Hickman (w) Yu (a)
In the middle of a classic Hickman high intensity sic-fi tale: Hyperion can sense that they have traveled only a short amount into the future due to the Sun's shift of 0.00003 in it's spectrum.
1.) Do Sun's have a spectrum? If so, of what?
2.) How does a spectrum shift?
1.) Yes, the Sun has a spectrum. As the sun undergoes nuclear fusion energy is emitted from the reaction, which gives us the bounty of light we have on Earth. Not all energy emitted from the fusion reaction is visible light it could fall anywhere within the electromagnetic spectrum. From gamma rays (most harmful) to radio waves (least harmful). visible light is in the middle of the two extremes.
2.) How can the Sun's spectrum shift? As the Sun continuously undergoes fusion, initially it starts fusing hydrogen atoms to make helium atoms. Then, the helium atoms will fuse with hydrogen to make lithium. This process goes on and on until fusing the atoms does no end in a net release in energy, which iron is the end element. So, shifting in spectrum means the ratio of elements fusing has shifted, decreasing the intensity of some light and increasing in others. This is how stars work and looking at their spectrum is akin to reading a hospital chart for a patient. You can get a run down of the history and see what their contents.
