It's not hard

2019-07-13 00:20:52 UTC  

Didn’t you know it’s a true fact the Earth is round.

2019-07-13 00:21:01 UTC  

The stars move through the sky, sure. How do you know it's caused by our movement and not theirs?

2019-07-13 00:21:26 UTC  

Because I just do ok.

2019-07-13 00:21:43 UTC  

I didn't say they don't move

2019-07-13 00:21:52 UTC  

I said the distance makes it imperceptible to the human eye

2019-07-13 00:21:57 UTC  

Hence, they do not move perceptibly

2019-07-13 00:22:09 UTC  

Everything is in constant motion. Has been since the conception of the universe

2019-07-13 00:22:09 UTC  

So the earth is round

2019-07-13 00:22:33 UTC  

I don't think you get the gist of the question.

2019-07-13 00:22:48 UTC  

How do you know why the stars seem to move?

2019-07-13 00:23:10 UTC  

Because it's observable and mathematically verifiable

2019-07-13 00:23:22 UTC  

What is "it"?

2019-07-13 00:23:31 UTC  

The stars move and the earth spins around DUHHHH!

2019-07-13 00:24:28 UTC  

Here's an excerpt that gets the point I'm trying to make across much more effectively

2019-07-13 00:24:56 UTC  

There was no straightforward demonstration of Earth's motion until 1725 when James Bradley discovered stellar aberration. This is (apparent) yearly change in positions of all stars in the sky due to Earth's own motion. Aberration arises due to adding up of the speed of light coming from the star and Earth's own speed. This is a very complex phenomenon and its description requires some math.
Another, much simpler, consequence of Earth's motion is stellar parallax. If Earth changes its position relative to the stars, then the stars should appear to change position in the course of the year.
A common experiment illustrating parallax is just looking at a close object (a finger, a pencil etc) with one eye at the time. When you switch from one to the other eye, the object will appear to move against the background. Closer the object is to your eyes, more pronounced the effect is.
Parallax should not be confused with aberration: parallax arises from the change of Earth's position and depends on the distance to the star, while aberration is caused by Earth's great speed and does not depend on how far the star is.
Parallax of a star was first measured by Bessel in 1838. It was not measured before because this change of star's apparent position is very small (the stars are very far from us). This was a very important discovery because Aristotle himself mentioned the lack of observable stellar parallax as the proof that the Earth is not moving (he didn't have a telescope and didn't know that the stars are so distant).

Do you mean me

2019-07-13 00:25:04 UTC  

A third discovery demonstrating Earth's motion was that of Doppler effect. The wavelength of the light that we receive from objects moving relative to us becomes a little shorter (i.e. bluer) when we approach the source and becomes longer (i.e. redder) when we move away from the source. When Earth moves toward a star, the star will appear slightly bluer (only high-tech instruments can measure this) while it will appear redder when Earth is on the other side of the orbit and moves in the opposite direction. This effect demonstrates that Earth has a velocity relative to the stars, similar to aberration.

2019-07-13 00:26:00 UTC  

What is this about

2019-07-13 00:26:05 UTC  

Do you have an image of said parallax?

2019-07-13 00:26:11 UTC  

Nah

2019-07-13 00:26:42 UTC  

The parallax isn't something you can take an image of

2019-07-13 00:27:04 UTC  

Here's a graph that shows what the parallax would have to look like in order to be properly imaged.

2019-07-13 00:27:18 UTC  

Sure you can. Just take two photos months apart.

2019-07-13 00:27:19 UTC  

Wtf is a parallax

2019-07-13 00:28:16 UTC  

It has to be taken from an outside perspective or measured and graphed seperately

2019-07-13 00:30:02 UTC  

I'll put it in a very simple way

2019-07-13 00:30:09 UTC  

Do you have a picture of your brain?

2019-07-13 00:30:18 UTC  

Ayeeeeeeee

2019-07-13 00:30:59 UTC  

If not, then your brain must not exist

2019-07-13 00:30:59 UTC  

Ken like them photos when yer in yer mums tummy probably

2019-07-13 00:31:05 UTC  

See the pitfall in them logic?

2019-07-13 00:31:29 UTC  

What’s this about yuri

2019-07-13 00:31:51 UTC  

This is about showing the fallacy in the logic of "If you don't have images, it isn't real"

2019-07-13 00:32:41 UTC  

Do you hear laurel or yanny

2019-07-13 00:33:10 UTC  

I-

2019-07-13 00:34:03 UTC  

Do you see black and blue or white and gold

2019-07-13 00:34:27 UTC  

Are you honestly this annoying or are you just looking for attention?

2019-07-13 00:34:52 UTC  

I thought this was for debating

2019-07-13 00:35:13 UTC  

So did I, then you did a turnaround and changed it up so fast I got whiplash

2019-07-13 00:35:44 UTC  

Keep it on the subject. Don't ask arbitrary questions where a definite answer has been found or it has found to be a complete matter of opinion
