I have it on good authority that the sun, no longer exists. The whole purpose of Star Wars was to allow a combined US/USSR space project to be launched, without the majority of the world population knowing, to create an artificial power source in orbit to mimic the effects of the sun on our planet.
Alas, the best they could do with 70s and 80s technology was to find something that would run on diesel. Which is why peak oil is suddenly such a problem. We’re running out of fuel for our sun. And that’s why I support any, and all, high energy physics research - if we can’t turn the real sun back on before we run out of oil, we’re all going to be corpsicles.
