C = 2π r.
If r = ∞ (infinity),
The circle's circumference becomes a straight line.
I actually thought about this when I was in Year 9.
ADHD brain, haha.
If you apply this to Newton's first law of motion, which says, "An object at rest stays at rest, and an object in motion stays in motion at a constant speed in a straight line, unless an outside force acts on it," you realize that if you travel in a circle in space that has an infinite radius, you will one day come back to the same spot.

The Ezo flying squirrel (Pteromys volans orii) or Ezo-momonga (Japanese: エゾモモンガ) is a subspecies of the Siberian flying squirrel.
It is endemic to Hokkaidō, Japan, part of the region once known as Ezo.
An Indian Ringneck Parakeet (Psittacula krameri) on a Tamarind tree.
They are also known as the rose-ringed parakeets.
A medium-sized, intelligent parrot renowned for its vibrant colors, sleek long tail, and impressive ability to mimic human speech.
🚨: DNA study suggests humans nearly went extinct 900,000 years ago.
Scientists estimate that a prehistoric population bottleneck reduced human ancestors to around 1,280 breeding individuals.
Here’s a wild physics fact: 🌌
A human is actually closer in size to the entire observable universe than to the Planck length.
We’re about 1 meter tall.
⬇️ Planck scale: ~35 orders of magnitude smaller
⬆️ Observable universe: ~27 orders of magnitude larger
So on a logarithmic scale, we’re about 100 million times closer to the cosmic end than the tiniest theoretical scale.
The universe is unimaginably huge… yet we’re surprisingly close to its scale. 🤯🌌
The Mid-Autumn Festival,
also known as the Moon Festival or Mooncake Festival, is the second-most important holiday in the Chinese calendar after Chinese New Year.
It is celebrated on the 15th day of the 8th month of the traditional lunar calendar when the moon is at its brightest and fullest.
Smallpox killed an estimated 300 million to 500 million people in the 20th century alone and hundreds of millions more throughout its thousands of years of existence before "Humans" intervened.
Fennec Fox, another Saharan cutie.
Their giant, bat-like ears act as natural radiators, releasing body heat and keeping them cool. Their large ears also help them listen for small prey moving underground.
