How to Build a Dyson Swarm (2017)
- PaulHoule 7y agoDismantling a planet is very different from dismantling an asteroid. The energy involved is so vast, for one thing, that temperatures will get absurdly high at the surface. (And once you dig down far enough you'll find that internal temperature are hot enough to destroy any equipment you want to put on the surface.) The time scale for a planet to cool off is in the 10's of millions of years so the realistic time to disassemble a planet is long enough to colonize the galaxy some other way.
