dark energy

From The Conversation: Bizarre ‘dark fluid’ with negative mass could dominate the universe – what my research suggests Article: A unifying theory of dark energy and dark matter: Negative masses and matter creation within a modified ΛCDM framework A new extended version of LambdaCDM unifies...

Sometimes I ponder things, and some of those ponderations lead me to suspect that I'm misunderstanding some of the fundamentals. For the sake of discussion, let's take it as a given that the universe is expanding, and that the rate of expansion is increasing, and that eventually this will...

"Using Maupertuis’ form of the principle of least action, Arto Annila has calculated that the brightness of light from Type 1a supernovae after traveling many millions of light-years to Earth agrees well with observations of the known amount of energy in the universe, and doesn’t require dark...

Picture where ( though there is no actual beginning) space itself is tightly wound in to a coil. It begins to unfurll once it has reached a point where it can no longer coil. This is space that is begining to appear and uncurl in an opposing direction to the initial coiling. , Imagine you take a...

I've received a CV for a web-related job from a guy with a PhD in Theoretical Physics, and in amongst his work history is a reference to a paper he's written regarding his theory of a possible explanation for dark energy. I know of some of the terms he talks about, but I couldn't judge if it's...

We know that space between galaxies expand. But inside galaxies or solar systems it does not seems to happen. To understand the apparent acceleration of the universe one must first ask: Why does space inside galaxies or solar system not seems to expand. This makes no sense. For example...

Warning: This is wild speculation from someone who probably doesn't know what he's talking about. Please link me to any resources that would set me straight. :) Cliffs Notes: Could the possibility of a fundamental resolution to the universe explain dark matter/energy? Something about the...

As a freelance science writer, I'm always on the look-out for some interesting ideas I can write about or sell, or do interviews on. I haven't done magazine articles for a while and figured once I've finished my current radio project I'd stitch together something on an idea I had recently. I'm...

Scientific American's cover article this month posits an idea that may bypass the perplexing notion of dark energy: http://www.sciam.com/article.cfm?id=does-dark-energy-exist Dark energy being hypothesized as an explanation for the acceleration of the universe's expansion, as a result of the...

http://www.washingtonpost.com/wp-dyn/content/article/2006/08/21/AR2006082101139.html Everything we know, everything we can detect, is only 5% of the entire Universe! - Extraordinary claim! 20% of the Universe is something we can't see or detect, that doesn't obey the laws of physics, except it...

I have a very small understanding about dark energy, but am still trying to grasp how it works. Like many people, I find that a good analogy helps. My understanding of dark energy is that it permeates space fairly evenly, and causes a negative pressure on spacetime. This negative pressure...

Despite the force of gravity, the universe is apparently expanding. Scientists have speculated on the existence of 'dark energy' to explain the force that overcomes gravity. What are the chances of us detecting this energy directly, if any? And if we can detect it, and later can generate it...

From what I've read, I understand that the space between objects in the universe is expanding in a way unrelated to actual velocity of said objects, and the energy to do so is how a portion of "dark matter" is to be reconciled with other things in cosmology. So my question is, that being so...
