Sometimes hints come from the Royal Society but billions are billions
and work in the Kingdom of Dark Energy continues:

http://www.telegraph.co.uk/science/6057362/Give-scientists-the-freedom-to-be-wrong.html
Martin Rees: "Over the past week, two stories in the press have
suggested that scientists have been very wrong about some very big
issues. First, a new paper seemed to suggest that dark energy the
mysterious force that makes up three quarters of the universe, and is
pushing the galaxies further apart might not even exist."

I think Einsteinians should take more notice of what the Royal
Society, Einsteiniana's creator, says. A few years ago the Royal
Society said tests on Divine Albert's Divine Theory should stop and
they did stop:

http://www.telegraph.co.uk/science/science-news/3322462/Did-Einstein-get-all-his-sums-right.html
"Did Einstein get all his sums right?.....Last week, an American probe
began an 18-month mission to put Einstein's prediction to the test, 90
years after he unveiled his ideas in Berlin. Gravity Probe B was
blasted into space from the Vandenberg Air Force Base in California on
a Boeing Delta 2 rocket and will orbit the Earth for more than a year.
The $700 million joint mission between Nasa and Stanford University,
conceived in 1958, uses four of the most perfect spheres ever created
inside the world's largest Thermos flask to detect minute distortions
in the fabric of the universe.....Sir Martin Rees, the Astronomer
Royal, said: "The project's a technical triumph, and a triumph of the
persistence and lobbying power of Stanford University. But its
gestation has been grotesquely prolonged, and the cost overruns have
been equally gross. I recall hearing a talk about the project from
Francis Everitt (principal investigator) when I was still a student
and it was already well advanced. "Back in the 1960s the evidence for
Einstein's theory was meagre just two tests, with 10 per cent
precision. But relativity is now confirmed by several tests, with
precision of one part in 10,000. It's still, in principle, good to
have new and different tests. But the level of confidence in
Einstein's theory is now so high that an announcement of the expected
result will 'fork no lightening'. "Moreover, if there's an unexpected
result, I suspect most people will suspect an error in this very
challenging experiment rather than immediately abandon Einstein:
There's now so much evidence corroborating Einstein, that a high
burden of proof is required before he'll be usurped by any rival
theory. "So the most exciting if un-alluring outcome of Gravity Probe
B would be a request by Stanford University for another huge sum of
money to repeat it."

The only reason behind Dark Energy:

"More than a dozen ground-based Dark Energy projects are proposed or
under way, and at least four space-based missions, each of the order
of a billion dollars, are at the design concept stage."

Sometimes the correct solution to the problem is hinted at in
Einsteiniana but then no billions, not even millions, come and
Einsteinians promise not to hint anymore:

"Does the apparently constant speed of light change over the vast
stretches of the universe? Would our understanding of black holes,
ancient supernovae, dark matter, dark energy, the origins of the
universe and its ultimate fate be different if the speed of light were
not constant?.....Couldn't it be that the supposed vacuum of space is
acting as an interstellar medium to lower the speed of light like some
cosmic swimming pool? If so, wouldn't a stick plunged into the pool
appear bent as the light is refracted and won't that affect all our
observations about the universe. I asked theoretical physicist Leonard
Susskind, author of The Black Hole War, recently reviewed in Science
Books to explain this apparent anomaly....."You are entirely right,"
he told me, "there are all sorts of effects on the propagation of
light that astronomers and astrophysicists must account for. The point
of course is that they (not me) do take these effects into account and
correct for them." "In a way this work is very heroic but unheralded,"
adds Susskind, "An immense amount of extremely brilliant analysis has
gone into the detailed corrections that are needed to eliminate these
'spurious' effects so that people like me can just say 'light travels
with the speed of light.' So, there you have it. My concern about
cosmic swimming pools and bent sticks does indeed apply, but
physicists have taken the deviations into account so that other
physicists, such as Susskind, who once proved Stephen Hawking wrong,
can battle their way to a better understanding of the universe."
