DNA may help scientists find ‘dark matter,’ the glue that binds galaxies

That wonder molecule of life on Earth, DNA, is now being enlisted in the search for an exotic species zooming through the cosmos: dark matter... As far back as the 1930s, astronomers watching distant galaxies saw that something was missing: There were not enough stars to account for the heavy gravity needed to whirl galaxies so quickly or smash them together so swiftly.

 

The holy grail of physics

Imagine that the visible universe and everything in it was once contained in a volume many times smaller than the size of a single atom. With a quantum theory of gravity, we may be able to trace the Big Bang expansion back to its very beginning, and understand precisely how our universe arose, presumably from nothing.

 

Scientists say they're closing in on elusive Higgs boson

Higgs Boson

Physicists investigating the make-up of the universe said on Wednesday they were closing in on the long-sought but elusive Higgs boson they believe was key to turning debris from the Big Bang into stars, planets and finally life.

 

Dark matter theory 'may be wrong'

Scientists’ predictions of the formation and characteristics of dark matter are shaken by research into dwarf galaxies surrounding the Milky Way.

 

Antimatter Belt Detected Orbiting the Earth

The PAMELA satellite has discovered that there's an antiproton belt present in the Earth's magnetosphere.

 

Cosmic Log: Hidden universes revealed

Science editor Alan Boyle's Weblog: Is it preposterous to consider the existence of parallel universes? Or is it preposterous not to? Physicist Brian Greene would tend toward the latter view.

 

Physicists replicate a supernova in laboratory

Physicists replicate a supernova in laboratory

This composite image of the Tycho supernova remnant combines infrared and X-ray observations obtained with NASA's Spitzer and Chandra space observatories, respectively, and the Calar Alto observatory, Spain. It shows the scene more than four centuries after the brilliant star explosion witnessed by Tycho Brahe and other astronomers of that era.

 

Dark energy flattens the Universe

Researchers have developed a simple geometrical method to add weight to the idea that ours is a flat, dark-energy-rich Universe.
