Stimbo, can I collect my winnings now?

Certainly. Don't forget my 10% commission.

Why does the age of light matter? As long as it still works it's fine with me.

Maybe it's irrevelant with your belief. Do you believe the universe is also very young? If so, then my point was that the light we see from stars is sometimes billions of years old.

I only took 1 astronomy class. They said the universe was about 15 billion years old by measuring Doppler shift (or something like that). I just went along with it at the time since that's what they taught us. I never really thought much about it nor did I even know that people actually believed in a young earth at the time. To be honest I never actually thought to question science (or really anything else) when I was younger.

Yes, the Doppler Effect helps us account for the fact that the universe is expanding. Otherwise we wouldn't be able to tell what the true distance of the object we're measuring is, and hence how long the light has been travelling.

The universe is 13.7 by according not only to redshift, but also by several other things such as the age of white dwarf stars. As with the age of the earth, there are multiple lines of evidence.

Well it was about 15 billion a few years ago (I have the textbook). But we talked about all that. Heck I still look at the sky at night to recognize certain planets because of that class lol.

Sorry I just realized I didn't answer your question. But yes I do believe that the universe is young.

Yes, some years ago it was thought to be older, due to some inaccuracies in measurements and such that have since been resolved.

How old is your textbook? It's been several years since the 13.7 by figure was established. As in many.other disciples, in astronomy it's important to use the most current data.

IDK I took the class a few years ago. It was the newest at that time. It's not really that important though.
