if you believe science

How accurate is it?

Exact.

What all does it predict?

its one of those things they would have on ships or whatever

its not exact

@Derek Nelson didnt you just say we couldnt measure bodies in space exactly?

"I assure you, nobody has actually measured distances or sizes of celestial objects. It’s all theory."

Then how did the astrolabe work?

How were they able to predict this stuff?

If they couldn't measure it, that is?

That isn’t measuring their sizes or distances. It’s simply predictability in movement.

The shape of the straw is not the same as the shape of the nozzle.

There's less of a surface area for the air to push the vehicle forward

Yeah sure whatever

Lol.

Such shit

@Human Sheeple didnt someone just send you a link of rockets working in a vacuum a while ago

and you ignored it

Why is that not CGI, but NASA's photos are?

@tripolarbear post it up please

that experiment is inconclusive because its not done well enough with the rocket

a running fan will not move a feather in a vacuum

shows why rockets don't work in a vacuum

Those are two different scenarios

same

No, they are different.

rocket uses propellant to push off gas

@tripolarbear Let's have a look

with nothing to push off, rocket doesn't move

A feather and a rocket are different in their composition and structure.

if you want evidence on why rockets work just fire a gun you live in the us right?

they both use air to move

and just change the density of the projectile

A feather is made up of a bunch of loose parts while a rocket is one solid object.

eg a heavyier bullet

running fan is using air to push a feather, move it
