Our Universe provided some fascinating news stories over the past few days, ranging from Antimatter Stars of the Milky Way to Can Early Dark Energy Save the Universe to Our Weird Solar System.
The beauty of the Universe is that there’s always a mystery. Scientists might have an explanation for the existence of an especially cold region in the afterglow, known as the CMB Cold Spot. Its origin has been a mystery so far but might be attributed to the largest absence of galaxies ever discovered.
Are LIGO gravitational wave observations of merging black holes an illusion? In 1966, Erast Gliner, a young physicist at the Ioffe Physico-Technical Institute in Leningrad, proposed a hypothesis that very large stars should collapse into what could now be called Generic Objects of Dark Energy (GEODEs). GEODEs appear to be black holes when viewed from the outside, but unlike black holes, they contain dark energy instead of a singularity.
“If we combine the map of the dark matter in the Milky Way with the most recent Big Bang model to explain the universe and we hypothesize the existence of space-time tunnels, what we get is that our galaxy could really contain one of these tunnels, and that the tunnel could even be the size of the galaxy itself. But there’s more,” explained Paolo Salucci, astrophysicist with SISSA and a dark matter expert. “We could even travel through this tunnel, since, based on our calculations, it could be navigable.” Salucci is among the authors of the paper published in Annals of Physics.
The Universe has showered us with amazing, thought-provoking headlines this week, from why alien hunters have spent 60 years finding new solutions for the Drake Equation to the biggest “Oh No” moment in the Solar System to humanity’s unlikely gateway to space.
Another amazing week of news from the Cosmos: from Einstein’s forgotten idea that might save cosmology to the physicist who denies that dark matter exists to black holes may be expanding along with our Universe. This week’s Galaxy Report brings you news of space and science that has the capacity to provide clues to the mystery of our existence and adds a much needed cosmic perspective in our current Anthropocene Epoch.
