Yeah I got distracted with draft stuff!

Physicists Have Detected The Background Hum of The Universe

Teams in Australia, the US, Europe, China, and India are releasing their results simultaneously in a slew of papers.

"We've been on a mission for the last 15 years to find a low-pitch hum of gravitational waves resounding throughout the Universe and washing through our galaxy to warp space-time in a measurable way," astrophysicist Stephen Taylor of Vanderbilt University and chair of NANOGrav, the team in the US, said in a press briefing.

"We're very happy to announce that our hard work has paid off, and … we have exciting evidence of this background of gravitational waves."
………
NANOGrav's signal has a confidence level of 4 sigma across 67 pulsars, or 99.349 percent. The PPTA's signal has a lower confidence level because it studied fewer pulsars; their detection is based on just 30 stars but over a longer period. The gold standard for a discovery is 5 sigma. So there's still a lot of work to be done.

And the neutrino announcement: https://www.reuters.com/technology/s...ay-2023-06-29/

Our home galaxy, however, is now being observed for the first time in a brand new way.

Scientists said on Thursday they have produced an image of the Milky Way not based on electromagnetic radiation - light - but on ghostly subatomic particles called neutrinos. They detected high-energy neutrinos in pristine ice deep below Antarctica's surface, then traced their source back to locations in the Milky Way - the first time these particles have been observed arising from our galaxy.
