First, you're assuming that people know things simply because they read what someone else wrote. That people, like me, are not actually out there
That, someone like me, can't use a telescope and measure parallax of a star over the years to help determine it's distance (what do you think they
did all those years before Hubble and WISE?).
That means you are assuming that I can't do math or trigonometry. That I don't know how to shoot the stars and verify declination and right
That Sirius, being not only the brightest stars in our skies, is also one of the closest and is wonderful for measuring parallax.
Not all knowledge is just from books. Where do you think that knowledge that is in those books came from?
From people like me that actually do those things.
Will everything be the same in 200 years?
No. No they won't, because like us, other stars are in motion too.
Our solar system takes 1,500 years to go 1 light year. In 200 years we will have moved 0.13 light years from where we are right now.
In 200 years, Sirius will be slightly closer to us, and that means slightly brighter too. In fact, in about 60,000 years it will be a LOT brighter
than it is now. Don't worry though, because it's path and the sun's path is different at after that it will spend the next 200,000 years moving
away and getting dimmer.
Will we discover new things out there in the next 200 years? You bet! With the rate of discovery that we've had over the last 150 years, I would
imagine we will discover many things. But there's a good reason we've discovered the things that we have over the past until now.
Ever since the Renaissance period, humans have been learning quite a lot. We actually created things like calculus, physical laws and how to put them
to use to discover even more things. We've gotten to where we know what we know now, because we were able to build upon that knowledge over time,
collect data over time, and increasingly being able to measure things even better and better over time.
You're able to post on this forum using an electronic media device not because someone said: Hey! Let's just throw out everything we know and make
up a bunch of new things!
No, you're able to post on this forum because we've be able to take things that we do know and keep building on them, and following the scientific
Sometimes "theory" becomes fact. And sometimes "Theory" stays as "Theory" because we can't prove that it's fact. And sometimes "Theory"
get's thrown out because there is a new, and better "Theory".
However, if you're going to change everything we know, then you'd better have something that can be proven......else it's not even a
theory.....heck, it's not even a hypothesis at that point. It's only wild speculation.
So....if you want our sun to orbit a star that is almost 400 light years away, and if you want that star in turn to orbit another star that is only
just over 8 light years away, then prove it.
All the tools are there. Math is not a theory. Trigonometry is not a theory. Calculus is not a theory. Certain physical laws are not theories anymore
either as we've been able to prove that they work, such as many parts of gravitation and orbital mechanics.
Don't believe that? Then I guess your GPS system and satellite TV system are working on "magic" instead.
The tools are there. Anyone can use them to either prove or disprove something. Or at the very least if some of you were to actually pick up these
tools and try to use them you might actually.................
