Understanding the Mystery of Matter in the Universe – Why Is There Any Matter in the Universe at All?

by University of Sussex, SciTechDaily

Scientists one step closer to understanding the mystery of matter in the universe.

Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe — more precisely than ever before. Their research is part of an investigation into why there is matter left over in the universe, that is, why all the antimatter created in the Big Bang didn’t just cancel out the matter.

The most massive explosion since the Big Bang was just spotted in deep space

by Mike Wehner, BGR

As far as astronomers know, the Big Bang is why we’re all here. The massive explosion sent all the matter we see in the universe flying, expanding rapidly and coalescing into the stars, planets, and other objects that fill the cosmos. Now, astronomers have detected what they believe is the largest explosion ever observed by humans, and it took place in a cluster of galaxies nearly 400 million light-years away.

The record-breaking explosion is believed to have originated in a black hole at the heart of the Ophiuchus galaxy cluster. It was spotted using data from NASA’s Chandra X-ray Observatory as well as the ESA’s XMM-Newton and other instruments in Australia and India.

Astronomers Are Closing in on The Precise Moment The Universe Lit Up

by Evan Gough, ScienceAlert

A team of scientists working with the Murchison Widefield Array (WMA) radio telescope are trying to find the signal from the Universe’s first stars. Those first stars formed after the Universe’s Dark Ages.

To find their first light, the researchers are looking for the signal from neutral hydrogen, the gas that dominated the Universe after the Dark Ages.

A Mirror Image of Our Universe May Have Existed Before the Big Bang

by Erik Vance, LiveScience

Like a mountain looming over a calm lake, it seems the universe may once have had a perfect mirror image. That’s the conclusion a team of Canadian scientists reached after extrapolating the laws of the universe both before and after the Big Bang.
