Cheap Astronomy - Implausible Engineering Episode 4: Asteroids & Time Machines. Again.

Something Stupid.


Episode 4a: Space mining


Most of the contents of the periodic table are available in
atomic or molecular form across the solar


system. After all, the Earth accreted out of the same circumsolar
dust cloud that all the other planets


accreted out of, not to mention the dwarf planets, asteroids,
comets and other bits.


 


Episode 4b: Time machine (or not)


In a previous episode of Implausible Engineering we discussed how
you could shift yourself into the


future by sitting within a very, very fast moving cabin where
relativistic time dilation would come into


play.
