Yes, there are limits to parallax methods in measuring distances. The accuracy of parallax measurements decreases for very distant objects, as the angle of parallax becomes very small and difficult to measure precisely. Typically, parallax is most effective for stars within a few hundred light-years from Earth; beyond this range, other methods like standard candles or redshift are often used to determine distances. Additionally, factors such as atmospheric distortion can also affect measurements near Earth.

Why can smaller parallax angles be measured by telescopes in Earth orbit?

Earth's atmosphere does not limit a telescope's resolving power.


Should there be a limit to methods revolutionaries employ?

There should be no limit to methods of revolutionary status. This is how we progress in science and in technology.


How or with what do people measure a light year?

This can't be measured directly (as in, applying a measuring stick), so the distances are calculated in other ways. Several methods are used; for a start, for nearby stars, the star's parallax is measured. The smaller the parallax, the farther away the star is. Parallax is the apparent change in position, of a star, compared to the far-away background, as Earth moves from one side of its orbit, to the other.This can't be measured directly (as in, applying a measuring stick), so the distances are calculated in other ways.

Is parallax a star?

The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
