Here's a list of cosmic catastrophes that are beyond human control:

1. Gamma-Ray Bursts (GRBs):
   - Description: Extremely energetic explosions in distant galaxies, emitting gamma rays. If a GRB were to occur close enough and its beam directed towards Earth, it could potentially deplete the ozone layer, leading to mass extinctions.

2. Supernova Explosions:
   - Description: The explosion of a star at the end of its life cycle. If a nearby star (within about 30 light-years) were to go supernova, the radiation could strip away Earth's ozone layer, exposing life to harmful UV radiation, potentially causing mass extinctions.

3. Asteroid or Comet Impacts:
   - Description: Large celestial bodies colliding with Earth. An impact from an asteroid or comet greater than about 1 km in diameter could cause global devastation, including climate change, tsunamis, and mass extinctions.

4. Solar Flares and Coronal Mass Ejections (CMEs):
   - Description: Powerful eruptions from the Sun's surface. While Earth's magnetic field usually protects us, an exceptionally strong solar flare or CME could overload our atmosphere and magnetosphere, potentially damaging satellites, disrupting communications, and even affecting power grids on a global scale.

5. Hypernovae:
   - Description: A more extreme version of a supernova, occurring when very massive stars collapse. These events are rarer but could have even more devastating effects if close enough to Earth, similar to but potentially more severe than a supernova.

6. Black Hole Encounters:
   - Description: If our solar system were to pass close to a rogue black hole or if one were to form unexpectedly nearby, the gravitational effects could disrupt planetary orbits or even pull Earth into the black hole, leading to unimaginable destruction.

7. Galactic Collisions:
   - Description: Our Milky Way galaxy is on course to collide with the Andromeda galaxy in about 4 billion years. While such events are spread over vast timescales and distances, they could reshape our galaxy, potentially affecting the solar system's stability.

8. Cosmic Rays:
   - Description: High-energy particles from outside the solar system. While Earth's atmosphere generally shields us, an unexpected increase in cosmic ray flux due to changes in the local interstellar medium or solar activity could pose risks if the atmospheric protection were significantly reduced.

9. Dark Energy Expansion:
   - Description: If dark energy accelerates the expansion of the universe more than expected, it could eventually lead to the "Big Rip" scenario where everything from galaxies to atoms could be torn apart, though this is on a timescale billions of years into the future.

10. Vacuum Decay:
    - Description: A hypothetical event where a bubble of true vacuum could expand at the speed of light through space, changing the fundamental constants of physics, potentially wiping out everything in its path. This is extremely speculative and based on theories about the stability of our current vacuum state.

Each of these events, while largely theoretical in terms of their impact on Earth specifically, represents potential cosmic threats that are beyond our current technological capabilities to prevent or mitigate.
