chinese build ‘black hole’ prototype
New Scientist posts First black hole for light created on Earth but if you read the article you learn that the black hole built by Tie Jun Cui and Qiang Cheng at Southeast University in Nanjing works on microwaves, not light waves. “I expect that our demonstration of the optical black hole will be available by the end of 2009,” Cui is quoted as saying in the article.
Based on research published earlier this year by Evgenii Narimanov and Alexander Kildishev of Purdue University in West Lafayette, Indiana, this is a fascinating development of unexpected new technology. Who knew you don’t need massive gravitational fields to create black holes?
