There isn’t one. That is not how science works.

there isnt definate proof of gravity

I think you don't understand the meanings of theory

to be moved from theory to fact you have to have an observable repeatable result of matter attracting mass

its just the name we give to the occourance of matter excellerating to each other when left alone

pls show me the data

sources pls

There is no experiment to prove gravity

it does however explain how a lot of things in the universe work

Then several theories will fail

Like the only one I can think of is those of black holes
