Bloody hell, this is getting basic!

It is NOT a circular argument, try to keep up with stuff I learned as an 11 year old.

Positive energy = E=mc

^{2}

Negative energy = m M

_{u} G / R

_{u}

*IF* positive energy = negative energy

*THEN* mc

^{2} = m M

_{u} G / R

_{u}

Now you substitute values for the terms in the equation

*and see if really do equal each other!*

Trixie uses the word "if." The word "if" is required. She is assuming the two equations are equal. i deny this

The word "if" means I am assuming nothing!!!! That's what "if" means!

*IF* the two equations are equal then when you plug in values for the terms you will get the same answer for each equation.

*IF* they are not equal you'll get different answers!

The auther of the website in question doesn't say that E=c

^{2}. He is dividing both sides of the equation by a common term, namely m.

If you leave the minus sign in front, then the sum of the two sides of the equation will equal zero

*IF* the equations are equal. If you remove the minus sign, then

*subtracting* one value from the other will equal zero if the equations are equal.

Can we at least agree that the following is true?

*IF* 2ab=4b

*THEN* a=2

and

4+(-4) = 4-4

If you're struggling with algebra as basic as this and think that this basic algebra is circular reasoning

why on earth do you think you are able to determine if theoretical physicists are wrong?

Anytime I am not persuaded because I don't understand something, I think the honest thing to do is to state what I don't understand. Perhaps someone can explain it to me and increase my understanding.

**I also provided evidence to show why the portion I did understand indicates the author is wrong.**

Note the part that I bolded. Has it occurred to you that if you only understood a part of what the author is saying, then you don't actually understand what he

*is* saying in toto? If you don't know what he is saying, i.e., what case he is making , you have no way that you can objectively determine whether he is right or wrong.
