You do realize that asking questions is the only way to correct those total misunderstandings? ;)

I haven't read as many books as I want to. I used to read more. But the focus to do that is no longer available to me.

Nah, I haven't.

I just like how Dragonball Z handles time travel.

it seems like lately every post i see from this sub is just some person asking a question based on total misunderstanding of some fundamental thing. same reason i unsubbed from eli5. and pretty much why i'm gonna unsub from this one right now. so long!

have you read the book 'pathfinder'? and it's sequels. it goes all crazy with this exact kind of scenario. it's by orson scott card. it does have the annoying parts of his writing style tho.

Hi! Could you please tell me where are you situated? I love star gazing and have taken few trips to dark sky parks. Honestly the only place wheres I found like complete darkness were creator lake NP in Oregon and big bend NP Texas. Most hyped in my opinion was Death Valley NP, it had so much light pollution from Los Vegas and Los Angles skylights. No matter where I went, there would be no complete darkness. People take photo and edit them to make them appear all beautiful but in reality the place would be sh!t lit from light pollution from nearby cities.

He looks good for someone who floated alone in space for 20 years.

What you're saying doesn't make much sense but it sounds like you're very trying to describe the Novikov self-consistency principle. To be clear, this is a conjecture with no scientific basis. Time travel to the past is theoretically not impossible in certain spacetime geometries but that doesn't mean it actually is possible, and even if it is, we certainly don't know how to do it, so we have no way of saying how something that might not even be possible might potentially work if it were possible.

I like the version where instead of altering the future when you go to the past and alter things, you snap off an entirely new independent timeline. AKA Nothing you do will affect the timeline you came from when you hit the "Return to Point of Origin" button. AKA Dragonball Z time travel.

You can totally go one day backwards and kill the past day version of your own self and you will continue living because you clearly did not die in your timeline, yet. Then you could go another day further back and grab you from the past and bring yourself to the future. Multiple you would be fine because, although you were never recruited by yourself, you gained the ability to recruit yourself later.

Splitting timelines might make some of them collapse, dunno if it's possible in the first place, but I like this version for storytelling.

You can have your cake AND eat it. But you can never change mistakes from your own time, you have to live in an always-moving-forward way.

I read the study. It's from the same uni I did my Masters in Astrophysics at.

It was a purely mathematical hypothesis paper.
There is no evidence of close time curves being any more real than multiversal theory. The publication is a mathematical approach to if Einstein-Rosen Bridges actually exist within the physical world.

If a CTC is physically proven to exist, then yes, this study has some merit. But as far as current human knowledge goes, this is on the same wavelength as string theory, multiverse theory, or the death of the universe.

At the end it says “A recent study at the University of Queensland may have the answer to this baffling paradox. In this study, the researchers prove mathematically that paradox-free time travel is possible, showing that the universe will self-correct to avoid inconsistencies.”

Three keys to seeing Andromeda: clear dark sky; giving your eyes at least 15 minutes in darkness to develop your "night vision"; and using "averted vision", i.e., not looking directly at it. If done correctly it's surprisingly obvious.

You aren't making a lot of sense with your question but the link you posted above refers simply to special relativity

But you'll want into what we astrophysicists call "light cones" or "null cones". This will help point you in the direction that UQ student went with his study on chaos-free time travel. This study also assumes closed time curves, which is still just a hypothesis at this point

That doesn't make sense. Why would he just use the photo? Are you ok?

This isn’t exactly what I was looking for but it references what I’m talking about

I believe the phrase you're looking for is 'wishful thinking'.

True! Inverse square law can help us out here.

Just punched the numbers in, 26 dB louder if you were located 80 meters away from the rocket, or roughly 162 dB. So yeah, 136 dB from 1.6 km would make total sense.

thanks man, and yes you are ☺️. we are eternal.

I feel the same way but could never express it so eloquently. I am God.

Space is everything. Space is our home. Our universe is our home. Our universe made us and is us. Our consciousness is a gift, it’s a byproduct of the universe. Its the universe awakening through itself. And if you think you’re smart, then how smart is the universe that made you? I would guess infinitely smarter. I believe there exists an intelligence that’s beyond our capabilities of understanding. An intelligence that can’t be put into words because we are only human. But i believe in its own way, space is alive. Space is the God. And yet we worry about trivial mundane things in our everyday lives all the while we exist in a seemingly infinite space. Its amazing. But never forget, we are one with it, and when we die, I believe we return back into it and become truly one with it again. We are space and we are all one.
