Question

1. hubble’s law states: galaxies are moving away from us at a speed proportional to their distance from us. another way to state this would be that galaxies further away are moving faster than those close by. does the model that you created in class today support this? use data to support your answer.

Explanation:

Step1: Recall Hubble's law concept

Hubble's law is $v = H_0d$, where $v$ is recession - velocity, $H_0$ is Hubble constant, and $d$ is distance.

Step2: Analyze model data

Check the data from the class - created model for relationship between distance and velocity of galaxies. If the model shows that as the distance of a galaxy from us increases, its velocity also increases, then it supports Hubble's law. For example, if for galaxy A at distance $d_1$ has velocity $v_1$ and galaxy B at distance $d_2>d_1$ has velocity $v_2 > v_1$, it is in line with Hubble's law.

Answer:

If the data from the model shows that galaxies at greater distances from us have higher velocities of recession, then the model supports Hubble's law. If not, it does not support it.
