Earth vs an Adamantium Spear the length of Jupiter's Diameter

[big_adventure]

Most of that is fair enough, and open to supposition from both directions whether we'd get stuff like nuclear shaped charges working in time. Don't think we'll get any further, really.

Interesting discussion, anyway.

Yeah, I think that we agree completely on that at least. :-) Maybe not Rake-level agreement, but definite agreement. It's all supposition because it hasn't specifically happened. Feat-based considerations (and humans obviously don't have feats for deflecting a stick like this) work pretty well for Rumbles, but this is very different.

It is an interesting discussion, and it would make an awesome XKCD kind of question.

It did get me looking up 'nuclear shaped charge' to see if we HAD figured them out yet, which brought me to information reminding me that Project Orion was a thing for a bit. *sighs*

If you haven't already bought 'What If?' by Randall Monroe of XKCD fame, I highly recommend.

I'm about 75% sure that I'm the one who initially recommended that you read that brilliant tome, several years ago in another conversation. :-) I clearly recall recommending it, I believe that you'd yet to acquire it. Around the same time you recommended "The Girl with all the Gifts" and "The Rosie Project" to me.

Fun convos in this thread. Always liked these scenario threads.

Hmm. I felt like doing math, poorly. I'd also prefer Earth survive this, so all assumptions are best case scenarios for Earth.

max earth to jupiter distance: 968000000000 m
pole speed: 16000 m/s
time to intercept: 60500000 s (not accounting for planetary movement)
radius of earth + atmosphere: 6453312 m (assuming whatever god threw this at us has good aim for a center mass hit and an atmospheric miss would be enough, which I doubt)
speed necessary to deflect from the path and miss earth if starting from the moment it was detected: .106 m/s

telephone pole radius: .11 meters (varies wildly, tapers, etc. Just need a number)
pole length: 71492000 m
pole volume: 2717644 m3
steel mass placeholder for adamantium: 7900000 g/m3
pole mass: 21469387600 kg (the tiny radius helps us a lot here)

acceleration in 1ms to reach target speed: 106 m/s2 (I'm not getting involved in impulse or whatever for this)
Force required: 2,275,755,085,600 N
This guy ( http://www.u.arizona.edu/~tuvas/Project_orion.html ) throws out a number for project orion that 1 bomb == 80,000,000 N. Assuming that number, you'd need 28,447 project orion style detonations.

Saturn V stage I force: 3.5*10^7 N
Force required to deflect: 65,021 Saturn V rockets

Bomb or rocket, you'd have to exert this force at the center of the pole to prevent it from wasting some energy tumbling.

Lacking a teleporter, there's no real way to get a fully-loaded Saturn V to the pole, position it, and fire it. Even if we could launch parts and fuel to orbit, assemble it, and somehow get it to the pole with a second ship, the time required to do so will increase the number of Saturn Vs needed to get a successful deflection. Even under the best circumstances, we're boned.

Nice maths, wahwho. Yeah, it's not getting into all of the various factors that probably exist, but for a KISS solution, it rather makes the point.

Good way to delurk.

Probably, then; my memory isn't helping, here.

Nice cocktail napkin stuff, and welcome to Rumbles!

We're screwed.

DAN is kind of a badass.

...hilariously, DAN would make a decent weapon for Jupiter Gorilla, Monkey-King style.

Swinging the thing at his max speed and strength would bust a couple of galaxies.

Love it when the math gets broken out
