Elon Musk’s Starlink could make Earth visible to alien civilizations
>The paper–titled “From the SpaceX Starlink megaconstellation to the search for Type-I civilizations” and written by Zaza Osmanov, a professor in astrophysics at the Free University of Tbilisi, Georgia–notes that Starlink’s massive size could give Earth its first “techno-signature” that’s actually visible from deep space.
>A techno-signature is evidence for the use of technology or industrial activity in other parts of the Universe, which could be a good way to confirm the presence of an advanced civilization.
>Osmanov estimates that ultimately, Starlink could be visible to instruments like the VLT on planets up to 260 light-years away, while instruments comparable to the FAST telescope would likely be able to detect the megaconstellation as far out as 520 light-years away. This would require Starlink to be fully ramped, of course, which would likely take a considerable amount of time.
>The idea of humans creating a megastructure invokes ideas such as the Kardashev Scale, a measure of how technologically advanced a civilization is based on how much energy it’s able to harness. According to the Kardashev Scale, a Type-1 Civilization could harness all the energy that falls on a planet from its parent star, a Type-2 civilization can harness all the energy produced by its parent star (through systems like a Dyson sphere), and a Type-3 civilization can harness the total energy in a galaxy.
>Osmanov notes that humans, at least for now, could be considered as a Type-0.7 civilization. Though considering Elon Musk’s ventures such as Tesla and SpaceX, as well as Starlink’s potential future as a megastructure that gives Earth its first techno-signature, perhaps humans are on a path to becoming a Type-1 civilization after all.
