Times have changed indeed, now that Obi's posts are the most interesting in a thread. Less asterixes anyway.
This is very much what Descarte is all about when he says 'I think, therefore I am'. How can we believe that which we see around us is actually what there is? How do I know that I am not just being decieved by a higher power?
Well, the one thing I know for certain is that I exist for I am able to ask these questions. I must exist because I am able to think. This assertment is not based on deduction, but rather because it is self-evident.
However, I only know that I exist, I cannot tell for certain if anything else or any other minds exist. How then can I assertain the truth of that which I sense? Well, while my senses may well be decieved by a higher power, I know for certain that I am a thinking thing of sorts. Perception may be decieved, but deduction cannot.
Science was shaped by philosophers and as such science is spoken not in the language of perception but the language of deduction. Science does not describe temperature in the way that we percieve it (a chemical reaction is not described by "ooh, that's very hot") but rather the way we deduce it. Mathematics. Mathematics is built upon the logical progression of that which can be deduced (mathematics does not require you to be able to 'see' it; you can work in however many dimensions you want, despite existing in only three), and is the language that describes science.
Well, you have to understand that the concept of 'force' does not correspond to any observable quantity, it is entirely derived from the momentum. Newton used the concept of force to derive equations of motion in the form that we now call Newtonian Mechanics. But there is no reason for you to be limited to Newtonian Mechanics, you can work any problem in Lagrangian or Hamiltonian Mechanics; and you can derive equations of motion without the concept of force (using only the kinetic and potential energies).
We don't need experience from 'outside' the Universe to validate our own. As far as we're concerned, the Universe is entirely self-contained and is entirely all there is (quiet at the back, string theorists).
Religion wishes it could ask questions that science or philosophy cannot answer. It hasn't, yet, and instead beats away at all the ones they already have.
