# What is Dark Energy?

## Background

Around 14 billion years ago… the universe is believed to have originated from a single point, with a “Big Bang”. Although it was expected that galaxies would be moving away from each other, in the late 1990s… it was found that the expansion of galaxies is strangely accelerating (going faster).

To accelerate, an energy would need to exist to cause the force on galaxies.  Since it is an unknown source, scientists call it dark energy.

73% !!!

Today, it is believed that 73% of all energy in the universe is dark energy. By comparison, ordinary matter makes up only 4% of the universe’s energy. Most of the energy in the universe is an unknown “dark” source.

## Explanation

### Aether

In the EWT equations for energy and forces, a density property exists, implying a medium in the universe for waves to travel. This medium, or “substance”, is often referred to as the aether. It exists throughout the universe, including between galaxies which need energy to continue to accelerate.

By definition, the aether is the substance that allows energy to travel in waves. Thus it is a likely candidate for being dark energy if the aether can be proven one day.

If the flow of of waves through the aether is indeed the missing dark energy, it still needs to account for observations that galaxies continue to accelerate. Why would this be the case, 14 billion years after the Big Bang?

### Accelerating Galaxies

In EWT, all forces are derived from a single law where wave centers move to minimize wave amplitude. For example, a particle moving to minimize traveling, longitudinal wave amplitude is the electric force. An example is provide below where a particle experiences higher wave amplitude on one side (left side) and the result is motion of the particle in the direction of lower wave amplitude/energy. It will accelerate until wave amplitude is equal. A real world example of this is a beach ball in a pool with higher waves pushing on it from one end compared to the other end – it will travel in the direction with lower wave amplitude.

The same concept applies to galaxies in the universe. After all, galaxies are made from the same particles. According to the laws of EWT, energy travels as waves through the universe and are reflected from wave centers. Waves are constructive, such that amplitude is higher as more waves converge as they travel. Thus a concentration of mass on one side of a galaxy will produce more waves, which by the time they reach the galaxy, converge into a wavefront (according to Huygen’s principle) with a higher wave amplitude when compared to the waves reaching the galaxy from the opposite end. This is illustrated below. The galaxy is circled in red. To its left is a wave with higher amplitude (compared to its right) in the direction of the center of the universe due to a higher concentration of mass that is continually reflecting waves. As a result, the galaxy accelerates away from the center of the universe.

The vast majority of the waves are expected to be traveling, longitudinal waves that decrease with the square of the distance, so at some point it would be expected that the wave amplitude would be equal and the galaxies should stop accelerating.
