Why is it so hard to go to the Moon? The curse of Newtonian Mechanics and Tsiolkovsky's Rocket Equation force us to build huge rockets to achieve any meaningful activity on the Moon. There are two strategies to hack the laws of celestial mechanics: making fuel on the Moon and using cables to climb out of the gravity well. Here we focus on the latter, which is the Moon version of the famous space elevator. The difference to an Earth elevator is - anelevator to the Moon's surface is realistic with ...

The long term survival of the human species requires that we become an interplanetary species. But we must answer two big questions: where are we going, and how do we get there? We explore what scientists know (and don’t know) about humanity’s potential future homes both inside and outside the solar system, and then we’ll dive into the technological challenges of (and potential solutions for) getting humans to and colonizing a new planet.

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 ...
