Very nice video, because this explains the concept of parallax from the very, very beginning. This is what I like. On a sidenote - if you want to write a sci fi story about a very uptight / correct / lawful scientist or something, he could say things like "we need to cross the distance of 4.503 parallax arc-seconds" or so. Would give this dude some colour, some old fashioned colour, if you know what I mean. Some retrofuturistics.

AU was historically important because before the astronomers were able to measure the AU, they had to deal with relative distances within the solar systems. These relative distances were much easier to measure than to relate them to the distances on the earth. So for a while they worked with AU and doing precise measurements and calculations not knowing it’s value in other units all that well. Same goes for the parsec.

30 AU to Neptune. 276,264 AU to the nearest star. The transition to using LY (4.37 LY to the nearest star) seems all the more necessary. But we get back to using incomprehensible millions and even billions, even using LY or PC as our unit of distance, on the scale of the observable universe. Even our "local group" of galaxies is 10,000,000 LY or 3,000,000 PC across, which is about 100 times the diameter of our own galaxy, the Milky Way.

The gaia mission (ESA) can measure parallaxes up to tens of micro-arcseconds. However, the conversion from parallaxes to distances is not as simple as 1/p due to the errors. It requires a more complex statistical analysis.

1. The term AU (Astronomical Unit) is quite vague and unintuitive. There should be a better name for such a unit. Because it is the average distance between the sun and the Earth we could call it SED (Sun-Earth Distance). 2. Even parsec is not an appropriate unit of distance when talking for example about the distance between galaxies or the size of the observable universe. Light-year is still preferable to parsec, because light-year not only refers to the distance but the time it takes for light to travel that distance. Inside the Milky-Way Galaxy we could use the distance between the sun and the center of the galaxy as an unit. Let's call this unit COW! Or MOO! If you can have an unit called AU, why not have have one called MOO?

If youre racing someone.... from the same point, to the same destination.... but your race isnt through space, but through time instead; i.e. a temporal destination.... then it makes sense youd be competing for shortest distance, rather than for shortest time, as you normally would in a race through normal space. Proof star wars has time travel.
