Jaime Rudas replied to the thread Undergrad Does the scale factor need to be normalized?.Because for calculating the particle horizon, it's not relevant to know how many times the universe has expanded since the Big Bang... -
Jaime Rudas replied to the thread Undergrad Does the scale factor need to be normalized?.Yes, we can't.

Jaime Rudas replied to the thread Undergrad Does the scale factor need to be normalized?.I will try to clarify my previous answer: the model does not include the moment t=0 because a singularity occurs there, that is, an...

Jaime Rudas replied to the thread Undergrad Does the scale factor need to be normalized?.No, the model doesn't assume that. Where did you get that from?

Jaime Rudas replied to the thread Undergrad Does the scale factor need to be normalized?.I agree. Thanks for clarifying.
-
Jaime Rudas replied to the thread Undergrad Does the scale factor need to be normalized?.Since the scale factor was 0.5, it has doubled; since it was 0.1, it has expanded tenfold; since it was 0.01, it has expanded 100 times...

Jaime Rudas replied to the thread Undergrad Does the scale factor need to be normalized?.I'm not sure I understand your point correctly, but it seems you might be confusing the expansion rate with the particle horizon growth...

Jaime Rudas replied to the thread Undergrad Blueshift in case of the Big Crunch scenario.No, that doesn't follow from what Wikipedia says. Wikipedia states that the FLRW metric is used to model the expanding universe, but it...
