Try to measure it! Try to design a measuring device for infinity and
come back when you're done.

So things only exist if we can measure them? How do you know that?
Do you think that only what is measured is real, and only what is real
is measured?

We, scientists, employ a different - and quite succesful - kind
of knowledge: empirical knowledge. Better get used to it.

I have no problem with empirical knowledge. But the question was
whether you only think something exists if it can be measured.

Allright. I shall relax the requirement. Is it possible to devise
a physical experiment which can decide between the outcomes of a
theory which does invoke actual infinity and a theory which does
not. My stand is that there are no verifiable theories in physics
which can not live without actual infinity.

Can you answer this question? Which interpretation of special relativity
is the correct one? The geometrical interpretation, or the ether based
interpretation. Or in other words, does a 4-D space-time exist, or does
an ether exist?

Off topic, I suppose.
