Chinese scientists confirm dark matter not detected

由清华大学主导的中国暗物质实验合作组近日在美国《物理评论D》杂志上发表了最新暗物质实验结果，确定性地排除了美国一个实验组几年前给出的暗物质存在区域，人类探测器迄今尚无一真正发现这种看不见的物质。[查看全文]

(ECNS) -- A study published by China Dark Matter Experiment in scientific journal Physical Review D has disproved a lab result in 2011 about areas where dark matter might exist.

The experiment, led by Tsinghua University, used the same detector as the one utilized by US-based CoGeNT Dark Matter Experiment, but failed to find the mysterious substance.

Scientists in many countries are searching for evidence to prove the existence of the hypothetical dark matter. The invisible element makes up 27 percent of the Universe and roughly 68 percent of its energy. Everything ever observed with available instruments adds up to less than 5 percent of the Universe.

China set up the world's deepest underground lab in Sichuan province during 2010, and has started expansions this year to allow more experiments to be carried out.
