[Hank Kerchief]

So are you another one of those whose still waiting for more data on whether or not heavier than air human flight is possible?

Just wondering, since you don’t think its been proved that it is possible.

"Proof that something is possible?" You are correct, anything is possible. That is why scientific theories can't be 'proved.' They can only be demonstrated to our satisfaction or limits of our measuring ability.

Now on the other hand if there was a scientific theory that Man couldn't fly, then all it would take would be one man flying to disprove that theory. That is what falsifiable means and that is the basis of Scientific theory.

When I pick up a rock and drop it, does that 'prove' the Theory of Gravity? No, because all it would take is a single instance of the rock not falling and that would disprove gravity.

So my question to you is this. Has Newtons Theory of Gravity been proved?
