I’ve certainly enjoyed our conversation on the topic.
I think where we may differ is that, while I will not outright and conclusively state the impossibility of (say) the Bold Street time portal, I cannot say that I give any credence to the claims whatsoever. I see it more as a very abstract (but fun) philosophical question than something that would inform my day to day mindset. I get the sense that you are far more open to the possibility than I but I may be wrong.
I’m sure that you and I both engage in the weighing of evidence. For me, and re Bold Street, the evidence in support of the claims is so vanishingly slight compared to the evidence against that the possibility that actual time travel (or similar) has occurred is so remote that it is not worthy of serious consideration.
It would be helpful, for me to better understand your position, if you could put a very rough percentage figure on your perception of the likelihood of time travel (or similar) having occurred specifically on Bold Street, in the manner described. Although my question is specific to Bold Street, I accept that other claims of time slips (like the one in the OP) are relevant evidence.
So far as I have been able to tell, there are no first hand accounts available to read, just third-party retellings that might reasonably be characterized as Urban myths - they have been collected and summarized by various publications in broadly the same manner, so I don’t think you’d need to read far and wide by any means, I just think it would be more appropriate for you to pick a source or two than have me provide them.
Just to confirm, I’m not trying for a ‘gotcha’ or anything like that, I think our chat is approaching an end, but I think a % would help me better understand your mindset and I have no intention of critiquing it. I also appreciate that a % might be a very difficult form of measurement and that whatever answer you give today might be different tomorrow and the day after.
For me, and my subjective perspective, the odds are a very small fraction of 1%, probably more like 0.0000000000000000001%, if not slimmer.
Thanks in advance for indulging me, if you choose do so, otherwise thank you for discussion.
