If Gravitons Exist, this Experiment Might Find Them
There are four fundamental forces in the Universe; strong, weak, electromagnetic and gravity. Quantum theory explains three of the four through the interaction of particles but science has yet to discover a corresponding particle for gravity. Known as the ‘graviton’, the hypothetical gravity particle is thought to constitute gravitational waves but it hasn’t been detected in gravity wave detector. A new experiment hopes to change that using an acoustic resonator to identify individual gravitons and confirm their existence.
SpaceX's Falcon 9 rocket can return to flight, FAA says
SpaceX can resume flying its workhorse Falcon 9 rocket, the U.S. Federal Aviation Administration announced this evening (Aug. 30), two days after a landing failure grounded the vehicle.
No, NASA's DART asteroid impact probably won't spark meteor showers on Earth — but maybe on Mars
Slower moving particles blasted out by the DART impact on the asteroid Dimorphos could create meteor showers on Mars — but it's unlikely they'll cause meteor showers over Earth.

A New Test Proves How to Make the Event Horizon Telescope Even Better
Want a clear view of a supermassive black hole’s environment? It’s an incredible observational challenge. The extreme gravity bends light as it passes through and blurs the details of the event horizon, the region closest to the black hole. Astronomers using the Event Horizon Telescope (EHT) just conducted test observations aimed at “deblurring” that view.
