You are doing the same thing once again. You are giving some simple Cartesian math describing the topology of 4-spheres in relation to a tesseract without describing how this relates to your statement that extra dimensions would need to be be macroscopic.
I guess I shouldn't have bothered posting about this on codeproject. 
I should have posted a Haiku instead. 
Need to get some work done today so can't continue on this topic. I'd like to hear more from you if you can assemble something I can understand. You can sometimes find me (in the evenings) in the intellectual dark web on discord and also the Wolfram channel. I am also in the C++ channel on discord.
Best Wishes,

What happens when galaxies collide? If the atoms are already packed at the maximum density, wouldn't this create a real big boom? Or maybe they should bounce off each other? 
|
|
|
|

When they collide I can envision a lot of options:
- They're mostly empty space and can pass through one another (with gravitational distortions)
- The combined gravitation from both galaxies will cause them to combine into a new galaxy with a new density
Were they composed of charged "star" particles than they could bounce off one another in a manner similar to that in which we give material objects the property of "solid" when in fact they're mostly empty space.

Well, they act like big clumps of smaller items: Antennae Galaxies - Wikipedia[^]
And several dwarf galaxies (such as the Sagittarius Dwarf Spheroidal Galaxy) are currently colliding with the Milky Way and merging with it.
I think that means that the galaxy can only be considered as a single object in aggregate - on a finer scale it's clearly an assemblage of smaller independent objects held together with a "glue" we call gravity, but which seems to be a distortion of "flat" spacetime.
But I'm no astronomer, no large object physicist: it just seems to me that somebody is trying to ignore fine scale objects to make calculations easier (in the same way that ignoring electrons, protons, and neutrons in favour of indivisible atoms does on a smaller scale).

Lots of alternative theories. Black holes can provide the mass, as well as stars that are made up of nothing but bosons.

"Simple"?
My chilli is, yes. Anything involving gravity isn't, usually.

Which higher dimensional space? It that theory, math, or something one can prove?

To my knowledge nobody has been able to design an experiment for determining if higher dimensional space exists. The closest thing we've got is the recent discoveries by Dan Shechtman[^] where aperiodic crystals found in nature hint at a possible projection from higher dimensional space.

OK - today I do that deed (having been fully "prepped") by submitting myself to the whims of a gastroenterologist. I need some advice due to the following observations:
He wears a pith helmet[^] during procedures
There were the heads of several gerbils stuffed and mounted on his wall
I have the feeling he sees his job as gerbil-hunting and am afraid what will happen if he's disappointed.
Special Note to Chris M: I just thought up an enhancement for the "Type" category for here, in the Lounge. The "Too Much Information" selection, along with an appropriate icon of warning.

Bring a samurai sword and insist on remaining awake during the procedure.

you actually can stay awake for the procedure. However you will then feel most of the procedure. Depends upon your comfort level with said procedures process. Which would explain the gerbil heads on the walls. HAHAHAHA.
Be prepared to toot your horn for a few days with all the extra air they use to expand the region so they have a better excursion.

I remember, in the recovery room six years ago, producing such a blast as to have easily taken down the Walls of Jericho. Strangely odorless. And then it was done.
Many years ago I experienced this without anesthetic. There's an expression used when one has eaten a lot whereby they exclaim "I could bust". That feeling can be real. A definite once-is-too-many experience.
Before long I'll know my weight sans any digestive content. This allows two interesting observations:
- I can actually time the duration of digestion for that first meal afterwards
- At any given moment I can weigh myself and know precisely "Just How Full of It" I am.

They use air to inflate the bowels so they can see more. You're "prepped", so your intestines nearly empty, not much there that can generate smells.
W∴ Balboos, GHB wrote: Many years ago I experienced this without anesthetic
Ditto. They also extracted 12 small pieces to test, by grabbing the instestines with a hook and simply pulling that part out.
Nowadays, before the procedure begins, I get a sedative, a painkiller, a sleep-aid and get strapped to the bed. Legs and hands.
As for the prep; it used to be a small sip of magnesium done easily, and it changed to 2 liters of salt water. The price difference is small, but on a large amount it adds up.
Hope that the results are at least good.

They took three trophies for analysis. Probably a week before I know.

Magnesium sulfite, IIRC; not a metal, but a "salt". Is not a salt in my kitchen.

If something serious, you be told within a day. I'm "checked" every year. Just glad I'm a developer, not an arse-looking doctor. Imagine doing eight of those each day.

He *found* one? Meaning you didn't even notice if there? They can get rid of those easily, although you do a Monthy Python walk for a day.
Have something good to eat.

Well, you said drink magnesium and, since it's a metal, I presumed they melted it so it could be quaffed. MgSO4, commonly called Epsom Salts, is quite different. Eddy Vluggen wrote: Just glad I'm a developer, not an arse-looking doctor. Imagine doing eight of those each day.
In order to relieve the work pressure (a pun?) these guys often have another office next door where they practice dentistry. There is a certain danger if they get confused.Eddy Vluggen wrote: Meaning you didn't even notice if there?
Internal (sneaky little critter). Current recommended treatment: leave it alone.
And all readers will be thankful to know that no gerbils or ferrets were injured during the procedure.

They didn't call it Epsom salt, but magnesium-something. Tasted like lemons, but only required one swallow. Compare that to some liters of seawater.

Dentists; I often joked at both practices how the denstist digs in more bacteria and has a dirtier job than the one doing hemmoroids.

Gerbils can't survive in a colon, despite the claims on Google. They'd suffocate while biting a way out. Both Gerbil and host would be dead in minutes.

Epsom Salts = Magnesium Sulfate.
My "stuff" was about 70% Sodium Sulfate and 15% each of Potassium Sulfate and Magnesium Sulfate.
Being an ingredients reader since I learned to read, I looked at the other contents - which included a lemon flavoring and sweetener. I suppose it was more palatable. Just not possible to drink it quickly enough as it seems to fill the mouth, throat, and all, very quickly. Anyway, your stuff tasted like lemon because the lemon'ed it for you.
There really important thing about dentists and proctologists is to never mix up their office locations when in need of their services.
You are mistaken as the gerbils in question were hatched in-situ.

Better than two liters of salt water.

There's more bacteria in your mouth than on the other end.

..hatching happens from eggs, gerbils are mammals. In situ, so there was already a colony there?
