If the dark matter particle has the properties predicted, that will open up essentially a whole new field of physics that will help us to ...The reason for the universe’s expansion is that the empty space creates even more empty space. This empty space has more energy than all that we know combined and it’s still ever-expanding. The study of dark energy and dark matter is pivotal in understanding our universe and our existence. Figure 3. An image of dark matter bending light due ...A wispy dark sector particle could interact with ordinary matter by emitting a dark photon that morphs into an ordinary photon. But that low-energy photon would barely nudge a nucleus. In the right semiconductor, however, the same photon could excite an electron and enable it to flow through the material.Nevertheless, astronomers still believe that somewhere between 30% and 99% of the Universe may consist of dark matter. Dark energy is the latest addition to the contents of the Universe. Originally, Albert Einstein introduced the idea of an all-pervading ‘cosmic energy’; before he knew that the Universe is expanding. Dark Energy and Dark Matter. All the atoms and light in the universe together make up less than five percent of the total contents of the cosmos. The rest is composed of dark matter and dark energy, which are invisible but dominate the structure and evolution of the universe. Dark matter makes up most of the mass of galaxies and galaxy clusters ... Around five billion years ago, the universe’s expansion started to speed up.
