IA3 Research Investigation

Jett5698

I am currently doing my last piece of internal assessment for Physics, the IA3 Research Investigation and was looking for some tips for my assignment.
The claim I am working on is: “The Big Bang theory remains scientifically unchallenged and should now be considered a fact” and I am struggling with my rationale and research question.
The research question I have so far is:
"Can the Big Bang Theory be considered fact without a new theory of Quantum Gravity?"
This is the research question I have come up with but realise I might need to change.
Any tips or help would be greatly appreciated.

"Does the absence of scientific evidence to the contrary prove that the Big Bang Theory is the only valid explanation for quantum gravity?" It isnt perfect i dont have much context on it still in unit 2 but ye just came up with that, hope it helps.
