Astronomers using observations from NASA’s Hubble Space Telescope and +NASA's Chandra X-ray Observatory have found that dark matter interacts with itself even less than previously thought by researchers. This finding narrows down the options for what this mysterious substance might be.
By finding that dark matter interacts with itself even less than previously thought, the team has successfully narrowed down the properties of dark matter. Particle physics theorists have to keep looking, but they now have a smaller set of unknowns to work with when building their models.
Please join +Tony Darnell Dr.+Carol Christian and +Scott Lewis as they discuss these amazing observations with the team that made them along with special guest Dr.+Katie Mack
