The Universe is Hostile to Computers

TL;DR

Cosmic rays, high-energy particles from space, can cause bit flips in computer systems and have various effects, from altering election results to glitching video games.

Transcript

A plane plummets out of the sky, a speed runner inexplicably jumps to a higher platform. What the? What the?! And an election recount is triggered. All because of the same invisible phenomenon that permeates the universe. On May 18th, 2003, voters in Belgium went to the polls. In many regions, voting was done on a computer, something the Belgians h... Read More

Key Insights

• 🎮 Bit flips caused by cosmic rays can have diverse effects, from election recount triggers to glitches in video games.
• 👾 Cosmic rays are energetic particles from space, predominantly protons and helium nuclei.
• 🥺 Cosmic rays can trigger bit flips by ionizing atoms in electronic components, such as transistors, leading to errors in binary data representation.
• 🛰️ Measures have been taken to protect critical systems, like supercomputers and space probes, from cosmic ray-induced bit flips, but complete prevention is challenging.
• 🖐️ Cosmic rays may have played a role in genetic variations through the flipping of bits in living organisms' genetic codes.
• 🙌 Understanding the origin and behavior of cosmic rays requires ongoing research and problem-solving skills.

Questions & Answers

Q: How did cosmic rays cause a candidate to receive 4,096 extra votes in the Belgium election?

Cosmic rays can flip bits in computer systems, and in this case, a cosmic ray struck a transistor, causing a bit flip that changed the candidate's vote tally.

Q: Can cosmic rays affect video games?

Yes, cosmic rays can cause glitches in video games. In the case of Super Mario 64, a cosmic ray may have flipped a bit that resulted in an up warp glitch, although this is difficult to replicate.

Q: Can cosmic rays cause crashes in computer systems and cars?

Yes, cosmic rays can cause crashes in supercomputers and have been suggested as a possible cause of unintended acceleration in cars. However, other factors, such as hardware or software issues, are usually responsible.

Q: How are critical systems protected from cosmic ray-induced bit flips?

Critical systems, such as those on Mars rovers, are designed to withstand higher levels of radiation. Radiation-hardened components and redundancy measures, like duplicate computers, are implemented to minimize the impact of bit flips.

Summary & Key Takeaways

• In the 2003 Belgium election, a candidate received 4,096 extra votes due to a bit flip caused by cosmic rays, resulting in a recount.

• Cosmic rays, energetic particles from space, can flip bits in computer systems, leading to errors and glitches, such as the unexplained up warp in Super Mario 64.

• Cosmic rays have caused crashes of supercomputers and have been implicated in unintended acceleration in cars, but measures are taken to protect critical systems, such as in Mars rovers.
