A new method for detecting life assesses not specific substances, but the chemical diversity of a sample.

If your soup has a thousand different ingredients floating in it, it was probably made by a living cook, not a machine. It seems life always creates chemical diversity, while lifeless nature creates uniformity. Scientists suggest searching for aliens this way: not for specific molecules, but for a rich mixture. This could work even for life that is completely unlike ours.

🎯 The method works remotely: just spectral analysis of light reflected from the planet.

🎬 This echoes the idea from the movie 'Contact': the intelligent signal was distinguished by its complex structure, not random noise. Similarly, life reveals itself through molecular polyphony.
