Not the Earth-Sun barycenter. It's always about 450km from the center of the Sun. Each pair of bodies has its own barycenter. So if you have a lot of bodies things can get complicated because they all wiggle around as a result but the Earth-Sun barycenter is always well inside the Sun.
The center of it never leaves the suns corona. But it does leave the photo sphere.
Yes because it makes the star "wiggle". But it takes a large planet to make it wiggle much.
It is also how they found planets around other stars.
Yer right.....the system is composed of just Earth and the sun with no other influences... Our system is composed of more than an Earth and Sun....

If everything was just 2 bodies, then you would be correct. But in real life, it isn't so..

In real life there is one Earth-Sun barycenter.
In real life the other planets do not "wiggle" the Sun enough to move the Earth-Sun barycenter from the interior of the Sun.
see above..

I'm quite aware of what a barycenter is.
Still waiting for you to provide an example of the Earth-Sun barycenter (because that's the one we're talking about, right?) being anywhere but the interior of the Sun.

Why does anyone else need to know the behavior of the sun relative to the earth? (to be honest it doesn't come up in daily conversation very often)
Half the population not "knowing" that we evolved from animals probably doesn't take into account that almost half the population will have a religious basis for not believing we evolved from animals.

A couple thousand people hardly speaks for the entire population.
Think about it; America is actually smart enough to take over the world!
- wouldn't you agree?

The theory that humans evolved from animals is only a theory, but these statements from the source are inserting that in as a fact commonly known, and to me that means "agenda" ..
But it's true about people not knowing a lot of science facts.. When I was a lot younger, (a long time ago), I had a friend who thought the stars in the sky were just some type of light thing.. He resisted and scoffed when I told him they were other suns. Pretty funny, I still laugh at him because he is still just as dumb now than he was then..
Space science especially seems to be the area of knowledge that the common person doesn't know anything about, and many don't even care..(I don't understand that stance at all)..
Are you suggesting that humans have not evolved?
Are you suggesting that the difference of less than 2% DNA-wise between human and apes is unimportant?
No, not at all. What I was pointing out is how the author of the linked article was communicating it, and how it is dripping with an agenda.. I see it, but I'm not saying everyone has to see it that way..
Are you suggesting that the commonality in DNA between humans and all other animals in existence is just coincidence?
Just wonderin..
I don't believe in big coincidences like that. Biological life here shares many, many commonalities. A natural process of evolution is apparent, and this doesn't mean there can't be a creator. This is the agenda that I sensed by the way the author worded his statements, made to look like it was denigrating people that believe in a creator. like evolution somehow would destroy that notion... It doesn't. I'm left wondering if the author is like those he is implicating. It's one thing to learn true scientific information, and quite another to learn from people with an agenda in one form or another.

You have not demonstrated that the Earth-Sun barycenter is ever anywhere but the interior of the Sun. It isn't. It is always inside the Sun.
