What if the universe could be understood like a machine?

Alien Physics takes readers on a journey through comets, moons, black holes, and Martian mysteries-seen not through the eyes of an astronomer, but through those of a jet-engine engineer.

Allan Callweld, aerospace engineer and former jet-engine designer, grew up fascinated by the night sky. Decades later, after a career in Rolls-Royce, GE Aviation, and Safran, he brings that same engineer's instinct to the cosmos. To him, the universe is not abstract-it's a system. A place where plumes behave like exhaust streams, where instabilities mirror compressor surge, and where catastrophic stellar events echo the failures engineers fear most.

Inside, you'll discover:

• Why an interstellar comet resembles foreign object debris in an engine test cell

• How lunar cycles affect mission design just like vibration cycles affect hardware life

• Why strange rocks on Mars test our diagnostic instincts the same way borescope images do

• How black holes can be read as ultimate system-level failures

Blending real aerospace logic with cosmic wonder, Alien Physics offers a unique, engineer's guide to the skies. This is not another astronomy book. It's a fresh perspective-where engineering intuition unlocks the mysteries of space.

If you've ever loved machines as much as the stars, this is the book you've been waiting for.
