b'Science\\u2026?! \\n\\n

Some things are more art than science sometimes.

\\n\\n Structures anchored to geostationary orbit \\n\\n

\\u201cSpace antennas\\u201d but what kind of signal would benefit from this design? X-Rays? Why would this not be better off in orbit? The structure sure looks a lot like a space elevator. Space elevators and geostationary orbital masses.

\\n\\n Falling from space \\n\\n

It\\u2019s hard to steer without sufficient atmospheric density. Felix Baumgartner\\u2019s jump \\u201cfrom space.\\u201d

\\n\\n High energy blasting \\n\\n

Antimatter nonsense. Our increasing fragility in the face of an unlucky coronal mass ejection. Protecting infrastructure both inside and increasingly outside our atmosphere.

\\n\\n Moon settlement \\n\\n

Moon surface settlements vs moon gateways vs embarking to The Moon from low Earth orbit. Awesome moon buggy chases. Pirates!

\\n\\n Mars settlement \\n\\n

Communicating with and from Mars. Interplanetary distance and comms speed. Building settlements within Martian or Lunar lava tubes.

\\n\\n The heliopause \\n\\n

Finding the \\u201cedge\\u201d of our star system. Difference in concentration of high energy particles.

\\n\\n SETI \\n\\n

Looking for signs of life around other stars. Taking pictures of black holes. Planet-sized telescopes. The absurd distances from Earth to other stars. Vegemite in Australia. Absent of evidence is not evidence of absence.

\\n\\n Nuclear spaceships \\n\\n

Project Orion. Blowing up your spaceship because it doesn\\u2019t have a nuclear bomb-ready push plate.

\\n\\n\\nSupport the show!'
