SUMMARY
The discussion centers on calculating the recessional velocity of a galaxy located 500 Mpc away using Hubble's Law. Participants emphasize the need to express the velocity in kilometers per second, while also converting the age of the universe into seconds and years. The calculation requires a solid understanding of Hubble's Law, which relates the distance of a galaxy to its recessional velocity. Clear guidance on the setup and execution of these calculations is essential for accurate results.
