Q: Would life be possible on a planet with an eternal day and night?

Deschele SchilderThe story I want to tell is about a world where one side of the planet always is sunlittenand the other side is always drenched in blank. The planet once stopped rotating (tangential meeting with a black hole). That is, it makes one rotation a year. So, when the planet was still having a day-nigh...

Have you done any research on your own?
@L.Dutch Yes. Should I include it?
@GrumpyYoungMan The evil eyeball. I think I have a new name for the story!
@rek Hi! Thanks for the link. Im new here and do anything to learn poseca good question! Ill give it a go. Its difficult to find the right focus in this case What should be my ultimate question be? I have the general story outlined, including characters. I didnt know Asimov wrote a similar story. I give it a go!
@JBH The planet I have in mind is not tidally locked. Its rotation has been reduced after a passing black hole has passed the side of the planet. There is no tidal lock yet. Or maybe the new situation is by definition tidally locked but this is not achieved Naturally.

You'll need to explain why the backstory should lead to different answers. A different backstory alone doesn't justify a new question.

@JPH What new question do you mean? If there is a differnce between tidally locked and suddenly reduced rotation?
If your planet 'makes one rotation a year' it means that your day is 1 year long. It also means that your planet does not have permanent dark and sunlit sides, those are features of tidally locked planets that do not rotate at all. Please edit your question to clarify this point.
@Otkin The planet will always be in the starlight on one side. One rotation cancelling the other.
Astronomy is not my strong point. Could you explain your idea? And, please, edit your question to include this explanation. Please also consider that if there are permanently dark and light sides, your question is not very much different from all tidally locked planet questions.

You'll have to clarify what exactly has happened and decide what one aspect of this scenario you want answered. Some questions you have may already be answered in other posts, but you can ask multiple questions across multiple posts. It looks like you're curious about adapting to this scenario, so I would concentrate on that.

For the practical purpose of answering your question, no. Why a planet becomes tidally locked (or stops rotating) is irrelevant and if it spins at all, the faster it spins the less meaningful your question becomes. BTW, "one rotation canceling the other" is what tidally locked means: one rotation of the planet per orbit around the star. If f(a) = Z = f(b), then f(a) = f(b) (aka, duplicates).

@JBH Well a sudden stop in rotation causes more damage than a slow stop. In that case there would even more evil done than for a slow stop. So the alien people would even be urged harder to go underground on the cold side (that would be my solution).

You didn't ask what damage would be caused if the rotation of your world were stopped within an unspecified period of time - you asked if life is possible on a tidally locked planet. Changing the question to an entirely new question to avoid closure is verboten.
@JBH Ich denke das du verboten werden muss...
Im gonna close this question. I cant delete it.
Can somebody please make the final close vote?
@JBH Many astrobiologists believe that such tidally locked worlds would be uninhabitable for beings like humans, or even totally lifeless There is thescientific hard evidence you asked for. Totally lifeless...
Hurray!!! Its finally closed. Pfffhhhh...
