Space Density Compression Ratio

Consider a space density function of the form,

ds(x)=Aebx+B  where A, B and b are constant to be determined.

At  ds(0)=de space is compressed, its space density is ds, on surface of earth. And ds(x)=dn where at long distance, space is relaxed and the corresponding space density is dn.

We have,

ds(x)=ebx(dedn)+dn

Then we let the inverse relationship between time speed squared v2tand space density, ds(x) to be,

v2t=CDds(x) where C,D are to be determined.

We know that as x,ds(x)dnwhere space is relaxed and time speed is c,

v2t=c2, ds(x)=dn

C=c2+Ddn then,

v2t=c2D(ds(x)dn)

If we then consider the time dilation equation from previously, (The use of this equation is still valid because a linear approach can be consider as a first approximate to an exponential one.  Consider the power series expansion of e.)

vt=c22Go(x+re)

when x=0

v2t=c22Go(re)

 v2t=c2D(dedn) where ds(0)=de

we have,

2Go(re)=D(dedn)

therefore,

D=2Gore(dedn)

Hence,

v2t=c22Go(ds(x)dn)re(dedn)

So,

γ(x)2=12Go(ds(x)dn)c2re(dedn)

Comparing this with the equation obtained from gravity,

γ(x)2=12Goc2reegoreGo(x)

egoreGo(x)=(ds(x)dn)(dedn)

But, ds(x)=ebx(dedn)+dn

egoreGo=eb

So, b=goreGo=1re

because go=Gor2e

We have for the case of earth,

ds(x)=e1rex(dedn)+dn

Similarly, for black hole

 dsB(x)=e1reox(dBdn)+dn

Differentiating both expressions

d(ds(x))dx=1ree1rex(dedn)

d(dsB(x))dx=1reoe1reox(dBdn)

Since both are proportional to gravity,

ge(x)gB(x)=reoree1rex(dedn)e1reox(dBdn)

and so,

dBdndedn=gB(x)ge(x)reoree(1reo1re)x

when x = 0,

dBdndedn=gB(0)ge(0)reore.1

Therefore, the relative amount of space compression around a black hole is,

dBdndedn = (5.07071e18/9.80665)*(0.00886/6371000) = 7.191e8
