Cate miliarde de ani credeti ca va mai dura pana cand galaxiile se vor unii si vor deveni spirale triple?

Nu cred ca am putea sa scriem numarul ala de ani aici, la cat de mare este.

Se indeparteaza unele de altele din cauza expansiunii universului.

"As the universe expands, the galaxies get farther from each other, and the apparent velocity will appear to be larger for the more distant galaxies."
"The Earth and the Milky Way are not special in seeing that all galaxies appear to be moving away from us. If we were on a different galaxy, we would also see all the other galaxies appear to be moving away from us because of this expansion."

"Analizând lumina de la alte galaxii (vezi Efectul Doppler), Edwin Hubble a descoperit în anii 1920 că aproape toate galaxiile se depărtează de noi cu viteza V proporțională cu distanța lor R față de Pământ."
"Această observație importantă, cunoscută drept legea lui Hubble, a stabilit că Universul este în expansiune"

"Hubble's law, also known as the Hubble–Lemaître law,[1] is the observation in physical cosmology that galaxies are moving away from the Earth at speeds proportional to their distance. In other words, the farther they are the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit to the red end of the spectrum."
