What In The World

The Earth's rotation will experience a slight increase in speed on July 9, July 22, and August 5, resulting in each day being approximately 1.5 milliseconds shorter. This adjustment, influenced by lunar gravitational forces, might cause a negative leap second by 2029. Although this change is too subtle to notice, it could affect highly accurate systems like GPS and atomic timekeeping devices.

Researchers have identified a previously unseen quasicrystal within red trinitite, a glass that resulted from the Trinity nuclear test in 1945. This quasicrystal features a non-repeating atomic arrangement of silicon, copper, calcium, and iron, challenging conventional crystallography and illustrating the formation of materials under extreme circumstances. As the earliest human-made quasicrystal, it emphasizes how cataclysmic events, such as nuclear detonations and meteor strikes, can lead to the development of extraordinary substances, enhancing our comprehension of what matter can become.
