Ask HN: Vacuum is so powerful, so why it doesn't suck the Earth's atmosphere?

I read about the experiment of Magdeburg hemispheres [1], where they attached two halves of a sphere only by emptying the sphere from air, and they couldn't pull them apart using 16 horses! So why doesn't the vacuum in outer space absorb the Earth's atmosphere if it's that powerful? The obvious answer would be gravity, but how? I mean, gravity isn't as strong as 16 horses, right?

With the news yesterday of POTUS joining threads.net and with the fanfare about the possibility of following him from other AP-compatible servers (like Mastodon), I was left wondering why is it that the White House couldn't just run their own services? Doesn't "POTUS is using threads for social media" feel a bit like "POTUS is using outlook.com for email"? Is there anything about the bureaucracy that stops their some small team to setup a Mastodon server on "social.whitehouse.gov" and make this a reality? I find it hard to believe that this would be "if it got hacked it could create diplomacy issues", because I don't think that Facebook is setting up any type of special infrastructure to deal with political figures on their platform. Also, none of this seems to be a problem for some of the EU governments. Maybe I am missin...
