What constitutes time?

A definition of time can be found within the second law of thermodynamics, in entropy. From entropy we can establish a direction for the flow of time within the classical physics world. Entropy at its core is about energy and heat transfer. Heat can be transferred from one body to another by electromagnetic radiation.

Electromagnetic radiation has several measurable components, wavelength, electron volt and frequency and its energy can be calculated using classical and quantum methods, seen as a wave or a particle. Waves and oscillations permeate the universe and are present in whatever form of tool we use to describe the world about us.

One component of a wave or an oscillation is its frequency. We can experience frequency in the form of an earth tremor, as the ground shakes and the earth’s mantle vibrates. The word frequency is defined as being, “The rate of repetition of a regular event. The number of cycles of a wave, or some other oscillation or vibration”, source: Oxford Dictionary of Science, John Daintith, Elizabeth Martin, et al., 2005, Oxford University Press.

Subatomic particles can be broken down into smaller and smaller components. LHC at CERN is attempting to confirm experimentally what theoretical physicists postulate for the structure of matter. I am proposing a thought experiment as to postulate further what time is. Continue reading
