suggests it was actually thousands of small impacts. Tens of thousands of small impacts, to be more precise. MIT researchers, led by Professor Hilke Schlichting, say that number would have been sufficient to kick up clouds of gas with enough force to eventually jettison Earth entire primordial atmosphere into space. The scientists arrived at their conclusion by calculating the effects of various-sized objects striking the Earth. An impactor as massive as Mars would have generated an immense shockwave through our planet interior. The result would be global simultaneous earthquakes鈥攚hose force would ripple up into the atmosphere, ejecting it into space. However, a collision that size would also have melted the entire interior of the planet, creating a homogenous slurry. The researchers doubt that th

Instead, the scientists found that a constant bombardment of smaller rocks would have wreaked havoc more efficiently. And the timing would have been right for such a scenario. Around 4.5 billion years ago, wh

During the course of the group research, however, an inevitable question arose: What eventually replaced Earth atmosphere Upon further calculations, Schlichting and her team found the same impactors that ejected

To discover the tumor, the researchers used a micro-CT scan machine which cuts up an image into different frames. The 1.18-inch long Neanderthal rib bone was sliced to 500 distinct frames which let researchers study every micron of the bone, thus revealing the tumor.
