A student researching dark matter has taken the following notes:
• Dark matter makes up approximately 27% of the universe • It does not emit, absorb, or reflect light • Scientists infer its existence from gravitational effects on visible matter • Multiple experiments are attempting to detect dark matter particles • Understanding dark matter could revolutionize physics
The student wants to explain how scientists know dark matter exists despite not seeing it. Which choice most effectively uses relevant information from the notes?
Dark matter makes up approximately 27% of the universe.
Although dark matter cannot be seen because it doesn't interact with light, scientists infer its existence from its gravitational effects on visible matter.
Multiple experiments around the world are attempting to directly detect dark matter particles.
Understanding dark matter could revolutionize our understanding of physics.
Correct Answer: B
Choice B. Explains invisible nature and how gravitational effects reveal existence.
