How would one use hubble's law to find the redshift of a galaxy[itex] 10^10[/itex] light years away? (in other words [itex] 3*10^9 pc[/itex])
All I know however is the version of hubble's where [itex] v=H_o d[/itex], with [itex] H_o=71 \frac{m}{s*pc}[/itex], which tells me that [itex] v= 2.2*10^11 m/s[/itex]. But this violates the second principle of special relativity!
How do I get around this problem?
