Closing reposts of closed, poor questions as duplicates of the original question
It seems that this is a case where the close reason text from the SE engine is currently unreasonable, which possibly should be addressed on the SE mother meta site.
E.g. it often happens that a user ...

Why is this question about "non-maintstream physics"?
Don't bother. These gatekeepers close questions to get their "fix" of stars, points, or whatever StackExchange gives them. I've asked some "how do you do this type of physics" ...

Should any check-my-work questions be made on topic?
This is absurd. This is gatekeeping at its finest. This used to be, albeit years ago, somewhat of a source of supplement and support for those struggling to understand topics, derivations, etc. Not a ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
To add to the noise, I agree with the goal of this post, but disagree with the reasoning presented.
They have spent time and effort on it. They have hopes that they have discovered something new and ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
Perpetual motion proposals always involve a misunderstanding of some physical principle. As I understand it, clearing up such misunderstandings is the entire point of a physics Q&A site. Just as ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
Every so often somebody posts a question about a new perpetual motion machine they have invented. They have spent time and effort on it. They have hopes that they have discovered something new and ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
Here is the simplest and most intuitive answer I can think of:
Just as in banking, physics has a short set of very basic rules you must follow so your books balance at the end of the day. One of these ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
I think it is about the amount of effort, and that it is somewhat necessary.
By that, I mean that
Conservation of Energy (CoE), and
2nd Law of Thermodynamics (2LoT)
are the fundamental building ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
A perpetual motion machine is something that does some motion over and over. And with each repetition, it has more energy that before. Usually the idea is to remove that energy and do something useful ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
It's always good to be polite, and I'm sure most of us don't delight in hurting people's feelings. But at the end of the day a question about a perpetual motion device is not a question about physics ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
I have nothing against perpetuum mobile problems, when phrased properly they are very educational. One of my favorites was given by the late Professor Paul Penfield, probably not well-known to ...

Why do physicists say a proposed perpetual motion machine won't work without even looking at it?
I think the question is more appropriate for meta. A short answer is: a perpetual motion would violate energy conservation and/or the laws of thermodynamics.
Now, we can speak of a caveat that ...

Why am I getting downvoted in this?
I imagine you are getting down votes because your second paragraph:
Also, universe is explosively expanding. It's almost impossible that the star remains will come close enough to form new stars. (...

Why is this considered off a topic personal theory?
Voters of this site tend to get itchy for GR-related questions. Only they know, why. Also I had already trouble with their this behavior.
I suspect, they might interpret it as the covered propagation ...
