Ask HN: Telescope as a Window to Our Past
2 by ram1981 | 2 comments on Hacker News.
This is for the physics nerds out there. If Hubble telescope can see a past event of a distant planet, can the earth’s past be seen by a Hubble telescope placed in a distant planet? The answer is most likely yes. So my follow up. What if there is a mirror like object on that planet that reflected the light back onto earth? Can Hubble then become a window to our past? And can we essentially manoeuvre Hubble to pick up past events “live”? It’s almost like having a drone above us but feeding us images from the past. Sorry about the long question :(

Just as with my phone number and email

Ask HN: Why can't the US government run their own social media? 2 by rglullis | 2 comments on Hacker News. 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
