The picometre's length is of an order so small that its application is almost entirely confined to
particle physics,
quantum physics, chemistry, and
acoustics.
Atoms are between 62 and 520 pm in diameter, and the typical
length of a carbon–carbon
single bond is 154 pm. Smaller units still may be used to describe smaller particles (some of which are the components of atoms themselves), such as
hadrons and the upper limits of possible size for
fermion point particles. The
Laser Interferometer Space Antenna (LISA) probe is planned for launch in 2034 to directly detect
gravitational waves and will measure relative displacements with a resolution of 20 picometres over a distance of 2.5 gigametres, yielding a strain sensitivity of better than 1 part in 1020. == References ==
