GIZMOS Student Exploration; Big Bang Theory | Hubble’s Law 2023. Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Standing by the side of a lonely highway at night, you see two motorcycle headlights, one in each direction. The headlight on your left appears brighter than the one on your right. 1. If the headlights are equally bright, which motorcycle is closer? The one on the left side Explain: If it is brighter than that means its going to be closer because the light particle...

GIZMOS Student Exploration: Big Bang Theory – Hubble’s Law 2023. Collect data: Locate and select the yellow Cepheid variable star (A-091) in the lower left section of the Andromeda Galaxy. Click the Collect data button. You will see a graph of the apparent brightness of the star over time. A. How does the star’s apparent brightness change over time? It decreases, then increases, and decreases again. Its like a pattern. B. Turn on Show time probes. Set the left probe at the first brigh...

ASTRON final exam Questions and answers, VERIFIED. Ch 17- What do we use medthods of stand candles? - -Astronomers cannot use parallax to measure vast distances because the angle by which the galaxy's position changes as we move around the sun is too tiny to be detected, so astronomers must use this method to find distance How do we use standard candles? - -if we know the luminosity we can use the inverse-square law to deduce its distance from how bright it looks to us Cepheids - -ar...
