Why is a fairly thick protogalactic cloud most likely to produce an elliptical galaxy than a spiral nebula?
Why is a thick cloud most likely to produce an elliptical galaxy than a spiral nebula? The greater gas density forms stars more effectively so all the gas is transformed into stars prior to a disk can form
Why should galaxy crash have been more typical in the past than they are today?
Why should galaxy crashes have been more typical in the past than they are today? Galaxies were better together in the past since deep space was smaller sized … Such galaxies produce a lot light that they would have taken in all their gas long earlier if they had actually constantly been forming stars at this high rate.
Which kind of protogalactic cloud is more than likely to form an elliptical galaxy?
3) A protogalactic cloud with really little angular momentum is most likely to form an elliptical galaxy than a spiral nebula. 4) Galaxy crashes were more typical in the past.
Can telescopes see back in time?

What is evidence that deep space is broadening?
American astronomer Edwin Hubble and others found in the 1920s that deep space is broadening by revealing that the majority of galaxies are declining from the Galaxy— and the further away they are the faster they are declining. The approximately continuous ratio in between speed and range ended up being referred to as the Hubble constant.
