Note #15043

My hardware engineering is a little rusty, @ComputerHistory, but wouldn’t signals propogate along this copper cable at “only” somewhere between 0.64c and 0.95c, not 1c as you claim?

Exhibit of early transatlantic telegraph cable with message implying that it enabled "speed of light" communications.
