  • Well, that was an entirely unnecessary and lengthy correction to a mistake that was A) a typo I didn’t notice from using swipe on my phone keyboard, not a misunderstanding on grammar, and B) not an error that rendered my comment confusing or indecipherable requiring your clarification. But thank you for your (air quotes) help. I really hope that you’re a bot, not a person this annoying or one who writes that way.







  • I’m really not even a little bit following what you’re trying to say. What units are you using? What does the Sagittarius A* have to do with anything? What scale factor are you talking about? Mass? Volume? “Mass of electron cloud equivalent to black hole” what electron cloud? Where are you pulling these numbers?

    Mass isn’t what determines if a singularity forms. Density is. Enough mass has to be formed in small enough volume to form a singularity. Mass more most matter would have to multiply by many many orders of magnitude for a planet to form one. Adding a single election to each atom doesn’t do that.

    Maybe charge can play a factor, but I don’t really have any idea how exactly or how significant it is.


  • In the example in from that what if, they are putting a universe’s worth of mass in the volume of the moon, so it would create a super massive singularity. That’s not what is happening in here.

    If every atom suddenly gained an electron, they would indeed increase in mass. But a hydrogen atoms would gain the most relative mass as it is the lightest atom, and that would only be an increase of 1/1837th of its total mass now, so… not that much. Masses of heavier atoms and the macro level matter made from them would increase in mass even more marginally. It would be a negligible difference, definitely not be enough for a singularity to form from this increase alone unless a star’s core were already riding that edge.

    So their original determination would still be correct, that molecules would fly apart (atomized) and explode outward into the vacuum of space. Now, maaaaybe if the explosive force were enough to cause atoms to collide in space and at relativistic speeds, tiny singularities might form. But their combined negative charge would be far more powerful than their gravitational pull, and they would decay almost immediately, so… no crunch.

    Grain of salt: I love physics, but I’m not a physicist.

    You know how when you put magnet faces together with the same polarity, they push against each other. If you squeeze them together they will pop away. When an atom has an extra electron, it makes its charge more negative. If all of the atoms have extra electrons, all of their charges will be more negative. Now imagine every single atom in the universe was suddenly the same polarity and began pushing all other atoms away. I’ll let your imagination take over from there.
