A team of researchers using the Chandra X-Ray Observatory have spotted a wave of hot gas larger than the Milky Way in the Perseus galaxy cluster.
The post A Single Wave, Bigger Than the Milky Way, is Rolling Through the Perseus Galaxy Cluster appeared first on Universe Today.
Light is tricky stuff, and it took scientists hundreds of years to puzzle out what this stuff is. But they poked and prodded at it with many clever experiments to try to measure its speed, motion and interaction with the rest of the Universe. For example, the Fizeau Experiment, which ran light through moving water […]
Waves move through a medium, like water or air. So it seemed logical to search for a medium that light waves move through. The Michelson-Morley Experiment attempted to search for this medium, known as the “luminiferous aether”. The experiment gave a negative result, and helped set the stage for the theory of General Relativity. (…)Read […]
