Re: DA.
It's not odd, it's just mathematically wrong. Your -0.0...1 is just a long-winded way of writing 0 - there is no difference in the value represented.
I'll add that it is nonsense to suggest that 0 equals any number greater than 0.
If your mathematics relies on either, then your mathematics is wrong.

I guess you could call it negative pressure as well. All describe the process of an outward pull which overpowered the force of gravity causing the universe to "inflate". This outward force is also thought by many scientists to be part of the mystery of dark energy.

For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.

NS is infinite, it is not '0' but in reality NS is -0.0>inf<1
I am not a mathematician and only got up to College Calculus but from my understanding there is no such creature as -0 as 0 is neither positive nor negative. Thus -0=0. Therefore -0.0=0 right? As far as 0.0000000 this is again is 0. Do you mean 0.00000001 (not -0.0>inf<1, whatever that means???)? If so then this technically would be zero as 0.00000001 could never be reached. Someone let know if I am wrong in my assumptions.

Only that -0.00000001 isn't merely technically zero. It's exactly zero. Sticking the 1 on the end of the infinite string of zeroes makes no difference whatsoever.

Thanks Paul,
I see the logic in this. It is the same thing as saying that + 1 = .

Devil --
DA, I've asked VBird not to post to this thread again.
It is my assessment that we don't need continued utter gibberish in the thread any more.
If you disagree please take that that to suggestions and questions.

Pretty much. -0.00000001/10 is the same as -0.00000001 for that very reason.
It's also exactly the same as 0.999 = 1
