I assume this is just trolling, but I still want to answer it since I'm pretty awesome.
Large astronomical objects like stars and planets are not held together by chemistry (positive and negative charges), as is the case for objects like apples, but by gravity (i.e., mass).
A star is a hot gas forced into a roughly spherical shape by gravity with a radius that is a function of its mass and temperature, i.e., its gravity tries to compress it and its thermodynamic properties tries to expand it.
So, what's this mean? It means if you were to partition a star into multiple parts and separate them by some relatively small distance, each part would expand (due to gravity and outward thermodynamic pressure no longer being in equilibrium) and each part would also be attracted to every other part, thus gravity would force it back into a sphere. It would quickly evolve towards its previous equilibrium state, e.g., it would have the same radius as it had previous to the partitioning.
Thanks for sharing this. It is relevant, because there is a lot of hot gas around here, held together by pure hate.

No. This is bad science. The existence of solar flares disproves your thesis. Solar flares do not fall back into the sun, they are ejected far out into space, sometimes even hitting the Earth!
I mean the Earth is clearly flat, but is the Sun flat as well? If so, it should be easy!

Knife would melt, no matter how big, no matter how sharp
Next question?
what if the knife was as big as the milky way, and was made out of bear claws?
The question is wrong. It should be that if you were big enough could you could cut the sun in half. Sure. We get that big all the time. Anything is possible to someone who understands the laws of the universe through reading only comics.
You do know the sun is made up of
gases, right? Hydrogen and helium, mainly. And you can routinely cut gases with a solid object like a knife. The OP has to win ignoramus of the year.

At least someone's thinking here
What if the knife was made of the moon?

In other words, you need a big ice cream scoop, not a big knife, and you're gonna have to fling the scoops of sun away, so that they don't rejoin.
Very interesting question?
But it leads to more questions:
How hot is the sun?
How high is the melting point of your steel of your knife?
Another way it could be done is if the knife was really big and had two blades, each much bigger than the sun, and you put the blades on either side of it so their gravity would pull half of the sun one way and half the other.
That's not technically cutting the sun, but it also means you don't have to worry about the knife melting until after the sun is cut.
If you had a big enough knife yes..
The knife would have to be so big that it was a scale equal to a butcher's knife vs. a pea
It would have to be swung so rapidly enough that the tiny sun would not enough heat or time to melt the entire knife before it either crushed it or sliced it into two
This guy is saying the sun is actually liquid hydrogen not gas. Pretty interesting huh?

Interesting. The energy required to swing a hypothetical solar knife would probably destroy the earth

You couldn’t pull off parts with a knife. You would need to use an extremely, incredibly, hugely, epically dense object that would attract some of the mass from the sun over to it. A black hole or another sun could do it. Or maybe (insert name here)’s brain?
