Is the Hertzsprung-Russell diagram still a valid instrument in studying stars, given that it is over 100 years old? and why?
Answered by MA N I A
The general evolution of stars is still as it was propsed back then. It's similar to why the periodic table is still used when it was first proposed in its current format back in about 1875.

I ment to say proposed, not propsed. Sorry.
