New Research Suggests That The Dinosaur-Killing Asteroid Struck Earth At The ‘Deadliest Poasible Angle’
Numerous reports have been published in the past few days, highlighting new research that the dinosaur-killing asteroid that struck the Earth some 66 million years ago, did so at the worst possible angle, super-charging the impact and effects of the explosion. The new research by the Imperial College London was published last Tuesday in the journal Nature Communications. Gareth Collins, a geophysicist and the lead researcher of the project, described it as a “worst-case scenario” when it made impact 66 million years ago,” George Dvorsky wrote in a May 27, 2020 post to the technology blog, GIZMODO.com. “The asteroid strike unleashed an incredible amount of climate-changing gases into the atmosphere, triggering a chain of events that led to the extinction of the dinosaurs,” Dr. Collins said. “This was likely worsend by the fact that it struck at one of the deadliest possible angles.”
“The impact delivered copius amounts of carbon dixoide, water vapor, and suiphur into the atmosphere, resulting in an impact winter that wiped out 75 percent of all life on Earth, including all non-avian dinosaurs,: Mr. Dvorsky wrote.The buried remnant of this event, the Chicxulub impact crater, is located in Mexico’s Yucatan Peninsula, and measures some 240 kilometers (150 miles) wide,” he added. New analysis of deeply buried soil/crust in the Yucatan, as well as computer modeling and simulation helped scientists narrow their findings and conclude the deadly/existential asteroid struck the Earth on a 60 degree trajectory. The asteroid is believed to have been between 6.2-9.3 miles thick, and bigger than Mount Everest; and was travelling at an estimated speed of 44,000 mph.
“We know this was this was among the worst-case scenarios for the lethality on impact, because it put more hazardous debris into the upper atmosphere and scattered it everywhere — the very thing that led to [an impact] winter,” Collins said.
“Beyond the asteroid strike, other factors also led to the dinosaurs demise,” Mr. Dvorsky wrote. “Soot from the ensuing wildfires has also been implicated in the ensuing mass extinction by blocking the sunlight. Volcanic eruptions may had also played a role,” he added.
“As if to add insult to injury,” Mr. Dvorsky ends, “research from 2017 showed the asteroid struck a rather unfortunate spot. The Yucatan Peninsula is one of the few spots on Earth to have the exact chemical compounds, namely hydrocarbons, to spew so much carbon dioxide and sulphur into the upper atmosphere. A perfect storm indeed,” he concludes.
Steve Busatte, a paleontologist from the University of Edinburgh said, “if things went just a little bit differently, and the asteroid was a near miss, or even if it hit the Earth at an ever so slightly different angle, the dinosaurs might have survived.” he said.And that means he added, that the dinosaurs might still be alive today — and, there would be no humans. So ironically, the existential asteroid strike paved the way for the birth of the human race. RCP, fortunascorner.com
