Today’s true strange news award goes to the creation of a fluid with negative mass.  Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It […]

Are quantum computers proof of multiple universes?

March 18, 2017

0

Quantum computers may be 100 million times more powerful than today’s computers and they may do that by computing results simultaneously in multiple universes. Really? Google and Nasa announced they were collaborating on the D-Wave X2 quantum computer, which they say is 100 million times faster than a conventional computer chip, in 2013. It can […]

ultra-rare “impossible” quasicrystal found in Russian meteorite

December 9, 2016

0

A quasicrystal’s atomic structure combines the symmetrical properties of a crystal and the chaos of an amorphous solid. Originating in outer space, these crystals aren’t just incredible because of how rare they are – their atomic structure is so peculiar, for decades their existence was dismissed as “impossible”, and they cost the scientist who first […]

Astronomers find matter that spontaneously pops in and out of existence

December 1, 2016

1

For the first time, astronomers have observed a strange quantum phenomenon in action, where a neutron star is surrounded by a magnetic field so intense, it’s given rise to a region in empty space where matter spontaneously pops in and out of existence. Called vacuum birefringence, this bizarre phenomenon was first predicted back in the […]

Large Hadron Collider discovers new sub-atomic particle, the pentaquark.

July 15, 2015

0

Psst. Wanna buy a pentaquark? Just ten years ago, they were called an experimental phantom. From 2005: “Physicists have come home empty-handed from a thorough hunting expedition for pentaquarks. The lack of evidence has led some to doubt that these odd subatomic particles, first sighted in 2002, actually exist.” http://www.nature.com/news/2005/050418/full/news050418-1.html However, now thanks to the […]

I want something I can’t find on the net: a visual interactive map of human problems and where we are along the various paths to solutions. I want everyone to be able to interact with it, add to it, vote on it! We have all this information, so organize it! Who can help? Google? I […]

Physics Lecture: Universe Could Wink Out of Existence

March 16, 2014

1

Sufficient dark energy to vaporize the earth and even the galaxy may exist: Matter is here now because the Higgs boson takes a non-zero value in empty space. All elementary particles that are the quanta of fields that couple to the Higgs field have their mass due to the Higgs spontaneous symmetry breaking. If a […]

Research: We Unconsciously React to Events Up to 10 Seconds Before They Happen

March 5, 2014

1

Can your brain detect events before they even occur? That was the stunning conclusion of a 2012 meta-analysis of experiments from seven independent laboratories over the last 35 years, which found that the human body “can apparently detect randomly delivered stimuli occurring 1-10 seconds in the future” (Mossbridge, Tressoldi, & Utts, 2012). In the studies, […]

Since we’re coming up on the Fourth of July, and towns everywhere are preparing their better-than-ever fireworks spectaculars, we would like to offer this humbling bit of history. Back in the summer of 1962, the U.S. blew up a hydrogen bomb in outer space, some 250 miles above the Pacific Ocean. It was a weapons […]

Albert Einstein’s Lost Theory Resurfaces, Shows His Resistance To Big Bang Theory

March 4, 2014

0

A manuscript that lay unnoticed by scientists for decades has revealed that Albert Einstein once dabbled with an alternative to what we now know as the Big Bang theory, proposing instead that the Universe expanded steadily and eternally. The recently uncovered work, written in 1931, is reminiscent of a theory championed by British astrophysicist Fred […]

Via Alex Tabarrok,Quanta magazine reports on a decades-long effort that has recently produced a radically simplified way of calculating quantum interactions. Instead of adding up millions or billions of terms, you simply sum the volumes of the pieces of a multi-dimensional object called a “positive Grassmannian.” Its inventors call this object an amplituhedron: The amplituhedron […]

Scientists shatter world record: Thinnest ever sheet of glass created at just ONE molecule thick … and all because of an accidental discovery

September 13, 2013

0

An accidental discovery has led to the creation of the world’s thinnest sheet of glass – at just one molecule thick. The ‘pane’ of glass is so impossibly thin that its individual silicon and oxygen atoms are clearly visible using a microscope. The discovery may someday lead to a defect-free, ultra-thin material that could improve […]
