Marble Phantasm is the ability to reshape the world according to the user's thoughts. It's literally "I can do anything, please understand". Arc can not only control the elements and natural phenomena, spring forth money, chains and whiteboards out of nothing, she can also create textures, which are layers of reality with their own rules and concepts, and she can also store them, stripping the layers away like melted paint.
Also, like the other anon said>>43310581
The stuff she does in that scene with Roa was overwritting the human texture/universe with her own universe. The human laws of physics that have been present in the world itself for thousands of years can be overwrritten by her.
That's why Arc is referred to as the "canopy covering the void (cosmos)" by Roa, as an aspect of Arc herself is covering the cosmos. This is shown in the Celestial Conception scene in Ciel's route where it's explicitly shown and stated the texture of the planet dwarfs the human universe of awareness, and it's laws are far beyond human understanding. This is also why Roa's goal is stated to have the cosmos unveiled.
It basically means that Arcueid's power encompases the cosmos and can rewrite reality far beyond the reach of human order.
