General Overturning Einstein
2012.02.20 10:09
 Overturning Einstein Physcist Julian Barbour is rewriting Albert Einstein's rules of space, time and gravity. Einstein's space and time fabric left a few loose threads that cosmologists have struggled to tie up. General relativity alone cannot explain the observed motions of galaxies or the way the universe seems to expand. If Einstein's model of gravity is correct, around 96% of the cosmos appears to be missing, which led to as yet unidentified dark matter and dark energy. Einstein's relativity theory also failed to reconcile with quantum mechanics. Einstein got the idea of space and time and relativity from Ernst Mach, Austrian physicist. Long before Einstein, Mach had advocated a "truly relative theory." Barbour studied Mach and realized that Einstein failed to implement Mach ideas in the most direct way because he thought that way was too hard. Barbour felt that Einstein had taken a circuitous route to reframing the cosmos. By 1964 Barbour who was finishing graduate school decided to pick up where Mach had left off in defiance of Einstein. With his father's indirect encouragement, he decided to dedicate the rest of life to this project by working by himself at a farm house at South Newington, England. In 1975 Bruno Bertotti, an Italian physcist joined him. By 1982, these two had come up with a new theory of gravity that described the world just as accurately as Einstein's general relativity but without invoking time as a fundamental dimension. They have radically reformulated Einstein in different light. More young physcists like Sean Gryb and Gomes joined his endeavor. Barbour remains convinced that Einstein didn't go far enough: relativity wasn't truly relative so that fundamental inconsistencies in Einstein's model of the universe remained. Barbour, now 75, has dedicated over 40 years, waiting to be vindicated when so many physcists embrace what to him are clearly illusions about Einstein's space and time. ....

Dr. Lee
I lost the issue you quoted somewhere with the Einstein's portait portrait upside down on the cover.
But I found an earlier issue Dec. 2011, Discover with a short article,
"THE PERILS OF MESSING WITH RELATIVITY".
The issue also says they recently found out the "neutrino" is faster than light.
It seems the equation we learned in most instances are applicable for practical use: making atom bomb, making nuclear reactor, GPS system design etc,
where E is energy, m is mass, and c is the speed of light in a vacuumThen why Einstein chose the light as C.
Answer is simple.
He did not know any other stuff faster than light?
Apparently, using the speed of light, the GPS system design, measuing the cosmic distances, etc. they did not have
much problem, the article says.
Then, to my simple mind, the light speed may not be an ultimate number, fixed speed, as they will find out other
stuff faster than light.Question:
Can the light travel a bit faster or slower than the regular light?I think so. ㅎㅎㅎ
I can run faster than a super-sonic jet for 10 seconds.
How?
If I run inside of the supersonic jet cabin in foward direction, my speed will be
(jet airplane speed + my running speed).If we shoot the light to east,
the Light will travel = (Light speed+ speed of earth moving as meassued on the surface of earth)
If we shoot the light to west, the other way around: light will travel slower, with the speed of light less the speed of earth moving. Of course the speed of earth moving is negligible in comparsion to the speed of light, but it cannot be
ignored.What you thnink?

Thank you for the input, Dr. Minn.
I certainly cannot answer any of your brilliant questions.
You and I hope to hear more new developments in this area of physics.
How little we humans know about our universe in spite of Newton, Einstein, Planck, Bohr and
so many other geniuses in physics.
We ordinary minds depend upon their brains to learn about this universe.
In actuality, scientists are the ones who have advanced human civilizations regardless whether it's good or bad
and have influenced the way humans are thinking and changing everything including arts, philosophy, everything else.
I once read the best seller book, making of atomic bomb, where USA assembled all the brilliant geniuses in physics
and succeeded winning the world war two.
All those scientist didn't think of the politicians very much. They all uniformly seemed to have the attitude that
they are the ones making history, not the politicians. They are fighting the scientists of the ememy side every day.
That was my impression.
When you look at the behind the scenes of all the major wars in human history,
it seems that always scientists have played the major role in the outcome. -

And when all else fails to explain the order of the universe (if there's such thing),
then a scholar (or scientist) turns around and says that the universe is God's creation.
(That's exactly what was quoted by Dr. Lee in one of the previous article in our website.)Since even a country-church pastor with just elementary education, or anyone of us can say that,
should the "distinguished and highly honored" Princeton scientist return the Nobel Prize he won??
I mean... what's the difference between Einstein and the pastor in their scientific knowledge?
One is not any better than the other !! Then what the hell was the Nobel Prize for?What I am trying to say is:
A scientist should stay and be stuck in the arena of scientific study.
He shouldn't be looking for God to answer his questions, or use God to explain his dilemma. -

항상 궁금해온 것은
왜 인간 진화과정에서, supernatural 한데 인간 두뇌가 빨려들어가, 온같 미신, 원시 신앙이,
지구상 모든 인류 머리속에 생기게 됏는지?언제 Time 잡지에, 종교본능은 인간 이 살아 남는테, 유용한 역활을 햇을거라고 합디디.
곤경에 처할때, 전지 전능한 "신" 에다 기도해서,
용기를 가지고 7 전 8 기의 용기를 심어주는게 신앙심 종교적본능이 아닌가 함.제 생각은 종교적인 신앙심은 사람마다 정도가 다르고
날때부터, "세상의 경이로움" 에 항상 의문을 품고 그 질문 계속하다, 어뜬 종교에 빨려들어가지 않는가 하지요.
종교적인 성향은 타고 날때부터 결정이된다니
예수교가 없으면, 무슨 다른 종교든지, 아니면 미신에 홀딱 끌려가게 마련.우리 집안 어른이 6.25 때 배우자를 행방불명으로 잃은 후에는
그렇게 영심히 점쟁이 "인생 철학관" 찾어가는걸 보았는데,
나중에는 모두 교회로 전향. -

GENEVA/CHICAGO (Reuters) - The world of science was upended last year when an experiment appeared to show
one of Einstein's fundamental theories was wrong - but now the lab behind it says the result could have been caused by a loose cable.Physicists at the CERN research institute near Geneva appeared to contradict Albert Einstein's 1905 Special Theory of Relativity last year when they reported that sub-atomic particles called neutrinos could travel fractions of a second faster than light.
Einstein's Special Theory of Relativity, which underpins the current view of how the universe works, says that nothing
can travel faster than light, and doing so would be like traveling back in time.James Gillies, a spokesman for European Organization for Nuclear Research, or CERN, said on Wednesday the lab's
startling result was now in doubt.Earlier on Wednesday, ScienceInsider, a website run by the American Association for the Advancement of Science,
reported that the surprising result was down to a loose fibre optic cable linking a Global Positioning System satellite
receiver to a computer.Gillies confirmed that a flaw in the GPS system was now suspected as a possible cause for the surprising reading.
Further testing was needed before any definite conclusions could be reached, he added.The faster-than-light finding was recorded when 15,000 neutrino beams were pumped over three years from CERN
to an underground Italian laboratory at Gran Sasso near Rome."A possible explanation has been found. But we won't know until we have tested it out with a new beam to Gran
Sasso," Gillies told Reuters in Geneva.Physicists on the experiment, called OPERA, said when they reported it last September that they had checked and
rechecked over many months anything that could have produced a misreading before announcing what they had found.A second test whose results were announced in November appeared to provide further evidence that neutrinos were
travelling faster than light. But many experts remained skeptical of a result that would have overturned one of the
fundamental principles of modern physics.Edward Blucher, chairman of the Department of Physics at the University of Chicago, said the original finding would
have been breathtaking if it had been true. As it was, the research inspired many spirited discussions, if few believers."I don't think I met anyone who said I bet it's going to be true. I think the people on the experiment worked as
carefully as they could and I think they ran out of ideas of what could be wrong and they decided to present it,"
he said."Maybe they should have waited a few more months," he added.
Gillies said CERN would be issuing a full statement early on Thursday.

이선생이 언급하신 실험들 계속하면, 수백년 년 후에는 우주의 신비가 조금 더 벗겨질지 궁금하군요.
지구가 태양주위를 돈다는 사실을 알기 까지 인류가 수백만년을 기라려야 햇고,
옛날 위대한 사람들이라도, 그런 지동설 얘기는 짐작도 못하고 황당무계한 지구인간 창조의 이얘기 만들어 써 논걸을 기독교성경에 집어넣엇는데,
그게 신의 말씀이라고 믿는 사람과 현대교육받은 사람과 대화가 가능할찌 모르겟읍니다.
suicide bombing하면 천국가서 처녀들에게 둘러싸여 행복하게 살게된다는 헛소리에 놀아난 사람이 아직도 이세상 역사를 바꾸어 노려고
야단인 세상에 우리가 살고잇다니 !!
지금도 미국같이 문명한 사회에서, 성경을 쓴대고 믿고
진화론과 법정싸움을 싸음을 하고 있는사람이 많은가 본데,..
Albert Einstein made a mistake by not pursuing Mach's original idea of relativity directly.
As a 30 some year old graduate student, he decided to bet his entire life to prove that
Einstein made a mistake. He convinced himself by studying Ernst Mach's original concept of relativity.
He has produced results to convince a good number of young brilliant physcists, two of whom
were able to receive PHDs on the same subject.
I wrote a brief excerpt myself by reading the entire article, which I thought was a worthwhile news.
This was the cover story of the magazine with Einstein's picture upside down on the cover.
