What is the Canvas That Earth And Space Are On?

What is the structure or canvas that all the matter and energy are on?
What I mean is between Earth and The Sun is a near vacuum of Space. So what is the vacuum on? How can you have light years of distance and nothing be on it. What is the actual structure that the vacuum is I do not mean the dark matter, matter, atoms, space dust, plasma, planets, moons, asteroids. I mean what is the fundamental structure that the dark matter, matter, atoms, space dust, planets, moons, asteroids lie on. For example there are thousands of miles on the Earth's atmosphere circumnavigating the Earth. What is the atmosphere on? Like imagine the dark matter, vacuum, matter atoms, space dust, gas, water, planets, moons, asteroids are the paint or drawings on a canvas. What is the actual canvas made of?
Please understand I am talking about what matter, energy, and dark matter are on. What is the canvas we are drawn on made of?
I mean what is the actual basic structure of the universe that means if you travelled 1000 miles on earth or 1000 miles in the vacuum of space you would have covered the same distance? Yes Space is a near vacuum. But the point is you travelled the same distance in the near vacuum of space , as in travelling on Earth. So what is the basic structure that the Earth with all it's matter and near vacuum of space is on? I do not mean energy, or matter or dust. I mean what is the canvas the matter, dark matter and vacuum painted on?
