About Attometers
An attometer (am) is one quintillionth of a meter (10⁻¹⁸ m), smaller than atomic nuclei but larger than the realm of pure theory. This scale represents the size of individual quarks within protons and neutrons, though quarks are considered point particles with no measurable size. Attometers are used in high-energy physics experiments that probe the internal structure of protons through deep inelastic scattering, revealing the distribution of quarks and gluons within.
About Megaparsecs
A megaparsec (Mpc) is one million parsecs or 3.26 million light years, the standard unit for measuring intergalactic distances. The Andromeda Galaxy is about 0.77 megaparsecs away, while most galaxies in the observable universe are measured in megaparsecs. The Local Group of galaxies spans about 3 megaparsecs. Astronomers use megaparsecs in combination with redshift measurements to calculate distances to distant galaxies and study the expansion of the universe. The Hubble constant, describing cosmic expansion, is expressed in kilometers per second per megaparsec.
