Space Videos's video: The Asteroid That Destroyed Dinosaurs Had a DEADLY Companion

Thanks For Watching: Support us - http://www.ko-fi.com/spacevideos Were dinosaurs wiped out by two massive asteroid impacts, not just one? In this deep dive, we explore the mind-blowing discovery of the newly revealed Nadir Crater off the coast of West Africa, which might be linked to the infamous Chicxulub impact. Could these two cosmic events have teamed up to cause the ultimate extinction? With groundbreaking 3D seismic imaging, scientists are uncovering secrets of the past, painting a more complex picture of Earth's history. Join us as we break down the evidence, from mega-tsunamis to global chaos, and consider what this means for our understanding of the dinosaurs’ extinction. Buckle up – it's a journey through time and space! The huge asteroid that hit Earth and wiped out the dinosaurs 66 million years ago was not alone, scientists have confirmed. A second, smaller space rock smashed into the sea off the coast of West Africa creating a large crater during the same era. It would have been a “catastrophic event”, the scientists say, causing a tsunami at least 800m high to tear across the Atlantic ocean. Dr Uisdean Nicholson from Heriot-Watt University first found the Nadir crater in 2022, but a cloud of uncertainty hung over how it was really formed. Now Dr Nicholson and his colleagues are sure that the 9km depression was caused by an asteroid hurtling into the seabed.
