Earth’s Magnetic Field is Shifting and Geologists Don’t Know Why
Something strange is happening with the Earth’s magnetic field and scientists are unsure why, according to a recent paper published in the journal Nature. A consortium of geologists in charge of the World Magnetic Model is having trouble keeping track of the planet’s magnetic north pole as it rapidly shifts from Canada to Northern Siberia.
Scientists updated Earth’s magnetic model in 2015, which is used for some pretty important things, including shipping navigation and GPS on smartphones. Their model was intended to last for at least five years, but due to the recent unexpected swing, it became outdated at some point in early 2018 and is now in need of adjustment.
“The error is increasing all the time,” said Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information.
Scientists say this shift is being driven by liquid iron sloshing around in the planet’s core, a natural process, but one that can vary as the flow changes. Over the past 20 million years, Earth’s magnetic field has consistently experienced a complete pole reversal – usually every 200-300,000 years.
At the moment, we’re long overdue for one of these events, with the last reversal having occurred 781,000 years ago. No one is quite sure what the consequences will be on modern infrastructure when and if that reversal happens. Many take ease in the fact that pole reversals have occurred hundreds of times in the planet’s history without catastrophe, but again, the effect on modern technology remains unknown.
Some scientists have pointed to this shift as a potential culprit in a slew of recent dolphin and whale beachings as well as other unexpected animal die-offs. It’s believed the planet’s natural magnetic field is necessary to some of these animals’ navigation when traveling and communicating over great distances underwater. One NASA scientist is currently looking into this potential connection.
In 2016, a larger-than-usual magnetic pulse shot up from South America, which scientists believe played a role in furthering the recent shift. However, they’re still unsure whether it will continue on this course, or even what will happen at all.
Could we be on the precipice of a massive geomagnetic reversal, or is this just due to slightly-more-anomalous-than-usual activity in the Earth’s core? And what’s even more pressing – what kind of effects is this having on us?

A New Phase of Matter Appears to Defy Laws of Thermodynamics
Scientists have created a new phase of matter known as time crystals, a quantum phenomenon appearing to defy the laws of thermodynamics. Could this discovery upend our understanding of classical physics?
A team of researchers developing Google’s Sycamore quantum computer announced the successful creation of a time crystal that lasted for 100 seconds. This novel phase of matter appears to defy the second law of thermodynamics, which states that entropy, or chaos and disorder, always increases in an isolated system. In other words, energy must be put into a system in order to maintain structure or motion. But time crystals have been observed to maintain a constant state of flux, without losing any energy.
Dr. Simeon Hein, director of the Institute for Resonance, explains the science behind this strange phenomenon.
“Crystals are in everything we do—they’re in watches—they’re in so many things because they’re regular, they create evenness, they create this consistency. And just like their pattern is very consistent, the energy that crystals transmit turns into a very regular pattern which is why you can use a quartz crystal in a watch,’ Dr. Hein said.
“You can put a noisy electrical signal in but it will come out as a very consistent beat, and that created the idea for some people, in this case, Frank Wilczek from M.I.T. in 2012, to propose the idea that you not only had crystals in space, you could have crystals in time. You could create an oscillating circuit, using specific quantum principles, you could create a very constant quantum beat.”
Time crystals have been described as the first “out-of-equilibrium” phase of matter, meaning they maintain order while in an excited state. But how do time crystals accomplish this, without expending energy?
“At a quantum level, they’re getting energy from something called the Zero-point energy field. The Zero-point energy field is the lowest ground state of quantum matter, but the lowest state doesn’t mean absolute zero like nothing’s happening. The quantum ground state is actually the base state of the universe, where even though there’s nothing happening, the field itself generates energy, causing random fluctuations and particles to pop out of nowhere, and all sorts of really interesting effects that normally, I should say most of the time, we don’t see in our regular, physical reality,” Dr. Hein said.
“So these coherently entangled particles would be deriving their energy from the quantum vacuum field. But if they’re getting their energy from the quantum vacuum, instead of our classical world, you can’t see any reason why they would eventually have to wind down like our regular clocks would, and energy would dissipate.”
With this new discovery of time crystals appearing to defy the second law of thermodynamics, how has mainstream science reacted, or tried to reconcile this paradox?
“A lot of these quantum phenomena seem to defy classical physics, the whole idea of quantum entanglement suggests faster than light interaction or communication, Einstein called it ‘spooky action at a distance,’ and experiments later confirmed that you could take pairs of particles and separate them, and you could do something to one of them, and the other particle would immediately react at farther and farther distances away,” Dr. Hein said.
