So there is a gravity well toward the centre of our star system. So Venus and earth which are about the same gravity should be in the same orbit rather than Venus being closer to the sun. So why is earth father from the sun? How about because gravity of Venus (Gv) is not like gravity of earth (Gvenus-Gmoon=Gearth). The moon is exerting an antigrav counterforce on earth reducing its gravity so it is further out of the gravity well of the sun.
If this is so we can take phobos from Mars orbit into mercury orbit to become the moon of mercury and exerting an antigrav counterforce cause Gmercury to become Gmercury-Gphobos. So moving mercury out to Venus orbit and turn mercury into the moon of Venus means Gvenus becomes GVenus-Gmercury which will move Venus out to where earth orbit is.
Having done this, the sun will sit deeper into the galactic gravity well because the Gsun was subjected to the counterforce of mercury as its moon.
So Gsun-Gmercury becomes Gsun. So the sun changes direction and any alien civilization capable of noticing will realize we are here.

Venus *has* to be moving faster in its orbit than the Earth. [Check out
Kepler's stuff for some terminology.]
But, let's use your universe, if the planets all had equal tangential
velocities and the Solar System still moved and looked the way it
does. Then, we would need *different* laws of Physics.
What do you think a model of these different laws would look like?

I dunno that we want to try piloting our solar system. What if the guy behind the wheel is drunk? Can you imagine the fines for drunk driving of a solar system? Our insurance rates would be galactic!
I just spent fifteen minutes with Skyco and saved fifteen percent on my star insurance. Woooooow.

"Capable of noticing" would be true of any achievement. Radio waves, increased thermal energy due to industry, atomic weapons, etc. Yet suppose thee is an alien civilization looking out for any signs of solar systems doing a square dance?
Now they have to decide what to do now that another civilization can rearrange galactic mass and move planets. There's a very good chance it won't be pretty.
Granted, moons aren't "antigrav" forces compared to a star, just a tethered unit to a gravitational mass that includes planet and any mass objects orbiting that planet.
Space time pinches requires solar / star masses to be a factor, planetary masses are negligible compared to a singularity (black hole).
Long story short, if someone can make a solar system do a square dance and I was the leader of an alien civilization; I would make sure that someone couldn't do it again before they mess up the universe too much.

Congratulations. You're not even wrong.
People who are wrong reach incorrect conclusions from an analysis of data. Sometimes the analysis itself was incorrect, or the data was flawed. In a few sad instances, the initial assumptions behind the analysis were wrong to begin with.
You had none of these. You laid down a foundation of flawed assumptions, and then layered on something that we can't call logic. We can't call it anti-logic or non-logic either, because it has zero relation to logic in the first place. There is no path that can be taken, no instructions that can be given to steer a thinking man from proper logic to your method of thought (for lack of a better word, and even then we're using the broadest definition of 'thought' possible).
So, congratulations. You aren't right, but we can't say you're wrong either. We may call you 'entertaining', but only in the way that the Time Cubed guy is.

All I know is The Doctor managed to tow Earth back into position after the Daleks stole it.

I agree this isnt up there with interstellar photonic group collisions producing an interconnecting web of electrons and positrons between stars.

I think that is about as much confirmation as you are going to get ;-).
To dingo:
Are you trying to say that the inverse of [mass of planet]-[mass of moons] = orbital distance?
If so, why is jupiter further out than earth, when it has a higher net mass (the moons of jupiter don't contribute much)? Why is mercury closer to the sun when it has less mass than earth?
Wait... I've been suckered >.<

Blakmane- IIRC, those are legitimate questions that a lot of astrophysicists have been asking for years.
I dunno if they ever got any answers, but last time I bothered to check on it, it amounted to a suspicion that our solar system was not an entirely natural formation (as in, the kind caused by close passes of high-mass objects, not the aliens-did-it kind).
Now, note the above may be off. My knowledge of astrophysics is... not good.

Because Jupiter is a dyson sphere and all its mass is in its shell? Thus there is no gravity pulling toward the jupiter centre pinching spacetime while the mass of the shell pulls the centre apart.
Because Mercury, stripped of its planetary mantle and crust, is slowly moving away from the sun?

You are standing in persistent anticyclonic storm, 22° south of the equator, on the gas giant of a sunless Dyngoson sphere. There is a small delicious cake here.
It is pitch black. You are likely to be eaten by a grue.

The original idea for a Dyson Sphere was a bunch of floating objects in orbit around a sun, gathering up as much solar energy as possible.
Because building a solid shell around it tends not to be a good idea :P

After some research (yes, that means I wikipediaed it), it seems you're missing something, MJ. The idea was not to collect "as much energy as possible", but "all the energy output of the star". Thus, what you could see from outside would be the energy radiating out from the sphere. Due to the sphere, it would be primarily infrared, which was the point of Dyson's original article. That said, it is true that he did not in this article specify what kind of shell might do this. My guess is that it would be a bit difficult to do without making a complete shell. Good idea or not.

His concept is missing a few things... such as how to collect the energy used in plasma jets when the sun feels like emitting something other than light. Until we could build something that could effectively survive being inside the sun, we cannot collect the output that goes into those jets of plasma and cannot harness the total energy out.
Of course, he never focused on the materials involved, just the energy gathered.
