipso facto, incontrovertible proof its author is etc.. Fortunately, I am so well-off financially, socially (oodles of family & friends), and physiologically (at 79, healthier than most men of 40), no amount of rejection can dispirit me to the slightest extent. Then too, 21 books in print is no small accomplishment no matter how few read them. I guess that’s why my full name as a search string brings up dozens of pages.
