“Not only does God play dice but… he sometimes throws them where they cannot be seen,” said Stephen Hawking about the paradoxical physics of black Holes. Welcome to the bizarre quantum world of “strange metals” –a new state of matter.
Share Remarkable Properties with Black Holes
“The fact that we call them strange metals should tell you how well we understand them. Strange metals share remarkable properties with black holes, opening exciting new directions for theoretical physics,” says Olivier Parcollet, a senior research scientist at the Flatiron Institute’s Center for Computational Quantum Physics (CCQ), about the quantum world of metals that dissipate energy as fast as they’re allowed to under the laws of quantum mechanics. The electrical resistivity of a strange metal, unlike that of ordinary metals, is proportional to the temperature.
In 2013, the Hubble Space Telescope found the birth certificate of oldest known star in the universe, cataloged as HD 140283, aptly named “methuselah”. The star, located in the constellation Libra, which is at the very first stages of expanding into a red giant, could be as old as 14.5 billion years (plus or minus 0.8 billion years), which at first glance would make it older than the universe’s calculated age of about 13.8 billion years, creating what we commonly call a dilemma.
The strange star, said NASA’s Hubble team, which has an anemic 1/250th as much of the heavy element content of our sun and other stars in our solar neighborhood.)has been known about for more than a century because of its fast motion across the sky. The high rate of motion is evidence that the star is simply a visitor to our stellar neighborhood. Its orbit carries it down through the plane of our galaxy from the ancient halo of stars that encircle the Milky Way, and will eventually slingshot back
Cell-spanning whirlpools in the immature egg cells of animals such as mice, zebrafish and fruit flies quickly mix the cells innards, but scientists didn t know how these flows form. Using mathematical modeling, researchers have found an answer. The gyres result from the collective behavior of rodlike molecular tubes called microtubules that extend inward from the cells membranes, the researchers report.

New work agrees with older research suggesting the oldest light in the universe – from the most distant galaxy yet known – started its journey toward us 13.77 billion years ago.
View larger. | In 2013, the Planck space telescope released the most detailed map to date of the cosmic microwave background, the relic radiation from the Big Bang. It was the mission’s first all-sky picture of the oldest light in our universe, imprinted on the sky when it was just 380,000 years old. Now a new, independent study agrees with Planck’s results. That’s good news for astronomers trying to pin down the universe’s age and rate of expansion. Image via ESA.
