Chaos Computer Club - 33C3: works for me (mp3)

Imagine, there is this huge data center but your user privileges allow you to access only 5% of the data. That is the exact same situation physicists face when trying to study the cosmos. 95% of our universe is made out of something that cannot be seen or touched. We generally call this unknown substance "dark matter" / "dark energy". The recent discovery of gravitational waves gives us a handle on the dark cosmos. We can now listen to invisible events in our universe. But there may also be other methods to shed light on the dark side. about this event: https://fahrplan.events.ccc.de/congress/2016/Fahrplan/events/8245.html
