As space expands, how does it change?

The latest measurements of the expansion of space shows that space is expanding faster now than in the past.  Does mean that the geometry of space is becoming open rather than being flat?

Also, if new space keeps being added to the old and space itself contains energy, is the total energy being diluted or is new energy being created?  Supposedly, energy must be conserved and not created nor destroyed so matter must be being converted to energy some place.

According to some cosmologists, the accelerated expansion is being driven by so-called dark energy. Perhaps the dark energy/matter has its own distinct physics.  Particles generated by this physics cannot be detected by us.

The universe is indeed a mysterious place.
