Earth's magnetic field creates the Van Allen belts, which trap vast amounts of radiation. When the first satellites passed through, the radiation was so high it saturated the Geiger counters, causing them to stop clicking entirely, which initially and incorrectly suggested a complete absence of radiation.

Proposed solutions to satellite streaks in astronomical images, such as data sharing and dimmer paint, are insufficient to solve the problem. These fixes cannot keep pace with the exponential growth in the number of satellites planned for launch. The only viable long-term solution—launching telescopes into much higher orbits—is prohibitively complex and expensive.

To combat the growing problem of space junk, any new satellite launched into orbit must have a pre-approved plan for its disposal. This "deorbit plan" functions like an entry visa with a set departure date, ensuring the satellite will re-enter the atmosphere and burn up after its useful life instead of becoming permanent debris.

While space offers abundant solar power, the common belief that cooling is "free" is a misconception. Dissipating processor heat is extremely difficult in a vacuum without a medium for convection, making it a significant material science and physics problem, not a simple passive process.

Contrary to popular imagery, spent nuclear fuel is a solid that is initially stored in deep pools of water. Water is such an effective radiation shield that trained divers can safely swim in the pools for maintenance. This highlights the managed safety of nuclear waste.

The significant risk that coronal mass ejections (CMEs) pose to our electron-based infrastructure—shorting out grids, satellites, and computers—is a fundamental vulnerability. This existential threat could be a major long-term driver for the development and adoption of photon-based computing, which would be immune to such geomagnetic disturbances.

Fears that the Large Hadron Collider could create a world-ending black hole were mitigated by a simple astronomical observation: Earth is constantly bombarded by cosmic rays creating collisions with far greater energy than the LHC can produce. Since the planet has survived billions of years of these natural, high-energy events, the risk from the collider was deemed negligible.

Cooling data centers in space is more manageable than on Earth. Earth’s environment is unpredictable (temperature, humidity, weather). In orbit, you can choose a consistent thermal environment, sunshade cycle, and radiation angle, making the entire system programmable and stable.

In Gabon, ancient uranium deposits naturally initiated and sustained nuclear fission for millions of years, activated by rainwater. This discovery proves that fission is a natural phenomenon, not just a human invention, challenging perceptions of it as "unnatural."

Space telescopes were designed to overcome atmospheric distortion, but they are now threatened by the explosive growth of satellite mega-constellations like Starlink. The light pollution from tens of thousands of low-orbit objects is beginning to contaminate a majority of images, undermining the effectiveness of humanity's most advanced astronomical tools.

The Chernobyl nuclear disaster was only discovered by the West because an unusual southeasterly wind blew radiation toward Sweden. Had the wind blown in its normal direction, the Soviets might have concealed the incident indefinitely, potentially altering the timeline for the collapse of the USSR, which followed five years later.
