But scientists have noticed something strange in their measurements of seismic waves from earthquakes and nuclear tests. Earth\u2019s inner core appeared to stop spinning. Even stranger, it started spinning backwards relative to the mantle. What\u2019s going on at the heart of our planet? And what does it mean for us on the surface?\n\nTo clarify for those asking: The 'reversal' discussed in recent papers refers to the core's rotation speed relative to the mantle, creating an apparent backward motion - like a car passing a bus. \n\n\u2580\u2580\u2580\u2580\u2580\u2580\n\n0:00 Journey to the Centre of the Earth\n4:03 Earth\u2019s Missing Mass\n6:09 Measuring Earthquakes\n12:33 Cold War Discovery\n17:16 Earthquake Doublets\n19:03 70-Year Cycle\n21:43 How It Affects Us\n\n\u2580\u2580\u2580\u2580\u2580\u2580\n\nSubscribe to the channel! \nhttps:\/\/youtube.com\/@AstrumEarth \n\nSupport our Patreon and you\u2019ll get early access to Astrum Earth content, before anyone else: https:\/\/bit.ly\/4aiJZNF \n\n\u2580\u2580\u2580\u2580\u2580\u2580\n\nCheck out the other Astrum channels for videos about space and astronomy:\nAstrum: https:\/\/www.youtube.com\/@astrumspace \nAstrum Extra: https:\/\/www.youtube.com\/@astrumextra \n\nAstrum Podcast on Spotify: https:\/\/open.spotify.com\/show\/6jPRrbq3o3dpvBb173ZTKi?si=a90d3efe3b704c83 \n\nAstrum Infographic Artwork: https:\/\/electrify.art\/collections\/astrum \nAstrum Displate Posters: https:\/\/astrumspace.info\/Displates \nAstrum Merch: https:\/\/astrum-shop.fourthwall.com\/\n\nJoin us on the Astrum discord: https:\/\/discord.gg\/TKw8Hpvtv8 \n\n\u2580\u2580\u2580\u2580\u2580\u2580\n\nReferences:\n\u201cEarth\u2019s inner core may have reversed its rotation\u201d, via sciencenews.org https:\/\/astrumspace.info\/corereversal \n\u201cFrom core to crust: defining Earth\u2019s layers\u201d, via calacademy.org https:\/\/astrumspace.info\/earthlayers \n\u201cDiscovery of Earth\u2019s core\u201d, via colorado.edu https:\/\/astrumspace.info\/corediscovery \n\u201cTectonic implications of the Shillong Plateau earthquake\u201d, via agupubs.onlinelibrary.wiley.com https:\/\/astrumspace.info\/shillongeq \n\u201cEarthquake waves and how they travel through Earth\u201d, via pnsn.org https:\/\/astrumspace.info\/seismicwaves \n\u201cOn the constitution of the interior of the Earth\u201d, via geologie.ac.at https:\/\/astrumspace.info\/oldham1906 \n\u201cInge Lehmann and the discovery of Earth\u2019s inner core\u201d, via amnh.org https:\/\/astrumspace.info\/ingelehmann \n\u201cSeismological evidence for differential rotation of the Earth's inner core\u201d, via columbia.edu https:\/\/astrumspace.info\/corebacktracking \n\u201cMultidecadal variation of Earth\u2019s inner-core rotation\u201d, via nature.com https:\/\/astrumspace.info\/corevariation \n\u201cInner-core backtracking by seismic waveform change reversals\u201d, via nature.com https:\/\/astrumspace.info\/corewaveforms \n\n\u2580\u2580\u2580\u2580\u2580\u2580\n\nCredits:\nNarrator: James Stewart\nWriter: Matt Bone\nVideo Editor: Matt Jamie\nAnimator: Peter Sheppard\nResearcher: Shourya Shrivastava\nThumbnail Designer: Peter Sheppard\nPublishing Lead: Georgina Brenner\nProduction Manager: Raquel Taylor\nEdit Producer: Poppy Pinnock\nProducers: Alex McColgan, James Stewart\nHead of Astrum: Jess Jordan\nCreator of Astrum: Alex McColgan\n\n\u2580\u2580\u2580\u2580\u2580\u2580\n\n#AstrumEarth #Astrum #EarthsCore","thumbnailUrl":["https:\/\/i.ytimg.com\/vi\/hse8miXdksE\/default.jpg","https:\/\/i.ytimg.com\/vi\/hse8miXdksE\/mqdefault.jpg","https:\/\/i.ytimg.com\/vi\/hse8miXdksE\/hqdefault.jpg","https:\/\/i.ytimg.com\/vi\/hse8miXdksE\/sddefault.jpg","https:\/\/i.ytimg.com\/vi\/hse8miXdksE\/maxresdefault.jpg"],"uploadDate":"2026-01-05T17:08:27+00:00","duration":"PT23M25S","embedUrl":"https:\/\/www.youtube.com\/embed\/hse8miXdksE","publisher":{"@type":"Organization","@id":"https:\/\/www.youtube.com\/channel\/UCWBtLCE-BnzZx3DneqDiXWQ#Organization","url":"https:\/\/www.youtube.com\/channel\/UCWBtLCE-BnzZx3DneqDiXWQ","name":"Astrum Earth","description":"From Alex McColgan and the Astrum team comes an illuminating new adventure that turns our gaze homeward.
