The Moon is Gradually Moving Away from Earth
The Moon and Earth share a dynamic relationship. Over time, it has been discovered that the Moon is gradually moving away from our planet. This phenomenon is caused by the transfer of angular momentum from Earth’s rotation to the Moon’s orbit due to tidal forces. Approximately 3.8 billion years ago, the Moon was much closer to Earth, and its influence on our planet’s tides was significantly stronger. Currently, the Moon is receding from Earth at a rate of about 3.8 centimeters (1.5 inches) per year. While this process won’t have an immediate impact on Earth, it does have implications for the distant future, such as potentially longer days and different tidal patterns.

Buttered Toast Tends to Land Butter-Side Down When Dropped
You might be able to file this fact in your “useless information” drawer. The “buttered toast phenomenon” is a common occurrence in which people notice that when they accidentally drop a slice of buttered toast, it often lands butter-side down. This phenomenon is the result of several factors, including the height from which the toast is dropped, the angle at which it falls, and the time it takes for it to rotate. When toast falls from a typical table height, it doesn’t have enough time to complete a full rotation before it lands, leading to the buttered side facing downward. While it may seem like a peculiar observation, it’s a great example of the physics of rotation and the interplay of various forces.

In a Vacuum all Objects Fall at the Same Rate, No Matter Their Mass
Galileo Galilei’s famous experiment on the Leaning Tower of Pisa demonstrated that in a vacuum, where there is no air resistance, all objects fall at the same rate. This fundamental principle of physics means that a feather and a hammer, if dropped simultaneously in a vacuum, will hit the ground at the same time. It’s often counterintuitive because we’re accustomed to the effects of air resistance, which causes lighter objects to fall more slowly. However, in the absence of air, gravity is the sole force at play, and it affects all objects equally.
