Just to note that is the definition of tension. It's the force transmitted; not twice the force transmitted! -
jbriggs444 replied to the thread I Topic about physics axioms, theory, laws etc...We are not talking about events that occur in the same place. We are talking about an event occurring at Westminster Abbey (e.g...

No, that's not true. Simultaneous events that occur in the same place remain simultaneous with respect to all reference frames... -
jbriggs444 replied to the thread I Topic about physics axioms, theory, laws etc...Since the rest frame of Westminster Abbey is rotating, that leaves some remaining troubles with simultaneity.

And fundamentally that is why the scientific method can never be said to “prove” a theory true. It is an inherent limitation of the... -

They didn't use a speed. They aimed to measure the change in speed relative to the ether over a year, and found a null result.

OK. So now let’s change it. Now let’s suppose that we have just encountered a flubnubitz for the first time. Like a coin a flubnubitz...

I am totally satisfied with Newton when I start my car, although I know he was wrong.

I have an ordinary coin. I make a theory that says this coin always lands “tails”. I perform an experiment and it lands “tails”. Have I...
