Beanz, I have already defined level. It is your concept that is flawed and doesn't match reality. In reality, level doesn't mean curved.

You can test the tangible substance for yourself. The physics of the substance don't change. I can prove this using the scientific method, I can make predictions about the substance, test it, demonstrate it and repeat it.

All you need to do is practically demonstrate a standing body of water, showing the surface to be naturally bending.

You have already adimitted you can't, so we are done.

I've dealt with the likes of you for almost 4 years, so I don't care for the back and forth. Practically demonstrate what you believe to be true, using the tangible substances, because I don't deal in pretend.
