For more than sixty years radio telescopes have listened to the sky and found nothing. No narrowband signal, no laser pulses, no waste heat from large structures. This silence is the most consistent finding in modern astronomy. It is usually treated as an open question.
On the Gulf coast of Louisiana, a launch site is being built for thousands of launches a year. Around a hundred billion dollars, a former industrial property, an operator who spent seven years looking for the right location. The figure is impressive, but it is not the interesting part of the announcement. What is interesting is how the site is described: its own propellant production, its own power generation, a deepwater port, its own vehicle processing, probably its own airfield. A place that needs nothing it does not produce itself.
