Earth's Magnetic Field Once Collapsed. Humans Survived. Here's How
Study Finds ^ | April 18, 2025 | StudyFinds Staff

Posted on 04/21/2025 6:44:52 AM PDT by SunkenCiv

Earth's Northern Lights typically dance near the poles, but 41,000 years ago, they lit up skies over North Africa and Australia. New research reveals how dramatically Earth's magnetic field weakened and shifted during an event called the Laschamps geomagnetic excursion, potentially influencing human evolution at a pivotal moment in our history...

During the Laschamps excursion, Earth's magnetic field weakened to just 10% of its current strength, while the magnetic poles shifted dramatically away from the geographic poles...

Using advanced computer modeling, the research team reconstructed Earth's magnetosphere during five key periods of the excursion. At its peak around 40,977 years ago, Earth's protective magnetic bubble shrank dramatically – from its normal extent of 8-11 Earth radii (51,000-70,000 km) to just 2.43 Earth radii (15,498 km).

The magnetic field also transformed from a simple north-south configuration to a complex arrangement with multiple magnetic poles scattered around the planet...

The Laschamps excursion coincided with a critical period in human history – as modern [sic] humans (Homo sapiens) spread throughout Europe, Neanderthals disappeared, [sic] and humans created the first known cave art [sic]...

Modern humans also invented tailored clothing during this period, with archaeological sites containing not just hide scrapers but also sewing implements like needles and awls. This clothing would have allowed for greater mobility while providing coverage and potentially protection from increased radiation.

IOW, he’s a loon.

That’s what I thought until I viewed the video. The tracking and trajectory of the Black Star is verified through SolarScope.

lol... you’re right, but admittingly, id say 97% right. there is enough evidence to suggest something did happen. not many know but I have forever thrown in little bombs not to cause trouble, but to trigger discourse. try to anywyas...

I don’t want to read the whole article, does it mention how it affected the refrigerator magnets of the time?

Dunno about refrigerator magnets but the megaliths at Stonehenge are storied to have been levitated into place. That doesn't make sense in today's world, but perhaps it was possible then if the magnetic fields were many times stronger.

Lets get to the heart of the matter. A model was built on a few data points of a complex system. Just like all the climate models that proved global cooling, warming, changing.

A model like statistics never gives you an answer, at best it might give you another question at best.

They built a model here on a few datapoints. The researchers hopefully understand this (sometimes I doubt this) but the public does not.

Close Eyes, Head Shake, sigh, what could possibly be wrong with the theory?

There are lots of places in the world that aren’t dependent on the electric grid.

Those dependent are going to have more trouble, but mankind will manage.

I’m currently actively trying to not buy meat to force me to delve into the depths of the freezers to avoid that sort of thing.

Diversity is not our strength, the Earth should have one single magnetic monopole! ;-)

Suspicious Observers on YouTube is one us, and has a great channel that explains the cyclical nature of the sun and its impact on the Earth. He has extensively talked about the current geomagnetic excursion happening right now with magnetic North. Currently, the pole is drifting towards Siberia at a rapid rate. It sounds like events like this happens roughly every 6,000 years. When this happens the Earth’s magnetosphere weakens which causes solar storm radiation to wreak havoc at a larger scale in our atmosphere. Remember last year when we had northern lights appearing in the southern US? Well, the storms triggering them shouldn’t have been nearly as powerful to cause the phenomenon that far south.

Would could possibly go wrong with reading the entire topic?

More garbage in, garbage out techniques, in my opinion.

I'll choose to ignore & dismiss the "study" as junk science.

I plead guilty.

Will read it.

-

Modern humans, who had been around for the previous 250,000 years, picked over the remains of the advanced Neanderthal civilization, after they departed for a better, more stable planet.

The lesson is don’t go around naked. Wear clothes.

Primitive humans knew how to hunt, fish and gather. They didn’t have to google how to find food.

Not to mention compasses - Neaderthals didn't disappear, they just got really really lost.

That clears up a lot of the mystery of those times.

You differentiated between primitive and we.
