Black holes could make the sun jiggle, nanodiamonds' origin and more in this week's news

Black hole sun
An asteroid-sized black hole passing through the sun would ring it like a clapper striking a bell, according to new computer simulations. Existing telescopes would be able to spot this ripple of energy, providing a new way to look for hypothetical black holes created just after the Big Bang. These entities could be part of the hidden dark matter thought to make up most of the universe’s matter. But since such black holes would be rare, passing through the sun once every 10 million years or so, testing this idea would require new telescopes monitoring millions of stars, researchers in New York and Germany report in the Sept. 9 Physical Review Letters.
