Those who enjoy the splendor of a starlight night would certainly agree that the heavens seem dark.
But it was only recently that scientists knew exactly how dark.
"About 96 percent of the universe is composed of dark matter and dark energy," said Mike Guidry, professor of nuclear astrophysics at the University of Tennessee's Department of Physics and Astronomy.
"The ordinary matter that we can detect composes only 4 percent of the observable universe."
Guidry is skeptical of a new scientific claim that current cosmological models could be way off - and that dark energy and dark matter might not dominate the universe after all.

"I agree with the UT professor, dark energy and dark matter are now facts. The standard cosmology theory is adequate once it's realized that dark energy comes from a predominance of anti-gravitating w = -1 virtual bosons inside the vacuum and dark matter comes from a predominance of gravitating w = -1 virtual fermion loops inside the vacuum on long and short scales respectively. The latter is mistaken for real particles on mass shell (quantum field theory) with w = 0 (CDM). Einstein's 1916 GR and basic quantum uncertainty - all mainstream - suffice to explain the data in my opinion - at least qualitatively."
