What is dark energy? A. Matter that does not interact with light. B. Matter that can be detected by its gravitational effects on visible matter. C. A mysterious force that is causing the expansion of the universe to accelerate. D. Regions of space where the gravitational pull is so ...
The article discusses the mystery of dark energy, a hypothetical force that accelerates the expansion of the universe, and its impact on cosmology and astrophysics. Three explanations for dark energy are presented, including the theory of a "cosmological constant" derived from scientist Albert ...
The dominating form of energy in the cosmos dark energy is driving the accelerating expansion of the universe, but its nature remains a mystery.
The dominating form of energy in the cosmos dark energy is driving the accelerating expansion of the universe, but its nature remains a mystery.
Dark matter is a theoretical substance that exerts gravitational forces, affecting the universe's structure, while dark energy accelerates the universe's expansion.
Dark energy and dark matter account for most of the universe, but what are these elusive phenomena? NASA/JPL/Hubble NASA's Wilkinson Microwave Anisotropy Probe (WMAP) provided a true watershed moment in humanity's quest to understand the cosmos when it calculated the age of the universe and...

matter--much like dark matter--and it is referred to as energy because one of the few things we are certain of is that it contributes nearly 70 percent of the total energy of the universe. If we can figure out what it really is, it is certain we will find a more illuminating name....
Another way to explain Dark Energy is suggested by String Theory. All matter and energy, including photons (light), have vibrating strings as their basis. String and anti-string pairs are speculated to be created in the quantum foam, a roiling energy field suggested by quantum mechanics, and...
matter might be concentrated inblack holes, the powerful gates to nothing that due to the extreme force of their gravity devour everything in their vicinity. As such, dark matter would have been created in theBig Bangtogether with all other constituting elements of the universe as we see it ...
