Nov 6, 2013 — The hunt for dark matter started in the 1930s and shows no signs of ending any time soon. But physicist Marcelo Gleiser says our inability to pin down this key component to reality only makes it more alluring.
Nov 5, 2013 — We are awash in the unseen, a fact revealed to us by science. But there is more to discover. The hunt for dark matter is still on, says astrophysicist Adam Frank, despite news of another failed attempt to detect the mysterious stuff.
Apr 10, 2013 — Science discovers one dark material after another, making reality stranger than fiction. Commentator Marcelo Gleiser says the recent observation of the Higgs field and last week's announcement of the possible detection of dark matter are just the latest data points in our long quest to know what the Universe is made of.
Apr 25, 2012 — Science hardly ever advances in a straight line. Recent observations casting doubt on the existence of Dark Matter force us to consider the lessons of history.
Apr 21, 2012 — A survey of the sky fails to find signs of Dark Matter, a totally unexpected result. If the observations stand up to scrutiny, our understanding of the universe could shift significantly.
Mar 20, 2012 — It wasn't long ago that we thought expansion of the universe was slowing down. Whoops! Science then identified Dark Energy as a force acting against deceleration. The discovery upended cosmology almost overnight.
Mar 13, 2012 — The things we can see in the universe are moving faster than they should be. Why? Is the answer Dark Matter, or a physics we're not yet aware of? Science has made its choice. Only time will tell if the consensus was correct.
Mar 6, 2012 — Left to its own devices it seems the "dark universe" would never be able to make something as remarkable as life. Now that is something to ponder. Perhaps the dark universe makes us matter more than we ever realized.
Oct 5, 2011 — This years Nobel Prize in physics celebrates what is the biggest mystery in physics today. What's causing the cosmic acceleration?
