and explains why the pattern exists

Just do what every other astronaut done

how is it accurate if it's based on incorrect information

So why does NASA say the Earth is flat?

A lot of people grasp at the first model they see that SEEMINGLY fits everything

Of course it works perfectly if you ignore the little flaws and adjust data to fit the model in other parts

@SamanthaFluff ya, that's not done

none of what you said is done

ephemerides are generated using gravity spherical earth, heliocentric model

Also note that this document assumes that a helicopter is a rigid body. Which is not true.

and they predict the ground track perfectly

@MCToon flatties never heard of simplifying assumptions

How do I double check this predicted ground track?

@SamanthaFluff check recent ground track of US 2017 eclipse

@Meeper Agreed. As an engineer, I must do that daily.

I was there, right on centerline, and the duration matched prediction perfectly

ephemerides is pattern recognition, based on ground observed data, not based on heliocentrism

had an app on the phone

@Meeper I've observed the eclipse myself in Salem like many before me did, even before we had any of our modern science :D

@Human Sheeple prove it, b/c this says differently : https://en.wikipedia.org/wiki/Jet_Propulsion_Laboratory_Development_Ephemeris

@MCToon awesome, what type of engineer are you?

@Human Sheeple not based on any pattern

it's time stepping the n-body equations, using newtonian physics

i take 75g of creatine everyday

@SamanthaFluff the pattern of occurances doesn't tell you the ground track of the shadow

and the pattern doesn't work for the whole earth

You know JPL used to be Jack Parson's Laboratory and he used to hang aroudn with Crowley doing satanic orgies with cartoonist Disney, Nazi war criminal Von Braunn. You know Jack Parsons even gave missile technology to racist apartheid state Israel.

@Human Sheeple yet you cite nasa when they say they use the saros cycle to predict eclipses

@Meeper the ground tracks have a pattern to them lol

@Human Sheeple prove that image isn't a painting anyways

No I cited NASA admitting Earth is flat and non rotating

@SamanthaFluff ok show me what pattern predicts this

Plus the ground tracks listed by NASA aren't necessarily reflective of what happens in reality

@SamanthaFluff gonna have to back up that last statement

If NASA tells you the eclipse happens in this specific area, how do you verify it's not happening outside of that claimed area

b/c thats patently false

records of eclipses, same ones you talk about

agree with this method perfectly

@Meeper for starters, they are all plotted with globe earth being assumed as a given :P
