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

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
