Read the excerpt from a black hole is not a hole. i found lots of great information in science magazines, such as scientific american, astronomy, and sky and telescope. these led me to other useful resources. when it was time to get to the details, i looked at scientists' reports, along with summaries of the reports, in scientific journals. how can these scientific magazines be evaluated as credible sources?
the reader must look for professional photos.
the reader must look for current copyright dates.
the reader must look for well-written opinions.
the reader must look for a persuasive argument.
