The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope found that high-energy photons of gamma radiation from a distant galaxy arrived at Earth four minutes after lower-energy photons, although they were apparently emitted at the same time. If correct, that would contradict Einstein's theory of relativity, which says that all photons (particles of light) must move at the speed of light.
What does represent Direct Physical evidence of the dynamics of the universe? 1. The average separation of Hydrogen Clouds? 2. The average separation of galaxies? 3. The average temperature. Is it increasing, decreasing or staying the same?
It goes dark at night- no great revelation there.Do you understand that this means one of three things.There's something odd about our bit of the universeThe universe hasn't been around forever orThe universe is finite in its extent?
