The first video in a series detailing how we measure distances in space and so explore the origins of the Universe. Explaining how nearby star distances are measured using the technique of trigonometric parallax and what the limitations are.

If possible pls continue the videos on cosmology. It is really helpful indeed.

How long do the rest of the videos take?

There is no parralax in the stars from earth, scientists claimed to have seen parallax from a spaceship that took photos after lining up to 50 other stars. As for finding the distance, size or speed of any bodies in the solar system/galaxy/universe, one would need to know at least the distance and size of at least 2 of said bodies. No one seems to be able to explain how they come up with the first distance of a planet without knowing any other distances.

What are you yapping about

@biggusdickus6436 Жыл бұрын

you have no clue how you saved me for my exam in 2 days, didnt understand parallax well but now i do and im going to see for the doppler effect and luminosity and a few more things... pls wish me luck ;-;

Is it necessary to convert to Au or can we keep them in Km?

@nutshellphy 2 жыл бұрын

You can keep them but you need to know about AU. And pc.

how do we measure the angle tho? the one you divided by two to find the parallax angle

@nutshellphy Жыл бұрын

That’s measured by how the near star has moved against the background. If you think of the sky as 180 degrees you can see where it was and where it is 6 months later.

6:10 I did not get this part, how did we get the 1.5° here If, 1 second = (1/3600)° 0.75 seconds = 0.75×(1/3600)° 0.75 seconds = (2.083×10^-4)° Am I right?

he meant 1.5" total between summer and winter equinox

Can I get source of your data?Wanted to write an article actually

@nutshellphy Жыл бұрын

Source of which data? The star stuff? Oh that was from multiple places sourced over a few years, I couldn’t tell you exactly where from at this stage. Sorry. But you can probably find similar data on any decent astronomy page.

Actually wanted to know about the limitations of trigonometric parallax .100 parsec/1000 parsec?

How do you measure the parallax angle? I watched some of these videos, and no one has mentioned how to measure the angle. Anyone with a high school math knowledge knows how to solve a right triangle, it doesn't need tutorials.

@nutshellphy 11 ай бұрын

This is for high school students. Hence the ‘tutorial’.
