It's not exactly rocket science is it?

Stellar parallax and measuring distance

Give us your view of the video'.

For those with inferior education, if you need to understand Paralax, you need to find out about Sin, Cosine, Tan etc. Once you understand them you will be able to calculate great distance in the sky.

If you are having any difficulties understanding a dose of this song may help some. When you find Lucy you will be just fine, that's where the marshmallow pie is

I can now play the Yorkshire man. When I went down t school we used to use a slide rule calculate things like you na what I mean.

For my SwineCunt uneducated ignorant as shit friends the Parallax angle is called Theta or some blommin Greek letter or other and when you use these letters and numbers you make something called an equation. The idea is if you know angle and a distance you can then work out the unknown distance. While you are at it you may as well learn about Pitagoras too.

Unless you studied Maths, Physics and Chemistry at A level, do not look at this clip. It will your mind.

Wait and see what my SwineCunt friends do when they read about who feasts who in space. Shiiiiit man this must be mind blowing for them.

Astronomers in Armagh have discovered a sign that a star feasted on nearby planets and asteroids.

A metal scar found on the dead star's surface has never been seen before, said astronomer John Landstreet.

What's rocket science is not the parallax phenomenon itself (discovered by the Greeks), but the means to measure the angle of the shift.
That's the reason it took astronomers centuries to do the first nearly correct measurement.
For a start the angle is miniscule and in no way even close to what the video shows.
Every degree of an angle has 60 minutes and each minute has 60 seconds .A total of 3600 divisions. These divisions are called arcsec. We say that if a planet has a parallax=1 arcsec, then it is 1 Parsec away. Parsec means Parallax -arc-second.Google it to find out how many AUs or Km it is.
The parallax shift of the nearest star -from memory- is only 4 such divisions (arcsecs), or is it 0.4??

Now find me a telescope strong enough to see such shift, and an instrument accurate enough to measure it. :wink:

Unfortunately even educational media often provide false/misleading information on the most basic things concerning the Universe. Look how they present our solar system:

Britanica here gets the sizes correctly but not the distances.
https://www.britannica.com/science/solar-system

National Geographic gets them both wrong
https://education.nationalgeographic.or ... tal-plane/

and the vast majority of the images available everywhere show the orbits as highly elliptic when in reality they are very close to perfect circle.

Now if you are interested to learn the reality take a piece of paper and draw a circle
having 109 mm diameter. That's the sun. Then go to Sultan Erdogan's palace, move 4 bedrooms way and draw a circle having 1mm diameter. That would be the Earth. From there move another 16 bedrooms away and draw a circle having 11 mm diameter. That would be Jupiter....

Our solar system is actually dominated by the sun.
The rest is just dust, scattered around.

It is indeed mind boggling. I am about to put something about distances and degrees of shift, surely we are able to measure 1 nanometer which is 1 millionth of a millimeter. I am sure a smaller unite will be measured especially with the use of AI. We are living in interesting times.

By measuring the position of the stars every six months and exploding supernovae they can measure to stars which several billions of Light years away so it can only get better as instrumentation improves and they identify alternative measurable objects in space.
