From Branch Interferometer to Resonant Branch Coupler: The Science of Extracting Energy from Other Realities Detecting a parallel universe is one thing. Plugging into it is another entirely.  That's the escalation at the heart of First Beacon, the debut novel by Vivek Parate: the branch interferometer — the device physicist Ved Sharma builds to merely listen for the signature of a quantum branch point — gets rebuilt into something far more ambitious. A resonant branch coupler, designed not just to sense another branch of reality, but to draw power out of it.  It's worth noting that Parate isn't approaching this cold. Before writing the novel, he spent years working with industrial robots and battery systems — including designing Battery Energy Storage Systems and programming EV assembly lines. That real engineering background is exactly why the invented physics in First Beacon feels load-bearing rather than decorative: the language of energy systems, resonance, and coupling comes from someone who has actually worked with the real-world equivalents.  It's a thrilling idea for fiction, and it's also a perfect excuse to dig into some genuinely deep physics: resonance, quantum tunneling, the conservation of energy, and why "free energy from another universe" runs headfirst into some of the most bedrock laws science has. Let's break down the two-phase invention piece by piece — what's borrowed from real physics, and what's pure invention.  To know more about the first beacon @ https://www.amazon.in/First-Beacon-Vivek-Parate/dp/B0H3MC9KKR/ref=sr_1_1?crid=1WO6Z3C2SZVYZ&dib=eyJ2IjoiMSJ9.ZvDT95s_YbVglq6JoMbuZp0oJs0YajZGtUAj9EGYKZPIBGne-PkYtPGq6ZHGFM2S20gTPmmbnILYJGIngVo-RwvTrHAYpuuOXfBMywnnp-9Hscy-5GXt-p-LwHMaoLBibWQA2dxCT0m3RvEvZOfsZTamFkDNbAZ4GMbQ82tylwiUyPbmx3CSmdVoXMdy7PFapGyoxRlUGsBupNlpfAAV4Rt7Y_CqidTPKn7ovs3rxN4.pk2aMG2PwlU72ZFhnCU2lW7eJ6K1OegNLXjIUOsN88Y&dib_tag=se&keywords=first+beacon+book&qid=1785225426&sprefix=first+beacon+%2Caps%2C299&sr=8-1
