Default The sun is a nuclear reactor converting matter into energy



The sun is a safe enough distance away so that its harmful radiation is
filtered by our atmosphere.

Earth's center is far enough away that the harmful radiation from its
converting matter into energy there is filtered by several thousand
miles of matter.

For years, I've been advocating that as Earth gets bigger and hotter it
wil eventually become too hot and radioactive for human habitate. It's
therefore imperative to the human species that we do all we can to look
for alternative locations to establish living quarters, if we want to
maintain the human and other life species.

Hench we must think of the moon, mars and other less evolved planets as
future abodes.

> The sun is a safe enough distance away so that its harmful radiation is

So you are saying that it is the distance from the sun that makes our
atmosphere filter the harmful radiation? How does the distance from the sun
make our atmosphere more effective at filtering the radiation that gets
here?


How do you know that the earth's center is converting matter into energy? Is
there proof?


How do you know that the earth is getting bigger and hotter? Why do you want
to maintain human and other life species? Would it be worth the cost? Is it
your plan to moive 6.4 billion people plus pets, etc. to another planet?


But I claim that they are getting smaller and cooler. I think I will stay
here.

thats a good idea don.. you go live on the moon or mars

sun

The distance attenuates the radiation intensity (inverse-square law applies)
to a level low enough that the earth's atmosphere and megnetosphere can deal
with it effectively. Imagine what the situation might be like if the earth
were as close to the sun as mercury - the radiation would be 6-2/3 times as
intense.

Is

Yes. The helium in the atmosphere (5.220 ppm) is too much to be accounted
for without a continual source of helium to replenish what leaks off into
space. The helium leaks into the atmosphere from the ground (measurements I
have personally made). Helium is obtained from natural gas in commercial
quantities where the gas is trapped in the rock by an impermeable layer
called 'caprock.' The isotopic composition of this helium is such that
99.99998% of it results from the radioactive decay of fissionable isotopes
(which produce alpha particles, which capture electrons and become helium
atoms). Only 200 parts-per-billion of the helium comes from other sources.


Cooler is arguable, but there is absolutely no data to support the idea that
they may be getting smaller (i.e. more dense).

Yes... I was just claiming they were getting smaller... I never believed it!

Thanks again!

The distance is such that only a relatively small portion of the suns
energy radiation reaches Earth's surface, and the surrounding
atmosphere, stratosphere and other protective layers are able to handle
it: So that the radiation absorbed each day is able to dissapate almost
entirely each night; thereby maintaining a tolerable average.

In the event of the sun going Nova, or Supernova, no distance is safe
enough for us, but that possibility is only something still quite
remote.

Even before I learned about sea floor spreading I was inclined to
believe that the temperature and preasure at Earth's center were so
great that they could crush and fuse atoms. After learning about the
mid atlantic ridges exhuding magma; causing the sea floor to spread;
Alfred Wagoner's theory of continental drift and the existence of
neutrinos, there has never been any doubt in my mind that the larger
planets have fluid centers and are evolving toward becoming heat
radiators rather than just heat sinks.

No it's not my plan to save billions of people, but perhaps it would be
considered appropriate to save a sampling. A colony on the moon or mars
is a distinct possibility, and even within reach of tecnology.

I haven't worked out a plan but things are progressing in that
direction.

I'm sure most of us are destined to stay here, and die here, It's our
home planet. As far as cooling off: No way hoseay!

OK, it's a deal. You go off and find a new planet
to live on and we promise to stay here.
