How Gravity Works

[IotaYodi]

Its going to take a lot to convince me that time really exists. Its still an abstract thought that defines a mathematical instant for lwh and cycle or event in a physical world. Without mathematics it would not have existed. As it stands it still exists in the mind but with no real substance to it.
Jmo!

the classic model has four dimensions height width length and time for matter then people wanted to account for energy so lets make it a few more dimensions in the classic model this is incorrect the state of the matter or its degree of being is always relative to its existance first that energy reacts within the model does not alter the third person observere clock which is what einstiens proposal was all about first person perceptions are often scued in some way but the third person clock accounts for all observances and allows clarity of events to occur.
if there was no matter there would still be time as when it occurs those that notice the event would be the marker for it regardless of it continuing to exist it would then only be it happened some ever increasing increment in the past therefore it is given statis for being a demension seperate of physical space.
i hold with these people for there opinion because i have not seen otherwise in my life you cannot make time un accounted for but your well on your way to one of those jobs your talking about as far as gravity goes they know the model is more complicated than originally thought and this does not change the fact that no matter how far something goes or how fast it gets there it will still only be an event on the time marker.

'dimension of time' ??
What is time?....lets think about that......How is time used in the equations?........ what does it 'mean'?

Time is a measurement that denotes a sequence of events. 
FROM the relative perspective of the observer.
How much 'time' does it take after this hapens, for that to occur?
How much 'time' does it take for a mass to move from here to there?
it is only applicable to us, for our purpose of measurement, there is no 'universal time'.
From the perspective of the universe - All Time is One Time.
We are at 'now'  now.
past, present, and future are all the same 'time'.
when we say this thing happened 'before' that, we are simply noting the sequence of events.  It is only applicable to us, for - from a different perspective our definition of 'time' would be meaningless. 
Velocity (from which time is ultimately derrived) is relative.
"how fast" something is moving, can only be compared to the movement of something else.
if you were on a fast moving object, with nothing around to compare it to, you would not know you were moving at all.
how much 'time' would it take for you to travel a distance?
if you travel 10 miles on your object, at 10 miles per hour, then from your perspective you have moved at 10 miles per hour,
traveling 10 miles, one hour of 'time' would have progressed.

from my perspective here on earth, your object is traveling at 120,000 miles per hour.  so in that same hour of 'time; you have moved 120,010 miles.

your hour and my hour are the same. (unless your time keeping device is dependent upon its own relative velocity, such as einstein's theoretical light clock in which case your clock will slow down in comparison to mine.)

if you have an object moving at or near the speed of light, relative to the other objects in a galaxy,
and that galaxy was moving at or near the speed of light in the same direction - relative to some other galactic body....
How Fast is the object within the first galaxy moving, relative to the second galaxy?
The answer is - 2x the speed of light.[as far as what you may or may not 'see' in terms of light emanating off of that object,. i cant answer] but relatively speaking the object would be 2xlightspeed.
Relativity would have you believe this object would run backwards in 'time' and would arrive before it left, but such is not the case.  the 'fastest' that anything can travel from one place to another is instantly. space does not 'curve' with respect to time. Gravity affects light over long distances, the curvature of which is also relative only to us. When we try to examine this with respect to our 'time',- because of the assumption that velocity is a constant,- 'time' becomes variable. Which is an innaccurate assumption, it should be more accurately described as relative, rather than variable - redefined at each incrementation of curvature. If you examine then the light at each part of the curve, from the perspective of what it is curving around - you can see that gravity does not affect 'time', but rather the direction of the light.

@smoky:

Space does 'curve' with respect to time.  It is this curvature of space that allows a moving object to orbit a larger mass.  Study the electromagnet spectrum with the frequency and wavelength being helical in motion as it propagates through space, then you can easily see how space and time are linked together just like the frequency and wavelengths are linked together.

Energy/Mass will follow the path of least resistance.  The path of least resistance is where Time is less.  Time is less where the large mass is located.  Since the mass is curved, then Time is curved around the vicinity of the mass.  Objects will follow this Time curve, which causes the Space the objects travel to be in a curved path.  When you are traveling at C, then your relative energy/mass is extremely high.  Your frequency is extremely high and your wavelength is extremely low.  Since your energy/mass is extremely high, then this causes the space you are propagating through to be curved.  This causes you to travel in a corkscrew motion through space when you have a forward momentum.  This corkscrew motion means it will take longer to travel the same linear distance through space as compared to if you were traveling in a straight line.  When you increase your speed, you are increasing your frequency/energy/mass and shortening your wavelength.  Since you have more energy, your speed will increase, but since your wavelength is shorter, then you will make more turns, which causes you to travel more space within the same linear distance with a higher speed.

Only way to travel faster than C is to increase the Time you are ticking at, or to be massless.  If you're massless, then the thing that is massless won't follow the path of least resistance or Time and won't take a helical path as it propagates through space, but will propagate through space in a straight line.  Mass follows Time, but things that are massless do not follow Time.  Things that are massless is not affected by time, so they can travel faster than C.

I can't believe nobody is catching on.

perhaps because you are omitting the effect of red shift or the dopler effect i think i learned these i high school
even sympithetic vibration has a propogation speed related to time.
curvature of space or not is related to the interaction of energy on bodies having mass without mass it doesn't matter because you won't existbut as a thought and the all bets are off and gravity will not apply at all so you are off topic here.
go read Newton on gravity you will learn something.
time is the duration of physical items the forth dimension.
all you are doing is proving this to be correct for all physical items if you are an esoteric item then all bets are off as then you can walk the underside of a staircase without the use of energy at all i can't do this in the real world.
