Teachers, you may want to consider adding the Monitoring Atmospheric Changes activity to your meteorology lessons. The activity has interactive tools to help students understand the factors contributing to hurricane intensity. This is a unique way for students to explore how sea surface temperatures affect the intensity of hurricanes.

Do ‘Black Holes’ rotate faster then the ‘Speed of Light’?
The sun rotates and its spinning action keeps the planets in Orbit.
So could a ‘Black Hole’ rotate so fast (faster then 186,000 miles
per second), that it keeps light from escaping?
It’s just a thought.. Not really sure how to prove it,
especially if one can’t see anything to measure speed.
Maybe experimenting with newtons’ laws on Gravity might
demonstrate it using a computer.

A: First, the spinning action of the sun does not keep planets in their orbit. The force of gravity together with the planets’ angular momentum conservation defines the orbit.
Black Holes do not spin faster than light because the measurement of speed only makes physical sense in locally inertial frames of reference that fall under the physics covered by special relativity, where c is the maximum speed of information or energy. A black hole can spin no faster than c, and this is called a Maximal-Kerr Black Hole, meaning that it has the maximum possible angular momentum.
You cannot explore Black Holes using Newtons Laws because the laws only work where spacetime is ‘flat’, and not curved as it is near Black Holes.
