Less dense than helium would immediately rise ot the ceiling unless the picture is taken in a vacuum.

From article above : "A graphene aerogel that is seven times lighter than air, and 12% lighter than the previous record holder (aerographite)." so wtf. It would float on air (like heliumballoon) if it's lighter than air..

Well it's lighter if in amount, thou whats the density?

If the material is strong enough to withstand air pressure, it would float when made with vacuum bubbles inside => lighter than air. Most aerogels are quite fragile, though.

They probably forgot to mentoin that it's full of air. Kinda like a balloon is lighter than air when large enough... If you substract the air inside. Typical news site click bait title. Cool material though.
