Deep beneath the waves of the North Sea, the seafloor is behaving in an unexpected way.
Deep beneath the waves of the North Sea, the seafloor is behaving in an unexpected way. There, scientists have discovered hundreds of vast sand mounds, some on the scale of several kilometers across, that, according to a release from the University of Manchester in the UK, "defy fundamental geological principles".

"Quiet Pulse" and "Another World"
Light shines dimly through the wall of an ice cave in this photograph by Marie-Line Dentler. Shaped by melting, pressure, freezing, and fracture, these structures are dynamic and ethereal. (Image credit: M. Dentler; via Colossal)

The Earth's magnetic field has reversed 183 times over the past 83 million years, averaging one reversal every 450,000 years, with the most recent occurring 780,000 years ago.
Why sea-level folks are technically younger than people living at higher altitudes.
Another finding is that time runs more slowly at Earth's core than on its surface. If you could compare 2 perfect atomic clocks, one that has been situated at the Earth's center since the planet formed 4.5 billion years ago & another atomic clock at Earth's surface since it formed, the Earth's core would be 2.5 years younger. The reasons for the time difference have to do with Einstein's Theory of Relativity, which says that gravity slows time. So, going underground moves you closer to Earth's center, where gravity is stronger, so you age more slowly underground. Of course, we're talking nanoseconds, so even if you could live at the Earth's core for 80 years, you would slow your aging by trillionths of a second. Biology cannot detect this.
Living in Denver, which is 1 mile above sea level, would age 40 nanoseconds more per year than someone in Florida would. Over 80 years, a Denver citizen would lose 3 microseconds of their life compared to someone at sea level. That's because sea level has stronger gravity, which means time runs more slowly, whereas high altitudes have weaker gravity, so time runs slightly faster. A nanosecond is 1 billionth of a second.
Although the laws of physics don't meaningfully affect Earthlings, GPS satellites do care, as they are 12,500 miles (20,000 km) above Earth; therefore, with weaker gravity, time runs faster. But satellites have another physics principle that affects them: speed. High speeds slow down time, & GPS satellites move through space at 8,700 mph (14,000 km/h). The net effect is that GPS clocks run 38 microseconds faster per day than Earth's clocks. If uncorrected, GPS positions would drift by 6 miles (10 km) per day. So engineers constantly adjust satellite clocks. In low-Earth orbits (like the ISS), speed wins, meaning slower time overall, but at higher orbits, weaker gravity wins, which means satellites age faster than Earth clocks. Humans never notice the atomic time differences because our lives don't require nanosecond precision.
These laws of physics technically affect astronauts as well. For example, astronauts living on the ISS age slightly slower overall because of the speed at which the space station is traveling, moving at 17,150 mph (27,600 km/h), which overrides the fact that there is less gravity at 260 mi (400 km) above Earth. Weaker gravity makes them age faster. The higher altitude effect applies more to GPS satellites than it does to the ISS. Spending a full year on the ISS would give them a net gain in lifespan of 0.01 seconds. Even a lifetime in orbit (80 years) would garner them an extra 0.8 seconds of life—not even a full second.
A 8.1 m-class solar flare yesterday blasted a large and fast coronal mass ejection (CME) directly towards Earth, with impact expected around 06:00 am UTC on Dec. 9th.
At the exact same time yesterday (literally) a magnitude 7.0 earthquake ruptured along the border of Alaska and Canada, with 150+ aftershocks now having ruptured after the main event.
The epicenter for that earthquake has strange alignments to notable ancient sites around the world, and the crazy timing of it exactly with the solar flare hints at greater forces at play.
With the upcoming solar storm impact continue the story and perhaps bring about certain revelations?
And what about that unusual burst of energy observed in the Schumann Resonances shortly after the 8.1 M-flare and M7.0 earthquake combo?
Geophysicist Stefan Burns with a special report.
Scientists find two huge 'islands' hidden beneath Earth's surface Deep within Earth’s mantle, more than 2,000 kilometers below the surface
Deep within Earth’s mantle, more than 2,000 kilometers below the surface, lie two massive, continent-sized structures. These enigmatic formations are not only significantly hotter than their surroundings
Nothing like having a shitty course in uni, thinking you, at most, barely passed the exam only to get the second highest grade for the whole course. Suck my estrogen-filled dick earthquake seismology!!!
(Any seismologists reading this post should know I do actually think seismology is cool but this one course suuuucked)
