Killer asteroid flattens New York in simulation exercise

Simulated women and minorities hardest hit...

$5 billion in improvements.

Is that a book or a movie. Looks interesting. Anytime I need a ride off this rock, I use my Electronic Thumb. And a towel. Always have a towel handy.

[EasySt]

Just something I nicked in my travels... ;-)

Nothing ruins property values more than an impending asteroid strike, except muslimes moving into the neighborhood. Tbats worse.

Did you mean Deep Impact?

This 'exercise' is nothing but scare mongering. It's so unrealistic that it's not even disguised. The land area of large cities around the world is tiny compared with all the rest of the millions of square miles of totally uninhabited area. The odds of an errant asteroid hitting, not one, but two of the largest cities in the US, is vanishing small. Just think of throwing random darts at a spinning globe of the earth. What are the odds of one of the darts hitting, not one, but two US large cities? Note that the known meteor 'explosions' over the last century, or so, hit mostly uninhabited areas.

The line that indecisiveness prevented a second deflection attempt is equally absurd. It was demonstrated that the first deflection strike actually worked. How could anyone prevent another, especially when the new target is New York City?

If only. Too bad it's only a simulation.

You are not alone.......

[Flintlock]

AND..................that’s a BAD thing?

[unread]

Gee, I was hoping it would be DC....

[Vermont Lt]

Oh jeez..yes. Sudden impact was on the other day. It was in my head. I got the names confused.

So in about 8 years there’s a 1% chance that an asteroid will hit earth. OK, but how do they come up with the idea it will hit a major city in the US such as Denver or NYC?

Have they calculated the exact trajectory of the object relative to what part of the earth will be in that path at that exact minute? (keeping in mind the earth is both rotating around the sun and spinning at the same time)

IMO this is climate change grade science at work creating fear. The so called scientists live in their big city democrat bubble and only worry about a rat infested metropolis. If they knew for fact it would hit Rapid City, SD they could care less about those people and worry about the dust fallout drifting towards rat cities.

Meteor gas been floating around YouTube, maybe some of the PTBS can watch it.

[ProtectOurFreedom]

“most impacted”

heh, heh. Is that like “most squashed”?

[ProtectOurFreedom]

If it was a simulation, then why couldn’t they tune a few parameters to assure 100% success? How do you program a simulation to predict failure?

I suppose they used Monte Carlo Simulation and ran a hundred thousand simulation runs with a fault tree and assigned probabilities.

The notion of us unintentionally breaking off a chunk of the asteroid which then hits the earth has been around a long time.

[ProtectOurFreedom]

“Simulations don’t provide adequate training exercises.”

Absolutely. We need to run some carefully controlled experiments.

[tet68]

Women, children and minorities most impacted.

Hello, I’m from the DHS and I want to order
150 million doses of Exlax...

[Redcitizen]

Groovy. :)

Celestial mechanics can do some pretty nifty computations.
