Which is of course one of the signs of crackpot conspiracy theories.
The reason you can't prove it is because the conspiracy is hiding the
evidence!

The scientific process isn't as pure as perhaps it should be. It is
after all a construct of humans and subject to its share of prejudice,
self interest and outright fraud. Still the truth will come out and in
much less time than through any other system going around.
The examples of initially rejected theories that are eventually accepted
are out there. Actually they are good illustrations that the system
works. Radical theories need strong evidence and should be subjected to
assault by those who defend the accepted theories. Don't expect to
overturn the whole world of physics (or biology, or cosmology etc) in an
afternoon.
Jumping to use those examples to support a new theory or ideology is a
sign that it is weak in itself.

It is so transparent as to be ludicrous. As compared to real science it
is laughable. Of course those who jump on board want to have it seen as
an equal 'theory'.

That is an insight that makes sense to us.
Unfortunately once you believe in an omnipresent, all knowing, all
powerful, arbitrary and apparently uncaring but malicious deity then
anything is possible.

Quod enim mavult homo verum esse, id potius credit. For what a man would
like to be true, that he more readily believes.

Thanks for that.
I never was good with irony.

I don't think it would be physically possible for any kind of life to
form that far from the Sun.
Chemicals need to react with each other, which means that there must be
some kind of solution where they can freely float or otherwise move.
This usually means some kind of liquid. Obviously some kind of energy is
also needed or else nothing will move.
Water would be the liquid of choice because it has two very special
properties that basically no other liquid has: It's extremely common,
and its solid form has lessed density than its liquid form. Without these
two properties there would be no life on Earth (or anywhere else). (There
are probably also many other necessary properties, related to solubility
and how water reacts chemically with other compounds, but I do not know
enough about chemistry to say anything about that.)
It's hard to imagine how life could form without water.
Of course for the water to be any good, it has to be in liquid form.
If you are too far away from the Sun, all the water will be frozen solid.
This isn't a very fertile ground for life to form. There are little chemical
reactions going on, chemicals are not very free to move, and there are
probably a huge bunch of other properties necessary for *any* kind of
life to form which just aren't possible with deep-frozen ice.
Now, perhaps if there was a liquid which remains an liquid form at those
temperatures, it could ostensibly happen. However, such liquids are both
extremely rare (iow. there wouldn't be enough of it in any given planet),
and their chemical properties are probably inadequate for any kind of
lifeforms. (Also, most liquids other than water get denser when they
solidify, which is a big problem.)
(Conversely, a planet which is too *close* to the Sun cannot form life
either, this time because there's no water because it's all vaporized away.
It also makes forming a viable atmosphere quite hard, making it a very
hostile environment, where strong radiation hits directly the surface
of the planet, destroying any complex chemicals that might form by chance.)

I wasn't really disagreeing. Just pointing out where the hypothesis came
from that the evidence turned into a theory.

FWIW, that's not at all what reversible computing is about. Reversible
computing is a necessary prelude to quantum computing.

I sometimes argue that perhaps the universe is not logically consistent, in
exactly this sense, and I usually get shouted down. Maybe there isn't any
mathematical way to describe everything in the universe, and depending on
what you measure, you will *always* have errors due to the fundamental
nature of the universe.
Granted, I often raise this in the context of "scientists have faith that
this isn't the case", in the sense that it would be very unlikely a smart
scientist would give up looking, ever, for that elusive theory that applies
everywhere.
