Yes, I saw an article a few years ago a back of the envelope estimate that suggested this would be doable if one could turn mass on the moon more or less directly to energy and use the moon as a gravitational tug to slowly move Earth out of the way. You can change mass almost directly into energy by feeding the mass into a few smallish blackholes.
How do they propose to move the blackholes? Nothing can touch a blackhole, right?
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
