oscillation

In metals, these oscillations occur when electrons behave like tiny springs, vibrating in response to magnetic fields.

However, interest in evolving dark energy was vigorously rekindled last year from the combination of supernovae, baryon acoustic oscillation, and cosmic microwave background data from the DES, DESI, and Planck experiments.

Understanding a process called neutrino oscillation, where these particles change "flavors" as they move, could help explain why matter triumphed over antimatter.

The cause of the galaxy's vast oscillations is still uncertain.

That plasma carried acoustic oscillations, although still not at an audible range.
