First Results from DESI Make the Most Precise Measurement of Our Expanding Universe
Wish I had some 3D glasses!
DESI mapped galaxies and quasars with unprecedented detail, creating the largest 3D map of the universe ever made and measuring how fast the universe expanded over 11 billion years.
This is the first time that scientists have measured the expansion history of that distant period (8-11 billion years ago) with a precision of better than 1%, providing a powerful way to study dark energy.
With just its first year of data, DESI has surpassed all previous 3D spectroscopic maps combined and confirmed the basics of our best model of the universe – with some tantalizing areas to explore with more data.
