चर्चा में क्यों
The article highlights how a failed 1970s CSIRO experiment to detect exploding black holes led to the development of Fast Fourier Transform techniques now essential for Wi-Fi and Bluetooth.
पृष्ठभूमि
In the late 1970s, Australian radio astronomers from the CSIRO attempted to detect exploding black holes. The experiment failed its primary goal but resulted in mathematical techniques to filter cosmic noise and mitigate multipath interference.
