, floating within and through spacetime. - Quote by Christophe Galfard)
Save
The air around you is filled with floating atoms, sliding down the Earth’s spacetime curve. Atoms first assembled in the cores of long-dead stars. Atoms within you, everywhere, disintegrating in radioactive decays. Beneath your feet, the floor – whose electrons refuse to let yours pass, thus making you able to stand and walk and run. Earth, your planet, a lump of matter made out of the three quantum fields known to mankind, held together by gravity, the so-called fourth force (even though it isn’t a force), floating within and through spacetime.
