>A researcher in Russia has made more than 48 million journal articles - almost every single peer-reviewed paper every published - freely available online. And she's now refusing to shut the site down, despite a court injunction and a lawsuit from Elsevier, one of the world's biggest publishers.
>"Payment of $32 is just insane when you need to skim or read tens or hundreds of these papers to do research. I obtained these papers by pirating them," Elbakyan told Torrent Freak last year. "Everyone should have access to knowledge regardless of their income or affiliation. And that’s absolutely legal."
>journal subscriptions have become so expensive that leading universities such as Harvard and Cornell have admitted they can no longer afford them. Researchers have also taken a stand - with 15,000 scientists vowing to boycott publisher Elsevier in part for its excessive paywall fees.
>The site works in two stages. First of all when you search for a paper, Sci-Hub tries to immediately download it from fellow pirate database LibGen. If that doesn't work, Sci-Hub is able to bypass journal paywalls thanks to a range of access keys that have been donated by anonymous academics (thank you, science spies).
>This means that Sci-Hub can instantly access any paper published by the big guys, including JSTOR, Springer, Sage, and Elsevier, and deliver it to you for free within seconds. The site then automatically sends a copy of that paper to LibGen, to help share the love.

Gravitational waves, now being heralded as the greatest scientific discovery of the decade, do not bring with them some magical form of communication.
Just because some hipster egghead with a liberal arts degree decided it would be a good science word to drop in their shitty science fiction novel, doesn't mean that the practical applications of gravitational waves can be anything you want them to be.
So, let's talk about exactly what gravitational communication would mean:
First off, Gravitational waves propagate at c. This makes them no more effective a means of ultra long distance communication than actual light.
Secondly, they are very, VERY weak, and much harder to detect than light. To give you an idea of how weak they are, the "amplitude" of the gravitational waves detected at ligo, originating from 2 twenty to thirty solar mass black holes spinning around each other pretty damn fast astronomically speaking, was about 1/3rd the diameter of a proton.
To put that in perspective, pic related.
Protons are fucking miniscule.
Lastly, we have no means of creating gravitational waves at any kind of detectable level.
