The news is out! The @NANOGrav pulsar timing array collaboration has detected a background of cosmic gravitational waves rippling through our Universe! Let’s talk about it!(Full press conference tomorrow, https://nanograv.org/news/2023Announcement)1/n

This is the announcement that was being hyped up in that aliens or time-travel thread a few days ago.

The announcement is that the scientists who were studying gravitational waves found gravitational waves. This was perhaps a bit overhyped.

To be fair, it's a very big experiment and it's nice that they got it all to work. They also found more gravitational waves than expected.
