Wouldn't vs won't and don't

Hi,
"The physics of fluids in micro-gravity is not completely understood
and in space fluids can be mixed combined almost regardless of
their relative weights (unlike on Earth) .
Researchers also want to study the combination of fluids that would not mix
well on Earth."
Would it be possible to use 'won't' or 'don't' instead of 'wouldn't' in the same context? How would the meaning change?

Thanks

" That suggests the researchers are theorizing about those liquids; they haven't tried to mix them yet. "Don't" or "won't" would imply that we know for a fact that those liquids cannot mix (on Earth).

But the scientists are in space because they want to test what they have tried to do on earth and didn't work. I mean they know for sure which liquids are miscible with other liquids and which are not; that's why they want to check the same experiments

That's another possibility. However, the original post didn't clarify that the researchers were actually in space. In any case, "would" is tentative.
