SUMMARY
The cross product of the unit vector i and its negative counterpart -i is definitively zero. This conclusion is based on the fundamental property of cross products where any vector crossed with itself, including its negative, results in a zero vector. The relevant equations include i x i = 0 and i x (-i) = 0, confirming that the operation yields no resultant vector.
