Quantum Gravity – "Casts Doubt On Fate Of Black Holes"

Posted on Dec 21, 2018 “The fate of black holes in a quantum theory of gravity is, in my view, the most important problem in theoretical physics, Said Jorge Pullin, the Horace Hearne professor of theoretical physics at LSU. Black holes created by collapsing stars are mysterious objects with an outer edge called an event horizon, which traps everything including …

Scientists believed Mars was covered in methane. Now it is missing

Just the facts This is what we know: ESA's ExoMars Trace Gas Orbiter (TGO) reached its orbit around March 2016, when it began its mission to monitor and analyze the Red Planet's atmosphere. Although researchers expected TGO's extremely sensitive sensors to pick up atmospheric methane, it has not yet discovered anyone. The orbiter can detect trace amounts of methane concentrations …

Freezing of copper as a precious metal-like catalyst for preliminary hydrogenation

INTRODUCTION The pure utilization of carbon resources for synthesizing high value-added chemicals is highly desirable with the increasing energy and environmental problems 1 ). One of the successful industrial uses is the synthesis of alcohols from carbon via syngas (CO and H ), which contains the coupling of CO with nitrite esters to dimethyl oxalate (DMO) and sequential hydrogenation of …

Shimmering "super earth" in the constellation discovered Cassiopeia

LONDON Scientists have discovered a new exotic planet outside our solar system in the Cassiopeia constellation. Located 21 light years away from us, this planet, dubbed HD219134 b, has a mass almost five times that of the earth which is considered a so-called "super earth". Unlike the earth, it probably does not have a solid core of iron, but is …
