A team of international scientists studying space using the Hubble Telescope found a supernova explosion appeared multiple times in different places due to the impact of gravitation on light ::::
Team member Brad Tucker from the Australian National University in Canberra said a cluster of galaxies and dark matter in front of the explosion had warped the way it looked.
“So if you actually look at how the light has changed over time in each of those four images, it is exactly the same origin, so it has to be the same event,” Dr Tucker said. “The lead author Dr Patrick Kelly (of California) was actually looking through a set of images for an entirely different purpose and thought, ‘this looks a little funny’, and then consulted the rest of us.
“And we thought that it could be something that researchers have been looking for because [Albert] Einstein had predicted this impact on light and astronomers had spent decades trying to find something like this.”
Dr Tucker said the four images of the same event would allow scientists to probe how much mysterious dark matter there was in the universe.
“Dark matter is not uniform, it isn’t nicely spread across the universe,” Dr Tucker said. “There’s clumpy bits in some areas and none in other spots, so this allows us to look closely at the structure of dark matter.”
He said the set of four explosion images would probably appear even more times, and may be witnessed in another part of the sky in the next year or so.
“This delay is actually due to the shape and size of the universe, and the best way to think of it is a bunch of trains which all leave at the same time but take different routes, around mountains and so on, so they will arrive at different times,” Dr Tucker said.
The research has been published in Science journal as part of the celebrations to mark 100 years since Einstein’s General Theory of Relativity was released.
RELATED! Albert Einstein Nazi Letters For Sale
In one of the letters, the father of relativity praises the Friends of Truth, a Cincinnati-based German-American group, for not allowing Jews to join it because it would weaken their anti-Nazi message.
“You’re absolutely right not to accept Jews in your ranks, as it would weaken your position. For similar reasons, I have so far avoided speaking out openly about this issue,” Einstein said.
Einstein made his home in the United States after Adolf Hitler came to power in 1933. “I welcome your association and their work from the bottom of my heart,” Einstein wrote in an August 1934 letter to group member August Hamelberg :: Read the full article »»»»
RELATED! Standard Model of Physics Confirmed By CERN, ooops…
However, this week scientists from the European Organization for Nuclear Research – CERN – released brand new findings on data first collected almost two years ago.
The biggest discovery, the particle that scientists watched decay into fermions – the quantum particles associated with matter – was indeed the Higgs boson, nailing once and for all the SM – Standard Model of Particle Physics – as the most likely to be rightest “theory of almost everything” maybe.
The discovery of the Higgs boson might seem like cause for celebration – and it was – but as the discovery settles itself into science, physicists are left slightly deflated.
The confirmation of the existance of the Higgs boson completes the SM – and what’s wrong with that I hear you ask – the Standard Model of Particle Physics in it’s current, finalised form, doesn’t explain a bunch of stuff like gravity, the universes accelerating expansion or the other 25% of the universe made up of Dark Matter :: Read the full article »»»»
RELATED! Loose Cable Behind CERN Faster-than-light Result
The controversial finding that cast a large shadow of doubt over Einstein’s belief that nothing can travel faster than the speed of light might have been caused by a loose cable, the lab behind the result said. Physicists at the CERN laboratory near Geneva appeared to contradict Albert Einstein last year when they reported that sub-atomic particles called neutrinos could travel fractions of a second faster than light. Einstein had said nothing could travel faster than light.
James Gillies, a spokesman for CERN, said the lab’s startling result was now in doubt. Earlier on Wednesday, the website ScienceInsider reported the surprising result was down to a loose fibre optic cable linking a Global Positioning System satellite receiver to a computer. ScienceInsider is run by the respected American Association for the Advancement of Science. Mr Gillies confirmed a flaw in the GPS system was now suspected as a possible cause for the surprising reading. Gillies’ says further testing was needed before any definite conclusions could be reached :: Read the full article »»»»

What’s the worst possible thing that could happen in 2012? It just depends who’s boat your sitting on. For Doomsayers, 2012 is The Apocolypse, The End of Days – much like Harold Camping’s Rapture, May 21, 2011 and October 21, 2011 – For those of us still sat here asking wtf are you dribbling on about?
That überpopular Princeton wiz Michio Kaku – you’ll know who he is when you see the video – dispells a bundle of crackpot prophetic theories via his Big Think session.
The 2012 doomsday prophecies are many and varied, principally comprising of a range of eschatological beliefs according to which cataclysmic events will occur on December 21, 2012. This date is regarded as the end-date of a 5,125-year-long cycle in the Mesoamerican Long Count calendar, and the crackpots swear by it!
Various astronomical alignments and numerological formulae have been proposed as pertaining to this date, though none have been accepted by mainstream scholars, most likely due to the fact that since man began to look up and count at the same time he’s been predicting some form of galactic doom :: Read the full article »»»»
RELATED! Astronomers Discover Largest Black Holes EVER!?
Scientists have discovered the two biggest black holes ever observed, each with a mass billions of times greater than the Sun’s, according to a study published overnight. The two giants are located in the heart of a pair of galaxies several hundred million light years from Earth, the study was published in the scientific journal Nature.
Each black hole is estimated to have a mass about 10 billion times greater than the sun, dwarfing the previously largest-known black hole, which has a mass of 6.3 billion suns.
The University of California, Berkeley, team led by Nicholas McConnell and Chung-Pei Ma said one black hole is located in NGC 3842, the brightest of a cluster of galaxies about 320 million light years from Earth. The second hole is of “comparable or greater mass” and is located in NGC 4889, the brightest galaxy in the Coma cluster, about 335 million light years away.
“These two black holes are significantly more massive than predicted,” the astronomers wrote.
The researchers said their calculations suggest that different evolutionary processes influence the growth of the largest galaxies and their black holes than in smaller galaxies. Astronomers have long supposed that since the universe began it has harboured black holes with a mass the size of the two newly found giants. These cosmic gluttons grow in tandem with their galaxies, slurping up gases, planets and stars :: Read the full article »»»»
