Re: Ask a Scientist

mmm, that's a good one (and not a topic i know much about)

tides are caused by gravity. Gravity is a force which has a very small observable effect (compared with electric or magnetic fields) however on a large scale, when we consider the mass of say, the moon, it is quite noticeable. not sure whether that helps or not, but i'll think more on this today.

Why is tidal movement only detectable on a large scale ?
