- When two black holes spiral into each other, surprisingly the mergers can sometimes kick the final black hole away at a high enough speed to eject it from its host galaxy.A new analysis of gravitational waves from a merger provides the first direct evidence of a strong kick. https://physics.aps.org/articles/v15/s62 58 comments science
- General Relativity Withstands Double Pulsar’s Scrutiny. Sixteen years of timing data from the double pulsar confirm the validity of Einstein’s theory of general relativity to a new level and also reveals new relativistic effects that, although expected, have now been observed for the first time. https://physics.aps.org/articles/v14/173 12 comments science

- Dark Matter Alternative Passes Big Test. A cosmological model that doesn’t require dark matter has overcome a major hurdle in matching observations from the cosmic microwave (CMB), the leftover glow of the big bang. This dark-matter-free model is an extension of the so-called MOND background. https://physics.aps.org/articles/v14/143 194 comments space

- Light Pulses Change Speed in a Plasma. Interactions between two laser beams in a plasma allow for precise control over the light’s velocity. Physicists show how to adjust the speed of light in a plasma, creating an order-of-magnitude speed change of the light. https://physics.aps.org/articles/v14/s60 8 comments science
- Wormholes Open for Transport - Despite populating many science-fiction plots, wormholes have been hard to justify theoretically. Now, two separate groups present models that make wormholes seem less exotic and slightly more credible for human use . https://physics.aps.org/articles/v14/s28 693 comments space
