What has the lowest albedo?
Understand the Problem
The question is asking about the material or surface that reflects the least amount of sunlight, which is related to the concept of albedo, a measure of reflectivity. This inquiry may involve various types of surfaces in nature or synthetic materials.
Answer
black hole
The object with the lowest albedo is a black hole.
Answer for screen readers
The object with the lowest albedo is a black hole.
More Information
Black holes have virtually zero reflectivity, implying an albedo value close to 0. In terms of common Earth materials, coal and fresh asphalt are also known for their extremely low reflectivity.
Tips
Confusing materials with astronomical objects might lead to a misunderstanding. Ensure the context is clear—whether it pertains to celestial bodies or terrestrial materials.
