The fine-tuning of the universe for the existence of life is fascinating to me. That’s why I was so excited to find A Fortunate Universe: Life in a Finely Tuned Cosmos, co-authored by astrophysicists Geraint Lewis and Luke Barnes,...These three particles are responsible for building the 92 naturally occurring elements, as well as the unstable elements that have been created in the laboratory. [...]
atoms are made up of subatomic particles: neutrons, protons, and electrons. Protons, which are positively charged, and neutrons, which have no charge, compose the nucleus of the atom. Negatively charged electrons orbit the nucleus[...]
scientists have discovered that protons and neutrons are made of quarks. Specifically, they are made of a combination of up quarks and down quarks.[...]
These three particles—the up quark, the down quark, and the electron—make up everything we see—molecules, mice, maple trees, and the Milky Way galaxy. And each of these particles has a distinct mass. The mass of an electron is approximately 9.1 x 10-31 kg. [...]
they are finely tuned for the existence of life. Consider how the universe would be different if the masses of the up quark and down quark were slightly different. Barnes and Lewis write, “In fact, it is rather easy to arrange for a universe to have no chemistry at all. Grab a hold of the particle mass dials and let’s create a few universes.”1
So what happens if we change the masses of the three fundamental particles—the down quark, the up quark, and the electron? Let’s see.[...]
the masses of the up quark, down quark, and electron are extremely fine-tuned for the existence of life. Not merely the existence of human life, any kind of life. These masses could have taken any number of values.4 Yet, they fell within the extremely narrow range of values that permits the existence of life.
The Universe Really Is Fine-Tuned, And Our Existence Is The Proof [300 word excerpts of an over 2,600Ph article] 1/6/2025, 4:46:08 PM · by daniel1212 · 61 replies Forbes.com ^ | Dec 19, 2019, | Ethan Siegel https://freerepublic.com/focus/f-chat/4288389/posts
Search function works fine.
I posted those myself, and so I am mystified as to the meaning of "Search function works fine"
= "We Couldn't Live in a Universe in Which Life Can't Exist"
A virtual tautology!
