1. **What force is causing the Andromeda galaxy and the Milky Way galaxy to move towards each other?**
The primary force causing the Andromeda galaxy and the Milky Way galaxy to move towards each other is the gravitational force. Both galaxies have significant mass, and their mutual gravitational attraction is pulling them closer together, ultimately leading to a predicted collision in about 4.5 billion years.
2. **What is at the center of the Milky Way galaxy?**
At the center of the Milky Way galaxy lies a supermassive black hole known as Sagittarius A* (Sgr A*), which has a mass equivalent to approximately four million times that of our Sun.
3. **Our sun is considered a "medium size/energy" star. What color star is the sun of our galaxy?**
The Sun is classified as a G-type main-sequence star (G dwarf) and emits light that appears white from space, but it has a yellowish color as seen from Earth's surface due to atmospheric scattering. It is often described as a yellow star.
4. **Which wave on the electromagnetic spectrum is visible to the naked eye?**
The portion of the electromagnetic spectrum that is visible to the naked eye is known as visible light. This range of wavelengths spans approximately from 400 nanometers (violet) to about 700 nanometers (red).
5. **Which measurement of a wave determines the color?**
The color of light is determined by its wavelength. Different wavelengths correspond to different colors in the visible spectrum.
6. **What color of light is a blend of all frequencies?**
The color of light that is a blend of all frequencies in the visible spectrum appears white. When all the colors (wavelengths) of light are combined, they produce white light.
