Good question. I'm not sure the sun is one of our real suns. Perhaps that sun simulator the Chinese launched is what this local sun is. I've heard, from a well-connected person that the sun "is not hot." I also believe we are in a binary star system, one being a dwarf star that never ignited, and of course we have a central sun. Don't know where that is and why we have a fake local one.

I'm sure...
the sun is not what they tell us... Jjst like the moon, planets, space... everything is different... maybe there is no universe at all...
maybe there's something in the form that quantum physicists talk about, that there's nothing we can't see...
