Somewhere, somewhere in the universe, there is a lot of matter that we have not yet been able to find. And it’s not a trivial amount, either. About 70 to 80 percent of all mass is thought to be the mysterious stuff known as dark matter. Normal matter is the minority. That’s all we can … Read more
Recent studies have dealt a major blow to the hypothesis that primordial black holes could be responsible for dark matter, shifting the focus of scientific research to alternative explanations. Overview of the research Two pivotal studies have explored the possibility of this original black holeswhich is believed to have formed in the early universe, could … Read more
Artist’s impression of a microlensing event caused by a black hole observed from Earth towards the Large Magellanic Cloud. The light from a background star in the GMC is diffracted by a putative primordial black hole (lens) in the Milky Way’s halo and magnified when observed from Earth. Microlensing produces very characteristic variations in the … Read more
In our rapidly expanding universe, the lives of stars follow well-worn tracks, fusing hydrogen and then helium before growing in size until they exhaust their nuclear fuels and collapse, no longer able to resist gravity. But some stars in the innermost part of our Milky Way, very close to the galactic center, could chart their … Read more

Using gravitational lensing, scientists have discovered that dark matter can extend more than a million light-years from galactic centers, proposing significant adjustments to our theories of gravity or the concept of dark matter itself. Credit: SciTechDaily.com Groundbreaking new research shows that the rotation curves of galaxies remain flat far away, confirming the predictions of modified … Read more

The main technique Mistele used in his research, gravitational lensing, is a phenomenon predicted by Einstein’s general theory of relativity. As part of the research, Mistele plotted the so-called Tully-Fisher relationship on a map to highlight the empirical relationship between … Read more
