Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.

Rules:

-- PLEASE KEEP POST TITLES INFORMATIVE --

-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --

-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --

-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today . Twitter screenshots still need to be sourced or they will be removed --

-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--

-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--

-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --

-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

Uhhh

Can someone tell me what velocity you need to launch an object at in order to reach orbit? And what accelerative forces you need in order to achieve that?

How big is this railgun? How are they handling heat from atmospheric friction? You have the same problem going up too quickly as you get coming down too quickly.

It's probably a high speed launch assist, not the entire source of escape velocity.

That sounds so funny though.

How would you even do that? Build something like a particle accelerator except it's a launching railgun the size of China?

I mean yeah why not if it means you can partially reach escape velocity with like solar powered electricity vs going the entire way 100% on burning rocket fuel
