One particle’s trek suggests that ‘spacetime foam’ doesn’t slow neutrinos‘Science News

SPEED TEST’ A neutrino blasted from a bright galaxy known as a blazar (illustrated) along with a flare of light reveals that neutrinos travel at roughly the speed of light. ‘

Moving on.

An intergalactic race between light and a bizarre subatomic particle called a neutrino has ended in a draw.

The tie suggests that high-energy neutrinos, which are so lightweight they behave as if they’re massless, adhere to a basic rule of physics: Massless particles travel at the speed of light.

Comparing the arrival times of a neutrino and an associated blaze of high-energy light emitted from a bright, flaring galaxy (SN Online: 7/12/18) showed that the neutrino and light differed in speed by less than a billionth of a percent, physicists report in a paper posted July 13 at arXiv.org.

The science behind Star Trek technobabble

This post is part of Science of Sci-Fi, Mashable’s ongoing series dissecting the science (or lack of science) in our favorite sci-fi movies, TV shows, and books.

Star Wars is all action. You know, X-wings and lightsabers and fully armed and operational battle stations.’

Star Trek ‘ at least, the original series, The Next Generation, Deep Space Nine, and Voyager ‘ was less … let’s say, explosive. There were a lot of sensor readings. Also, sensible debates. Several episodes centered around academic conferences.

In a cosmic first, scientists detect ‘ghost particles’ from a distant galaxy

When the sun was young and faint and the Earth was barely formed, a gigantic black hole in a distant, brilliant galaxy spat out a powerful jet of radiation. That jet contained neutrinos ‘ subatomic particles so tiny and difficult to detect they are nicknamed’ghost particles.’

Four billion years later, at Earth’s South Pole, 5,160 sensors buried more than a mile beneath the ice detected a single ghostly neutrino as it interacted with an atom. Scientists then traced the particle back to the galaxy’that created it.

The cosmic achievement, reported Thursday by a team of more than 1,000 researchers in the journal Science,’is the first time scientists have detected a high-energy neutrino and been able to pinpoint where it came from. It heralds the arrival of a new era of astronomy’in which researchers can learn about the universe’using neutrinos as well as ordinary light.

HPC Serves as a ‘Rosetta Stone’ for the Information Age

Today high-performance computing is at the forefront of a new gold rush, a rush to discovery using an ever-growing flood of information and data. Computing is now essential to science discovery like never before. We are the modern pioneers pushing the bounds of science for the betterment of society. — SC17 General Chair Bernd Mohr, J’lich Supercomputing Centre’

In an age defined and transformed by its data, several large-scale scientific instruments around the globe might be viewed as a mother lode of precious data.
