Well the gravitational waves come from a mass that is moving. It's like electromagnetic waves are created by a moving charge. But because gravity is so weak you need it to be a very big mass moving very fast to be detectable. When black holes merge they spiral in and at the last moment they get to extremely high RPM with all that mass moving very fast.

Kind of an interesting thought but I don't know if it really counts to say that the mass and location of the black hole is really "information from inside the horizon" even though technically the center of mass is inside the horizon.

It stands for Laser Interferometer Gravitational Wave Observatory!

The black holes are so big and fast when they spiral in and merge that they literally create waves in spacetime which change the length of things by a tiny amount as they pass by us and LIGO is able to measure when the two arms of it change length by nanometers and that's where we got the signal.

There's also The Event Horizon Telescope which made radio images of the black hole at the center of our galaxy. We haven't been able to catch a merger with this though.

Black holes merge. It doesn't matter what size they are. It's not that the bigger one eats the smaller one they just merge.

There's different kinds of backups. For this you don't need off-site storage.

For this I set up zfs auto snapshotting which means when I delete stuff it isn't really deleted because a snapshot is still pointing at it until it rolls off the time window.

Both zfs and btrfs can do this but you do need to change the filesystem to use these which can be a lot of work.

It's disappointing that they didn't hardcode it to 11/10

We need a website where you can pay people to delete their twitter

As far as I know it was started by the original lemmy developers which made the software because they felt persecuted for their beliefs on normie social media. Lemmy just happened to be around when the reddit CEO decided to f up reddit so everyone started using it despite the creators not being well adjusted people.

Edit: just so I'm not misinforming here's what they said themselves about the origin https://lemmy.ml/post/70319

I don't get how extremist leftist content ends up attracting people who are against woke stuff in stardew really but over time I've gotten the vibe the ml and hexbear people are in general more combative and angry about things.

Please don't post old articles. You had me worried.

Why not just host on v4 and v6 from home?

LastPass said the exact same thing. I won't be a big target like they will though.

I think the main thing for not messing it up is just make sure you keep it updated. Probably set up auto updates and auto backups.
