Einstein's Theory of Relativity Holds True for Early Universe, 3D Map Confirms

Just over one hundred years after Albert Einstein proposed his general theory of relativity, scientists have mapped nearly 3,000 ancient galaxies to confirm its rules held true in the early universe. Researchers created a 3D map of the galaxies' positions to confirm that the effects of relativity are consistent through the life of the universe, suggesting that dark energy plays a role in the universe's expansion.
