Lupini, cum au ajuns ei sa calculeze soarele la o viata de inca 5 miliarde de ani?

Cum explica stiinta de azi faptul ca sun spoturile sunt negre in loc de luminoase, incandescente?

Ti-a dat poza zen. De ce este negru un sun spot si nu este luminos? Negru nu este cumva asociat cu intuneric? Se stie ca prin sunspoturi putem vedea adanc in soare? Soarele este deci intunecos si rece pe dinauntru?

Sunspots are temporary phenomena on the surface of the Sun (the photosphere) that appear visibly as dark spots compared to surrounding regions. They are caused by intense magnetic activity, which inhibits convection, forming areas of reduced surface temperature. Although they are at temperatures of roughly 3,000

si... o poveste mica pentru cititorii de Engleza:

Imagine you grew up speaking fluent Mandarin, as well as English. And you'd spent a lot of time in China, living among people in many different parts of the country.

One day, probably somewhere in the US of A, you come across someone giving public lectures on how to understand Mandarin. Lots of people are interested, it seems, because Mandarin is still quite alien to most people in English-speaking countries, yet it's a language that may prove increasingly valuable to learn for the future. You're curious, so you take a look.

What you see is someone making stereotypical Chinese-sounding noises. He utters words that sound vaguely Chinese, and explains what he thinks they mean. He tells his audience that he's studied this language for many many years, and has learned things that most teachers of Mandarin would never even realise. You do recognise some of his words, but they're not put together in a way that makes much sense to you.

You ask his students, who proudly tell you that this is the true Mandarin, and that what they teach in language schools is flawed. When you take issue with this, they insist that obviously that's because you're only able to see what you've been taught, and you've never thought outside of this box, and if you could see the bigger picture then you'd understand what he was saying and what a revolutionary understanding of the language it was. And the reason no other teachers of Mandarin teach this way is because of a massive conspiracy to put down creativity and keep the language in the control of the elite. Or something like that.

Anyway, who are you to tell people how they should speak Mandarin?

He has thousands of followers, and they all happily believe this is the true Mandarin. What do you do?

Poate nu stii pe ce principiu functioneaza Bomba H - bomba cu hidrogen... Exact ! Explozia aia imensa e posibila datorita fuziunii care e o reactie in lant producandu-se practic instant !

Principiul de funcţionare a bombei cu hidrogen e fuziunea. Ce este fuziunea ?

Să luăm atomul de hidrogen şi pe cel de heliu. Atomul de hidrogen e compus dintr-un nucleu format dintr-un singur proton, adică are un nucleu cu masa echivalentă cu un proton.

Acum să luăm atomul de heliu. Acesta e compus dintr-un nucleu format din doi protoni şi doi neutroni, nucleu care are o masă nu de 4 ori mai mare dec

Stiam de tot ce se zice in linkul ala... iar eu n-am afirmat ca Haremein e vre-un mega specialist ci e o persona care propune ipoteze mai apropiate de realitatea observabila . Realitate observabila care de multe ori se contrariaza cu vechile teorii . De exemplu spre sfarsitul clipului ala de 2 minute sunt filmate flacarile solare care sunt atrase intr-o pata solara - ceea ce fizicienii sustin ca e imposibil dupa intelegerea curenta a fizicii . Practic ele cad in petele solare atunci cand trec pe deasupra . Deci nu sunt doar pete ci chiar gauri... dupa realitatea observabila si nu cea teoretica .

Trebuie precizat un lucru esenţial: hidrogenul are nevoie de temperaturi şi presiuni foarte mari pentru ca atomii lui să fuzioneze, şi asta nu se poate face dec
