3500 AD Polar reversal of the Earth

Polar reversals have occurred many times before in Earth's history - typically every 300,000 years. The last time was around 780,000 BC. This means the planet is long overdue for such an event.

From 1900 onwards, the intensity of Earth's magnetic field was known to be declining by six percent each century. By 3500, the poles are beginning to completely reverse.*

Charged particles from the Sun affect satellites and other near-Earth vessels which lack adequate protection. However, plants and animals on Earth are unaffected. During the reversal, the solar wind induces a sufficient magnetic field in the ionosphere, temporarily shielding the surface in the absence of the normal magnetic field.*

The Grand Unification Energy is witnessed
The first particle accelerators were small, terrestrial-based devices. In the early 21st century, they resulted in energies of only a few tera-electronvolts. By the middle of the 4th millenium, however, an accelerator covering the entire perimeter of our Solar System has been built. This becomes the single largest experiment in history – powerful enough to accelerate particles to a state known as the Grand Unification Energy, allowing the very earliest moments of the Universe to be simulated. The electromagnetic, weak and strong nuclear force (three of the four fundamental forces) are viewed for the first time at precisely the same strength: becoming effectively different aspects of a single force. Quarks and electrons, too, become the same, achieving another unification.*
