I was reading a few weeks ago at Space.com that they have determined the rotation of two Black Holes. One was spinning at a rate of 960 revolutions per second, and the other was revolving at a rate of 1,110 rps. That is fast. I then wondered what the rotation of the Sun was in relation to the Black Holes. Well, the rotation of the sun is 26 to 28 days, the rotation period depends on which part of the Sun you are analysing.

This brings me to another thought. When you look at the sun( never look at the sun directly) you are seeing the sun as it was 8 & 1/2 min ago. That always amazes me. When you look up at the night sky, you are seeing photons(light) that have traveled millions of light years, and the photons could be 13 billion years old that are colliding with your cornea as you look up.
