- A physicist came up with a way that could be used to test quantum gravity even with relatively weak accelerators that could be built in the near future. http://prl.aps.org/abstract/prl/v109/i14/e141103 8 comments science
- Scientists captured the smallest measurement of gravity on record. Experiment shows that Newton’s law of gravity holds even for two masses as small as about 90 milligrams. The findings take us a step nearer to measuring gravitational fields that are so weak that they could enter the quantum regime. https://www.nature.com/articles/d41586-021-00591-1 417 comments science
- Hungarian physicists think they've discovered a 5th fundamental force of nature, adding to gravity, electromagnetism, and the weak and strong nuclear forces. If confirmed, some think the new force could move physics closer to a grand unified theory of the universe, or even help explain dark matter. https://astronomy.com/news/2020/03/the-fifth-force-what-is-it 11 comments worldnews

- Most researchers think dark matter is composed of a type of particle that interacts very weakly at best with all the known forces of the universe save gravity. Now, some researchers suggest a new kind of dark matter could exist, representing about 1/5th of all dark matter in the universe. http://www.space.com/21508-dark-matter-atoms-disks.html 57 comments science
- The electromagnetic quantum vacuum makes a contribution to the inertial reaction force on an accelerated object and to the gravitational force. Gravity may be a secondary force from Weak, Strong and Electromagnetic Quantum Vaccum in Space http://arxiv.org/abs/gr-qc/0504061 4 comments science
