1. Schrödinger’s Cat A thought experiment showing the strangeness of quantum mechanics: a cat in a sealed box is linked to a quantum event (like radioactive decay). Until observed, the system is in a superposition — the cat is both alive and dead at the same time. When you open the box, observation forces one outcome. It illustrates how weird quantum rules seem when applied to everyday objects. ⸻ 2. What Causes High Tide Tides are mainly caused by the Moon’s gravity pulling on Earth’s oceans. Water bulges out on the side facing the Moon and the opposite side, creating two high tides per day as Earth rotates. The Sun also influences tides, making them stronger (spring tides) or weaker (neap tides). ⸻ 3. Why the Earth Doesn’t Fall Into the Sun The Sun’s gravity constantly pulls Earth inward, but Earth also moves sideways very fast (about 30 km/s). This balance between falling toward the Sun and moving forward keeps Earth in orbit — like “falling around” the Sun instead of into it. ⸻ 4. Entropy Entropy measures disorder and energy spreading out. Over time, systems naturally go from order to disorder (like a messy room or coffee cooling down). The Second Law of Thermodynamics says entropy always tends to increase, which gives time its “arrow.” ⸻ 5. Why You Don’t Fall Over on a Bike You stay upright thanks to forward motion, steering corrections, and a bit of stability from spinning wheels. As you lean, your steering automatically shifts to keep your balance, and your brain constantly makes small adjustments without you noticing. ⸻ 6. Did Humans Walk on the Moon Yes — between 1969 and 1972, 12 astronauts walked on the Moon during the Apollo missions. They collected rocks, set up instruments, and left behind equipment still visible today. Multiple lines of evidence confirm the landings, and new missions (like Artemis) are preparing to return humans to the Moon.
