The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the satellites we use for navigation, communication and Earth observation every day.
But you might be surprised to learn that making these measurements—using the science of geodesy—depends on tracking the locations of black holes in distant galaxies.
The problem is, the scientists need to use specific frequency lanes on the radio spectrum highway to track those black holes.
And with the rise of Wi-Fi, mobile phones and satellite internet, travel on that highway is starting to look like a traffic jam.
I still think they should build out a lunar crater radio telescope out there on the dark side of the moon. The radio silence and scale would be impossible to get any other way.
That’s the far side.
Yes the far side of the moon is colloquially (and incorrectly) called the dark side of the moon. Thanks for the correction.
scale
That’s an interesting thought I hadn’t considered. The Webb is about as quiet as we’re going to get anywhere near our orbit, but a lunar compound could very easily be much larger, and would be a great deal easier to service/upgrade.
The dark side of the moon is shielded from the planet’s radio by the whole moon. So it’s a pretty attractive place to set up.
Plus, several candidate craters have favorable geometry for a massive radio telescope.
It truly is one of my favorite proposals.
I get the actual issue, but that title sounds hilariously boomer.
It’s starstink muskings up the sky.
And slowly, society began to awaken to the reality that theirs was a civilization ruled by Mammon, not men.
