question.

where in nature do objects move in a straight line unless acted upon by an outside force?
not in nature certainly.
not in the observable universe.
there is nowhere in the universe, and therefore in nature, for an object to move free of outside forces to prove the hypothesis that an object moves in a straight line unless acted upon by an outside force.
yet we`ve used that as the basis in science for everything else as fact and made some bold absolute statements as a result.............like the thing about the speed of light.
so we have to have faith that science is right about things and head towards increasing global issues and wars and diminishing food supplies and so on and not continue to question things.
sounds a bit like religion to me.
like the pope says, just wear a condom.
