WebThe Hubble time is the right age for the universe only if the expansion rate has been constant throughout the time since the expansion of the universe began. Continuing with our end-of-the-semester-party analogy, this is equivalent to assuming that you traveled home from the party at a constant rate, when in fact this may not have been the case. WebHubble’s Law Below is a table of galaxies, their distances, and their velocities. The table is not yet complete. You will collect the missing data and graph Hubble’s law to measure the age of the universe.

WebHubble's Law, when written in this form, $$ v = H_0D, $$ means: if $D$ is the current distance of a galaxy, and $H_0$ the Hubble constant, then $v$ is the current recession velocity of the galaxy. So it tells you what the recession velocity of a galaxy is right now, not what it was in the past. WebThe yellow square marks the present in all four cases, and for all four, the Hubble constant is equal to the same value at the present time. Time is measured in the vertical direction. The first two universes on the left are ones in which the rate of expansion slows over time. irene willis chicago il

WebMar 2, 2024 · Hubble's Law Quiz Here are some fundamental questions regarding the expansion of the universe as described by Edwin Hubble. 1. What is the relationship between a galaxy's distance and its motion relative to us? 2. How old is the Universe? 3. Why does galaxy recession mean the universe is expanding? 4. What is meant by the cosmic … WebFeb 23, 2024 · While Hubble is unable to see the very first galaxies, it can track the development of galaxies over much of cosmic time. Expand Image A selection of spiral galaxies from the Great Observatories Origins Deep Survey (GOODS) are grouped by their distance, and therefore by the time at which they are seen. WebTo be able to compute a meaningful distance from the Hubble law, we must deal with galaxies for which the expansion velocity is much greater than these random velocities: at least 5000 km/s. What is the distance corre- sponding to this speed of 5000 km/s? The Hubble Law tells us that v = H0d. ordering essays online
