A friend of yours who is a science fiction fan hears you talk about the fact that astronomers now believe that the mechanism for the large energy output of quasars involves a supermassive black hole. He challenges you, saying something like "Oh come on, every science fiction fan knows that nothing, not even light, can escape from a black hole! How can a black hole be an energy source!?" How would you respond to his objection?

Imagine that you are a safe distance from a black hole, watching as a giant indestructable clock (with its second, minute, and hour hands lit by an internal white light source) fell towards the event horizon. What would you see?

the hands on the clock would appear to move more and more rapidly, and the clock's appearance would slowly turn more and more blue. Then it would suddenly vanish.
the hands on the clock would appear to move more and more rapidly, and the clock's appearance would dim, and slowly turn more and more red, until the clock vanished.
the hands on the clock would appear to move more and more slowly, and the clock's appearance would would dim and slowly turn more and more reddish. Before it was too dim to see, it would seem to be virtually motionless.
the hands on the clock would appear to move more and more slowly until they began to turn backwards at twice the radius of the event horizon. Its colors would also change from redish to bluish at this po

Before we discuss whether Intelligent Design is a scientific theory, we need to be sure of what our definition of a scientific theory is. I'm looking forward to reading your answers!

I heard that it's already been done and we humans are a race of biters that are trying to copy the mechanics of alien spacecrafts that have infinite fuel engines that run on black matter. Is this true?

My theory of the Big Bang is this. For the Big Bang to actually have happened, there would have HAD to have been some sort of Energy behind it's happening correct? There absolutely had to be. My theory is that God was the energy behind that. I don't believe that the universe just appeared and all the planets were created on their own. What do you think about this?

If the human race were to successfully create the means to travel throughout space for an indefinate period of time, how much would that actually benefit us? What do you think we would find along our travels?

Here's the detailed info on where the showers are, but what does it mean in layman's terms:

The duration of this shower extends from July 15 to September 11. Maximum seems to occur during August 1 (Solar Longitude=128.6°) from an average radiant of RA=306.7°, DECL=-8.3°.

If I'm in North America, would I take a compass, point 0 degrees to the north, then look at the 306.7 degree mark and face that direction? Then look up 8.3 degrees (If 90 degrees is straight up, then about 1/10th of the way between the horizon and straight up).

Does this sound reasonable, or am I way off?
