"Physicists Achieve Record-Breaking Signal Duration: 0.000000000000000005 Seconds"

Scientists from the University of Konstanz have developed a method using femtosecond light flashes to generate electron pulses with a duration of around five attoseconds, one of the shortest signals ever produced by humans. This breakthrough offers a higher time resolution than light waves and opens up new possibilities for observing ultrafast phenomena, such as nuclear reactions. The researchers achieved this by using pairs of femtosecond light flashes to generate extremely short electron pulses in a free-space beam. The results have been published in the journal Nature Physics.
