Hi,
In Bechoros around daf 16-17 they discusses whether 2 things can occur at exactly the same time-a maklokes. I've heard that we prefer not to set up a maklokes in metzius, if we can avoid it.
It therefore occurred to me to suggest that the opinion saying that 2 things cannot happen at the same time is speaking either as a theoretical idea which must be true and even if there are instruments to measure something, at least, today, we know that can't measure to an infinite level of accuracy. Alternatively, the other view is relying on simple human perception, in which case so long as things look to humans to be precisely simultaneous then we'll consider them simultaneous in halacha. (Similar to the halacha that microscopic bug that the human eye can't see may not be halachically view as bugs.)
Are there sources that suggest my point of view?
Thanks,
Gershon
I saw exactly this idea suggested by Rav Yosef Ben Arza, the author of Yosef Da'as, who is one of the scholars of our own Kollel Iyun ha'Daf. This would appear to be the view of Tosfos (Bechoros 17b) who explains the Sugya in this way. However, Rashi would appear to be saying that the Machlokes is whether indeed it is impossible for two things to occur simultaneously, as one opinion is that on a practical level this is impossible and not just on a theoretical level. So your idea really works with Tosfos.
