B Does "nothing" have a meaning in physics?

I know nothing about that, I'm afraid.

 

It has no technical meaning. Just the standard English meaning. Vacuum, on the other hand, has a technical meaning.

 

Whatever a "thing" is, it is what is left over when you remove it.

 

"nothing" is very contentious in Physics, and is best avoided. "A Universe from Nothing" for example, means different things to different people.

 

Actually, now that you bring it up, a good definition of "nothing" is "the scientific value of Michio Kaku's statements on physics in the last few years".

 

Nothing is the just the opposite of everything I believe

 

And how does that work as a definition in physics?

 

I think this is what you're looking for https://en.wikipedia.org/wiki/Null_(mathematics)

 

I don't think so. That's a math thing. This is a physics question.

 

Math is sometimes employed in physics, so there tends to be overlap.

 

Of course, but I think not in this case.

 

The important thing to know is that "null" is not the same as "zero", "no value" versus "a value of zero", and so the meaning of "nothing" depends on which more specific word or definition it's making reference to.

 

Yes, that's my point. The question here is not about math but about physics and the universe.

 

Can you give an example of where the distinction becomes important?

 

Not offhand but it's important to keep in mind that, as Alfred Korzybski said, the map is not the territory.

 

Yeah, it's even hard to make a conclusive statement about "nothing".....

Just funning you .....

 

Strawberry fields forever.
