Actually, I think that's something me and kennethamy agree on. We both think that a billion gallon river of cola is possible but no person will ever be wasteful enough to make one.

Indeed, and I am certain a snowman has never been made on Mars.

Yea, so if it's possible, it's happening. If it's not happening... that tells you it's not possible. Can you detect a possibility field?

No, that's not what is meant. If something is physically impossible then it can't happen.

That is right. If it is true that relativity theory implies that nothing can travel faster than light, and if relativity theory is true, then it follows that nothing can travel faster than light. Relativity theory and something faster than light are incompatible. Just like something's being a snake, and being a mammal are incompatible. What is physically impossible cannot happen because it is inconsistent with physical theory. (Not, of course, because it is self-contradictory that it should happen).

You mean it wasn't logically possible in the first place?

The problem here is what one grants as logically possible... without ultimate cause logically possible is a metaphor...

What is logically possible a metaphor for? X=?

If it is true that relativity theory implies that nothing can travel faster than light

Description of X IS INSUFFICIENT not wrong, wrong is the conclusion..."X" refers to X for "gravitational" proximity...metaphor fills the gap between what one can intuitively apprehend as X but that one cannot objectively define to the full...

Which it's not. You're forgetting the distinction between does and can.

But if relativity theory implies that nothing (does) go faster than light, then it is physically impossible for something to go faster than light. That means that something's going faster than light is inconsistent with relativity theory. A physical theory. What do you think it means?

The problem here is what one grants as logically possible... without ultimate cause logically possible is a metaphor...

metaphor for what?

A "metaphor" for expressing the Intuition on X which is apprehended as whole but that cannot be explained to the full...

metaphor for what?

So you're using "physically impossible" to mean "inconsistent with relativity theory" instead of using "physically impossible" to mean "can't happen"?
