Is the Sun heavy or light?

>> No.16122768

earth avg density = 5,515kg/m3
sun avg density = 1,408kg/m3

1408/5515 = 0.2553

so 1kg of sun weighs roughly 250g. it's pretty light

Its nothing special isn't it. Or rather, the only thing that makes it special on many levels is its enormous size.

no, 1kg of earth takes the same space as roughly 250g of sun
the power density per m^3 is also very small

our sun literally outshines 80% of the stars in the universe and is on the larger side of the "stars that last longer than zoomer with chronic porn addiction" category (aka dwarfs, though this is an outdated term)
the nearest sibling stars to sol heralding from the same primordial dust cloud are theorized to be around 100-180ish light years away
binary systems are also not conducive to life

still 50 times lighter than a O star, and far lighter than a big BH

If want to compare by % then why not by total mass of each category? otherwise anything bigger than a boulder is 'huge' as most of the astronomical objects are microscopic.

the higher the mass of a star the more inefficient it is
the only thing high mass stars are good for (provided they don't just shit themselves into black holes) is generating heavy elements and even then you don't want too much of that in a universe as metallicity is stellar poison

>> No.16123131

>>16123069
It's what it's.
Talking about "efficiency" or "good for" is meaningless, even those stars are needed to get to something like the solar system, small-slow-stable stars are kinda useless, they're simply too quiet and slow. The large "inefficient" are the only causing some change in its surroundings but they barely burns more hydrogen than a smaller star. In the end efficiency, or good for is meaningless.

>the higher the mass of a star the more inefficient it is
Most starts are "efficient" because they're too small for faster fusion pathways that ends blowing stars up before burning most of its hydrogen or helium.

The sun is a little bit bigger than the Earth. Let's say for the sake of simplicity that the Earth weighs 1 big one. And the sun weighs 2 big ones.

Anything on the Earth that you might consider heavy, like an elephant, or a hammer, or a bathtub (filled with concrete) would have to weigh less than 1 big one, since the Earth as a whole weighs 1 big one.

By extension of this logic, anything you consider "heavy" would be lighter than the Sun, at least by a factor of 2.

kgf =/= kg
kgf lends to confusion, so N is better.

And if you meant "weight" instead of mass, things in the Sun weights nearly 30 times more for the same mass.

Only red dwarf stars below that critical 0.25 solar masses threshold, which is where they become fully convective and thus the most efficient (they burn the slowest and get to use pretty much all of their fuel).

We need to make every star into a 0.25 solar mass red dwarf for that reason. Either that, or we improve all stars by changing several constants of the universe so that the bigger the star the more fuel it can use and thus live even longer by remaining fully convective instead of this retarded programming we have right now.

Also, red dwarfs are not actually red. They're the actual yellow/orange stars in visible light.
