Many of us look to the stars for answers to life’s most complex questions. But actually, some of the greatest mysteries lie beneath our very feet. One might think we’d know the Earth pretty well by now but, in fact, our planet’s core remains shrouded in enigma. Indeed, there are two gigantic blobs located beneath Africa and the Pacific Ocean that occupy around six per cent of the world’s entire volume. And yet, we’re still not entirely sure what they’re made of or where they came from. There are a number of hypotheses, including that they are piles of oceanic crust that have accumulated over billions of years.

To give an indication of just how massive these things are, the structure under Africa – an area known as Tuzo – is thought to be around 800km (497 miles) tall – the equivalent of some 90 Mount Everests stacked on top of one another, as IFLScience notes. The problem with determining the origin of these monster formations is that there are no direct ways of observing the Earth’s core. The deepest hole humans have ever dug – branded the "entrance to hell" – reached a pretty staggering 12,263m (40,230ft), but that doesn’t even come close to breaking through the crust to the layers beneath. Our most effective tool for analysing what lies beneath the ground is a technique called seismic tomography, which looks at how waves of energy travel when earthquakes occur. Since rocks and liquids have different densities, the waves move through them at different speeds. By measuring the tremors from different points on the surface, geologists can determine what kind of material the waves are travelling through and, in so doing, map out the Earth’s interior. It was by using this technique that the two unusual structures – known as large low shear velocity provinces (LLSVPs) – were found. Waves travel more slowly in these areas – fondly known as “blobs” – than through the surrounding lower mantle, indicating that they’re made of something different. We can’t tell what this material is based on seismic tomography data alone, but some scientists like to believe that they are the remnants of an ancient planet called Theia – an idea known as the “giant impact hypothesis”. According to this hypothesis, around 4.5 billion years ago, a Mars-sized object collided with the Earth. This impact not only created the planet we call home today, but also threw off enough rock to form the moon that lights up our night skies. Some scientists suggest that some of Theia’s leftovers also sunk to the bottom of the planet, probably settling somewhere above the core – thereby forming at least one of the two LLSVPs. More Updates About Strange Blob Structures Inside Planet Earth youtu.be Experts have been investigating the area for decades but there’s still no way of knowing for sure just what these two giant blobs are. Still, studies into Theia have offered important insights into how the possible collision might have kickstarted key plate tectonic and mantle motion inside our planet – crucial processes for establishing the world on which we live. It’s also a useful reminder that we still have so much to learn about our planet and where we came from. Have your say in our news democracy.

High school students are having less sexual intercourse

In today’s world, social media is usually the culprit for circulating conspiracy theories and stories. The recent viral discussion online is the Russian sleep experiment, as some wonder if it was real, after a video claimed a film covering the incident is being made. The story first surfaced on a Creepypasta forum. The post described to readers a Soviet-era experiment where scientist created a stimulant that allowed soldiers to go without sleep for 30 days. As the story goes, in order to prove and showcase the effects of the stimulant, five prisoners were selected and promised freedom at the end of the test. The five men were then locked in the chamber and gas was pumped inside it. However, the story reveals that the experiment did not go well as all the men began to experience symptoms of sleep deprivation. Halfway through the 30 day time period, the scientists conducting the experiment were forced to enter the chamber as there was no visibility due to the gas. When they opened the door one prisoner was dead and the other four had several horrific injuries that were presumed to be self-inflicted. Despite some belief that the Russian sleep experiment is real, it is in fact a work of fiction, as is almost all stories posted to Creepypasta. Stories are shared on the platform to scare readers, with the website initially reposting stories found on existing platforms such as 4chan and Reddit. Over time, the site allowed people to post anonymously and share their own stories. However, it is true that a movie has been based on the story. On Apple TV+ you can stream The Sleep Experiment if you’re in the mood for a horrifying watch. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
