    Neutrons are charge-less particles.
    During radio activity, the expel an electron (negatively charged particle), and they themselves get converted into a proton (positively charged particle).

    'As you said the lighter elements move towards the centre according to nebular hypothesis but the outer elements such as Jovian planets (Jupiter, Saturn, Uranus and Neptune) are also formed by lighter elements(Hydrogen and helium etc), which doesn't make any sense for the nebular hypothesis because these planets are the outer planets'

    @TomHendricksMusea 2 роки тому +1

    Psy phy physics from a sci fi writer! THE LITTLE TEAR!
    During the Big Bang, Dark Energy broke out of Dimp, the singularity before the Big Bang, and started the universe. But did it explode or tear???
    Photons made the first pair conversion, and it tore into nothingness and nudged space apart. This made more Dark Energy / vacuum energy - expansion began! Consider this the first grain of rice on the chess board analogy! The second pair conversion expanded space more. Every point of new space made by more pair conversions, allowed more space and vacuum energy that allowed more pair conversions to pop up. Soon pair conversion was not a single Big Bang event, but an explosion of pair conversions as space ballooned up exponentially. This started a recurring cycle - the first pair conversion made more space, which made more dark energy / vacuum energy, which made more pair conversion, which made more space .... Finally let's rename it the LITTLE TEAR instead of the BIG BANG!
    LITTLE TEAR IN SPACE. Photons that are outside space-time, enter our universe of space-time, and make a pair of particles that expand in opposite directions! This TEAR IN SPACE, EXPANDS the UNIVERSE and MAKES A BIT MORE ROOM! That suggests that PAIR CONVERSION creates SPACE!!! The pair annihilate almost immediately, MOST of the time, and that SEWS UP THE TEAR!!!
    The pair of particles tear space time apart with both the creation of space and distance between the two. Photons in eternal Dimp, through pair conversion of positrons and electrons, create distance, space, and time!
    But even though pair conversion usually does not last, it did during the Little Tear, and sometimes it does today too because we know that DARK ENERGY continues to expand the universe today; and IT'S GOING FASTER! So the Big Bang, or better yet, the Little Tear, is going even stronger than ever.

    Actually the expanding universe comes from solving Einstein’s field equations. That is application of General relativity. The solution was done at first by Friedman. George’s Lematare proved the same independently and Hubble also proved it two years later.

    The universe is expanding. Over time ang distance sa galaxies between one another kay naga-broader and broader. Pwede ni ma-project by using a balloon. Mark some parts of the balloon, and put an air in it. Katong wala pa nimo gipaburot ang balloon, dug-ol pa kaayo ang marks/spots. But then katong gipaburot na nimo, while you are slowly putting air into it, slowly pud na naga palayo from each other ang bawat marks/spots. Gets? You have done this experiment earlier this year, I guess? BUT WALA PAY EVIDENCE ANI NA THEORY HEHE.

    (Sahih International)
    Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?
    -Sura Al-Anbya, chapter 21, verse 30
    وَٱلسَّمَآءَ بَنَيۡنَٰهَا بِأَيۡيْدٖ وَإِنَّا لَمُوسِعُونَ
    (Sahih International)
    And the heaven We constructed with strength, and indeed, We are [its] expander.
    -Sura Adh-Dhariyat, chapter 51, verse 47

    I have a question to ask ..... IF there is nothingness at the edge of the Universe, then can one surmise that the Big Bang theory is still happening when and where the universe occupies that space? The math would suggest so
