Dark Energy, What it could be? | Skeptic Society Magazine
One of the shocking revelations of the late 20th Century was that the universe was expanding at an accelerating rate. Before that mysterious “speed-up” was discovered, people thought that the rate must be slowing down as the universe expanded. What’s worse, at the time of discovery, there was no known mechanism to explain how the expansion of the universe could be accelerating. Guess what! There still isn’t a well-explained one. But, at least whatever it is has a name. This mysterious driving force is known as Dark Energy. There are a few possibilities of what it could be. IS DARK ENERGY A PROPERTY OF SPACE-TIME? General relativity is often thought of as a theory of gravity, mostly because this is its greatest application as it explains the dynamics of objects in accelerating reference frames (like a gravitational field). However, general relativity is more than that, and it has far reaching implications into the vary nature of the universe. One of the most amazing consequences of Einstein’s theory is that empty space isn’t really empty. In fact, empty …
