First round of my answers:
0:28 ... but I know that the closest stars to Earth (other than Sol) are a little over 4 light years away.
Oh. You do. You took a space craft that travelled at speed of light, it took you four years to reach Alpha Centauri and four years to get back?
No? Wait, we don't have any space craft that travel at the speed of light!
OK, someone else did with somewhat slower engine? Vasco da Gama?
No? He was perhaps more involved with roundness of Earth, wasn't he?
But what about Starship Enterprise ... wait, you mean that is FICTION?
OK, that means you do NOT know this by travelling back and fourth.
0:35 Assume the orbits of these stars are circular
They should be very close to that for the daily movement.
These equatorial stars travel
Was Alpha Centauri equatorial or were the "four light years" at some diagonal?
C = 2pir
[roughly equals] 24 ly
1:09 [The star travels] 24 light years in 24 hours.
Supposing they are that far away in the first place, as the 4 ly presumed. Plus supposing it is equatorial. IN fact, Centaur is completely visible from 30° N to 90° S. I e it is not equatorial.
Plus, very small quibble, the stellar day is a few minutes shorter than 24 h, an hour being a 24th of a Solar Day [and not of a Stellar one].
If the stars were travelling at light speed, they would only be able to travel 24 light-hours in 24 hours, NOT 24 light years.
OK, what if the real daily orbit is much closer to 24 light hours than to 24 light years?
This would of course mean the 4 light years are false as distance, but you haven't proven them by travel, however you think you did prove them.
1:22 You calculate that IF they were 4 light years away (however you checked that in the first place), they would be travelling 8760 times the speed of light.
And if the distance is shorter, the daily speed is of course much smaller.
1:38 The vast majority of stars are much further than 4 ly from Earth
"If you say so". Or, BTQAW?
1:47 Considering equatorial galaxies.
Supposed to be, nearest, 2 million light years away from earth etc. ...
- 1) Do you KNOW as a fact that stars group in "different galaxies" and that
- 2) the nearest of them (probably thitherto called a Spiral Nebula) is 2 million light years? Etc.
Let's not be ridiculous about Han Solo, you saw it in a crystal ball!
No? You don't believe in crystal balls? Fine, neither do I.
2:01 We're not trying to prove anything.
Fine, because if you were, you would be leaving too much out. Taking too much for granted.
2:33 Trio Sonata for Flutes and Piano, in A Major - I. Largo. Emily Stark performed Georg Friedrich Telemann.
For once a really substantial info!
Now, would Telemann have accepted:
- Alpha Centuari being 4 ly away?
- Spiral Nebulae being "galaxies like our own" and hence comparable in size and hence very far away, like 2 mill ly.
How would you go about explaining those queries to Telemann.
Han Solo might help, until he asks if he's for real.
Posting this before I know if there will be any more rounds.
At the very least you get good music, and I am preparing you for what I consider a fallacy.
