Recently, I’ve been involved in some discussions about causality, and some of those discussions have struggled to find any resolution, which I find frustrating. I don’t think people need to agree on ideas, but my experience is that usually people can agree on how to frame and talk about those ideas.
I sometimes get the feeling people are so set on disagreeing that they don’t always engage on what the other party is saying. I never know if it’s a lack of comprehension, a lack of willingness, or (on my part) a lack of communication skill or sufficient explanation.
So here are some things I think (I hope) are uncontroversial.
One of the cool things that happened in 2013 is that Voyager 1 has left our solar system. This time it was really, for sure, no kidding! There have been some previous occasions where it left, but this time we really mean it. (Truth is, it’s still way inside the Oort cloud, so in some sense it’s merely left the city for the ‘burbs.)
Say rather that Voyager 1 no longer flies in skies affected by the sun. The heliosphere, the giant fart bubble around our solar system, is filled with our sun’s gassy emissions. Outside that bubble is the galactic ass gas of a billion other suns. Voyager 1, for the first time in human history, samples farts not our own.
It got me thinking about our interstellar golden record: Earth’s Greatest Hits!
