How Do We Know Dark Energy Exists?
• University TodayI've talked about how astronomers know that dark matter exists. Even though they can't see it, they detect it through the effect its gravity has on light. Dark matter accounts for 27% of the Universe, dark energy accounts for 68% of the Universe. And again, astronomers really have no idea what what it is, only that they're pretty sure it does exist. 95% of the nature of the Universe is a complete and total mystery. We just have no idea what this stuff is.
So this time around, lets focus on dark energy. Back in the late 90s, astronomers wanted to calculate once and for all if the Universe was open or closed. In other words, they wanted to calculate the rate of expansion of the Universe now and then compare this rate to its expansion in the past. In order to answer this question, they searched the skies for a special type of supernova known as a Type 1a.

We DON'T know that dark energy or dark matter exist. We don't even know that there was a Big Bang, or that stars operate through atomic fusion. It is all theory.
Scientists and astronomers are constantly finding out new things about the universe, things that are constantly making them adjust their previous findings, add new theories and ideas, try to fit things together than don't really fit, and keep themselves from looking like a bunch of idiots at the same time. Well, there is a new (not really) thinking starting to take hold. It is called the electric cosmos.
The electric cosmos idea states that the stars are gigantic electric plasmas, not nuclear at all. It suggests that there are three forms of electric plasma that permeate the universe, the stars being one form. Based on the way electric plasmas work, virtually all the questions about the operations of stars and the the universe are answered. It does away with the theory of the Big Bang, with the idea of black holes, with the billions of years-old universe, and with the idea that the universe is billions of light years big.
The Guy that made the electric cosmos idea famous was an astronomer named Ralph Juergens. In 1949 Ralph Juergens showed that the actions of the whole cosmos easily fit the actions of electric arcs and electric plasmas. One of the things that Mr. Juergens recognized is that, "There is now enough inescapable evidence that a majority of the phenomena we observe on the Sun are fundamentally electrical in nature." (quote by Donald E. Scott, Ph.D.)
