Scientific Predictions and the Bible: What to Expect

Does the Bible make scientific predictions that have been shown to be accurate? Or do Christians simply find supposed scientific facts in the Bible after they have already been discovered by scientists? Should we expect the Bible to make predictions about future scientific discoveries if it is the inspired word of an all-knowing God? These are important and challenging questions that would be answered very differently by believing Christians or non-believing skeptics. Some Christians will claim that the Bible makes amazingly accurate predictions about what science will discover while skeptics may claim that those predictions were only recognized after they were already discovered by scientists, and that there are no future scientific predictions being proposed based on the biblical text.

Let's start this discussion with the question of what kind of scientific predictions we should expect to find in the Bible if it is the inspired word from an omniscient God. One thing I have learned about God over the years is that I am not able to predict what he should do or will do. I can only predict that God will always act in a way consistent with his character. In the Bible, the prophet Jonah also knew that God would always act consistent with his character, which is gracious and compassionate. Because Jonah didn't want God to act that way toward the people of Nineveh he initially refused to go to Nineveh to share God's message that they could avert judgement if they repented. When God did spare the city, Jonah was mad at God because God acted as he always does. Jonah said to God, "Isn't this what I said, Lord, when I was still at home? That is what I tried to forestall by fleeing to Tarshish. I knew that you are a gracious and compassionate God, slow to anger and abounding in love, a God who relents from sending calamity (emphasis added)." So when it comes to the question of what kind of scientific predictions we should expect to find in the Bible if it is the inspired word from an omniscient God, all I can say for certain is that anything revealed should be consistent with the known character of God.

A Look at the Top Quark

All the known matter in the universe is composed of two classes of particles: quarks and leptons. There are six types, or flavors, of quarks and six types of leptons. The figure to the left shows these fundamental particles. Three of the leptons, the electron (e), the muon (μ), and the tau lepton (τ) have an electrical charge that is a factor of –1 that of a proton, and three of the leptons, called the electron neutrino (νe), the muon neutrino (νμ), and the tau neutrino (ντ) have zero electrical charge. Quarks are named (in order of increasing mass) up (u), down (d), strange (s), charm (c), bottom (b), and top (t). The up, charm, and top quark have a charge that is +2/3 that of a proton, and the down, strange, and bottom quarks have a charge that is –1/3 that of a proton.

Therefore, in an atom composed of a nucleus surrounded by electrons, the electrons are fundamental particles, which means they are not composed of anything smaller as far as we know. But the nucleus is composed of neutrons and protons, which are themselves composed of quarks. At a very basic level a proton is made up two up quarks and a down quark with electric charge +2/3 + 2/3 – 1/3 = 1 while a neutron is made up of one up quark and two down quarks with an electric charge of +2/3 – 1/3 – 1/3 = 0. The two quarks and two leptons in the first column in the figure are called the first generation of particles, the second column is the second generation of particles, and the third column is the third generation of particles. Most of all the matter we know of is made of the first generation of particles since atoms are made of neutrons and protons and electrons with the neutrons and protons made of up and down quarks.

A New Particle Discovered at CERN

About a week ago, an experiment at CERN announced the discovery of a new particle, the Ξcc++ (pronounced Ksigh-see-see-plus-plus). Many people who have read about this discovery have asked me about its significance and if I was involved. So, this post will deviate from the usual discussion of the relationship between Christianity and science and focus on the discovery of the Ξcc++ with a few additional observations in my conclusion.
