    Re: false equation

    "x+3=x" is not a correct equation. There is no number, x, that you can add 3 to and get the same number.

    Re: false equation

    Time dilation is too difficult to for a beginner, man. hhtt21, if you want to use "false equation", go ahead and use it. People say "jumbo shrimp" all the time so I'm sure "false equation" is nothing in comparison.

    'False equation' is fine and natural. 'Equation' means

    An equation asserts the equality of two expressions. It can be as false as the assertion that Moscow is the capital of France.

    From this I have concluded a result that Americans and Brits think differently on this issue so this might be a difference between AmE and BE.

    Thank you.

    I think that is a false conclusion.

    In both American and British English, an equation is an assertion which can be either true or false.
