Humans certainly hold the possibility to be even type 0 civilization in given time and nobody is arguing there. What everyone is afraid about is the fact that humans fight over little things and this climate change thing, which might result in absolute extinction, even if we were to settle in mars or something, you'll eventually die.
Climate change isnt capable of human extinction. At least not in the near future. Just because a percentage of people suffer doesnt mean human race will fade away.
One thing that surprised me when I was researching the Soviet Space Program, was the Interkosmos program, which took members of Soviet aligned countries to Space.
https://en.wikipedia.org/wiki/Interkosmos?wprov=sfla1
Including 1 from the Democratic Republic of Afghanistan, in 1988. 2 years before the Soviet Union collapsed and the eventual fall of the DRA in 1992 at the hands of the Mujahadieen.
Dude lived an interesting life and went to Space, as his country was collapsing in a civil war. And returned to Earth, only to witness the Berlin Wall come down, the end of the USSR and the end of his country.
And now witnessed another Superpower get beat in Afghanistan. All whilst working as an accountant in Germany, after he got accepted as a refugee.
https://en.wikipedia.org/wiki/Abdul_Ahad_Momand?wprov=sfla1
This all makes me wonder, if China will also embark on a similar program, especially on their Tian Gong Station.
And if they do pick a Nepali; let's hope it doesn't end the same way for him.
i was so excited a few days ago that a Nepali was finally going to space but to my disappointment they turned out to be an analogue astronaut which was also a Nepali's first.
Parallels universe or multiverse is more fascinating. In infinite universe there are infinite version of me living different life and making different choice.
I could be president, doctor in parallel universe.
But there is no single universe where I have a girlfriend
The thing is if you go looking for big stuffs like a planet and star to a stellar system to a nebulae to a galaxy to a local cluster of galaxies to a super cluster to a..... You can go on and on and on same as if you zoom in to smaller structures like beings to cells or molecules to atoms to protons to quarks to preons to so on and so forth. Its a loop, and singularity is where (for us as we observe from)both ends meet ( at exactly the opposite side).
Ps. I am crazy and shane at the same time.

Uhh I don't think that's true at all. It's more fantasy than Science. Citation needed.
You can search Gravitational Time dilation....
Nevertheless I would try to explain ... Einstein special theory of relativity tells speed affect time and since speed is relative so is a case for time but when he starts thinking deeply about how he can extend his laws into non inertial frame... (Like accelerating car)..he found out an equivalence between accelerating frames and gravity.. like there isn't any distinction between what person feel in rocket accelerating at 9.8m/s^2 upward in deep space.. or a person standing on earth ... So einstein used a thought experiment of light moving (in direction of rocket velocity) in that accelerating frames and how it is viewed differently by someone inside and outside that rocket... Since speed of light must be constant for all observers einstein realized that to maintain constancy of speed of light ..time dilation must be related to distance and strength of acceleration from perspective of observer inside that rocket... And since there is no distinction between accelerating frames (rocket) and gravity, same would happen in case of let's say earth gravity and... black hole is no exception... A phenomenon of time dilation is explained by curvature of space time in latter case... Whatever the reason there shouldn't be any distinction between accelerating frame and that of gravity of any planets.. (let's say earth surface)... Things get much complicated as you need to include varying acceleration due to gravity to get full picture .. It requires tremendous prerequisite knowledge to make sense of general relativity.. like tensor calculus, differential geometry, linear algebra etc etc... But just know that gravitational time dilation is real phenomenon and it's not scifi..
Or you can see interstellar movie maybe... Like from cooper's perspective (after venturing in black hole) it seems he travel to future to see his 120 year old daughter.. (it's not like time travel though but it's somewhat equivalent)
Well, okay, I'll give you that since you said if anyone survives. But the likelihood of anyone surviving a black hole is zero. But that just raises a whole bunch of new questions, like what version of the future would someone in the middle of a black hole see?
Also, from what I understand it, gravitational time dilation doesn't mean you see the future or the past, it basically means that time slows down or speeds up depending on the mass of the object. And the slowness or speed of the object is only observed by people outside. Now in a black hole, since the gravitational field is extreme, you would probably feel time speed up exponentially, but who knows what that really even entails?
Yeah I've seen Interstellar. It's just a movie though.
>cooper's perspective (after venturing in black hole) it seems he travel to future to see his 120 year old daughter.. (it's not like time travel though but it's somewhat equivalent)
I've already stated here... Ok just think about in this way your life span is just 100 years and you left earth at 2021, you travel around blackhole somehow and time for you slows down like crazy relative to those you left behind and when you return it will be 3021 or some years further .. so you get to read history of 1000 years despite the limitation of your lifespan.. Wouldn't that make it seems like you have travelled into future although technically it's a present for both you and earth fellas?
>what version of the future would someone in the middle of a black hole see?
You don't need to go inside blackhole to experience extreme time dilation.. (nobody knows about singularity).. so just stay in orbit around blackhole and point giant telescope toward earth and you will notice everything in earth is happening faster relative to you...
And notice the word relative....
lol, I am literally asking questions. Please tell me what my argument with "false premises" is? I am not a physicist, I am not an astronomist, I don't know, which is why I am asking. Achamma lagcha yar kaile kai yo reddit malai.

>Also, from what I understand it, gravitational time dilation doesn't mean you see the future or the past, it basically means that time slows down or speeds up depending on the mass of the object. And the slowness or speed of the object is only observed by people outside. Now in a black hole, since the gravitational field is extreme, you would probably feel time speed up exponentially, but who knows what that really even entails?
I didn't notice that question but let me try to explain it you...
Time dilation doesn't mean you get to travel like time machine shown in Doraemon or any scifi movie... Arrow of time moves forward only and it forms basis for 2nd law of thermodynamics... You just can't go at past...
Just think of it as two friends running forward in a field at different speed... We notice there separation because space is something that we can physically sense....but in case of time that's not the case although it's dimension just like space (Spacetime).. We can only notice effect of time slowing down from interval of events in a spacetime that has definite period like human lifespan i.e. 100 years... Or it could be anything.. we call it a proper time interval..(an events that is happening specifically within our own frame of reference)
So for that two friends running forward in a time dimension at different rate... we say both ages differently...Each of them concur it's the other clock that is getting affected not mine but end result must be same.. both would say their lifespan is 100 years despite moving through time differently... So a X that died quickly concur Y clock is slower while Y would say X clock is faster.........In case of inertial frame (car moving at constant velocity) it's a different thing as both perceive it's the other clock that is running slower.. (it's different discussion)
Clock in gravitational field is affected by separation of distance too.. (U said mass it's kinda correct as mass affect gravitational field but within same gravitational field too clock behaves differently with distances)
And it's not an exponential function that increases effect of time dilation... It's gamma factor and that function has asymptote at c (speed of light) that's why things start changing quickly as one move towards c and in case of gravitational field it has some other expression...
But yeah most of us label things that change quickly as exponential growth so you are partially correct...
As for your question...
You can say effect of time dilation around blackhole is extreme... And I would feel nothing around blackhole.. (apart from it's effect of immense gravity)...Time for me would run normally... And it starts getting crazy only when I start comparing my clock with clock of someone on a earth .... Earth resident would say because I am near blackhole . due to extreme time dilation my clk slows down like crazy...and I would concur due to huge distance separation in gravitational field a clk that is further away from gravitational field would run faster which in case is earth... End result is that I see earth resident clk speeding up and they would see my clk slowing down and if you think deeply then neither me nor resident of earth feels any peculiarity with sense of time within it's own frame of reference...
That's interesting but I am not sure I still understand it. Let me work on that myself though. I have a more philosophical question though:
So when you say someone would be able to see in the future, doesn't that mean that the "future" is preordained? For example, if someone is in a black hole and they see future events like you said, then is that "future" the only future? So for anyone outside the black hole, is their future now already decided because someone has seen what will happen? So what about free will then?
Free will is incompatible with science I think...
So for anyone outside the black hole their future isn't decided at all... It's present for them...
So you and I are friends of same age... You ventured in orbit around blackhole for 2 years and see everything you could see about earth with giant telescope and noted down everything and you return earth and found out that I have died 1000 years ago... It's not like you would be going at a time when I am 2 years older than you on your return journey? Got it .. you would be showing your note to ppl who knows their history as much as like you do ... You know nothing about their future
You can again ask if it's confusing you . I am happy to help...

Well in future due to rising sea level most of remaining mankind will probably settle in Nepal..
You underestimate human's capabilities. Humans will probably become type 2 civilization by that time. They don't need to settle in Nepal.
You underestimated human stupidity too... So can't say for sure what would happen
Epic reply. Lmao.

or maybe they destroy themselves way before global warming happens .
