FIVU: Science questions as esseys: THE COLOR OF THE SHADOW HOLE
I insist that the questions have a full structure and are good science questions for any consultation that more and more anxiuos entities rush with ( some as sadists). These here are esseys only. Good enough here. after NYT: "This stifling of growth, Dr. Vikhlinin said, is the “unmistakable signature” of an antigravitational force that astronomers have labeled dark energy. It was discovered 10 years ago by astronomers who were using exploding stars called supernovas as distance markers to chart the expansion of the universe. They found that instead of slowing down because of cosmic gravity, as common sense would suggest, the expansion of the universe was actually speeding up, with galaxies zooming apart faster and faster. Dr. Vikhlinin’s results dovetail eerily with the supernova results. Clusters grow by gravity, according to cosmological theory, starting as small dimples in the heat and fizz of the Big Bang and then drawing in surrounding material over the eons. Dark energy would work against gravity and try to push the matter falling in back out, stalling growth. Together with earlier observations, Dr. Vikhlinin said, the new data strengthen the suspicion — but do not prove — that dark energy is a weird antigravity called the cosmological constant that was hypothesized and then abandoned by Albert Einstein as a “blunder” almost a century ago. If that is true, the universe is fated to empty itself out eventually, and all but the Milky Way’s closest neighbors will eventually be out of sight. Other astronomers hailed the work as a new avenue in the investigation of what is happening and will happen to the cosmos. “To date, only one technique — supernovae — has detected dark energy without folding in other observations,” said Michael Turner of the University of Chicago. The fact that two different methods have given similar results for dark energy is a triumph of Einstein’s general theory of relativity, the last word on gravity for the last century, astronomers said. “This was a test that general relativity could have failed,” said William Forman of Harvard, a member of Dr. Vikhlinin’s team. " THE BRIEF SUMMARY OF THE MAJOR ARGUMENTS ABOUT FLOW OF THE HOLE - MORE WILL INEVITABLY COME OUT OR IN ( I have challenged Columbia journalists; taht uis besides our morning filed works) THE ENTHUSIASTS OF THE DARK ARE MARCHING TODAY AND REPOFRT MORE PERFECT PITCH. ( ONLY ONE IS BUSHKLAND REPORT ON AND BEYOND SOLAR SYSTEM) WHERE IS THAT? |
