Theory of cosmic expansion
The idea that “the universe keeps expanding,” commonly known as the Big Bang theory, is the expansion theory of the universe.
You’ve probably heard that the universe was born from a massive explosion called the Big Bang.
The effects of that explosion are still ongoing today.
For a long time, people thought of the universe as a completely unchanging space, but research published by experts in 1948 showed that “the distances to faraway galaxies keep increasing,” and from that relative observation the conclusion that “the universe continues to expand” became widely accepted.
Auroras change color depending on altitude.
While auroras are often associated with cold countries and are a major attraction with their beautiful, curtain-like lights shimmering in the night sky, did you know that their appearance changes with altitude? The higher the altitude, the lower the atmospheric density, which affects the particles from the sun and results in different colors.
Knowing which colors appear at which locations may help you plan a journey to find your ideal aurora hues.
The Earth is not a perfect sphere.
When we think of Earth’s shape, we often picture a beautiful circle—the way it’s drawn in illustrations—so most people have that impression.
However, while Earth is round, it isn’t a perfect sphere.
Strictly speaking, it’s an “oblate spheroid,” bulging at the equator and flattened at the North and South Poles.
The reason is Earth’s rotation: the centrifugal force causes the equatorial region to bulge.
It’s a fact that helps us grasp how fast the Earth spins and what kinds of forces that rotation produces.
