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

The 365 Days of Astronomy

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.
