Weird question..
Let's say you wanted to create a magnetic field around Mars large enough to protect it from the sun's radiation with a giant electromagnet.
1) How would you arrange your giant wire(s)? Drill straight through Mars or lay the wires on the planet's surface?
2) How thick would your wires be?
3) If the ITER fusion reator works perfectly as planned, how many of them would you need to power your electromagnet?
Just a good guess is all I need, I don't need exact numbers. Thanks.

Rᵤᵥ - ½gᵤᵥR ∝ Tᵤᵥ
First off, sorry I've been gone for so long. For some reason I couldn't get on the site, and it just randomly started working again. So, anyway, here we go:
Well, I imagine the best way to do it would be something like how Earth's works, with a giant spinning superheated ball of iron. The iron is already there, we'd "just" need to heat the core and start it spinning again. I don't even have a rough idea as far as any numbers go.
Time in physics is simply what's measured on clocks. The rate at which clocks tick can vary with the geometry of spacetime. For example, clocks tick slower when they are near a gravitating body such as the Earth or the Sun, but the difference is pretty much negligible. You only start to really notice these effects when you're talking about extremely dense objects like neutron stars or black holes.
The energy-momentum distribution in spacetime is related to the curvature of spacetime by the Einstein Field Equations.
This is called the Mpemba effect, and there are a number of different causes, such as the levels of dissolved gasses, the amount of water that evaporates, etc.

Is time a behavior of mass, or is it defined differently? Does that question actually have a solid answer?
