there was mathematical evidence that suggested that all numbers can be expressed as a ratio of two whole numbers...
and then it was shown to be false years later
fermat had mathematical proof that all numbers in the form of 2^2^n+1 were prime...
and then that turned out false too
sorry anon, the graviton is still hypothetical

I can answer this anon.
>At a black hole's event horizon, time dilation becomes infinite. Relativity shows this.
true
>That means from any external perspective, it takes an infinite amount of time for an object to fall into the black hole.
also true
>So, the object never actually gets eaten (from our perspective.)
absolutely true
>Given this, how is it possible that we, in our current perspective, observe black holes to exist?
here is what is happening. We are not ever observing a black hole directly.
>How does a collapsing star ever form an event horizon when it should take an infinite amount of time for this to occur?
the event horizon can form in a finite amount of time. the time it take for ADDITIONAL matter to enter the black hole is infinite.
>given hawking radiation seems to indicate all black holes will eventually dissolve in a finite amount of time, how can a black hole EVER exist?
