Hollow core vs solid core wood doors

What exactly distinguishes a hollow core from a solid core wooden door? I understand that the former would be, well, more hollow, but at what point would a solid door become 'hollow' in terms of wood matter or density?

"This one has a sting in the tail , a wood pulp honeycomb same as bees and wasps make mostly air but not ' hollow ' . Rigid and lightweight core known often as egg box ' doors is the answer.
Solid cores can be either a composite of chipboard framed with outer edge timber or from all wood strip and block off cuts glued together .
All have a laminate printed or real wood veneer outer layer and matching timber foredge side trims to give the appearance of solid hardwood , but less expensive ."

"Hollow core doors are what they say, basically very light weight, inside the door is a Honey Comb shape made of cardboard/hardboard, these doors have a Lock Block which is a piece of timber in the middle so you can fit a lock and handle. They are cheaper than solid doors too.
Solid doors are same again Solid, they would normally be a fire door FD 30/60 that’s the amount of minutes they are fire rated too. Hope that helps."
