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.
idk im a physics dweeb and we kinda already knew about this, they just proved it with a different methodology. i guess the real hype thing is it gives them a slightly better avenue to detect supermassive black holes that are hard to see
