"marcus harding" Discussed on Progressive Talk 1350 AM

"Hey, Brain stuff. Lauren Vogel Bomb here on the northern coast of the Yucatan Peninsula near the town of Chicxulub. Mexico is a crater about 120 miles in diameter. It's about 190, kilometers. Ask for the created this crater was about six miles that's 10 kilometers wide and hit the Earth 65 million years ago. In spite of these immense measurements, the crater is hard to see. Even if you're standing right on its rim to get a good map, NASA researchers examined it from space. 10 years before the 1990 discovery of the chip Philip Crater, physicist Louise Alvarez and geologist Walter Alvarez, a father son team proposed a theory about the impact that we know today created it. They noted increased concentrations of the element. Iridium in 65 million year old clay. Radium is rare on Earth, but it's more common in some objects from space like Meteors and asteroids. According to the Alvarez theory, a massive asteroid had hit the Earth blanketing the world in a radium. But a shower of particles wasn't the only effect of the collision impact caused fires, climate change and widespread extinctions at the same time, Dime stores which until then had managed to survive for 180 million years. Died out. Geophysicist Doug Robertson of the University of Colorado, Boulder theorize is the impact heated Earth's atmosphere dramatically, causing most big dinosaurs to die within hours. This mass extinction definitely happened. Fossil evidence shows that about 70% of species living on earth at that time became extinct. A massive die off marks the border between the quotations and tertiary periods of Earth's history, which are also known as the age of reptiles and the Age of mammals, respectively. Today, scientists call the extinction the KT event after the German spellings of pretentious and tertiary KT event had an enormous effect on life on Earth. But what would have happened if the asteroid had missed? Would it have led to a world where people and dinosaurs would co exist or one in which neither could live? In a world where an asteroid whizzed past earth instead of crashing down with the force of 100 million tons of TNT, life could have progressed much differently. 65 million years ago. Some of the animals and plants that are common today we're just getting started. These include placental mammals, which are mammals that develop inside a placenta in the womb and angiosperms, which are flowering plants. Insects that rely on flowers such as bees were also relatively new. Many of these life forms thrived after the KT event, and without that mass reptilian extinction to clear the way they may not have found ecological knishes to fill. In this scenario, today's world might be full of reptiles and short on mammals, including people. Even if the asteroid hadn't hit dinosaurs and other quotations, life forms might have become extinct anyway. Some dinosaur species had started to dwindle long before the asteroid's impact. This has led many researchers to conclude that the asteroid was just one aspect of a complex story. Other global catastrophes like massive volcanic eruptions in what is now India most likely played a role. Also the earth changing landscape is the supercontinent Pandya broke up into today's continents probably had something to do with it, too. Then there's another argument that the Chicxulub asteroid hit the earth too early to have caused the extinction. Researchers guarded Keller and Marcus Harding both conclude that the impact took place 300,000 years before the end of the quotations period. Heller theorize, is Chick Philip Impact was one of at least three massive collisions. Harding argues that theory, Diem layer didn't come from the Chick fil of Asteroid, but from another event, such as a series of.

Like, you smart water has added electrolytes for taste and great tasting water helps you stay hydrated, feeling refreshed and ready to take on your day. Refresh yourself with smart water. Welcome to brain stuff from how stuff works. Hey, brain stuff, Lauren Vogel bomb here on the northern coast of the Yucatan peninsula near the town of chick. Love. Mexico is a crater about one hundred twenty miles in diameter. That's about one hundred ninety kilometers the asteroid that created this crater was about six miles. That's ten kilometers wide and hit the earth sixty five million years ago in spite of these immense, measurements, the craters hard to see even if you're standing right on its rim to get a good map. Nasa. Researchers examined it from space. Ten years before the nineteen ninety discovery of the chick fil crater, physicists, Louise, Alvarez and geologist. Walter Alvarez, a father son team proposed a theory about the impact that we know today created it. They noted increased concentrations of the element iridium in sixty five million year old clay radium is rare on earth, but it's more common in some objects from space like meteors and asteroids, according to the Alvarez theory, a massive asteroid had hit the earth blanketing the world iridium, but shower of particles wasn't the only affect of the collision the impact caused fires climate change and widespread extinctions at the same time dime stores, which until then had managed to survive for a one hundred eighty million years died out, geophysicist Doug Robertson of the university of Colorado at boulder theorizes, the impact heated earth's atmosphere dramatically causing most big dinosaurs to die with an hours this mass extinction. Definitely happened fossil evidence shows that about seventy percent of species living on earth at that time. Became extinct. The massive die off marks the border between the Cretaceous and tertiary periods of earth's history. Which are also known as the age of reptiles and the age of mammals respectively today, scientists call the extinction decay t- event after the German spellings of Cretaceous and tertiary the t- event had an enormous effect on life on earth. But what would have happened if the asteroid hadn't missed would it have led to a world where people in dinosaurs would coexist or one in which neither could live. In a world where an asteroid whizzed past earth instead of crashing down with a force of a hundred million tons of TNT life could have progressed much differently. Sixty five million years ago, some of the animals and plants that are common today. We're just getting started these include placental mammals, which are mammals that develop inside a placenta in the womb and angiosperms, which are flowering plants insects that rely on flowers, such as bees were also relatively new many of these life forms thrived after the t- event, and without that mass reptilian extinction to clear the way they may not have found ecological niches to fill in this scenario. Today's world might be full of reptiles and short on mammals, including people. But even if the asteroid hadn't hit done stores and other Cretaceous life forms might have become extinct. Anyway, some dinosaur species had started to dwindle long before the asteroid's impact. This has led many researchers to conclude that the asteroid was just one aspect of a complex story. Other global catastrophes. Massive volcanic eruptions in what is now. India most likely played a role also the earth's changing landscape as the supercontinent Panja broke up into today's continents. Probably had something to do with it too. Then there's another argument that the chip to love asteroid hit the earth too early to have caused the extinction. Researchers Gerda Keller and Marcus Harding, both conclude that the impact took place three hundred thousand years before the end of the Cretaceous period. Keller theorizes chick fil impact was one of at least three massive collisions Harding argues at the iridium layer didn't come from the web asteroid but from another event such as series of meteors burning up in the atmosphere. He bases. This theory on ROY particles objected during the impact a most of these are in an older layer of the earth than the Katie iridium layer, according to both of these points of view the absence of the club. Asteroid strike may not have had a big affect on the k t extinction earth was a warm planet for most of the time that dinosaurs lived after the end of the Cretaceous period, the world got a lot colder and experienced several ice ages. Whether dinosaurs could have survived such change in climate is debatable. It's hard to come to a definitive conclusion about what the world would look like today without the chicks love impact. But the question of whether people in dinosaurs could have coexisted is a captivating won the ideas, president in everything from the Congo legend of mock lame Obembe to King Kong to the pervading kitsch of the Flintstones. Then of course, there's the prevailing scientific theory about the origin of birds that they are in essence dinosaurs that we are coexisting with today.
