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...
Dark Matter and Dark Energy in the Universe 宇宙中的暗物质和暗能量 宇宙是一个神秘而广阔的存在,我们所知道的只是其中一小部分。在这个宇宙中,有两个神秘的力量,它们塑造了整个宇宙的演化和结构,它们就是暗物质和暗能量。 暗物质是一种我们无法直接观测到的物质形式,它不会发出或吸收光线,因此无法被传统的...
To model the observed Universe containing both dark energy and dark matter, we study the effective Yang-Mills condensate model of dark energy and add a non-relativistic matter component as the dark matter, which is generated out of the decaying dark energy at a constant rate Г, a parameter ...
Dark Energy Dark Matter in Science Lesson Summary Frequently Asked Questions What is a simple definition of dark energy? Dark energy is a supposedly unknown force which enables the expansion of the universe. Dark energy behaves, roughly speaking, as a phenomenon that opposes gravity. ...
Why does dark energy matter? There’s a lot riding on the answer. Because dark energy is the biggest component of the universe, its behavior determines the universe’s fate, explained David Spergel, an astrophysicist and president of the Simons Foundation. If ...
in their star formation rates, and in the amount of gas and dust they contain. And some are near, in cosmic terms, and some are billions of light-years away, at the edge of the universe. Many are found in groups, including our own Milky Way. Others are found within very large cluste...
dissertation was on the phenomenology of dark matter. Physicists estimate some 27 percent of the total universe is dark matter and the rest (68 percent) is a similarly shadowy phenomenon called dark energy. What makes dark matter so mysterious? “Everything you can see, everything you feel, ...
Physicist Patricia Burchat sheds light on two basic ingredients of our universe: dark matter and dark energy. Comprising 96% of the universe between them, they can't be directly measured, but their influence is immense. 文都...
For close on a century, researchers have hypothesized that the universe contains more matter than can be directly observed, known as "dark matter." They have also posited the existence of a "dark energy" that is more powerful than gravitational attraction discovered by Newton. ...
