Rabanan – Day ends at shkia (sunset)
Rebbe Yehuda – Day ends at Plag Hamincha (two and half halachic hours before shkia)
The Gemara concludes one could follow whichever opinion they decide.
Could a person daven Mincha after Plag hamincha and then daven Maariv immediately following (before Shkia)?
Would it be permitted if it was two different days?

See גמרא ע”ז דף ז. “ת”ר הנשאל (twelve lines from bottom of Amud) until “ת”ר ” (four lines from the bottom) which brings the rule ספק דאורייתא לחומרא ספק דרבנן לקולא.
Based on the above rule according to the first explanation of our Gemara why before the בת קול ruled the halacha like beis hillel was it left to the volition of the individual to decide to follow beis hillel or beis shamai. Why were they not bound by the rule ספק דאורייתא לחומרא ספק דרבנן לקולא ?
According to Rav Shizbi explanation one can not follow two chumrahs of two different opinions if they are סתרן אהדדי. Based on the rule of ספק דאורייתא לחומרא I should be obligated to follow the stringent opinion in both cases?

Does the Rambam rule like Rebbe Yochanan? Seemingly the gemara only discussed whether the door needs to be closed at night or suitable to be closed in regards to a מבוי מפולש. From where does the Rambam know that ראוי לנעול is acceptable for a רה”ר? List the different explanations how to explain the ruling of the Rambam

How can the Gemara compare the requirements for the entrance to yerushalayim to the opening between the blocks of the פסי ביראות. The entrance of Yerushalyim was 16 Amos and the size of the space between the blocks of פסי ביראות was just 13 Amos. Perhaps the Rabanan would agree when the width of the entrance is 16 amos (the size of a Reshus Harabim) we would say אתי רבים ומבטלי מחיצות

There seems to be a contradiction between “תוס’ דף כב. “והא and “תוס’ דף ו: “והאמר According to תוס’ דף כב the Rabanan hold we do not say אתי רבים ומבטלי מחיצות on a צוה”פ but תוס’ דף ו is clear that we do say אתי רבים ומבטלי מחיצות on a צוה”פ?

Yesterday we discussed two answers to the following major question: The gemara asks a question on the Rabanan how could they allow a לחי וקורה on one side and צוה”פ on the other when Yerushalayim needed it’s gates closed in order to prevent it from being a Reshus Harabim. How could the gemara challenge the Rabanan’s opinion from the opinion of Rebbe Yochanan when it’s clear from דף כב that they disagree on when we say אתי רבים ומבטלי מחיצות? Tosfos “תוס’ דף ו:” והאמר (from וא”ת) – From Rebbe Yochanan opinion of when we say אתי רבים ומבטלי מחיצות with only four partial walls we can learn that the Rabanan should also say אתי רבים ומבטלי מחיצות when there are just two complete walls. Ritva דף כב. “כאן הודיעך – The Gemara is ruling like Rebbe Yochanan when we say אתי רבים ומבטלי מחיצות but rules like the Rabanan in regards to the minimum amount of walls needed to create a Reshus Hayachid.
Major Question: Why should Yerushalayim need doors closed at night;Yerushalayim had four walls so according to Rabanan we should not say אתי רבים ומבטלי מחיצות and since it had two whole side walls we should not say אתי רבים ומבטלי מחיצות even according to Rebbe Yochanan?
