Re: Mathematical limits for computer programs

However, the examples with the twin prime problem and the odd perfect number are also not valid arguments, in my point of view, because these problems are not solved yet, however, I don't think they are not decidable.

No. You can't see gamma rays in a cloud chamber.

Re: Does light exert gravity?

Whatever you call it, equivalent mass or relativistic mass: It does have a mass that you can measure and that is transferred to, say, an atom that absorbs the photon. And the mass interacts with other mass through gravity. It is an actual mass that has actual effects. That's the point.

Well, almost. Photons have momentum, which as you point out is conserved for any closed system. But in relativity, a particle moving at the speed of light cannot have a rest mass, and the other way around. Yes, I know. This is because Hamilton mechanics say v=dH/dp=pc²*((m0c²)²+p²c²)^(-1/2) and if ...

But if God can be sure what we will do, how can we not? I mean, if he already knows, this means, whatever we do is definite, we cannot change it. It means we are deterministic. And therefore it means we have no free will. Somehow. (Which I think is true anyway, but not because of religious reasons)
