if you claim something is impossible when it is not against the laws of physics (and even if it is against those, it may be possible to go to other universe!) you are the one making the claim. i am saying anything that is within the law of physics can happen.
Excelllent! Can we agree to stick to our universe for the time being? Sticking to this universe I am saying exactly the same thing you are saying:
i am saying anything that is within the law of physics can happen.
Only it turns out that within the laws of physics (in this universe) it is
not possible.
