Unresolved Scientific Questions

Unresolved Scientific Questions
Here is a collection of puzzles for the accepted theories of our day. Many of these queries may appear to be related.
It is up to you if you want to ponder two mor more that you feel are linked
There is no order or significance to their grouping as far as I can see.
Your job is to formulate your own theory. It must be logically correct and have some evidence to back it up.
This is not easy but many people have said you can prove anything with Google. Good Luck
Why is the left eye connected to the right brain in animals with spinal columns? The receptors in the retinas point inward as well.
Really strange wiring if you ask me.
Solar Fusion and the Accretion theory of the formation of the solar system.
 Both are accepted but one suggests that the Sun would have 99%  of the Iron in the solar system in its center where the fusion of Hydrogen into Helium is supposed to take place.Imagine you have an enormous glass and we put all the known chemical elements from Uranium to Hydrogen, you trick is to make the Hydrogen sink to the bottom.
Why is the solar system is extremely flat,? i.e the orbits of most planets lie in the same plane. However, the orbits of Mercury and Pluto deviate from this plane considerably.
How does the placebo effect actually work? Just explain anything associated with dark: Dark Matter, Dark Energy , Dark Flow
Why does the Earth's magnetic field reverse every 700,000 years or so?
brown dwarf
The Cold Dwarf Star problem.
There exists what are called brown dwarf stars whose surface temperatures are the same as those found in your kitchen oven. At ten to fifty times the mass of  Jupiter it seems hard to believe that  they have enough internal pressure to produce fusion.
Look at all the problems we have to create a fusion reactor. Please read the coldest brown dwarf  Some massive planets have surface temperatures of 100° C that are no where near their stars.

Horizon Problem
"OUR universe appears to be unfathomably uniform. Look across space from one edge of the visible universe to the other, and you'll see
that the microwave background radiation filling the cosmos is at the same temperature everywhere. That may not seem surprising until
you consider that the two edges are nearly 28 billion light years apart and our universe is only 14 billion years old."
If we live in a fractal universe then elements repeat at different scales then atoms and stars should resemble each other:
Is gravity analogous to the strong force and thus have no effect outside the Heliosphere? There is some evidence that this is the case

We can image bones and internal organs with MRI what would could cause stars to resonate like atoms in a magnetic field. Could we pick up
their radio signal What would be its wavelength?
to be continued...
While more than 99 percent of the mass of the entire solar system, consisting of the Sun, planets, moons, meteors, asteroids, comets etc. is
contained inside the Sun but it has only 0.5 percent of the angular momentum.
What causes the Earth to undergo extreme cold periods called Snow Ball Earths every billion years or so? Does the tetraneutron really exist? How about a Higgs Boson?.   What would they imply if they do or do not exist?
What causes the Kuiper cliff? Ungodly energetic cosmic rays that seem to come from somewhere inside our galaxy yet there is no known source. Why  is there a clear demarcation between the terrestrial and giant planets.
How come the Sun's rotation axis has a tilt of 6o.  

The Pioneer anomaly   Why are the Pioneer spacecraft accelerating as they leave the solar system? Is this related to flyby anomaly?

Why does pregnancy aid sufferers of the auto immune disease Multiple Sclerosis  (because you have two immune systems working) but not those of Lupus?
What was the Wow signal and what are the implications? Hey what made the Bloop?
What is the difference between Pellagra and Lupus?

Are Universal constants really that reliable?
Could we be destroyed by a killer dust cloud from outer space?  What really would happen if our planet ran into a interstellar dust cloud?
How could dinosaurs with wingspans as large as a jet fighter fly? How much did they way? Anti gravity anyone? 
Looking Back at Uranus
false color uranus
There are at least two mysteries that concern the 8th planet.
1. Why does Uranus have four magnetic poles? Not only that but the strength of the field varies wildly from much weaker than Earth's to 4 times it.
2. Why do the two horizontal poles have the same temperature even when only one faces the Sun.
saturn's hexagon
Why does Saturn have a hexagon?
 Is the planet French?
Why are American's fat?
In the 1980s the explanation was genetic but from 1986 to 2009 American obesity became an epidemic. CDC obesity Map
So why. Current theories suggest it is too much food and little exercise yet... Bill Bryson's book the Thunderbolt Kid states that in 1953 American's were eating 50% more than their European counterparts and were using their cars to go everywhere?
