Mwanga Mwekundu Kutoka kwa Galaksi za Mbali Unatusema Ulimwengu Unapanuka

Stephen Hawking: The red light from distant galaxies tells us the universe is expanding

[Scroll down for the English]

KISWAHILI

“Nilikuwa nimesikia [hapo ujana wangu] kwamba mwanga kutoka kwa galaksi za mbali ulihamishwa kuelekea mwisho mwekundu wa masafa na hii ilipaswa kuashiria kwamba ulimwengu ulikuwa unapanuka. (Kuhamishwa kuelekea rangi ya buluu kungemaanisha kuwa ilikuwa inapungua.)

“Lakini nilikuwa na uhakika lazima kuwe na sababu nyingine ya mabadiliko hayo mekundu. Labda mwanga ulichoka, na umekuwa nyekundu zaidi, njiani kuelekea kwetu. Ulimwengu usiobadilika na wa milele ulionekana kuwa wa asili zaidi [kwangu].

“Ilikuwa tu baada ya takriban miaka miwili ya utafiti wa Shahada ya Uzamivu (Ph.D.) ndipo niligundua kuwa nilikuwa nimekosea." [Utafiti wa Hawking ulifunua kwamba ulimwengu ulikuwa unapanuka.]

ENGLISH TRANSLATION

“I had heard [in my youth] that light from distant galaxies was shifted toward the red end of the spectrum and this was supposed to indicate that the universe was expanding. (A shift to the blue would have meant it was contracting.)

“But I was sure there must be some other reason for the red shift. Maybe light got tired, and more red, on its way to us. An essentially unchanging and everlasting universe seemed so much more natural [to me].

“It was only after about two years of Ph.D. research that I realized I had been wrong.” [Hawking’s research revealed the universe really was expanding.]
