Compare the sizes between a proton, neutron, and electron

• Protons and Neutrons each equal 1 amu/ electron essentially has no mass

• Protons and neutrons don't have mass, and electrons have 1 amu

• protons and electrons have no mass, neutrons contain the mass of an atom

• Protons, neutrons, and electrons carry the same mass- 1 amu each

Ionizing Radiation is...

• BAD for you

• Safe for you

• Radio waves, Microwaves, infrared, and visible light

• seen to us in colors when it goes through a prism

As galaxies move away

• they slow down

• they continue to accelerate and expand

• their spectrum shifts towards the blue/violet

• they cool down
