Attoseconds aren’t fast enough for particle physics

<p>One of the biggest news stories of 2023 in the world of physics was the Nobel Prize in Physics, awarded to a trio of physicists who helped develop methods&nbsp;<a href="https://bigthink.com/starts-with-a-bang/attosecond-spectroscopy-nobel-prize/" rel="noopener ugc nofollow" target="_blank">for probing physics on tiny timescales:&nbsp;</a>attosecond-level timescales. There are processes in this Universe that happen incredibly quickly &mdash; on timescales that are unfathomably fast compared to a human&rsquo;s perception &mdash; and detecting and measuring these processes are of paramount importance if we want to understand what occurs at the most fundamental levels of reality.</p> <p>Getting down to attosecond-level precision is an incredible achievement; after all, an attosecond represents just 1 part in 10&sup1;⁸ of a second: a billionth of a billionth of a second. As fast as that is, however, it isn&rsquo;t fast enough to measure everything that occurs in nature. Remember that there are four fundamental forces in nature:</p> <p><a href="https://medium.com/starts-with-a-bang/attoseconds-arent-fast-enough-for-particle-physics-4ff5865658d3"><strong>Website</strong></a></p>
