This is the reason why we do not simply fall into the sun because we are spiraling toward it because of the bending in the fabric of space that creates a 'pocket' or 'pucker' where things inevitably desire to fall, but this possibility is resisted by the motion of the star itself. If nothing was moving than gravity would gobble up anything it encountered because it is an actual BENDING of spacetime.

@SPrinkZ That was so breathtakingly ignorant, I'm not even going to attempt to correct you. Just go to your local community college and sign up for a course in basic astronomy.

And you're right--we aren't moving. We're more like on a soap bubble just expanding. But it seems like movement.

I didn't articulate it properly--but the animation isn't really wrong. It's just a different POV.

It's the 21st Century and we're only now being told this!? It's a wonder we don't drag all sorts of crap along with us.

There's as much truth in this video as there was in the mayan calendar doomsday predictions.

And no SPrinkZ, stuff in the universe isn't moving away from "the point of the big bang". As far as we know, the universe iiself was that point; there was no empty space around it. Matter isn't moving away from a fixed point in space.

I also suggest you read up on orbits, unless I misunderstood your other comment.

We are not being dragged. The earth has the same vector through the galaxy/ universe that the sun has, notwithstanding the orbit around the sun. But yes, the overall model is correct.

Everything in the universe is moving away from the point of the bigbang--or the singular event that caused time and space to...I guess begin. It's amazing how misinformed people are about the cosmos.

Incidentally, Cosmos is a great series to watch by Carl Sagan if anyone is interested in learning about some rudimentary things about the universe they have inhabited so seemingly coincidentally.

Wow this is genius! We all know that we revolve around the sun, but who would have thought that the sun might be moving too? Frickin' brilliant, I can't believe nobody thought of this before! In the old days people thought that the earth was static in the centre of the universe, and then we learned it was the sun that was static in the centre of the universe, (didn't we? no? oh.) and now get this, the sun might not be either and it too is on the move! Well go to the foot of our stairs.

Also--space isn't a perfect Vacuum if I'm not mistaken.

OldOllie...you are frequently the most misinformed poster here I'd hope you know...The sun's 'tail' is being used as an example to show the movement of the sun through time, and the path that is shown is purely relative. This is the reason why we do not simply fall into the sun because we are spiraling toward it because of the bending in the fabric of space that creates a 'pocket' or 'pucker' where things inevitably desire to fall, but this possibility is resisted by the motion of the star itself. If nothing was moving than gravity would gobble up anything it encountered because it is an actual BENDING of spacetime.

I recall a theory that time travel is easy: BUT since the Earth is constantly moving, you have to BE where it WAS in order to travel in time and survive! Miss by 100 feet? DOOM!

Right! If you're not careful, you could end up in a ghetto.

This is so wrong on so many levels. First, the direction of the sun's travel in the galaxy is at an angle of ~40 deg. to the ecliptic, not perpendicular to it as shown here. Second, the sun isn't "dragging" the planets along with it. That implies a resistive force to drag against. Were all moving along merrily together. Finally, the image of the sun leaving a tail behind it was totally ridiculous.

My advice to the idiot who made this: I'm sure you did quite well in art school, but you really should take an astronomy course before you put your ignorance on display like this again.

It's especially interesting to consider that time flows differently depending on our speed and the location of the earth in orbit around the sun relative to the location of the sun in orbit around the center of the galaxy.

@5Cats,
"Oh look, the Sun's moving too!"
------------

Yes, but so is the solar system, so is the galaxy... Motion is a relative thing.

@patchouly: Well it's not THAT dramatic, I hope! More like the sun inches along and the planets MOSTLY go in circles (elipses) around it, dragged slightly forward because the sun is moving.

They exaggerate the motion, like they've exaggerated the size & positions of the planets. (they're WAY too close to the sun, we'd be on fire!)

I think the point is just to say "Oh look, the Sun's moving too!"

Let me rephrase that...Motion is relative.

But 5Cats, there is SO much more to it than that. This isn't a helical system anymore than a bullet dropped from an open hand while in a moving car is the same a a bullet fired from a gun.

Nice! It's true: the Sun is zooming through space & we're along for the ride, like it or not!

Obviously not to scale: if the Sun were that teeny the planets (including Jupiter) would be specks.

I recall a theory that time travel is easy: BUT since the Earth is constantly moving, you have to BE where it WAS in order to travel in time and survive! Miss by 100 feet? DOOM!
(It only works to go back, because forward time hasn't happened yet. Thus you could go back in time, but never return to "the present" eh?)

well this is also an inaccurate interpretation of our solar system. The planets orbit the sun on near the same plane as our galaxy and therefore it is not a vortex. It’s a solar system moving together through empty space around the galaxy center and it is not a torpedo as interpreted here.

Interesting. I enjoyed it with the sound down.
