| The Issue Simplified (with apologies to the cosmological community)
Several decades ago it was determined that the universe is expanding.
More recently, it has been determined that the rate of that expansion is accelerating.
No one yet understands the mechanism that is causing that acceleration.
One theory is that some "dark energy" which we cannot yet see nor measure, may be that mechanism.
The HETDEX will examine two million galaxies to map how fast galaxies are moving away from us as a basis to attempt to understand what this "dark energy" may be.
As Gary Hill clearly noted in his presentation, "Dark Energy" may not be dark and may not be energy. But therein lies the puzzle that Gary's project will attempt to unravel.
