A(z) Hubble Law kiszámítása
Mi az a Hubble Law?
Hubble law relates recession velocity to distance: v = H₀ × d. Foundation of expanding universe model.
Útmutató lépésről lépésre
- 1Input distance or recession velocity
- 2Apply Hubble constant H₀ ≈ 70 km/s/Mpc
- 3Calculate missing parameter
Worked Examples
Bemenet
d = 100 Mpc
Eredmény
v ≈ 7000 km/s recession velocity
Accelerating due to dark energy
Common Mistakes to Avoid
- ✕Using outdated Hubble constant value
- ✕Confusing recession velocity with proper motion
Frequently Asked Questions
Is Hubble constant truly constant?
No, changes with time; value reflects current epoch.
What is deceleration parameter?
Measures universe expansion rate change; negative (accelerating) recent finding.
