Time travel??? Mainstream science guys invited:)

Can you elaborate to what extension?
Both directions?
Only in context of default passage of time?
Living things have life energy .
Hence thinks .
Rocks don't think . They exist .

Besides the worm holes and black hole stuff. Yes time dilation is a thing.

I have concluded from that, that living things think, therefore they can perceive passage of time.
And that is what you mean by saying:
Time travel is only possible with living beings.
From:
Time travel is not possible...
I conclude that you do not believe that time travel (traveling forward or backward in time) is possible even for living beings.
It is based on your personal assumptions set.
Have I understood you correctly?

Would you classify that as theoretical speculation rather than actual possibility?
(worm holes and black hole stuff and information transfer back in time)

Cooper could not be in two places at once. In the black hole and somehow in the library.
"Inside" the black hole is not based on anything scientific.
The Einstein-Rosen bridge would not just just sit there for months/waiting for a craft to come through.
Time as another physical dimension I have read, somewhere but again very speculative I think.
Time dilation due to gravity is fine, not sure about distance to the ship though. If the gravity was that strong on the surface?
Would the crew not be incapacitated in the water?
Craft able to manoeuvre? Land? Leave again? Mother ship in a stable orbit? Where? Minutes away?
Would we? I mean, how fast are we traveling through the universe now? In relation to what?

"Interstellar is generally considered to be scientifically accurate..."
Your stance is that that accuracy is exaggerated in some extent.
I agree.

Or absent.
The light around the BH I think is supposed to be how it would be.
Inside is just made up.

The atomic clocks used in experiments to show time dilation happens are not living and don't think.
Three atomic clocks are synchronised at the start.
one stays stationary, the other two go on jet rides.
At the end of their journeys, all three are checked against each other and are found to be out of sync.
Google 'Atomic clocks and jet experiment'

If you could share your ideas it would be greatly appreciated.
You have invoked experimental data that could have different explanation within his assumptions set.
It would be nice, if you would comply, with what I have politely asked for.
River have not stated his assumptions set explicitly, so it makes a little bit harder to try to challenge only internal consistency.

You are quoting yourself. This makes it difficult tell what you are asking and whom you are asking it of.

First quote is foghorn.
Then I quote myself as I think foghorn have not read it.
Or not carefully enough.
You have attempted to challenge internal inconsistency.
I have no objections to that.

If you want, I can show you an experiment done in the back of a camper van that is concerete evidence of relativistic time dilation, per foghorn's summary. But I'm not entirely sure that's the direction you want the thread to go.

I think you or someone else have already mentioned that experiment. I have checked it out.
If someone have different assumptions set they operate on, then bringing up experiments is tricky because you may have various interpretation of experiment, various proposed mechanisms.
This leads to pointless arguing.
More interested with finding out how many different points of view there are and how someone got there.
More interested with what someone thinks than who he would disagree with.
And to challenge someones idea internal consistency you actually have to make effort to try to understand it.
Simply disagreeing, because it is different then ours is effortless.
To the extent that a brain compares information about its environment and the state of its personal thoughts/feelings with another similar set of [stored] information, and detects a change between the two -- designating one as "current" and the other as "past"... Then the contrast of one different cognitive evaluation like that to another "seems" to already be the case. I.e., the average person may construe themselves as "traveling in time", moving from moment to moment (transitioning from one sensory state of the outer world to a slightly altered configuration).
But if what you're desiring instead is to radically "jump" from one evaluated state of affairs like that to another one that is measured as being days, weeks, months, or years away from what's judged as the current one -- without having to cognitively "pass" through the intervening changes or differences between the two "widely" separated conditions, then... That's very unlikely to happen (if not impossible) as far as one's physical body making such a jump.
Psychologically, though, an individual in a deeply comatose condition could wake up in Rip van Winkle manner (prior to looking in a mirror) and discover they have subjectively leaped over a sequence of many changes "instantly", albeit the conclusion not being justified from an objective standpoint.
Similar with cases like Henry Molaison and Kent Cochrane. Perpetually locked into the view of a younger version of one's self repeatedly making contact with the future, but constantly forgetting that misapprehension and re-encountering it again and again.

EXCERPT: We measure time by our memories, and thus for Henry, it was as if time stopped when he was 16 years old, 11 years before his surgery. Because his intelligence in other non-memory areas remained normal, he was an excellent experimental participant. He was also a very happy and friendly person and always a delight to be with and to assess. He never seemed to get tired of doing what most people would think of as tedious memory tests, because they were always new to him! When he was at MIT, between test sessions he would often sit doing crossword puzzles, and he could do the same ones again and again if the words were erased, as to him it was new each time.
With respect to speculative fiction accounts of "time-travel" in a physical "big jump" context, that's not even allowed in one of the three or four usual options we have for time conception. In presentism, there are no past or future intervals to transit to (only a global configuration of "right now" fleetingly exists). And it's actually the commonsense view that most people on the street are supposed to be entertaining.
The others are eternalilsm, the growing block universe, and the rarely examined "shrinking block universe".
So in terms of the putative if not imaginary average person's beliefs, time travel is excluded by default. Even the ordinary kind of presumed time travel -- of speciously "moving" to the next moment or different state -- is gone. Since that moment doesn't exist yet, and the one prior to Now. When the next does, it replaces the latter (annihilates it). There would be no "travel".
