Hey ! So we found some of that dark matter, :rofl: woohoo ! But honnestly, I thought their had been a misprint on the Chandra site when I read that they calculate the temperature of these webs of particles to be 1 000 000 °C ! ? ! ? ! ? ! How the #!*@¤ did we not see something that's so blazing hot before ? The SCIAM article talked about it being to hot to see ? Can someone explain that ? I gather this is a humongous reservoir of energy. Did we expect anything like this ?
