Simultaneity

[mmcirvin]

Measured in the heliocentric frame, the time to the Galileo probe's destruction is now less than the light-speed travel time between Earth and Jupiter. What that implies is that, according to special relativity, there are some inertial rest frames (corresponding to motion at a large fraction of the speed of light in the direction of Jupiter) in which Galileo is already gone as I write this, and others in which it still exists.
