“Cosmic ‘Funhouse’ Mirrors Reveal Unexplored Reaches of the Universe”

Gravitational Lensing

 

Cosmic “telescopes” –dark matter lenses– which warp light like funhouse mirrors in the form of the gravitational fields of dark matter clumps, may create “efficient lenses” that can magnify light from distant reaches of the universe revealing previously unknown objects and phenomena. Although dark matter is invisible because it does not emit light, that does not mean that it doesn’t interact with light at all and can be observed by space telescope such as the NASA/ESA Hubble observatory.

“Unexpected” –Hubble Reveals Something Missing in the Dark Universe

“One new theory says that dark matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity,” conjectured physicist Michio Kaku, about the mysterious, invisible phenomena that glues stars, dust, and gas together in a galaxy–its mass– and forms the foundation of our universe’s large-scale structure. Because dark matter does not emit, absorb, or reflect light, its presence is only known through its gravitational pull on visible matter in space. Astronomers and physicists are still trying to pin down what it is.

“A New Dark Force?”

"A New Dark Force?"

 

Everything we know about the universe and all the laws of physics, apply to four percent of the universe. The other 96 percent are the unknown phenomena of dark matter and dark energy. “If we account for all the matter and energy that we’re familiar with,” says Neil deGrasse Tyson, “and measure up how much gravity it should have, it’s one-sixth of the gravity that’s actually operating on the universe. We call that dark matter. It really should be called dark gravity. and we don’t know what that is.”

The German-Russian, eRosita space telescope mounted on the Spectrum-Roentgen-Gamma (SRG) was launched in July of 2019. Rotating at an observing position some 1.5 million kilometers from Earth, the spacecraft has created a seminal 3D map from 165 gigabytes of data, recording over a million violent sources of X-rays in the cosmos that reveals how the universe accelerates under the mysterious force called dark energy. The X-ray eye is expected to detect up to three million supermassive black holes, many of which will be new to science, including both obscured and unobscured objects, providing a unique view of the evolution of the supermassive objects within the emerging cosmos.

“Missing” — Could Dark Matter Be a Source of Light In the Universe?

"Chaos" --Our Spinning Cosmos May Be Losing Its Structure, Becoming More Disorderly

 

All the light in the observable universe provides about as much illumination as a 60-watt bulb seen from 2.5 miles away. And all the energy ever radiated by all the stars that ever existed is still with us, filling the universe with a sort of fog, a sea of photons known as the extragalactic background light. And yet, a discovery in 2014 suggested that the source of light in the universe from known populations of galaxies and quasars is not nearly enough to explain observations of intergalactic hydrogen. The filaments of hydrogen and helium that bridge the vast reaches of empty space between galaxies that astronomers use as a “light meter” yielded a stunning 400 percent discrepancy.
