All stable matter in the universe is made from lightest particles that signify these belong to the first generation; any heavier particles quickly decay to the next most stable level. When matter is made up to delineate forms that we can name and cherish say, a baby, remember it is made up at its fundamental level by particles and these are ‘condemned’ to decay. Growing from cradle to grave is not a curse but nature’s decree of changes.

Consider energy is neither created nor destroyed. So energy is passed around recycling which in human terms we may say we age and move from infancy to maturity leaving room for another generation of babies to take our place. There is a great democracy in this change: baby born with a silver spoon must make for a baby with a wooden spoon stuck into its mouth.

When we see the nature in its myriad colours we may understand that there are also quarks and leptons involved. Quarks come in three different colors which however when mixed create only colourless objects. For those who rely on their senses to make sense of the world, another world which has no colour, form or shape but equally admissible also exists. You may use your reason if you will or deny its existence. It matters little. Faith rules this realm given the hint that we can empirically know as existent at fundamental level.

The Standard Model

Everything in the universe is found to be made from a few basic building blocks called fundamental particles, governed by four fundamental forces. Our best understanding of how these particles and three of the forces are related to each other is encapsulated in the Standard Model of particle physics.

These particles occur in two basic types called quarks and leptons. Each group consists of six particles, which are related in pairs, or “generations”. The lightest and most stable particles make up the first generation, whereas the heavier and less stable particles belong to the second and third generations. All stable matter in the universe is made from particles that belong to the first generation; any heavier particles quickly decay to the next most stable level.

There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range. The electromagnetic force also has infinite range but it is many times stronger than gravity. The weak and strong forces are effective only over a very short range and dominate only at the level of subatomic particles. Despite its name, the weak force is much stronger than gravity but it is indeed the weakest of the other three.

The words of Jesus comes to mind, ‘The last shall be first. (Mt.19:30,Isa 33:23.) The lame shall take the prey. Weakness on a moral plane is humility. Principles of the Sermon on the Mount can be explained in its material make-up of matter.
