Document Summary

Light moves as a particle and then interacts as a wave. Doppler: usually used for weather, the rays of lights off of stars are tangent, doppler sound is a shift in frequency. In a car sound is that at the beginning is the high pitch and at the end is the low pitch. When the car is not moving it creates compression waves. Because the car is moving slightly closer to you, what you hear is the compressed sounds that shows a high pitch. When the car is going away you will hear the expanded sound that shows the lower pitch. The whole universe is in a red shift: expansion. Dark force and dark matter is not quantified and can"t be measures. Has nothing to do with gravity, free of apart, locally, weak: unified force field. Gravity, electromagnetic force, nuclear force, and decay weak force. Einstein tried to join the forces together, but it was difficult.
