As to what particles make up space and time, good luck with that one, news at 11. Strings, triangles, lots of hypotheses but no evidence yet.[/b]
That's pretty much my question though.
Essentially all we have is observation regarding how celestial bodies react to each other. Everything else appears to be a mystery and controlled by forces we don't really understand at all.

Saying curvature of space-time causes gravity is like saying low pressure areas are caused by curvature of the atmosphere. Do clouds move toward low pressure because of a curvature of the atmosphere?
No it doesn't. I don't know where you got this notion that gravity is due to time dilation, but I strongly suggest you try another reference.

Time dilation causes curvature of space-time.
WOW your combination of ignorance and arrogance simply knows no bounds. So you think you understated relativity? -your above nonsense assertion proves you certainly don't at it is complete and utter gibberish to anyone with a physics degree.
Please show all us scientists that we are all wrong just simply by showing us ANY real science link that says or clearly implies “Time dilation causes curvature of space-time” .....
-failure to do this only confirms what we already know.

Curvature of space-time can be viewed as being gravity as opposed to 'causing' gravity.

note that the examples of "time dilation not causing gravity" I speak of here are examples where there is time dilation without gravity being present or at least without greater gravity being present.

"Curvature of space-time can be viewed as being gravity as opposed to 'causing' gravity."
Time dilation is gravity. Curvature of space-time is just a term to visualize the effects of gravity much like there are curvy lines around low and high pressure areas on a weather map.
I never said curvature of space-time causes anything. Personally, I don't like the term "curvature" when describing space-time. I accept the term only for lack of a better one. I do agree with your statement above, but that still leaves gravity a mystery unless you accept that gravity is time dilation.

Curvature of space-time does not really happen if you use the term curvature literally. I could argue there is no such thing.
You could say that curvature of space-time is the same thing as gravity. You could say that both are the same as gravitational time dilation. I think you are making the mistake of thinking gravity has an explanation at all. Anything we explain it with also lacks explanation. Can you explain what causes gravitational time dilation? Can you explain what causes curvature of space-time? Don't say gravity. They are the same thing, right?

I am aware of time dilation without gravity, but that is from moving through space. That does not disprove gravity is time dilation. The two could also be linked. All atoms have electrons that travel close to the speed of light in the confinement of their shells.
I guess you could say I am just renaming gravity, but I am being more specific so I don't see it that way.

It's hard to disprove anything about gravity because you cannot measure it other then observing invisible forces moving things like in a cheap horror film in October.

Why don't you try publishing your idea that time dilation causes gravity?

How would you know this? What is the source of your information?
You don't even understand any of it.

Why?

How would you know when you don't understand anything about it?
Can you explain what causes gravitational time dilation?
There are people far smarter than you are that can but you would have insufficient intelligence to understand any of it.
