Layman question:

As I understand it, a Black Hole is a "tear" caused in three-dimensional space-time by an infinitely dense object.

All depictions I've ever seen of Black Holes show them to be like infintely deep whirlpools. I assume that these holes "fall off" in all directions, depending on their formation.

So what determines the direction in which a Black Hole forms? Are there variations in the "density" of space-time, such that different Black Holes "fall off" in different directions?

Also, do all known black holes "rotate" in the same direction?

VLBI is so cool. I had the opportunity to reduce VLBI data with this sort of thing when I was a wee grad student (and I even published!). I recently came upon the opportunity to possibly do more work along these lines, and I'm contemplating the offer. It's a very exciting field, with great opportunities.

"... It revealed details in the observed objects more than 100 times finer than the Hubble Space Telescope can see."

Ok... for a standard telescope (approximately):

. resolution (theta) = 1.22 Lambda/Diameter

where theta is the angle of resolution,
Lambda is the wavelengh in meters
and Diameter is the telescope's diameter in meters.

So, the Hubble has an average wavelength (lambda) of half-micron, and a diameter of 2m. (rounded).

Then, if VLBI has an effective diameter (baseline) is 30,000,000 meters (30k km) and the wavelength is decimeter, then it would have 100 times the resolution of Hubble @ half micron wavelength and 2 meter diameter.
Works out to a good approximation.

Amazing... a radio telescope system with 100 times the resolution of Hubble....
Then imagine a visual interferometer system with Earth-moon baseline!!
