Is Dark Matter Hiding Aliens?

Here’s a fun cosmic hypothesis on the scale of an Olaf Stapeldon story. There are even implications for data storage:

By storing its essential data in photons, life could give itself a distributed backup system. And it could go further, manipulating new photons emitted by stars to dictate how they interact with matter. Fronts of electromagnetic radiation could be reaching across the cosmos to set in motion chains of interstellar or planetary chemistry with exquisite timing, exploiting wave interference and excitation energies in atoms and molecules.

Shane Becker - Dark Matter and the #IndieWeb

Shane gave a talk recently where he outlined his reasons for publishing on the indie web:

Most people reading this will probably have an account at most or all of these sites: Facebook, Instagram, Twitter, YouTube, Vimeo, Tumblr, Wordpress. Many also had accounts at Friendster, Tribe, MySpace, Delicious, Magnolia, Gowalla, Geocities. But no one has an account at any of those (on the second list) anymore. And all of the content that we created on those sites is gone.

All of those super emo feeling you posted to MySpace, they’re all gone. Some of the great web designers of our generation got started on Geocities. That stuff is gone forever. And sure, it was sparkling animated GIFs and neon colors. But that’s important history. Yahoo bought it, left it alone for a while, and then decided one day to turn it off.

Connections: Weak Signals

Tuesday evening saw the inaugural Connections event at 68 Middle Street, home to Clearleft. It was a rousing success—much fun was had by all.

There was a great turn-out. Normally I’d expect a fairly significant no-show rate for a free event (they’re often oversubscribed to account for this very reason), but I was amazed how many people braved the dreadful weather to come along. We greeted them all with free beer, courtesy of Clearleft.

The talks had a nice yin and yang quality to them. Honor talked about darkness. Justin talked about light. More specifically, Honor talked about dark matter and Justin talked about Solarpunk.

Honor made plentiful use of sound during her presentation. Or rather, plentiful use of electromagnetic signals converted into sound: asteroseismology from the sun; transient luminous events in the Earth’s upper atmosphere; the hailstorm as Cassini pirouettes through Saturn’s rings; subatomic particle collisions sonified. They all combined to eerie effect.

Justin’s talk was more down to Earth, despite sounding like a near-future science-fiction scenario: individuals and communities harnessing the power of the photovoltaic solar panel to achieve energy-independence.

There was a beer break between the talks and we had a joint discussion afterwards, with questions from the audience. I was leading the discussion, and to a certain extent, I played devil’s advocate to Justin’s ideas, countering his solar energy enthusiasm with nuclear energy enthusiasm—I’m on Team Thorium. (Actually, I wasn’t really playing devil’s advocate. I genuinely believe that nuclear energy is the cleanest, safest source of energy available to us and that an anti-nuclear environmentalist is a contradiction in terms—but that’s a discussion for another day.)

There was a bittersweet tinge to the evening. The first Connections event was also Honor’s last public speaking engagement in Brighton for a while. She is bidding farewell to Lighthouse Arts and winging her way to a new life in Singapore. We wish her well. We will miss her.

The evening finished with a facetious rhetorical question from the audience for Honor. It was related to the sonification of particle collisions like the ones that produced evidence for “the God particle”, the Higgs boson. “Given that the music produced is so unmusical”, went the question, “does that mean it’s proof that God doesn’t exist?”

We all had a laugh and then we all went to the pub. But I’ve been thinking about that question, and while I don’t have an answer, I do have a connection to make between both of the talks and algorithmically-generated music. Here goes…

Justin talked about the photovoltaic work done at Bell Labs. An uncle of Ray Kurzweil worked at Bell Labs and taught the young Kurzweil the basics of computer science. Soon after, Ray Kurzweil wrote his first computer program, one that analysed works of classical music and then generated its own music. Here it is.
