This is fun - assuming a pair of 14ga wires were run the 14.5 billion mile distance from Earth to Voyager 1, the mass of copper would be on the order of 10<sup>12</sup> kg, or ~5 times the mass of copper ever mined out of the earth.

:Wow, that's a lot of copper! I wonder how they've been communicating with the probes up until now? :) [[User:Danny E. Corchado|Danny E. Corchado]] ([[User talk:Danny E.

At current prices for copper, this spool would cost ~9.6 trillion dollars. Surprisingly, that's only about a third of the US national debt. --[[User:KrazyKat|KrazyKat]] ([[User talk:KrazyKat|talk]]) 17:29, 25 May 2022 (UTC) | At current prices for copper, this spool would cost ~9.6 trillion dollars.

The problem of the Earth spinning could be solved by putting the contact at one of the poles; it will have to be on a swivel joint to prevent it from twisting. But there's also the Earth revolving around the Sun, which requires the cable length to cycle up and down by 186 million miles every year. I guess we could use a big version of dog leash holders.

The explanation mentions the wire going through the Sun when we're on opposite sides of the Sun. But the Voyagers aren't traveling in the ecliptic plane, so it will probably miss the Sun. Although it still might be close enough that the heat will melt it.

Is the whole joke of the "Alternate explanation" that they went overboard with the [citation needed]s?

Theoretically speaking, if the copper spool were to be anchored at the North or South Pole, it would avoid issues of wraparound.

:Now you just have to work out what happens as the conductor moves (around, but also feeds out through) the geomagnetic field. (See {{w|Electrodynamic tether}}, not sure if it would help or not to be anchored directly upon the maximum declanation point of the geomagnetic pole, which isn't ''quite'' at the axial pole for the purposes of rotation-mitigation [[Special:Contributions/172.70.85.177|172.70.85.177]] 23:44, 25 May 2022 (UTC) | :Now you just have to work out what happens as the conductor moves (around, but also feeds out through) the geomagnetic field.
