Not what I called for, Funkaloyd. I want the exact same analogy on earth using vacuum/nonvacuum.

As I think about it, it would seem that the dropper looking back would view a slower velocity of drop, than if the train were stopped when he viewed a drop from a standstill and that if the bystander and the moving (moving edited in) dropper both had stop watches, the time would be equal from drop to contact.

This is not an "analogy". It is a a thought experiment. It is an example of a certain situation, for which we can perform calculations to determine the results, and then check if our calculations actually match up with the real world. The reason for having a vacuum is technical, but it does not actually make a significant difference. The time dilation effect mentioned in my previous post turns out to be an aspect of the same phenomenon. The speed of light is the same for all observers. It makes no difference how fast the source of the light is going, or how fast an observer is moving. If you move towards a photon source, you still them coming at you at the same speed as if you are moving away from the photon source. Weird! Illogical! Fact of life confirmed by many experiments and observations! Is the reason you can't use the train/vacuum train/non vacuum thought experiment is because it won't make your point. You will get different velocities as stated in the experiment both ways? Like if you're flying in an airliner, you see an eagle flying in the opposite direction of your plane out the window. It appears he's flying at his normal speed/velocity plus the speed your plane is going. But if you could expand the size of your cabin and the eagle flew past you within your aircraft, he would be moving at his normal speed only. Is this relativity of the eagle within or without the cabin in any way analogous to your experiment? Also a fly flying in the direction your jet is moving can fly at jet speed plus his own speed inside your aircraft, but outside your aircraft, it's by by flying fly. I don't know. I'm still trying to think it through. It appears to have to do with relativity. I don't give much credence to analogous stuff/experiments which are dissimilar to the extent that yours is. It is after all, analogous. I haven't got my finger on it, but something seems to be skewing the experiments to your advantage. I'm hittin hay and will likely think myself to sleep on this fascinating stuff. The immeasurable present is forever consuming the eternal future and extending the infinite past. buzsaw

Thanks Sidelined. You've got me thinking. Something logical's gotta come out in the 'wash' in the end though. Imo, none of this in any way expands or curves space. It's still all about stuff in space we're dealing with. Talk to you people later, Lord willing. Off to church tomorrow. Take care and go with God, Jehovah, that is.

Hi Trae.
Does it take energy for nothing to expand? Since you seem to have a handle on it, what exactly is energy. I've been trying to get a better grasp on the concept. My "handle" is logical and scientific, as per thermodynamic laws and it will be limited solely as pertaining to the topic of space so as not to be off topic. Concerning the "fabric" or properties of space, neither I nor, imo, my counterparts have yet offered any properties capable of being energetic, nor of the capability of expansion. Space is static and unbounded, existing area in which energy and matter exist. The immeasurable present is forever consuming the eternal future and extending the infinite past. buzsaw

My point will be made whether you are in a vacuum or not. Why then did you use a vacuum model for the space visual? I was puzzled about that and trying to figure the significance of it as I thought on this. I am assuming that the space shooter is also in space in the area of the spaceship. Is that correct?

V-Bird writes: Your post in my opinion is very accurate indeed, if you were to conjure any 'fabric' to space then it is energy [as EMR] the 'space between the stars [which are themselves energy in 'solid' form] is full of EMR. When you hear or read that space is 'bent' around a gravitational body such as a star so the light 'curves' in space, what they actually mean is that one form of energy [gravity] has acted upon another form of energy [light].We often forget to include this fact when talking to those interested in learning more about Relativity and the result is the shocking idea is formed in many minds that there is some 'other' substance out there called 'space', there isn't, there is energy and it is constantly being swayed by other energy that forces into performing the things we see like light bending around a large star. As I understand your statement you are alleging that the only property of space is energy as electromagnetic waves. Question: Where does this energy, i.e. electromagnetism exist?

V-Bird writes: the areas we see as 'empty' space is full of another aspect of energy conveying what all those other aspects of energy are doing. Oh. Fine. Okay, we agree on that much. Energy exists in space. The unresolved problem, now, is that you can't have it both ways. Either all forces, energy and matter exist in space, or space is energy. Which is it?
