❤️ This pattern is customizable! You get three versions: one that says "mother", one that says "father", and one that says "ancestor". Some of us have mom issues, and that's ok. You can still make this pattern in a way that works for you. ❤️
Find this pattern in my Etsy shop. Link in bio.

My favorite tyrant joke: a man comes every day and peers at the front page of the newspaper without buying it.
The newspaper vendor says, "what are you looking for?"
"An obituary."
"Obituaries aren't on the front page."
"This one will be."

![Masses, sizes, and relative densities of objects in our Universe. Time-dependent background densities are color-coded as in Fig. 1. The diagonal white dashed isodensity lines correspond to the intersections in Fig. 1 of the vertical isochron lines with the black density line. Gravity and quantum uncertainty prevent objects of a given mass from being smaller than their corresponding Schwarzschild radius [Eq. (6)] or Compton wavelength [Eq. (7)]. Schwarzschild black holes lie on the black diagonal line which is the lower boundary of the “forbidden by gravity” region. The masses and Compton wavelengths of the top quark (t), Higgs boson (Ho), proton (p), electron (e), and neutrinos (ν) are plotted along the Compton () diagonal line. Among these, the top quark has the smallest Compton wavelength, because it has the largest mass: . The smallest possible object is a Planck-mass black hole indicated by the white dot labeled “instanton” (Ref. 20). Its mass and size are . The smallest observable (not yet evaporated) primordial black hole (PBH) that could have survived until today has approximately the same size as a proton (Ref. 21). The large low-mass black dot in the SMBH (super massive black hole) range is the 4 × 106 solar mass black hole at the center of our galaxy (Ref. 22), while the more massive large black dot is Ton 618. The dashed horizontal line at emphasizes the orthogonal symmetry of black holes () and particles ().
