Is Earth going fat or going slim ? How much Earth lose each year from atomic diseintegration (turned into energy as heat in the center of Eath), compared to the star-dust fall ?

None. The Sun is presumed to be a fusion reactor, the Earth is sub-critical. The heat is from decay in the outer electron rings, IIRC. Doesn't affect mass.

edit:
Nobody going to call me on that? I was skeptical so I found:

Quote:
And Earth is chock full of such radioactive elements—primarily uranium, thorium and potassium. Over the billions of years of Earth's existence, the radioactive isotopes have been splitting, releasing energy as well as these antineutrinos—just like in a man-made nuclear reactor. That energy heats the surrounding rock and keeps the elemental forces of plate tectonics in motion
[snip]
The new measurements suggest radioactive decay provides more than half of Earth's total heat, estimated at roughly 44 terawatts based on temperatures found at the bottom of deep boreholes into the planet's crust. The rest is leftover from Earth's formation or other causes yet unknown, according to the scientists involved. Some of that heat may have been trapped in Earth's molten iron core since the planet's formation, while the nuclear decay happens primarily in the crust and mantle.
So, TLDR: Trapped heat in the core (maybe) & sub-critical decay in the crust.

Sorry 44 terawatts (44X 1000 gigawatts) it's nothing compared to the energy that moves tectonic plates. The Tzar Bomb (50 megatons) can't even be compared to earthquake energy released or a hurricane or tssunami energy.
Comopare tectonic plates energy with 40 terawatts it's like try to use a single wristwatch battery to move a large electric truck.

Wrong use of vaccines can be harmfull.

The vaccine against dengue fever have low succcess rate, just 60% or so, since dengue fever is caused by 4 virus variences. You need to get 4 virus infections to be completely naturally be protected against it.
And the worst is that if get dengue fever 1x time, there is low danger of hemooragic fever (danger possible fatal), but in a second or in a third time, the risk to get hemorragic fever rises a lot.
Guess what, the s... vaccine works in the same way like the virus, if you take a vaccine shot without had got dangue fever of any kind, the risk of you get a hemorragic fever reaction, if you get infected by dengue virus, it's higher if you had took the vaccine before.

Conclusion, the vaccine against dengue fever took money, years, and it's a garbage, since have very low efficience (60% or less) and can help people get hemorragic fever reaction. It can kill more than can save, since dengue fever without hemorragic fever rarely kills, and dengue fever with hemmorragic fever reaction can easily kill someone.

We're going through the same "issue" with Dengvaxia.

Guess what? While people are wringing hands over fourteen deaths that were purportedly caused by vaccine reaction (it was later determined they were not), we had hundreds fewer deaths from Dengue than the previous year.

Yes, the vaccine must be used properly. But it is hardly merde. And it is not useless.

You took all wrong my text. First I refered about yellow fever, and deads of vacines applied in areas with no cases of yellow fever and not mosquitos on city carrying the virus. Just wild mosquito in country areas had the virus.

Then I refered about Dengue Fever, for which the vacines increase the risk of a body reaction know as hemorragic fever, a reaction that also happens much more often in second and third or forth infections of dengue virus, since it's related to strong imune response.
Dengue have 4 virus variances, and so you need to get the natural virus infection 4 times to be completely imune, and each time you got it it's more dangerous, more risky to get a hemorragic fever reaction.

The dengue vacine not just have only 60% efficiency (poor), but also can make people prone to hemorragic fever reaction in the same way a earlier virus infection can make people more prone to it in case of a second infection.
So the vaccine it's dangerous in some way.

AND IT'S NOT JUST ME. The health authorities themselves said that people who never got dengue SHOULD NOT take the vaccine.

Got it now ?

Take that up with Scientific American.

It's a summation of the residual heat left by trapped heat and radioactivity, not the energy available to move things.

There's no radioactivity at the core, apparently, because it solid iron.

Would could be generating the other non radio decay heat?
How about an earth size magnet in a sun size magnetic field, kind of jumps put as a possibility.

Solid?

I'd expect lead, gold, platinum, and other dense materials to be in the core of the core.
