Time and Gravity seems to work in tandem!!!

Are they just one and the same or if they are just connected somehow?

Time is baseless, it all is movement, so we are left with just movement and space, so gravity is a property of space conjoined with movement. Time is but movement given a nickname, besides movement, memorisation of movement is time.

J@i,
That is fine. My question was somewhat rhetorical, in that I cannot see an equivalent way of representing an acceleration due to gravity. You can toy with the acceleration part (ct divided by length per time ^2, ct), but I don't find it possible to ignore the "due to gravity" bit.

To harmonise gravity with time, you need to have some dimensional analysis agreement, as in expressing time as ct as a length.

Hi Cat, I was only referring to your reply #7... If I understand it right, we have three possible known ways that allows Gravity to exist:

1. Spinning Objects simulate gravity effects, this theory should allow us to create artificial gravity in space
2. Einstein theory that massive objects cause a distortion in space-time, which is felt as gravity
3. Theory around existence of Graviton - yet to be proved or rejected

Even if #2 or #3 are proved to be true at some point of time, can we safely assume that #1 will always hold true or will it be otherwise?

Hi J@i, let me put it another way.

Starting from the Force of Gravity, according to NLs,
Force = Mass x Acceleration, therefore I am having difficulty with squaring the Dimensional Analysis. Incorporating Time into the x, y, z length graph (whatever other opinion one might have) is no problem if you multiply by c, since c x t is dimensionally (length / time) x time = length.

To incorporate gravity, we need to introduce mass. This does not fit.

Gravity is felt through matter, certainly matter as we know it, but it is also felt through Dark Matter (DE is not yet understood by me?).

It can today be understood as influencing spacetime fabric as distortion proportional to how that fabric goes near massive and very massive objects. As we expect colliding neutron stars create gravity ripples!

That is an interesting thought. I had always thought of the smaller body orbiting the more massive body and causing the distortion, like a ship creating a bow wave.

Your quote, to me, brings to mind spacetime, like the discredited aether, 'sinking' into a hollow or pit as it approaches a stationary massive object.

Of course, relativity can invert anything, so it is just another way of looking at the question, but it did 'smile at me from the aether' :)

1.
2. (uncountable, physics, historical) Often as aether and more fully as luminiferous aether: a substance once thought to fill all unoccupied space that allowed electromagnetic waves to pass through it and interact with matter, without exerting any resistance to matter or energy
My underlining, not my bold.
Source: Wiktionary.

As a chemist, I prefer aether to ether, to distinguish it from (CH2CH2OH)2O

2.
I did not say "aether". Implied that spacetime could be thought of as a quantum field as we interpret QFT in QED and QCD!
Neither did I. I said

to me, brings to mind
means that "it brings to my mind that" , , , . . . that is purely my subjective thought. It is not implying anything external whatsoever.
