flaws with binary star nibiru theory

[Chaseinyaface Profile]

How could our young sun have a binary star that could be roughly 5 billion years older than itself? One would have to think that binary stars would need to be birthed at the same time. Also, nibiru is claimed to be a brown dwarf star but a brown dwarf is too low in mass to sustain hydrogen fusion. And could only get up to about 80 Jupiter masses or 3200 earth masses. Which would not be 4x the size of our sun as stated.

I suppose it would be a little more likely if nibiru were a white dwarf and we were orbiting it, but still be a very rare occurrence for our solar system to be captured by this rogue star. and previous reports I've seen stated that Saturn has been turned on its side but how could the spin of the planet be altered and not the orbit? Wouldn't this thing just be flinging planets out of our solar system?
