We have a bit of a crisis on our hands — a dark matter crisis if you will. That’s because, for years, scientists theorized that dark matter, an unseen force, helps hold the universe together. However, new research suggests that our current models of the universe are wrong about how old the universe is and …
But there may be opportunities to indirectly spot the signatures of those gravitons. One strategy Vafa and his collaborators are pursuing draws on large-scale cosmological surveys that chart the distribution of galaxies and matter. In those distributions, there might be âsmall differences in clustering behavior,â Obied said, that would signal the presence of dark gravitons. …
Astronomers have made an astounding discovery. According to a new paper featured in Nature Astronomy, we have now detected dark matter in the cosmic web for the very first time. The cosmic web is a proposed web of filaments that scientists believe stretches throughout the universe, catching galaxies in it like a spider might catch …
Space is a really big place. In fact, our universe is more massive and expansive than we can probably ever fully understand. To give us a taste of just how big everything is, the scientists using the eROSITA X-ray telescope have created the largest X-ray map of the universe ever. The map, which is part …
A new study could challenge our current understanding of the universe’s age. According to a new study published in Nature Astronomy, the universe may not actually be 13.8 billion years old, as researchers previously estimated. The current estimate of the universe’s age is based on what we call the Standard Model of cosmology. This model …
Understanding the universe is a gamble and one that we could have been approaching incorrectly for almost a century. Now, a new theory that suggests our galaxy could be surrounded by a void could help better explain the acceleration, and some are calling it a “Hubble Bubble.” For years, scientists have explained the acceleration of …
Like any object, black holes take time to grow and form. And like a 6-foot-tall toddler, Fan’s supersize black holes were too big for their age—the universe wasn’t old enough for them to have accrued billions of suns of heft. To explain those overgrown toddlers, physicists were forced to consider two distasteful options. Decades ago, …
