SUMMARY

The discussion clarifies that not everything outside the local group is moving away from us. Specifically, M86 is confirmed to be moving towards us, and there is uncertainty regarding M81's motion. This highlights the complexity of cosmic movements within the Virgo Supercluster, where some galaxies may exhibit different trajectories. Understanding these dynamics is essential for accurate interpretations of cosmic expansion.

PREREQUISITES
  • Basic understanding of cosmic structures, such as the local group and Virgo Supercluster.
  • Familiarity with galaxy motion and redshift concepts.
  • Knowledge of astronomical observation techniques.
  • Understanding of gravitational interactions between galaxies.
NEXT STEPS
  • Research the motion of galaxies within the Virgo Supercluster.
  • Study the concept of redshift and its implications for cosmic expansion.
  • Explore gravitational interactions and their effects on galaxy trajectories.
  • Learn about observational techniques used in measuring galaxy distances and velocities.
USEFUL FOR

Astronomy enthusiasts, astrophysicists, and students studying cosmic structures and galaxy dynamics will benefit from this discussion.

This is a simple question but i keep finding conflicting answers and don't understand scientific and mathamatical language well enough to consult reliable data.. 'Cause I'm a dunce.

So, is EVERYTHING outside the local group leaving us, or are some things in the virgo supercluster contracting? For example, is M81 coming or going?

No. M86 is not. I believe M81 is not as well, but I am certain about M86.
