Apple, for the first time opened the gates of its new campus in California and welcomed the media at the Steve Jobs Theatre. I looked at the photos and more than the iPhone X, what excited me was the way glass walls hold the ceiling high up without any support in the center.

What wizardry is going on there? Can someone explain?

The roof is actually a hollow double dish construction that is quite stable with only circumferential support. Glass has enormous compressive strength and can take the load. The glass walls are on earthquake proof supports.
This is only the foyer. The actual theatre is below ground level.

Well, I'm assuming it's steel that forms the majority of the roof. Is there any limitation on how big can we go with such a design?

There are dome roofs up to 140m, though the structural elements may differ from the Steve Jobs Theatre.
