Scientists create a fluid with negative mass

April 15, 2017


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


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 […]

Why not have real wind up cars?

January 6, 2017


Think about the implications of spring stored energy scaled up to real cars. Is it possible? An aspiring aerospace engineer blogging at Astrochara, shared with Truestrange a video of a mousetrap powered model car that will travel 60 feet. The plans are available so you can make one: In my AP Physics class we were required […]

ultra-rare “impossible” quasicrystal found in Russian meteorite

December 9, 2016


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


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


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.” However, now thanks to the […]

March 21, 2015


The expansion and collapse several times of the shock wave is similar to what would be predicted if an atomic bomb was detonated far enough under the ocean.

A map of human problems

June 21, 2014


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


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


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, […]

Plans to Destroy the Earth’s Protective Radiation Belts

March 4, 2014


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


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 […]

Scientists ‘freeze’ light for an entire minute

February 21, 2014


In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute. It sounds weird and it is. The reason for wanting to hold light in its place (aside from the […]

Oldest star in Universe discovered

February 10, 2014


Astronomers in Australia have found the oldest known star in the universe, a discovery that may re-write our understanding of the universe directly following the Big Bang. The team from Australian National University (ANU) say that the star, located around 6,000 light years away from Earth, is roughly 13.6 billion years old. This means it […]

Vitamin E and Other Antioxidants Dispel Static Electricity

September 20, 2013


It might be called a shock finding. Coating plastic or rubber materials with antioxidants such as vitamin E stops static charge from building up on the polymer’s surface, chemists report today. The discovery could prove a cheap solution to problems such as dust clinging to plastic, static electric shocks, or the sparks that damage television […]

Maybe Space-Time is Just an Illusion

September 19, 2013


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


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 […]

Why Does Popcorn Pop?

August 28, 2013


A popcorn kernel is a cereal grain seed. It is made up of four major physical structures: 1 The Pericarp seed coat or outer hull: a hard outer thin covering. 2 The Endosperm: starchy part that forms the bulk of the kernel and consists almost entirely of starch along with smaller amounts of protein, fat, […]

Astronomic news: the universe may not be expanding after all

August 14, 2013


… Every now and again, cosmologists decide that the universe needs a rethink. For example, for the past century, they have likened it to an inflating balloon, decorated with galaxies. Now one theoretical physicist has pricked this textbook idea by coming up with an heretical suggestion – namely, that the universe is not expanding at […]
