...find the angular width of the pencil, in minutes of an arc.

Please show your work because I am having a lot of trouble understanding and figuring this out. Thanks a whole lot!

I'm wondering what's on the other side of the sun and above and below, and it's a lot of plausible theorizing on space and time.
Sorry to sound stupid, but please enlighten me on any theories

When I was growing up in the 70s in Michigan, I could remember jets breaking the sound barrier all the time and our house shaking from the sonic boom. I used to really think it was interesting and fun. My family did too. Weird since it made some people angry. Since then (except when I happened to be in Orlando when a shuttle was landing) I have never heard this and my parents who still live in Michigan, say they don't hear them any more. Are jets restricted from breaking the sound barrier now or is a fuel cost thing or what? Thanks.

I read somewhere that Jupiter originally started out becoming a star but ended up as we know it today. Has anyone else heard about that? Do you know any good sources so I can read up on this?

not necessarily just the galaxies, wouldn't the limited speed of light mean we can never reach the edge, especially with expansion having a huge headstart.

I think that time is only now and you can not measure it, you simply can not travel back just like you can not travel to the future. It's either now or in your memories/prognostications

Please correct me if I'm wrong
thanks

because, if the stars are travelling away from each other then surely they must have started from the centre all together and some force pushed them to move away from each other. however many say this dont make sense, why?
