▁from ▁one ▁side ▁( A ) ▁of ▁the ▁object ▁to ▁the ▁other ▁side ▁( B ) ▁of ▁the ▁object , ▁they ▁would ▁have ▁to ▁rotate ▁their ▁hand ▁by ▁an ▁angle ▁" Y ." ▁Thus , ▁as ▁X ▁increases , ▁Y ▁would ▁decrease , ▁as ▁the ▁w rist ▁would ▁have ▁to ▁rotate ▁a ▁smaller ▁angle ▁to ▁move ▁the ▁las er ▁from ▁point ▁A ▁to ▁point ▁B . ▁Also , ▁correl ated ▁with ▁a ▁smaller ▁angle ▁would ▁be ▁a ▁decre ased ▁time ▁it ▁would ▁take ▁to ▁rotate ▁the ▁w rist ▁( it ▁will ▁take ▁a ▁shorter ▁time ▁to ▁rotate ▁the ▁w rist ▁a ▁smaller ▁angle ). ▁With ▁respect ▁to ▁distant ▁objects ▁like ▁the ▁moon ▁a ▁par ado x ▁ar ises ▁when ▁one ▁is ▁asked ▁to ▁hypoth et ically ▁move ▁a ▁las er ▁from ▁one ▁side ▁to ▁the ▁other . ▁Turn ing ▁his ▁w rist ▁half ▁a ▁degree , ▁a ▁person ▁can ▁move ▁a ▁las er ▁from ▁one ▁side ▁of ▁the ▁moon ▁to ▁the ▁other . ▁It ▁would ▁appear ▁that ▁the ▁las er ▁dot ▁is ▁trav elling ▁faster ▁than ▁light , ▁as ▁f lick ing ▁one ' s ▁w rist ▁at ▁such ▁a ▁large ▁distance ▁would ▁give ▁the ▁ill usion ▁that ▁the ▁object ▁was ▁able ▁to ▁cross ▁the ▁diameter ▁of ▁the ▁moon ▁( 6 0 0 0   km , ▁due ▁to ▁curv ature ) ▁in ▁mill iseconds ▁( Fig ure ▁ 2 ). ▁Based ▁on ▁subsequent ▁calculations ▁( distance ▁between ▁points ▁A ▁and ▁B ▁divided ▁by ▁time ▁it ▁takes ▁to ▁move ▁the ▁las er ▁from
