With potential energy, what matters is the difference in potential energy, not the energy in absolute terms. To simplify calculations, the gravitational potential at infinity is arbitrarily set to zero. This gives objects that are nearer than infinity (to any object that attracts them gravitationally), a negative potential energy.With potential energy, what matters is the difference in potential energy, not the energy in absolute terms.

Zero times infinity is defined as "indeterminate".
Because zero multiplied by any number is always zero, but anything multiplied by infinity is infinity. Zero times infinity is being pulled both ways. Also, the definition of infinity is any number x divided by 0. When you multiply zero by infinity, the zeroes "cancel out", leaving absolutely nothing behind.
Log zero is not defined, and if it were defined, it would be more likely to be minus infinity than infinity.
No. Zero multiplied or divided by anything is zero.
