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.
This week’s report from the Cosmos brings amazing stories ranging from What Existed Before the Big Bang to Forms of Consciousness We Can’t Recognize to World’s Scientists Share Their Expectations for the James Webb Space Telescope.
“The first galaxies in the early universe may illuminate what type of dark matter we have today,” says Mark Vogelsberger, associate professor of physics in MIT’s Kavli Institute for Astrophysics and Space Research about one of the great mysteries of modern physics. “Either we see this filament pattern, and fuzzy dark matter is plausible, or we don’t, and we can rule that model out. We now have a blueprint for how to do this.”
“Gravitational waves will bring us exquisitely accurate maps of black holes – maps of their space-time. Those maps will make it crystal clear whether or not what we’re dealing with are black holes as described by general relativity,” said Nobel Prize laureate, Caltech’s Kip Thorne. Now, scientists at Cardiff University’s Gravity Exploration Institute are using the technologies behind one of the biggest scientific breakthroughs of the century—the detection of gravitational waves led by Thorne— in the long-standing search for dark matter.
“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.
