Of all the unanswered questions in modern science, perhaps the most talked about is whether we are alone in the Universe. A new paper looks at another way we can detect advanced civilizations, and at its heart is the need for energy! The more advanced a civilization becomes, the greater its need for energy, and one of the most efficient ways, according to current theories, is to harness the energy of an actively feeding black hole. The paper suggests that a civilization feeding matter into a black hole could harvest energy from it, and perhaps most excitingly, the process could be detectable from 17,000 light years away! The search for intelligent life beyond Earth has fascinated scientists, philosophers, and even inspired artists for centuries. With hundreds of millions of stars in our galaxy and billions of other galaxies throughout the cosmos, it seems that the odds are in our favor to find other civilizations out there. The discovery of thousands of exoplanets in recent decades adds to the excitement, so researchers have turned radio telescopes and space probes to the search for aliens. Projects such as SETI, the Search for Extraterrestrial Intelligence, have scanned the sky for unusual patterns or messages that might reveal an advanced civilization, but despite the effort, there has been a distinct lack of success, as of yet. A different approach is to look for advanced civilizations based on their energy signatures. It’s a novel idea that seeks to identify civilizations based on artificial patterns in the electromagnetic spectrum. We’ve certainly seen how human energy demands have increased as we’ve become more advanced, and so theoretically any more advanced civilizations would need to harness energy on a scale far beyond what we currently do. It could be that civilizations use giant megastructures like Dyson spheres to harness energy from stars, and it’s their output or impact on a star’s light that might be detectable. In a paper written by Shant Baghram and published in the Astrophysical Journal, the team begins by categorizing civilizations on the Kardashev Scale. They categorize advanced civilizations by measuring their technological advancement based on the amount of energy they are able to harness and use. They also propose an alternative scale based on the Kardashev scale and the distance a civilization is able to explore space, suggesting that more advanced civilizations can explore further from their host planet. As a paper based purely on a theoretical model, they take the category of advanced civilizations and explore the idea that they could use Dyson spheres around primordial black holes as an energy source. The team also proposes observational techniques that could be employed to detect such structures using infrared and submillimeter signatures. They state, however, that telescopes such as ALMA (Atacama Large Millimetre/Sub-millimetre Array) are well-positioned to make observations and even detect signatures and perhaps even megastructures at distances of approximately 5.4 kiloparsecs (178 light-years).
