Online devastation calculator

[blobrana]

Hehe,
Those crazy scientists from the University of Arizona have developed a handy calculator that you can use to determine your fate in the event of an asteroid impact.

It calculates the blast, depth of ejecta, and the force of the air blast at a distance from ground zero. Now you can see if you'll be safe from the devastation of an asteroid strike, or if you'll need to hop in your car and drive... far.
calculator...



(tip, try a speed of 30,000 km/sec)

[sry, mustn`t laugh at others misfortune]

Anyway, i`m trying to get a friction burn...

Hum,
Nice link there...

And in  the news...
Near Earth Object Observation Program experts have told the Senate subcommittee on Science, Technology and Space, that they are on schedule to finding everything bigger than 1 kilometer (0.62 mile) in diameter that might approach the planet (that`s city killers).

"The survey officially started in 1998 and to date more than 700 objects of an estimated population of about 1,100 have been discovered, so the effort is now believed to be over 70 percent complete and well on the way to meeting its objective by 2008."

So things don`t looks so bleak...  :-)

@Karlos
Hum,
How about dark matter?
Most of this exist  as a `halo` around our galaxy but some would have collected  within large gravitational objects (er, like stars, or our sun)...
They wouldn`t really react with anything there, being WIMPS*,  but would interact gravitationally...

If you could collect enough wimps an inject them into the Martian core, then you would increase the gravity of Mars...




[WIMP = weakly interactive massive particle]

[blobrana]

Doh!





Oh !
Er, by creating a small black-hole (bigger gravitational well) and `fishing` for them in the sun...?

[blobrana]

Yep,
we've fished them out of the sun.
And they would orbit around with mars...

[yes, this solar system is unstable and eventually they , and mars, would be swallowed by the sun or flung out into deep space]



the only problem is how to get rid of the black-hole... (evaporating only leave nothing, me thinks)

[blobrana]

@Karlos
No never read the book...

hum, the  warping of space , as an alternative to using a black hole  (messy), would be a better solution....


Er, now all we have to do is discover 25^th century physics...or perhaps some alien artifact... :-)
