Your numbers are wrong. Its about 1 million miles per second. That's nearly as fast as your ability to come up with a stupid idea and complain about it.
Of course, but does saying "5.918×10^30 to 9.206×10^30 lbs" really help envision what we're talking about? The differences between 10^10 and 10^30 or a billion billion and a billion billion billion is completely lost on most people. If we're going to convert to something a layman can understand, we could at least try "500,000 to 700,000 times the mass of the Earth" before trying to shoehorn familiar units into completely unintelligible numbers.
"27,000 km/s" I am now Even "16,700 miles per second" would be easier to grasp, I think. Even better would be saying "something moving that fast around Earth would go around it four times in under a second."

You did get me on this one though, I misread the heading.

less than four seconds to go from one side of the Earth through the middle to the other side and back. About two seconds to go around the Earth at the equator.
Also, what the hell are you doing?
Arguing on the internet.
It's a big job, but somebody's gotta do it.
You guys are kinda charged up. I'm staying neutron.
Ok, I should probably go home and watch the Packer game now.
This is the sort of reason that colonizing other star systems should happen at some point in time: Redundancy.In my professional out-of-my-ass opinion, I'd expect anything hitting the star to vaporize into a flash of gamma radiation and plasma pretty much instantly.

This thread had my mind going today. If you dropped the teaspoon a meter, or more realistically space debris hit the star - what would the impact be like?
I wouldn't think there would be a crater, but would the material instantly flatten out?
Would it be instantly spread across the entirety of the surface to keep a spherical form?
Would there be even an instant where material is ejected only to fall back to the surface with tremendous force, or does the weight and gravity of the material and "star" keep it from ever leaving the surface?
I wondered the same and simply can't envision what might happen. Its just to extreme to get a grasp on it without having the mathematical background to figure it out. The star is made of nothing but neutrons it seems, so i'd expect nothing but a simplified version of the object to survive and merge with the star almost instantly. I'd expect any explosion to be very brief and return to the star's surface in an instant flash, like a really quick spark.

Just within this solar system you've got hazards: Big CMEs that would seriously disrupt our technology-based lives, or mile-wide asteroids that drop by to visit at 70,000mph.
Then nature scatters enormous sterilizers throughout the galaxy. I hope life on your planet rolled +20 Resistance to Gamma Radiation!
Sure, it's not likely to happen, but when/if it does, the consequences could include extinction.

Yeah for sure. But that's what you need to make the earth collapse. Condense it to the size of a small marble (3cm...the whole earth into a 3cm ball) and boom, you got a black hole.
There are about 5 grams of water in a teaspoon and a neutron star is ~100 quadrillions times as dense as water, on average, according to Wikipedia.
I'm cheating, this site calculates the force of impact of 5,000,000,000,000,000 grams dropped one meter on Earth as 490000000000000000N of force, which calculates to 49,966,094,436,000 metric tons of force.
Does that sound right? Nature is pretty amazing.
Not necessarily. Black whole density goes down with mass, the black hole at the center of our galaxy is less dense than water.
Huh???Not necessarily. Black whole density goes down with mass, the black hole at the center of our galaxy is less dense than water.
Huh???
Black hole's radius is directly proportional to its mass (google Schwartzchild radius), while it's density is directly proportional to mass, and inversely proportional to radius cubed.Huh???
Yes. Based on general relativity alone... The belief (hope?) is that proper quantum treatment will remove singularity, once we have unified theory of quantum gravity.The density inside supermassive black holes' event horizons is low for the reasons above. The black hole itself is a singularity with infinite mass.
