They’re skipping the collection of underpants and going straight to step 3, profit.
(It’s venture capital.)

In a major discovery, scientists say space-time churns like a choppy sea The claim of a gravitational wave background suggests the universe is constantly roiled by violent events that happened over the past 13 billion years.

What's a pulsar timing array? How do you detect gravitational waves with that? Obviously I'm biased, but I think you could do worse than watch this talk I gave a few years ago. https://youtu.be/taeABpFjjQg You might even enjoy it!

On June 29th, we in the North American Nanohertz Observatory for Gravitational waves (NANOGrav) are announcing our results. The culmination of 15 years' work! The Australian (Parkes), European + Indian, and Chinese Pulsar Timing Arrays are also releasing their independent results on the same day.

A Bernedoodle (Bernese mountain dog - poodle mix). Both his parents were Bernedoodles. We needed a low-allergy dog but were warned off poodles as typically more high-strung.

Quality canine content? Sure, here’s more Rocket. (Am I supposed to tag @darthbluesky.bsky.social for posts like this?)

It's a real shame. But that site is no longer usable for science stories, I think.

The NANOGrav collaboration has a big announcement coming up - people in our collaboration might already be talking to you about it.

Oof. Can't argue, but bad timing for us... :(
