NASA astrophysicists said that measurements of X-rays from twenty-six galaxy clusters confirmed that dark energy, a kind of mysterious repulsive gravity, dominates the universe, though scientists participating in the “Cryogenic Dark Matter Search II” admitted that even their most sensitive experiments had failed to detect a single dark-matter particle.
