pm me if you ever have any question.

... which makes everyone happier.

So since any part of the universe could be considered "local" by it's inhabitants, none of the Universe is expanding? More like: The Laws of Physics are valid anywhere in the Universe, and the only "point" with "zero expansion" is a single point. The space between any two points is increasing, and the rate of expansion increases as the distance between the two points increases. So the "Space" between the Earth and the sun is in fact expanding. Or: You don't know shit. The universe does not have many inhabitants, or matter, or anything else but space. So, yes for the inhabitants, their local space is not expanding, but it is the distance between these local spaces that is increasing. To make your argument true, matter would also need to expand. Since the space just above earth would also be expanding, which would cause an increase in circumference just above earth, but the earth itself is not increasing (unless mater expands as well). Somewhere in there the expansion of space has to take into account matter, which what is considered 'local'. If I remember right, physicist consider 'local' to be the milky way galaxy, not just the solar system. I also know shit, he is a good friend of mine. Matter is, indeed, expanding. Or rather, the space between each teeny tiny particle is growing b/c each is moving away from the other. This is not true. If the amount of space was increasing between particles the wave lengths given off by particles changing quantum levels would be changing also. This has not been observed and doesn't fit any theory. It also conflicting because more and more energy would be needed to expand the distances fo each level when in fact, the universe is experinecing enthropy. Clusteres of matter are increasing distance from each other in space. We can observe this by using the doppler affect. Each cluster is generally a galaxy. Just think of an explosion and each galaxy is a chunk of debris. As far as every particle, thats just not true.

Phew!

Your graph explanations doesn't make sense to me. Do you mean the distance from the center of the Earth onthe Y axis vs time? In this case, if y is contant over time (ie a straight line), then in that coordinate system, dy/dt =0 and d^2y/dt^2 =0. If you were to plot a parmetric 3D position graph with stationary coordinates, yes, we would be moving in orbit around the center and would be accelerating (ie. you would see a circle of our position). However, if the graph rotated with the rotation of the Earth, there would just be a dot of our postion.

You would be accelerating with respect to the Earth if you jumped in a hole, because you would have no Normal force opposing the force of the Earth to keep you still, as we do now when we sit here. If you want to incude rotation into this, then yes, we are acclerating. The Earth rotating gives us centripetal acceration of about 0.0339 m/s^2, not 9.8. If the coordinates are not rotating, then yes we are moving (and accelerating) relative to those coordinates. However, if you base your coordinates on the rotating Earth, our position is constant in that frame.

and: but Einstein said: "we [...] assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system." Did you go to WWU? You should demand a refund!! I need no refund. Einstein was correct. "Whenever an observer detects the local presence of a force that acts on all objects in direct proportion to the inertial mass of each object, that observer is in an accelerated frame of reference. " We feel the force of the Earth, therefore we are an observer in an accelerated frame of reference. However, that does not mean that we are accelerating relative to the Earth. It is different. Einstein does not defy math. If our position is x(t)=0, then x'(t)=0 and x''(t)=0. We are in an accelerated reference frame, that's why we feel gravity, however, the normal force of the ground is keeping us from moving. Therfore x''(t)=0 relative to the Earth.

My mother used to live on a farm in North Dakota when she was a child. To keep the ducks together, they would make a duck swallow a piece of string and it would come out their butt, then they would make the next duck swallow the string, etc....until they had a sting chain of ducks. Hence, string theory

I like quarky books, especially about quarks. No I meant quacky. Maybe that word was genetically inheritated

You just read Big Bang from the dude who wrote The Code Book, didn't you? I have a degree in Physics, one in Math and I am a member of the American Astronomical Society. I don't read those quacky books other than for pure entertainment.

If you make a redshift map of the known universe, you can quickly tell that we are part of the spreading debris of an explosion, not at the source position of the debris. It is impossible for each person to be the at the universeal "redshift null" at the same time, since the source is a singular point in space.

We each are the center of OUR universe, not THE universe.

ala carte ?

However if the Earth is the center of the Universe (barf), you may not be accelerating.

You are accelerating now in space. Velocity = speed and direction. Your direction is changing constantly though space. However, you are still on Earth while you spray, so relative to the Earth, you're not accelerating. This thread is going to drift to spacetime metrics and light cones....I just know it!

I'm numb to the stench now. Just something that comes with the territory. Chalk over everything and stinky shoes. You can't fight it forever.

Gravitational potential energy is doing all of that work. no work = no calories burned = fatass!

They can show bush on TV now?

That sounds really good! I may have to switch from my normal salad for a day. But I'm also to considering the Indian Buffet. The Chicken Tikka Masala with Naan is MMMMMMMMMMmmmm at Maharasha(sp?) where is this at?? Yumm Indian Buffets are good....There's a place in Bellevue that does DINNER Buffets..YUMM!! I ended up going to Indian for lunch. It was gooood. This one is in Bellingham. The dinners are better than the buffets. The Chicken Tikka Masala with Naan is all I crave.
