Dark energy is space

[kurious]

If I double the size of a classical,non-quantum mechanical vacuum,
I double the volume of space and its density stays constant at zero
kg/ m ^3.As the amount of dark energy in the universe increases the volume of space increases and the density stays constant.Is dark energy space?

Hi kurious;

I don't think all space is dark energy. But, I think all dark energy is space.

Just my thoughts.
