The goal of the ether theories was to describe that medium. For light to exist, ether theory suggests that a medium must exist. Over the next century, several solutions that attempting to explain the propagation of light or the movement of gravity were all proposed as various ether theories. If that was the case on our planet, then what could the aether be like when considering celestial bodies or the vastness of the universe? He wrote that although spaces may have seemed empty, they could be filled with compact and dense bodies that could not be distinguished through mere perception. It was Isaac Newton who suggested the idea that an aether could exist in 1718. The reasoning behind Einstein’s thinking is known really only to him, but may be based on the ideas of luminiferous aether and mechanical gravitational aether. “The idea of motion may not be applied to it.” This means the aether could potentially stand alone, outside of the rules of relativity that Einstein proposed. “This aether,” Einstein wrote, “may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time.” When Albert Einstein proposed the theory of general relativity, he referred to the gravitational field within the theory as “aether.” His terminology never gained real support, but the concept still remains. Although modern physics does look at non-standard interpretations, the presence of the ether theory still holds relevance. There are several different ether theories that have been proposed over the years, but most have fallen out of favor by modern physicists because of the development of rules regarding special relativity. “Aether” is the Greek word for air, a reference to either heavenly or fresh air, and it is believed that this medium must be a space-filling substance for the transmission to occur. If you are running both the Aether server and web browser client on the same computer, modify the line that starts with 127.0.0.Ether theory, or aether theories, is an idea in physics which proposes the existence of a medium that can transmit gravitational or electromagnetic forces. Using your favorite plain text editor, open /etc/hosts for editing. You will need to edit your /etc/hosts file which will require Administrator or root permissions. It only needs to be done on the machine that you will be using your web browser from. In this environment, we need to define some domain names that will resolve to the actual location of the server. Local Browser ClientĪs mentioned earlier, we are actually setting up an Aether development environment for these exercises.

In production, Aether is deployed and maintained using Kubernetes, a more robust system that takes advantage of this technology.īefore following this run-through, make sure you have met the prerequisites defined in the previous section. The container we use is Docker and we use Docker Compose to define and script deployment configurations (this is known as “orchestration”). More specifically, it utilizes container-based virtualization, which allows multiple isolated systems, called containers, to run on a single host and access a single kernel. Aether actually consists of several different servers and services that run in their own virtual network environment.
