Space-Time Curvature In N-Dimensions

[SaxonViolence]

Gravity is a curvature of Space-Time...Yes?

 

I've seen all sorts of beautiful diagrams showing this.

 

{But if it turns out that there actually are "Gravity Particles" then the complications boggle the mind...}

 

Take as many hypothetical higher dimensions as you need.

 

Is there any conceivable way to bend Space-Time in such a convoluted way that "Down" can be towards the inner surface of a huge hollow sphere?

 

I know that you could spin the Sphere, but that only gives full gravity along a narrow slice.

 

Any way to get uniform gravity inside the Sphere?

 

{In theory. If I thought I was onto a workable Artificial Gravity/ Anti-Gravity, I'd be wasting time writing this...}

Gravity is the presence of curvature yes. It is also the presence of acceleration and matter-energy. ''Some'' think it has something unique to do with time since space and time are unified under the theory of relativity.

 

''Is there any conceivable way to bend Space-Time in such a convoluted way that "Down" can be towards the inner surface of a huge hollow sphere?''

 

Conceivable yes, but not practical. You need huge amounts of energy to reach what is known as the Planck Energy. As for uniform gravity, in what sense?

You also, don't need to invoke extra dimensions to understand gravity.

Regular Gravity doesn't require extra dimensions,but If you were trying to do something really fancy...

 

Phillip Jose Farmer used the idea of "Miniature Created Universes" in a series—but his were all the size of our solar system, if I remember corectly.

 

I was contemplating the idea of a story where the Hero has figured out how to create much smaller "Extra-Dimensional Universes"...

 

Spherical and between a couple square miles—to perhaps the interior surface area of Alaska at the very largest...

 

And assuming that you can somehow "Blow Bubbles" into a synthetic N-Dimesional Hyper-Space—Is there any semi-plausible way to give them a surface gravity like miniature Pelucidars?

 

I mean, imagine a neighborhood where every house has an interior door into its own 1300 Acre "Back Yard"...

 

Also, I was playing with the idea that the inventor refuses to reveal how his process works. There is no way to detect the mini-universes. People are claiming that the Government has no Jurisdiction in the mini-worlds...

 

And so on.

 

I suppose that they could just be spinning cylinders, but I like the idea of a 1300 acre spherical park—walk about a quarter mile or so in any direction and you're back where you started.
