Gravitational waves vs ULF Radio waves
LIGO itself is designed to be insensitive to ULF waves. If it wasn't, the strong terrestrial ULF background would interfere with its operation.
ULF waves cannot propagate through interstellar space, ...

Gravitational waves vs ULF Radio waves
LIGO's mirrors are charged as calculated in this answer. The LIGO team has a technique to measure and keep this charge from getting too large over time. However, the calculation shows that a ULF (~...

Conceptually, what does the amplitude term in the wave equation represent when describing a gravitational wave?
To get started, let's think about a simpler wave first. For a wave on string, the amplitude tells you the displacement from the rest position of the string, $\Delta y$. If a string is strung ...
