SUMMARY

The discussion clarifies the relationship between Hubble's Constant, which is 70 km/s/Mpc, and its implications for cosmic inflation and the Hubble horizon. Hubble's Constant defines the rate of expansion of the universe, influencing how far we can observe due to the finite speed of light. Understanding this relationship is crucial for grasping how the universe's expansion affects the observable horizon during inflationary periods.

PREREQUISITES
  • Understanding of Hubble's Constant and its value (70 km/s/Mpc).
  • Basic knowledge of cosmic inflation concepts.
  • Familiarity with the concept of the observable universe and Hubble horizon.
  • Awareness of the speed of light and its role in cosmology.
NEXT STEPS
  • Research the implications of Hubble's Constant on cosmic expansion.
  • Study the concept of cosmic inflation and its historical context.
  • Explore the mathematical relationship between Hubble's Constant and the Hubble horizon.
  • Investigate the effects of the speed of light on observable universe limits.
USEFUL FOR

Astronomy students, cosmologists, and anyone interested in understanding the dynamics of the universe's expansion and its observable limits.

Ok I'm kinda confused of what is the relationship between hubble's constant, hubble's horizon length and how all those calculation works. I'm reading a textbook called quarks, leptons and the big bang but they don't explain it clearly, maybe I'm just slow but could anyone explain to me thnx!

Hubble constant is 70 km/s / Mpc.

Take the speed of light divided by 70 km/s and multiply by 1 Mpc.
 
hmmm ok maybe I wasn't clear of what I was trying to ask. I want to know how it relates to the inflation of the universe and the how the horizon is being affected during this major expansion. I don't want any calculation I just want to know the concept, but thanks for the Hubble constant calculation!
