Question

1. what kind of information do black hole detectors not provide?

precise timing
photon intensity
specific positional information
power of a black hole

Explanation:

Black hole detectors can provide information such as precise timing (related to gravitational wave signals which have timing aspects), photon intensity (in some detection mechanisms), and power of a black hole (through energy - related measurements). However, they do not provide specific positional information as they are mainly focused on detecting the presence and some characteristics of black holes rather than pinpointing an exact position in a detailed spatial sense.

Answer:

specific positional information
