Question

The James Webb telescope, recently launched in space, is giving humankind unprecedented access to the depths of time by imaging very old stars formed almost 13 billion years ago. Astrophysicists and cosmologists believe that this odyssey in space may even shed light on the existence of dark matter. Dark matter is supposed to interact only via the gravitational interaction and not through the electromagnetic-, the weak- or the strong-interaction. This may justify the epithet “dark” in dark matter. Based on the above paragraph, which one of the following statements is FALSE?

Correct answer (D) If dark matter was known to interact via the strong-interaction, then the epithet “dark” would be justified. Solution The passage states that the epithet "dark" is justified because dark matter is supposed to interact only via gravitational interaction and not through electromagnetic, weak, or strong interactions. If dark matter were known to interact via the strong interaction, the premise that it interacts only via gravity would be false, and the specific justification provided in the text for the name "dark" (lack of interaction with other forces) would no longer hold. Therefore, statement (D) is logically inconsistent with the paragraph's reasoning. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
