I know that in church people would talk about angels being there. Is there any way to know the difference...if it's an angel or a spirit? (I know the skeptics will say "there's no such thing as spirits or angels...but c'mon and put your 50cents worth in & get your 2 pts.)

He is omnipotent (all powerful). Astronomical data says universe began 13.7 billion years ago; earth was not formed unitl 4.5 billion years ago. Why would God wait 9.2 billions years after creating the universe to create earth? And, waited another 4.5 billion years to create humans, if we are really God's untimate reason for creating the universe? Anyone have any answers? He must have had a reason.

I always hear about "cold spots" and "cold rooms" and "chills". Whenever I was in church...at healing services.....I'd feel "warmth"..they said that was the healing power. It would usually make me cry. (happy crying) Have any of you ever felt that warmth?

Neutron stars are amazing. They are the matter at its extremest state.

But, how do they get their energy? Do they convert the neutrons into energy? Or is this just energy stored from the supernova of the big star that the neutron star came from?

They have to have a source of energy somehow, otherwise, you wouldn't get things like magnetars.

A spring is hung from the ceiling. When a block is attached to its end, it stretches 2.0 cm before reaching its new equilibrium length. The block is then pulled down slightly and released.

What is the frequency of the oscillation?

Here is a little background of what I am about to ask. The house next door was built by our best friend's grandparents. They moved out because of financial problems and the house was lost to foreclosure. Our best friend's dad was raised in the house, and of course he was like a dad to my husband and me. A couple of years ago he died tragically in a freak accident about 1/2 mile from our houses. Since they lost the house a couple of people have lived there, but the most recent ones destroyed the home and had got convicted of things they had done to children there last month.

For the past month every Saturday night, our TV turns on to a program that "Dad" used to watch all the time on Saturday nights on PBS. There is no explanation as to how it gets turned on to that show. Then I could swear that I have seen him walk past our kitchen window on our covered porch. I am not scared, and feel he is making his presence known. Our best friend one morning saw it too.

In "Teaching Creation Science in Public Schools," Duane Gish suggests Creationist alternatives to radiometric dating, specifically those taking into account:"the amount of helium in the earth's atmosphere produced by radioactive decay of uranium and thorium, the decay of the earth's magnetic field, the pressure of oil in petroleum deposits, the presence in rocks of pleochroic haloes of very short-lived radioisotopes, the rate of cooling of the earth (taking into account heat produced by the decay of radioactive substances), the Poynting-Robertson effect, the lifetime of comets, and the time required for clusters of galaxies to disperse."

Are these factors really being ignored by Evolutionists?
And if so, why doesn't anyone make instruments taking these factors into account?
Would they really register significantly different results?

I'm trying to reduce the iron in FeCl3, from Fe (III) to Fe(II), using ascorbic acid, but I don't know how to write the balanced chemica equation. (I think it has something to do w/adding H20 as a reactant)? Is this redox??

ascorbic acid is C6H8O6
