Equation, is this correct and if it is could u help me out??

[Ethernos D Grace]

Density proportional to curve in space time.
I.e. D=k x l
Mass/volume = l x K
Energy/volumex c^2= l x k
E= V x c^2 x l x k...... Eq1
Gravity proportional to curve in space time
I.e. G=p x l
l=G/p...eq2
From eq1 n eq2 we get,
E=(G/p)x k x V x c^2
From what we can see here if the energy were to be quantized we can also quantize gravity. Hence quantum gravity.

Not much meaning unless you tell us what the variables are.

Energy does come in quantized form: photons.
Gravity is not "proportional" to space time; gravity is the physical manifestation of curved space time.

Why do you think density is proportional to curved space time?

E=L x K x v x c^2
Here, E = energy
K = constant

Why do you think density is proportional to curved space time?

Because of black hole i guess.

MASS PROPORTIONAL TO BEND IN SPACE TIME.
THEN
E= K x L x C^2
L = curve in spacetime
K= proportionality constant between mass and spacetime curve
K x L= mass
L= E / K x C^2..eq1
Nw quantizing eq1 will give curve in space by a photon, i guess.

So does this mean you don't think that density is proportional to curved space time anymore?

MASS PROPORTIONAL TO BEND IN SPACE TIME.

So, here on Earth I mass 84kg. If I were to take a spaceship out to where space time is much flatter than here, I would mass less? Could I find a place where I have a mass of zero? Cuz that would be cool, since I would immediately accelerate to the speed of light.

Ethernos, please stop. This is complete nonsense, and not what this forum is for. If you have free thoughts about stuff, please post it in the Free Thoughts forum.

So, here on Earth I mass 84kg.

No. Here on Earth you weigh 84kg (fatty!). Weight depends on the gravitational field, mass is a scalar invariant.

If I were to take a spaceship out to where space time is much flatter than here, I would mass less?

Yes, you would weigh less, your mass would remain the same

Could I find a place where I have a mass of zero?

Yes, sufficiently far from a gravitational source your weight approaches zero, your mass remains the same.
Ever hear of astronaut's weight-less space-walks?

I think that is Dave's point - about the absurdity of what Ethernos is saying.

 

[DaveC426913]

No. Here on Earth you weigh 84kg

No. On Earth, I mass 84kg - like I mass 84kg everywhere else.

Ethernos seems to think that mass - not weight - is affected by spacetime curvature. As if, once out in flat space, I would mass nothing.

The opening post and everything else in this thread from Ethernos is cranky, and looks a lot like trolling. But just in case it isn't...

Ethernos:

MASS PROPORTIONAL TO BEND IN SPACE TIME.
THEN
E= K x L x C^2
L = curve in spacetime

Please explain how you are defining "spacetime" and "spacetime curve" mathematically in your analysis, and what the value of "L" represents and how, specifically, you calculate that from a particular configuration of spacetime.

Please provide at least one example of such a calculation of L from a spacetime of your choice. Do not use words like "I guess" or describe how you might do it. I just want to be able to follow the precise definitions you are using. Also, is this your own work, or are you drawing on other sources that you can refer me to?

K= proportionality constant between mass and spacetime curve
K x L= mass

What are the dimensions/units of "K"? And why is "spacetime curve" proportional to mass?

Please explain. You may link to relevant references if necessary, but probably a brief explanation will do.

L= E / K x C^2..eq1

Just a hint: if you're using "x" to indicate multiplication it is unnecessary and potentially confusing. It is probably better to leave it out. Also, your equation is ambiguous, because there's no simple way to tell whether you mean $L = E/ (Kc^2)$ or $L=(E/K)c^2$.

What is "E", by the way? Is it energy? What kind of energy? Energy of what?

Nw quantizing eq1 will give curve in space by a photon, i guess.

You guess?

I thought you already had a working definition of "spacetime curve".

Can you give me any example of how you quantise an equation such as the one you have posted? It doesn't have to be this specific one. I just want to see that you understand how things are quantised.

Also, previously you talked just about "mass", but all of a sudden you got more specific and started talking about photons. How did you go from the general to the specific?
