Do solid structures or objects vibrate or just the particles that make up the solids/structures?

Question

Solid objects do not vibrate. (That we can see and/or feel and/or hear.) However, molecules inside a solid vibrate. Does this mean the solid structure or object itself vibrates or just the particles that make up the solid? For this example, let’s use a night stand as the example.

Answer 1

Generally speaking, solid objects that, say, have a radius of more than 0.01 mm do not vibrate as a whole. Yes, their individual particles always vibrate, including those on the surface, but the object itself is not really going to be changing locations. This does become noticeable on smaller scales (see Brownian motion).
