Technically it's the manhole covers that need to support the weight.
Manholes themselves are expected to do the opposite of holding weight
They hold light?
Structures underground experience buoyant forces that act to push them up. Manholes (and any structure bottom, like storm inlets, pump station wet wells, etc) need special consideration since they can be partially or mostly hollow, so they have to be heavy enough to remain in place.
Right, so the light is actually pushed up by these buoyant forces and I guess that then also explains why it's so dark underground. Fascinating how learning some little new details about the world can sometimes make it all just click together!
But does that mean that light is actually hollow?
Well we know light is concentrated into comparatively tiny, but heavy points in the universe (stars), while dark fills the vast vacuum of space. So light in itself is likely denser than dark, ergo the light we have on earth must be forming hollow structures to remain lighter than dark when comparing by volume.
