Dear Marco,

The idea that the universe has a hyperspherical shape is an idea that I like and use, since it solves the problems of its limits very easily.

Besides, I think I have been able to prove it, since I have deduced Einstein's field equations only based on that hyperspherical form.

Remember also that several thousand years ago the Earth was also considered flat..

Dear Sergio,

By the way, what you call a hypersphere is different from what I call a hypersphere. I call our Universe's 3D spatial coordinates to be the locus of a lightspeed expanding hyperspherical hypersurface. Time is there to time the expansion and it is not part of the topology, as it is in a 4D Spacetime.

That also means that the forces we know are perpendicular to the direction of motion and cannot influence expansion. Hence, you CANNOT derive Einstein's equation from the topology that is consistent with SDSS astronomical observations.

If you use it and used it only after 2006, please refer to my work as a precedent to your usage. You can get my timeline from here:

I say that, not just to be protective of my own work, but also to ask you for your understanding since I have being censored since 2005.

Using it as an "idea" is different from using it as the result of astronomical evidence. I provided that evidence by analysing correctly the Sloan Digital Sky Survey.

If you learned about the Universe being a hypersphere, you should also had learned that it travels radially at the speed of light. Most academicians don't thread there, and by doing so, that refutes General Relativity, L-CDM etc.

I provided falsification of all Dark Matter and Dark Energy. That is what I was referring to when I mentioned my correction to Newtonian Dynamics.

So, I was suggesting,

You cannot model the influence of the deterministic recurrences of the hyperspherical mode if you don't use the information we already have about it.

If you want to replicate my discovery, you can do so,

https://hypergeometricaluniverse.quora.com/Universe-Trove

the scripts are in a github repository:

https://github.com/ny2292000/TheHypergeometricalUniverse

I strongly suggest you to do so, since the emotion of your first time seeing the Universe is overwhelming...:)

If you have trouble with the scripts, let me know.

Dear Marco,

There is only one definition of a hypersphere and embedding in a 4-dimensional Euclidean space must comply with the following relationships, if it is not, it be something else, but not a hypersphere:

http://mathworld.wolfram.com/Hypersphere.html

On its surface if you move in "straight" line in any of its 3 intrinsic dimensions in the end you will reach the same point, but from an extrinsic point of view, Euclidean of 4 dimensions you will see that its geodesic lines form circles

Yes, that was my first idea, using time as the hyper-radio dimension, but there is a problem, what happens if we go backwards in time? there is a time 0, and before? What existed before time? How was time created? with the energy? Tell me some energy process that can create time? it is evident that time can not be that 4 dimension because it gives many problems..

Yes, you can get Einstein's equations (look at my work and check it yourself ...) based on a very simple idea, if the universe is hyper-spheric and contains all the mass-energy of the universe, that mass-energy is what gives it its shape (obviously, less mass-energy will cause less curvature) (look at the part where I explain gravity, you'll see that it's so intuitive that it almost comes out alone), and showing before that E = mc^2 is a potential energy, knowing the how and why of that energy and doing a series of calculations

" If you learned about the Universe being a hypersphere, you should also had learned that it travels radially at the speed of light. Most academicians don't thread there, and by doing so, that refutes General Relativity, L-CDM etc. "

Yes and no, look at my way of deducting E = mc ^ 2 and the medium I use for the transmission of light to understand it better..

" If you learned about the Universe being a hypersphere, you should also had learned that it travels radially at the speed of light.

1. you not using L-CDM, Dark Matter in your modeling of galaxy formation"

I do not treat dark matter in my work, although it can easily be seen that if the universe is hyperspherical and the light propagates Euclidly in a straight line, to the distant galaxies mass-energy should be added to obtain its real curvature (although that does not mean that that mass-energy exists, it can be an error of "perception")

" 3. using the Hypergeometrical Force and Loaded Matter to explain galaxy formation instead. "

I think, more or less we refer to the same, but I interpret it as the force that creates the matter (see my deduction of E = mc ^ 2 and you will understand ..)

And now that I think about it, if you use a signature - +++ or + ---, you can not use a hypersphere directly like I did, should you make the corresponding change to adapt the hypersphere to that metric, no?
