That's what I was thinking. "follow the money" comes to mind. They are both counterintuitive, especially when we are taught Newtonian physics first and told when young not to believe in magic.

On the trip "out" the spaceman would "appear"(my "calculated" assessment of how he functions in my "inertialesque" frame based on Earth) to have time very much slowed down for him. The video signal would seem even slower. On the trip "back" the spaceman would "appear"(my "calculated" assessment of how he functions in my "inertialesque" frame based on Earth) to have time very much slowed down for him. (same as trip "out") However, the video signal would seem much faster (look like fast forward)

The idea though is if you could do what losfomot suggests then you could communicate faster than light. If we set up a few (I think you need 3 but with more we could be closer, and at least keep it in our solar system) communications "corridors" with steady streams of these photons then I could tell you tommorrows race results or stock market results.

You cannot assume that. You must allow for the speed of light and the speed of the ship in your reference frame to make conclusions about what is happening in your reference frame.

Who is this big Jupiter guy, and do you think he intends to harm us? Oh wait... the planet Jupiter. Maybe we are safe (for now).

So you might randomly get sucked into the future just because some numbskull from the future trys to get into your present?

Interesting point to what 5614 said: sometimes they pump water upstream (above the hydroelectric dam) during non peak hours in some systems so that it (the energy) is available for peak time use. Obviously there is an energy cost involved in doing this but it allows for a smaller system.

Which is very fortunate for us or the bigger guys might get us! Then again, wasn't the asteroid belt a planet at one time...

Your right, it isn't the case in GR or SR.

Relative to the water/current there is a transfer of power through the anchor, chain etc.

The big bang?

What does wobble have to do with it? The axis orientation is very consistent.

I think if it is approximately spherical it is hyper-spherical with our volume (the one we are in) being the 3D "surface" locally. You cannot point toward "the centre", you can only point along the surface no matter which direction you point in our volume.

People receive patents for stuff that doesn't work all the time. Not saying Herzman's negative friction pneumatic motor falls into that category though.

sorry I edited, I missed the mass part: 1 kg metre/ second squared

1 kilogram(?) metre / second squared
