Another news story about scientists being shown up by a teen also proves to be completely wrong
First the story appeared on April 4 in Germany's 'leading' tabloid ("I have calculated the end of the world ... and NASA says, I'm right"), later in more serious papers ("Nico and the end of the world") - and today, thanks apparently to an AFP story where the writer hadn't found it necessary to check anything, it has taken off around the world. Alas: it's absolute nonsense! The claim is that a 13-year old German schoolboy "discovered" - while working on an entry for a major German science competition - that the 2036 impact probability of asteroid Apophis is not 1:45,000 as the NASA calculation says but actually 100 times higher. Because during the 2029 approach the asteroid would hit a geostationary satellite and be deflected into a much more dangerous orbit. The newspapers also claimed that this boy not only was awarded several prizes for his paper but that NASA had "conceded" that he got it right and they were wrong. We're all doomed, right?
Well, here's what NASA's NEO guru Don Yeomans told this blog yesterday: "We have not corresponded with this young man and this story is absurd, a hoax or both. During its 2029 Earth close approach, Apophis will approach the Earth to about 38,900 km, well inside the geosynchronous distance at 42,240 km. However, the asteroid will cross the equatorial belt at a distance of 51,000 km - well outside the geosynchronous distance. Since the uncertainty on Apophis' position during the Earth close approach is about 1500 km, Apophis cannot approach an Earth satellite. Apophis will not cross the moon's orbital plane at the Moon's orbital distance so it cannot approach the moon either."
Meanwhile David Appell comments on the Kristen Byrnes story:
Yesterday NPR published one of the most atrocious, absolutely embarassing pieces of scientific journalism I have ever witnessed. ...
Ms. Byrnes' Web site is an absolute joke, full of errors, entirely unscientific. For example, her graph of CO2 levels in the atmosphere showed it flat until about 1950, which is simply wrong. I corresponded with her for months and months about this, as did many other bloggers, until she finally hid her error without acknowledgement of what was correct.
And Eli Rabbett grits his teeth and goes through Byrnes' arguments.

Maybe I should do a story titled "Toddler finds mistakes in news report, journalist apologizes". Making stuff up has never been so fun.

I think bi is on to something.A scorecard for toddlers and perhaps one for pre-teens... http://abcnews.go.com/WaterCooler/wireStory?id=4576912

Hmm, I'm taking my three year old son to a science museum this Saturday. If he comes up with any iconclastic scientific insights, my fellow Deltoid readers will be the first know.
