Scientists are one step closer to uncovering the 'true nature' of dark energy

Five thousand robots will soon work together to create a 3D map that highlights 35 million distant worlds. Called Dark Energy Spectroscopic Instrument (DESI), this project is set to build 5,000 finger-width, 10-inch-long cylindrical robots which will gather light from galaxies, stars and quasars. This data will help experts learn about the nature of dark energy and provide a glimpse of what the universe was like 11 billion years ago.
