Hiyo naifahamu...okay nawewe kasome kama jamaa alivyokushauri kwanini galaxy za mbali zinatuacha kwa speed faster than C...hiyo ni fact (from observation)
Ni hivi; hapa hatuzungumzii relative motion between Galaxes, tunazungumzia motion of Galaxes in relation to centre of the big bang. The big bang ndio kitovu cha reference nacho kinahesabika kama a fixed point na speed ya any galaxy in relation to the point can never be equal to "C".
Ukizungumzia juu ya relative motion between galaxes hapo unaweza kuwa sawa kwani mfano, kama Galaxy A ina move kwa speed X m/s close to the speed of light "C" in relation to point of the big bang and reversely Galaxy B moves at the same speed of x m/s, relative to the same point, therefore the speed of Galaxy A relative to Galaxy B➡x- -x=2xm/s.
2x m/s which is greater than "C".
Mimi sikuongelea kitu hiki bali nilongelea speed ya galaxes heavenly bodies relative to the point of the big bang CAN NEVER be equal to "C".
