Dark energy exchange

How does dark energy work?

Here’s how it works. What does dark energy do? Cause for concern? Dark energy is a hypothetical form of energy that is proposed by physicists to explain why the universe is not just expanding but is doing so at an accelerating rate.

Is dark energy tearing the universe apart?

Dark energy is tearing the Universe apart. What if the force is weakening? The first set of results from a pioneering cosmic-mapping project hints that the repulsive force known as dark energy has changed over 11 billion years, which would alter ideas about how the Universe has evolved and what its future will be.

Does dark energy exist?

The short answer is: We don’t know. But we do know that it exists, it’s making the universe expand at an accelerating rate, and approximately 68.3 to 70% of the universe is dark energy. Dark energy wasn’t discovered until the late 1990s.

How does dark energy affect the universe?

As it does so dark energy drives cosmic objects apart at an increasingly rapid rate rather than drawing them together as gravity does. Dark energy is estimated to account for between around 68% to 72% of the universe's total energy and matter  —  its matter/energy budget  —  meaning it heavily dominates both dark matter and everyday matter.

Could dark energy be a revolutionary discovery?

"The discovery of evolving dark energy would be as revolutionary as the discovery of the accelerated expansion of the universe itself, if confirmed with future data." What is the standard model of cosmology?

Why is dark energy called dark energy?

Their results indicated that the rate has accelerated over time, pushed by some unseen repulsive force that would later be dubbed dark energy. The name was intended to echo the equally mysterious entity known as dark matter — which is invisible but can be measured by its gravitational influence on galaxies.
