There was this guy named Gideon back in the days of old Israel, and wanted light to pursue his enemies. The day was ending and it seemed like his enemies would manage to give him the slip when he prayed and God made the sun stand still in the sky for several hours.
Now, obviously God did not actually make the sun stand still. He could have done so by moving the sun or stopping the Earth's rotation but that would kill just about anyone on the planet and that, I am told, is a bad thing. God probably just bent the rays of the sun as if using a really big prism or mirror and thus threw sunlight down to Gideon's area, making it seem that the sun stood still. (much like the Earth's atmosphere lengthens the duration of the day, only moreso)
Since magic can be used to pull meteors and satellites out of the sky, can it bend/reflect some sunlight so that a couple of zones in the dark hemisphere get it for a few moments? In theory, a manmade space station with a big mirror can do it - what kind of spell power would one need to do the same?
Here's my take on this...
Sure, magic can be used to pull meteors and satellites out of the sky. It can also be used to stop the earths rotation, move the sun, or blow up the moon. It requires a combination of two things to accomplish such larger-than-life feats though. Calculation, and Power.
McCoy did indeed pull a satellite out of the sky, but what you have to ask is how. The direct method would be to grab it with an arm of magic energy and slam it where you want it to go. This would require minimal calculation, and a LOT of Power. On the flip side, if you know the forces already acting on the satellite, you should be able to calculate where to strike it with a minimal force push to throw it out of orbit and onto your enemy's head. This would require a LOT of calculation and minimal power. I use the term minimal on a relative scale in both instances.
Another option would be to open a portal that takes the satellite from where it is, and puts it where you want it to be (changing the direction of its velocity would help) I have no idea what sort of calculation or power this would require.
Redirecting sunlight would be a similar issue. Space is really big. Really really big. I don't think I can fit enough 'really's in to convey the range of this sort of spell. To reflect light correctly, you would need to conjure a mirror-like object in space. You would need a fair bit of both power and calculation. (It'd be easier to shoot down a satellite). You would need to sustain these constructs at a rediculous distance as well. Alternatively, you could generate a mini black-hole to bend the light to your will ... but please don't, I like not having black-holes eat the planet.
There's also another issue here. As far as mirrors are concerned, there's already a giant mirror reflecting the sun's light to the earth at night. We call it Moon. Somehow reflected sunlight doesn't have the same effect as direct or preserved sunlight. It could be because it lacks the full color spectrum or because the moon neutralizes the holyness or mystical properties of the sunlight, either way, you'd have to know what you're doing and make a mirror construct that bypassed this weakness.
In other words, unless you have special arrangements, it would be easier to incinerate the Vamps than to bring the light from the sun. And I think it'd be more likely for God to slow the flow or time in Gideon's area. [/color]
