oscillation

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

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

"These oscillations caused synchronisation failures between the electrical systems, leading to successive disturbances across the interconnected European network."

Right around the rocket launch site, local ecosystems are affected by explosive emissions, acoustic oscillations, and land and water use for installation.

But tracking these oscillations and trading them day by day or hour by hour can be a full-time job, and most people already have full-time jobs.
