Physics reveals you occupy no absolute position in the universe

Kurzgesagt – In a Nutshell////2 min read

The illusion of cosmic stillness

Human intuition suggests we sit atop a stable, fixed stage. We mark our maps with north and south, anchoring our identity to specific coordinates on a solid sphere. However, theoretical physics strips away this comfort. Absolute Position is a phantom concept; without objects to serve as landmarks, empty space is entirely uniform. You only exist at a "position" in relation to something else. We are not standing still; we are caught in a complex, multi-layered dance of celestial mechanics.

Earth's violent, jiggling orbit

Our home is far from a serene marble. While we imagine Earth tracing a perfect circle, the reality is a messy, elliptical jiggle. As we orbit the Sun, the Moon exerts a massive gravitational tug, dragging our planet's center of gravity 4,700 kilometers off-center. Every 100,000 years, the very shape of our orbit shifts, ensuring that the ground beneath us is never truly in the same place twice.

Corkscrewing through the Milky Way

The Solar System does not sit flat within our galaxy. We are tilted 60 degrees relative to the galactic plane, hurtling through the Milky Way at nearly a million kilometers per hour. From a distant perspective, our movement resembles a giant corkscrew or helix. We dive through the dense galactic disk like a dolphin, shooting up and down hundreds of lightyears in cycles that last tens of millions of years.

Reaching the end of greatness

As we zoom out further toward the Laniakea Supercluster, even these massive motions begin to blur. At the largest scales, the universe reaches what astronomers call the "End of Greatness." Here, the cosmic web becomes homogeneous. Everything looks the same in every direction. In this vast uniformity, the idea of a "center" or a "correct" orientation vanishes entirely, leaving us with a profound sense of cosmic humility.
