In the dark - What is the universe made of?

In ancient times, listing the ingredients of the universe was simple: earth, air, fire and water. Today, scientists know that naming all of that, plus everything else familiar in everyday life, leaves out 95 percent of the cosmos’s contents.
From the atoms that make up an astronomer, to the glass and steel of a telescope, to the hot plasma of the stars above — all ordinary stuff accounts for less than 5 percent of the mass and energy in the universe. “All the visible world that we see around us is just the tip of the iceberg,” says Joshua Frieman, an astrophysicist at the University of Chicago and the Fermi National Accelerator Laboratory in Batavia, Ill.
The rest is, quite literally, dark. Nearly one-quarter of the universe’s
composition is as-yet-unidentified material called dark matter. The
remaining 70 percent or so is a mysterious entity — known as dark energy
— that pervades all of space, pushing it apart at an ever-faster rate...

(User Info | Send a Message) | Tom Bearden, John Bedini, and others have shown that this "dark energy" is infact the quantum aether, the virtual particle flux, the negative electron sea that Paul Dirac discovered. Nikola Tesla called it "Radiant Energy" and it goes by different terms. This stuff can be manipulated and converted into usable energy for people.

Engineering student cracks major riddle of the universe (Score: 1)

An engineering undergraduate in Australia has made a major step
forward in solving one of the greatest riddles of the universe: that is,
where most of it is.
Boffins know from observing the universe that it must have a certain
amount of mass, otherwise it would have failed to hold itself together
as well as it has. Argument continues as to just how well it has or is
doing so, but in general astrophysicists are agreed that all the mass we
can see – observed galaxies of stars, dust, gas etc – is not enough to
account for what's going on. There must be a whole lot more mass out
there in some form or another.... More: http://www.theregister.co.uk/2011/05/24/oz_undergrad_finds_the_missing_matter/ [www.theregister.co.uk]

Nobelist Frank Wilczek has characterized the situation as follows. “We
do not understand the disparity. In my opinion, it is the biggest and
most profound gap in our current understanding of the physical world…” ... Wilczek correctly and prophetically stated: “[The solution to the VED
problem] might require inventing entirely new ideas, and abandoning old
ones we thought to be well-established.” ...

NASA Announces Results of Epic Space-Time Experiment (Score: 1)

(User Info | Send a Message) http://www.zpenergy.com |  May 4, 2011: Einstein was right again. There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein's theory of gravity.
Researchers confirmed these points at a press conference today at NASA headquarters where they announced the long-awaited results of Gravity Probe B (GP-B).
"The space-time around Earth appears to be distorted just as general relativity predicts," says Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission. ..

Maybe black holes don't really exist (Score: 1)

Ordinary matter will be converted into vacuum energy when it is
compacted to the point where general relativity predicts that an event
horizon would begin to form. In contrast with ordinary mass-energy,
vacuum energy is gravitationally repulsive, so it would act to stop the
collapse and stabilize the object. At the surface of such objects, there
is a transition layer between the large vacuum energy of the interior
and the very small cosmological vacuum energy. In 2000 my colleagues and
I suggested that this transition layer represents a continuous quantum
phase transition of the vacuum. In 2003 George Musser wrote in
Scientific American about the concept and suggested the name "crystal stars" [www.scientificamerican.com]. But I prefer the name "dark energy stars"....
