/ means "and" or "or"

In urs it means or ?

U can’t do the scientific method without experiment bro

it's an experiment if you have control over the parameters, but it's less of an experiment and just observation if you really have limited control

I mean, that's my understanding

I'm just telling you what I undesrtand about it

i'm no expert at this though

Ok

If u just have observation that’s not experiment

if you're going to measure something that is already in nature, I would call it an observation and not an experiment

U have to manipulate the iv in an experiment

U can just observe an experiment though

Can’t

and in both cases, you need to make an observation (or more accurately a measurement) in order to collect data

@jeremy yes you're right, and Riley did not

Therefore his conclusion is wrong

Ok

U brought it to him and he said what ?

I don't think anyone has ever measured the distance of stars

He flipped out and said go away

Hey haven’t lol

He couldn't reconcile being wrong

"scientists" have only calculated the distance by using the hubble law (for far distant stars) and *maybe* some triangulation (I don't really know) for nearer stars

@SunRazor stellar paralax

@RogueReflector be careful, don't start name calling

yea stellar paralax

either way, it's calculating using models

I don't think we can really measure the distance to stars

That's based on measurements

U need to know the size of something or the distance to it to find out the one measurem t u don’t have

the measurements that are made, I might not doubt their accuracy... but it's the models used that I question

@jeremy ya, that's not true

You can do it with two angles and a distance

stellar paralax? fine, I can accept that. But the hubble law is founded on assumptions

The red shift thing?

yep

Ya I gotta read about that

I think it's corraborated in another way

Like the size of the objects has certain things going on

If I cut a circle out of cardboard go@in a field and u don’t know how far away I am I can tell the size of the circle ?

Yes,
