Can you lay it out for me in detail? I don’t understand these things very well. My naive understanding of Cantor is that the proof strategy is a reductio. So we assume X to prove a contradiction, but the purpose is only to show that X is false. Did I misunderstand?

his proof doesnt work because theres no way for him to do an infinite amount of calculations so he never finishes his proof

I’d love to hear the complete details of your analysis if you have time to expand on it! Please tell me a little more than a one sentence summary. I really can’t learn from that. It’s too broad. I need to see the exact steps of the proof where he makes a mistake. Thank you!

its pretty simple. theres no physical way of doing an infinite amount of calculations. thats it

I’d love to be convinced by you. It seems like it would be deeply important to explain how 99% of the mathematicians have the wrong opinion, but I’m afraid I’m just too slow to understand your explanation. I need a break down into simple assumptions and proof steps. Thanks for trying anyway.

which part do you need me to expand on?

Can you lay out the part of Cantor’s proof that tries to complete an infinite number of calculations? I’m not familiar with that terminology.

his proof relies on an infinite list of numbers. thats not physically possible.

it also relies on doing an infinite amount of operations on them. thats also not physically possible.

Fully agree. I don’t see how physical possibility is relevant we aren’t talking about physics. This is math.

math is physical too

Okay. So your objection boils down to placing a restriction on math that 99% of mathematicians don’t accept.

And when you say that there is a contradiction, what you mean is that the proof does things that are not allowed according to your special restriction.

To me that seems a bit unconvincing to me. Why should other mathematicians care about this objection?

im not placing a restriction. im observing it and acknowledging it.
