Well why you're about -- about your business on Monday we came oh so close has taken a direct hit from an -- We IP space terms dangerously close means about 17 of the distance of the moon -- and it.
Scientists say the space rock is the same size as an asteroid exploded near sadness fear.
Above Siberia about a century ago that wiped out an 800 square mile pour salt.
I was the sports.
He killed -- who's an astrophysicist.
He's also the author of physics of the impossible how you doing served very good welcome back here I said 17 of the distance of the moon.
It it it sounds kind of close the space turns wasn't really.
It was a whisker in terms of astronomy -- Disney -- then this is the moon is simply grave the earth.
They came within about the distance of artists space satellites.
The good news is that it was a near -- we dodged a bullet the bad news is that if it hit the earth.
It would have been the forests of -- twenty megaton hydrogen bomb.
It would have wiped out 500 square miles of real estate all of New York City -- all of London if it had hit.
And I should mention every hundred years one of these things about the size of a football field.
Actually hits the -- Thus those so we've got -- -- look forward to it now.
Are there -- people out there are responsible for for watching now for these things well he caught astronomers with their pants down.
How many astronomers scanned this -- every night.
You could put them inside a mcdonalds hamburger restaurant real -- you're talking about maybe 2030 people every night had this thankless job of scanning the heavens.
And only later this year and the end of this year NASA will finally send up a satellite.
That we'll systematically.
Scan the heavens because we live in the middle of a cosmic shooting gallery.
So word wrists every day is what you're saying which means we should probably start her own personal asteroid fun.
Well -- -- ASA paid.
Something this big -- the area we now know about once every five years.
Throughout human history that's been the way it was however we didn't know about that.
We were blissfully unaware that these big boulders in space just -- the planet earth.
Hit the -- perhaps once every hundred years in the army now we know all these guys sit there that McDonald's well I mean you described in the number 2030 people.
-- they amateurs they -- working for somebody most of them are amateurs only recently as the real magnitude of the threat has become known.
The European nations the Arab Boris and NASA.
Had begun to allocate some of the resource is just standing there haven't -- to look for these things but for the most part it's a very faint hearted effort.
But if it was just a whisker how -- message.
Well you know these things are very hard to track we track about several thousand of -- he goes near earth objects that cross the orbit of the -- But every once in awhile something pops up on -- nowhere and -- us totally off guard.
You know -- luck if it's on its way back and it's out there and events I mean you believe eventually we're going to be hit by one of these things whether it's tomorrow or.
A thousand years from now could you do any thing.
To stop it right now the answer is no forget the movies like army did in and dug deep impact.
Our space shuttle cannot reach into deep space our space shuttle simply goes around the planet -- around and around and around.
We can't even approach asteroid -- At the earth from on its face.
But -- means of course that we've physicists have made plans.
21 day perhaps send a rocket to nudge an asteroid out of the way but that's still decades into the future.
Now I feel better pick it up -- up so much but guess that makes me TO.
Thank you meet you -- With -- here in the first -- his physics class and heart he's smart man that's not easy -- we bring a month at what are you doing the year 2029.
Replace about it about the year 2036.
Cents at the next big threat.
You know I asteroid fun and I started Monica -- to Louisiana LA I ticket out of the bunker with your canteen.
