One black hole is nice, but astrophysicists can do a lot more science with 50 of them.
Since they can’t prod actual universes as they inflate and bump into each other in the hypothetical multiverse, physicists are studying digital and physical analogs of the process.
We don’t know why the universe appears to be expanding faster than it should. New ultra-precise distance measurements have only intensified the problem.
Physicists plan to leave no stone unturned, checking whether dark matter tickles different types of detectors, nudges starlight, warms planetary cores or even lodges in rocks.
The newly-measured rate of a key nuclear fusion process from the Big Bang matches the picture of the universe 380,000 years later.
Cora Dvorkin discovered new possibilities for what dark matter could be. Now she’s devising unorthodox ways to identify it.
Subtle aberrations in the clockwork blinking of stars could become “the result of the century.” That’s if the distortions are produced by a network of giant filaments left over from the birth of the universe.
