Why is the sun a source of non-ionizing radiation? Where does the energy in fission come from? Where does dark energy come from? What is dark energy made up of? What is nuclear energy? What is the basic unit of energy? What is the source of a magnetic field?
The dominating form of energy in the cosmos dark energy is driving the accelerating expansion of the universe, but its nature remains a mystery.
mass and energy. The remaining 95% is thought to be made up of two other mysterious substances: “dark matter” and “dark energy,” both of which are invisible and peculiar in nature, yet both of which scientists also think play profound roles in the evolution and expansion of the ...

The rest of the universe is far from empty, however. Dark matter accounts for 23.3 percent of the cosmos, and dark energy fills in 72.1 percent [source: NASA]. Together, these materials make up a whopping 95.4 percent of the universe, so it's no wonder we're still trying to figure ou...
The nature of dark matter is still a mystery, but it is hypothesized to be made of undiscovered subatomic particles. Various experiments are underway to detect dark matter particles directly. Meanwhile, dark energy remains even more enigmatic, with its properties and origin being key questions in ...
Dark matter is entirely invisible, emitting no light or energy, making it undetectable by conventional sensors and detectors. Scientists believe that the key to its elusive nature lies in its composition. Visible matter, also called baryonic matter, consists of baryons — an overarching name for ...
Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought. The Dark Energy Spectroscopic Instrument uses a telescope to create a three-dimensional map of the universe over 11 billion years....
