Modguy: Fairly sure that was added merely to illustrate the point, and to help visualize the mechanics.


Kinda ballsy though to claim the heliocentric model is wrong, and then show a new model of the Solar System with such a huge error. Also, image was missing the distinct wobble the Sun should have relative to Jupiter, their barycenter is outside of the Sun.

Boojum2k: I think we'd notice the Sun emitting a light-year long jet from its South Pole.

The Solar System is moving due to gravitation, not thrust.


It also doesn't move perpendicular to the ecliptic plane, but the guy who made the video "doesn't buy into that".

Alrighty then. Never let the facts get in the way of your creative epiphany, then.

Let's see, the Sun and planets are moving through space while the planets orbit the Sun.

Nope, that pretty much matches exactly with what I was taught in 3rd grade.

A: it's "heliocentric", not "helical".

B: This is something I've known since grade school, it's just a good visualization of it. The plants still revolve around the sun, they just do it while also travelling laterally through space AS A COMPLETE UNIT. It's not like Suddenly they are revolving around another body, it's still the sun.

Glancing Blow: So if I read you correctly, the course of the galaxy is the direction at that instance in time resulting from the gravitational fields of all surrounding bodies.


No -- gravity is not pushing everything apart. We're not sure of the details on the force responsible for this and we're calling it "dark energy" for the moment. Not to be confused with dark matter, which is what we call the force responsible for orbital mechanics of galaxies not behaving the way we expect them to based on what we can measure.

Don't think of our galaxy as traveling a path; travel can only be measured relative to reference points, and the only reference points we have are other galaxies. And they're all moving away from us. And if you're in one of those galaxies, you would see all the other galaxies moving away from your galaxy. It's not that the galaxies are moving through space so much as the space between them is increasing. And since we can only determine the distance based on our observations, you could just as well say that light from those other galaxies took longer to reach us today than it did yesterday, and that tomorrow it will take longer than it did today by a larger factor. Hence, acceleration. Eventually, it is hypothesized, the speed at which the space between galaxies will be expanding so quickly that light from other galaxies will never, in an infinite future, reach our galaxy.

Not all set down as indisputable fact quite yet, mind you, but that's what the data is telling us these days.

Glancing Blow: OK, but I know I've been told that the galaxy is moving and that it's (still) accelerating. If not from some origination point than what is it's path?


In short: away from everything else.

The big bang wasn't an explosion into space so much as an expansion of space itself. If you call any point in space "the center" and measure the acceleration of other objects away from it, the model holds. It holds no matter what point you pick and say "this is center".

I never knew Saturn had a closer orbit to the Sub than Jupiter. Hundreds of years of astronomical knowledge being turned upside down.

Or the Soloar system can be pictured as being completely motionless in a general directional axis in space with all other objects having motion relative to our stationary solar system. which would mean that from a non-linear non-subjective point of view.. sorry got off track a bit there.

What I mean is that with no absolute motion in the universe on a macro scale the simplification of thinking of the Sun as a fixed point about which the planets rotate is just as correct as whatever that swirling mess was in the video.

And since "helical" actually means spiral, subby is extra bonus dumb

I was thinking the same thing. As soon as I saw "Life is Vortex" I was thinking someone was educated stupid.

Except our solar system is not traveling in a straight line. It is orbiting the center of our galaxy, which itself isn't stationary. It's all about your frame of reference. However, it is interesting because the solar system with the sun being the stationary point of reference is usually the farthest out depiction that us laymen usually consider, so you can tend to forget that the whole thing is also moving quite fast through space.

In other words, Just remember that you're standing on a planet that's evolving and revolving at nine hundred miles an hour...

Really, this video is "wrong" for the same reasons it claims the standard disk model is "wrong".

The sun does not travel in a straight line, it orbits the galactic center while the galaxy itself is shooting through space and may itself be orbiting something even larger (see Dark Flow). If the disk model is wrong because it looks different when you pull back the frame of reference, then his vortex model is wrong when you do the same, because his perfect little vortex starts bouncing around the universe like a superball on crack.

I'm fairly certain a bong played a large part in this.
