Mystery of the “Big Bird” Neutrino –IceCube Observatory Detects One of the Most Dramatic Explosions in the Universe




Nearly 10 billion years ago in a galaxy known as PKS B1424-418, a dramatic explosion occurred. Light from this blast began arriving at Earth in 2012.Recently, the IceCube Neutrino Observatory at the South Pole found first evidence for a flux of extraterrestrial neutrinos, which was named the Physics World breakthrough of the year 2013. To date, the science team of IceCube Neutrino has announced about a hundred very high-energy neutrinos and nicknamed the most extreme events after characters on the children’s TV series “Sesame Street.”


Intelligent, Technological Exospecies Likely Evolved Before Us –“And They’re Extinct”





Are humans unique and alone in the vast universe? This question–summed up in the famous Drake equation–has for a half-century been one of the most intractable and uncertain in science. But new research shows that the recent discoveries of exoplanets combined with a broader approach to the question makes it possible to assign a new empirically valid probability to whether any other advanced technological civilizations have ever existed.

“Only one species of the billions of species that have existed on Earth has shown an aptitude for radios and even we failed to build one during the first 99% of our 7 million year history,” observed Charles Lineweaver a noted astrobiologist at the Australian National University.

The Great Mystery of Spacetime –“Beyond the Planck Scale”



Maxresdefault (1)


Our experience of space-time is that of a continuous object, without gaps or discontinuities, just as it is described by classical physics. For some quantum gravity models however, the texture of space-time is “granular” at tiny scales (below the so-called Planck scale, 10-33 cm), as if it were a variable mesh of solids and voids (or a complex foam). One of the great problems of physics today is to understand the passage from a continuous to a discrete description of spacetime: is there an abrupt change or is there gradual transition? Where does the change occur?
