Audacious cosmology

Expansion of universe is measured



For the past month humans from nearly every major country using all the leading edge technology available to mankind to find a plane that is equipped with all the leading edge technology haven't been able to triangulate its whereabouts right here on good old planet earth. But cosmologist have triangulate something that "theoretically" happened 13 billion years in the past from galaxies that are multiple millions of light years away, so far away in fact that even the gods have a difficult time traveling such distances. Too bad that someone already bought the Brooklyn Bridge, because if anyone believes any of the stuff that's been coming out of cosmology lately, they would make great candidates for buying the Brooklyn Bridge. Or, perhaps they should recruit cosmologist in their search for the missing jet. Heck, them cosmologist people have been on a pulitzer prize searching frenzy the last few years. And for what? They haven't discovered anything.

Btw, everything in the universe has a spin, meaning things go round and round, kind of like a dog chasing its tail. Galaxies do move, in circles. The universe is not expanding and it will never contract. My "theory" is just as good as anyone else's, except I don't have the big fancy doohickies to play with...nor a snowball's chance in hell of snagging a Pulitzer. They don't give Pulitzers to UFO nuts...not fair.

Astronomers say they have made the best measurement yet of how fast the universe is expanding during the 13 billion years since its formation.
They have discovered that 10.8 billion years ago the universe was expanding by 1% every 44 million years.

The team from the Sloan Digital Sky Survey (SDSS) combined two different methods of using quasars and intergalactic hydrogen gas to measure the rate of expansion of the universe.
They looked at 140,000 distant quasars, luminous regions in the centre of massive galaxies, when the universe was only one quarter of its present age.
The position of the gas clouds are mapped in three dimensions, and at different distances the gas blocks showed different-coloured light from the quasars.
Dr Matthew Pieri, from the Institute of Cosmology and Gravitation at the University of Portsmouth, said: "We are measuring the expansion of the universe with exquisite detail. Like the rings of a tree trunk, each quasar spectrum becomes an archive of the universe's history."
