The Hunt–Lyra Challenge is STILL open. This publication invites scientists or anyone of any background that can use a calculator and draw a graph —professional, academic, and independent—to attempt the first independent verification of the Hunt–Lyra Informational Luminosity Law (ILL): a proposed universal law linking stellar luminosity and temperature to measurable informational output. The downloadable Replication Sheet and How To Guide contains: A simple, step-by-step method All required constants Worked examples A 25-star table example to complete Clear instructions on how to submit your results Your task: Choose any 25 stars. Obtain luminosity and temperature from any reputable source. Apply the ILL. Compare your constant with the theoretical value. The first researcher to independently verify the law with real observational data will be officially named as the verifier in the forthcoming confirmation publication announcing the ILL. This is a rare moment in modern physics: the opportunity to independently confirm a potentially new universal law. All are welcome to participate. This is an hours work, for a fantastic opportunity. The challenge begins now.
