Augustus#0236: @Gooseman they know *less* than me about it now actually
Augustus#0236: @Hwaet how old did you think I was
Augustus#0236: most people IRL mistake me for a 17 year old because I'm tall
Gooseman#4440: dayum but im sure you can find a few good tutorials on internet

Hwaet#4348: I'm 17
Augustus#0236: My scope is far from perfect
Augustus#0236: the altitude boards aren't exactly the same height so the scope leans to the side a bit, really just an aesthetic thing
Augustus#0236: the front board is bent kind of
Augustus#0236: the tube is ragged on the bottom

Gooseman#4440: yh but if she doesnt know about that... 😉
Augustus#0236: uhhh she's seen them and looked through one
Augustus#0236: lol
Gooseman#4440: damn well if she bad at astronomy?
Hwaet#4348: that's teachable lel
Gooseman#4440: if she is you can always help her and spend time with he r;)
Augustus#0236: lol I'm no... |
Augustus#0236: which is part of my logic for giving her a scope - when she does have time she doesn't need me or anyone else to use one
Augustus#0236: I considered teaching her how to make her own mirror but that would take forever and I don't think it's a great idea to invite her to spend hours working with me in a ga... |
Gooseman#4440: christmas or birthday if its beforehand
Gooseman#4440: but honestly keep it till christmass till then get closer to her
Augustus#0236: oh wait her birthday is like december 9th

Razer531#0972: guys*
Razer531#0972: if 4.6 billions years ago or so, an object crashed into earth and its fractures later on formed moon, right? and that crash gave earth the spin, right?
Razer531#0972: If that's the case, shouldn't such a strike have created a noticable fracture on earth, like a hole or something we w... |
Qⓤⓞⓝ#1241: It's how Everest formed in the first place
SpaceGrandpa#6827: @Razer531 that's not why the Earth has its spin. You know how everything orbits the sun? Well, the first little piece of the Earth would have had the rest of the material that formed it orbiting that little piece. So everything was moving in a cir... |

Salt#1137: ^
SpaceGrandpa#6827: @Deleted User 785es519 you can also be aware of how your own power is supplied. See if you can find out how much of your electricity through electric companies is non-renewable vs renewable. If it's non-renewable, cut down on electricity use. Don't leave lights on in a room when you're n... |

SuchPain - Brent#4999: haha
SuchPain - Brent#4999: i think through light
Salt#1137: my first intuition is using type 1a supernovae, but that may be after his time
professor#7519: Through light?
SuchPain - Brent#4999: i dont know im bad at this.haha but that is what they are using to calculate the distance of galaxies.

SpaceGrandpa#6827: @Salt type 1a supernovae are used for stuff really far away
SpaceGrandpa#6827: I think we can still use parallax within the Milky Way
SpaceGrandpa#6827: And orbital speeds

AmalM#6443: @SpaceGrandpa
Razer531#0972: Guys why did people start using parsecs for distances? Aren't light years just good enough?
SpaceGrandpa#6827: @AmalM that just tells you how its perihelion is changing. Why would it tell you distance from the galactic center?

professor#7519: They aren't in my dictionary

Hwaet#4348: > parsec was defined as the distance at which one astronomical unit subtends an angle of one arcsecond,[1], but it has been redefined in 2015 to exactly
648000/π astronomical units. One parsec is equal to about 3.26 li... |

seba#8755: it's about stars, space, bunch of stars (galaxies), exploded stars (nebulae)
seba#8755: etc.
