Select the correct answers from the list,
Dark matter does or does not I’m so bright does not. What does emit radiation and has or has not been served directly.
It seems like there's a bit of confusion in the wording of your request, but I'll try to clarify based on what I think you're asking about dark matter and other astronomical phenomena:
1. Dark matter does NOT emit radiation (such as light or any other form of electromagnetic radiation).
2. Dark matter has NOT been observed directly (because it does not emit or absorb light or any other electromagnetic radiation).
3. Objects like stars, which emit radiation (including visible light), are considered "bright" and HAVE been observed directly.
The correct statement concerning dark matter is: "Dark matter does not emit radiation and has not been observed directly."
