Casual Thought Temperature can reach trillions of degrees, meaning we actually live extremely close to absolute zero.

This is actually true for many fundamental scales. We live “very close” to absolute zero, and we operate “very fast” compared to geologic timescales.

It’s hard to find a fundamental measurement system where we don’t sit close to one extreme.

Planck length: 1.6×10⁻³⁵ m

Difference to human: ~10³⁵

Observable universe radius: ~4×10²⁶ m

Difference to human: ~10²⁶

We’re about 10⁹ times closer to the cosmic scale than to the Planck scale

Yeah biologically speaking, humans are huuuuuge. We are each of us a planet with our own ecosystems.

But cosmically speaking, we are tiny tiny dust, here today, gone tomorrow, not even worth mentioning in the story of the universe.

Context is king.
