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. Sign up for our free Indy100 weekly newsletter But a more interesting theory is that they are huge chunks of an ancient planet that hit the Earth around 4.5 billion years ago. 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.

Mark Zuckerberg’s Meta is finally launching Threads, the text app that it hopes could overtake Twitter. It arrives at a particularly difficult time for Elon Musk’s Twitter. The site has faced a range of technical issues in recent days, which it has blamed on AI services scraping its site. “Threads, an Instagram app” will arrive in the App Store on Thursday morning US time. Threads aims to take on the app with a range of features that are similar to those offered by Twitter, according to its App Store listing. “Threads is where communities come together to discuss everything from the topics you care about today to what’ll be trending tomorrow,” it reads. “Whatever it is you’re interested in, you can follow and connect directly with your favorite creators and others who love the same things — or build a loyal following of your own to share your ideas, opinions and creativity with the world.” It is just the latest in a long line of apps to try and take over from the increasingly troubled Twitter in offering text-based updates. But almost all of those apps – from the decentralised Mastodon to Donald Trump’s Truth Social – have struggled to find users.
