It seems we all survived the intragalactic close shave

Glad to see that we're all still here to talk about food...and it eat it too!
 
Tonight: the delayed Valentine's Dinner, since the wife was at a school event last night. The menu includes scallops, shrimp, cooked spinach, and broccoli. The kid wants fish sticks.
 

"It seems we all survived the intragalactic close shave"
 
That's what the dinosaurs said.
 
Successful insertion of alien lifeforms is my guess.
 
 

It is reassuring to me that:
 
a) we detected at a great distance a 150' diameter rock coming at us
 
and
 
b) we (and the Japanese) have successfully landed craft on asteroids and a comet.
 
So, I would have to think that we could detect something truly dangerous in more than enough time to knock it a degree or two off a collision course with a nuke set off in the vacuum of space.

Yeah... you'd only have to hit it a little a couple million miles out, in order for it to change it's course. Then again, if it was hit incorrectly, it could send it screaming directly at earth instead of a near miss. I wouldn't want to be the guy making that calculation.

It amazes me that we could detect the near miss, but couldnt "see" the one that exploded over Russia.  Exploded with the force of 20 atomic bombs, if it exploded 5 to 10 miles lower over 1 million people would be gone.
 
We dont have the knowledge that they think they have, there is no way we can detect all these near earth objects with 100% accuracy.
 
We dodged the intergallatic bullet this time.
