Default planetary heat losses

All the outer planets radiate much more heat than they receive in
energy from the sun. All that is except Uranus which radiates
negligable energy not received from the sun. Theories try to explain
this but nothing so far has been put forward that can be proven or
for
that matter even sounds plausible. This is a major problem in
explaining the formation of the planets, along with the current
opinion that Uranus and Neptune could not have been formed out of
primordial material at their current distances. But what if the
explanation is much more simple? Consider 8 iron balls taken out of
an
oven in your kitchen. They will cool at a rate consistent with their
mass and material. Those with similiar mass and material will be at
about the same temperature at the same time , say, a couple hours
from
now. Jupiter Saturn and Neptune all radiate between 2 and 2-1/2 times
the energy they receive. Why is one planet, Uranus, so different?
Lots
of people have tried to explain this with sophisticated ideas like
helium rain, or metallic hydrogen, or a solid diamond planet core and
even the collision of an earth sized "dwarf-ice-planet" with Neptune.
But what if the answer is much simpler? What if Uranus is colder
because its much older than the other planets? Remember the iron
balls
from the kitchen, or if you prefer, fresh baked cookies from the
oven?
And then, lets say, you came across one cookie that was cold? Lets
say
then that your grandmother looked at you and pointed out that
obviously it MUST have been made earlier? She may have even chided
you
about not having seen it before, on your own? We have planets in the
much belabored "ecliptic" however these angles are not precise and
have not been adequately explained when compared with the asteroid
belt versus the spherical nature of the Ort Cloud and the wild angles
of observed objects in the Kuiper Belt. There is room for influences
here not yet understood.

What if?

Venus is getting rid of roughly 20.5 w/m2, and that's roughly 256 fold
greater than the core heat loss of Earth. Therefore, Venus is a
relatively newish planet, whereas Mars is likely older than Earth, and
our salty old moon is simply not even made of Earth.

Not all planets or moons are those of our initial solar system,
whereas interstellar migrations have taken place. As you say "There
is room for influences here not yet understood", but we do have
sufficient supercomputers and of their 3D fully interactive orbital
simulators that'll prove out most any theory. Too bad such nifty
applied technology and those our best talents are not being allowed
anywhere near such supercomputers (most of which being public
funded).
