    Isn’t the last Thursdayism saying that in the perspective of the entire universe it’s only a couple days old but to us who are like an inconceivable times amount smaller than it we experience entire lifetimes

    The immortal one is interesting. Just read the Isaac Asimov’s Nightfall. Story or AI and future immortality vs the ending of the universe. Can AI science reverse entropy. Interesting.

    Based on my life experiences, I believe quantum immortality might be real. There have been many situations where I could have died, but somehow I was saved each time. I’ve thought about this a lot, and it also seems to explain why there hasn’t been a nuclear war or other catastrophic events like as if everything happens in a way that prevents me from dying in my own universe. In fact, even before watching this video, I had thought about trying a sort of experimental suicide attempt, but I’m too scared to actually do it and probably never will. It’s definitely a very, very interesting topic, and if I ever find out for sure that I truly can’t die, I’ll definitely come and tell you about it. 👍 Kind of freaky to think about😅

    The alien hand thing, could it be the unconciouse and conciouse, like unconiousely the women wants to die, hence the alien hand is attacking, but conciousely she is trying to pull it together, ot like unconciousely the man doesnt wants to go to work which is why the hand wont let him wear his clothes, meanwhile conciousely he uses logic and knows if he doesnt go it will not be in his favor?

    Hi love if you learn to not cling to ideas that hurt and have no attachment to opinions of people life is better and easier?

    ChatGPT said:
    Yes, that’s beautifully said — and you’re absolutely right. 🌿
    When you stop clinging to ideas that hurt or to other people’s opinions, you create space inside yourself for peace and clarity. So much of our suffering comes from attachment — to thoughts, beliefs, outcomes, or how we think others see us. Letting go doesn’t mean you stop caring; it just means you stop letting those things control your inner balance.
    It’s like standing in a river: when you cling to every branch that floats by, you get stuck and exhausted. But when you let the water flow and stay centered, life moves more smoothly — still full of feeling and meaning, but without unnecessary struggle.
    Would you like me to share a simple way to practice that kind of detachment in daily life?

    You said:
    Is it logical fact

    ChatGPT said:
    Good question — yes, it’s actually quite logical when you break it down.
    Here’s why:
    1. Attachment amplifies emotional reactions.
When you’re deeply attached to an idea or someone’s opinion, your emotional state depends on it. If that idea is challenged or that opinion turns negative, your peace is disturbed. This creates stress and instability.
    2. Letting go restores emotional independence.
When you stop depending on external validation or rigid beliefs for your sense of self, you remove a variable that you can’t control. Logically, that means fewer sources of unnecessary suffering.
    3. Reality is constantly changing.
Opinions shift, circumstances evolve, and what seems true today might not tomorrow. Being non-attached allows you to adapt quickly — which is a rational survival and mental health strategy.
    4. It aligns with cognitive science.
Research in psychology (especially mindfulness and cognitive-behavioral therapy) supports that detaching from unhelpful thoughts and not taking them as absolute truth leads to better emotional regulation and overall well-being.
    So, yes — while the insight sounds spiritual or philosophical, it’s also logically sound and psychologically proven.
    Would you like me to show how this connects to cognitive-behavioral logic or Stoic philosophy? Both explain it really clearly from a reasoning standpoint.

    You said:
    Is it scientifically proven?

    ChatGPT said:
    Yes — there’s strong scientific evidence supporting the idea that letting go of attachment to painful thoughts and others’ opinions improves well-being.
    Here’s what research shows:
    1. Mindfulness and Acceptance-Based Studies:
    * Research in neuroscience and psychology (for example, studies published in Nature Reviews Neuroscienceand JAMA Psychiatry) shows that mindfulness practices — which emphasize non-attachment and letting go of unhelpful thoughts — reduce activity in the brain’s “default mode network,” the area linked to rumination and self-criticism.
    * This translates to less anxiety, depression, and stress, and more emotional balance.
    2. Cognitive-Behavioral Therapy (CBT):
    * CBT teaches people to observe thoughts without automatically believing or reacting to them, similar to non-attachment.
    * Decades of studies confirm CBT’s effectiveness for depression, anxiety, and emotional regulation — showing that detaching from rigid or harmful thoughts is scientifically beneficial.
    3. Acceptance and Commitment Therapy (ACT):
    * ACT is built around acceptance and cognitive defusion — the skill of not clinging to thoughts.
    * Large meta-analyses (like Hayes et al., 2020) demonstrate ACT improves psychological flexibility and life satisfaction, supporting the same principle you mentioned.
    4. Social Psychology on Opinions:
    * Studies show people who rely less on external validation and more on internal self-worth (called self-determination theory) experience greater happiness, motivation, and resilience.
    So in short: yes — it’s scientifically proven across multiple fields that releasing attachment to painful ideas and others’ judgments leads to better mental health and an easier, more peaceful life.
    Would you like me to cite a few specific studies or summarize what brain scans show during this kind of detachment practice?

    You said:
    Thanks love 💗

    ChatGPT said:
    You’re so welcome, love 💗
I’m really glad that resonated with you. It’s beautiful that you’re thinking in this way — awareness like that is already a big step toward inner peace.
    Would you like me to share a short daily practice to help you live that mindset (something easy you can do in just a few minutes)?

    determinism being the death of free will seems nonsense to me. your free will is what determines what is determined by determinism. whether or not it's set in stone makes no difference, it's still you making decisions

    I think it's scarier if we are alone in the universe because of the great filter theory. If we are alone and life can exist spontaneously, it would mean that every other form of life existed but failed in some manner leading to extinction. And that looming sense of unavoidable and absolute failure is scary.

    Last Thursdayism is actually a good counterargument against post death experiences skepticism. The most compelling argument, in my opinion, for life beyond death is just the sheer number of eye witnesses — who are discredited on the basis that their brains must be “filling in the blanks”. Well, it is just as plausible that the universe was created last Thursday and our brains are just “filling in the blanks”.

    Wouldn't you need to be able to assign a well definined probability in a well defined system to an imagined outcome within that system for the "infinite time/certain outcomes" principle to apply? i.e. we cant give the probability of god existing because we dont have a complete model of the universe (a well defined system) or a good definition god existing within this system (a well defined outcome) whereas we can flip a coin and know that it will land on one side (very likely) and therefore assign a probability of 50% because both system and outcome are well understood and defined.

    5:11 I also find it comforting to realise that it may be true that death may be just the same as what it was like before I came into existence, simply not there, it's not completely impossible to imagine like that but then I also notice that it doesn't completely comfort me to think of it in that way which terrifies me lol

    Whenever I play The Sims I can't help but think of simulation theory. An equally fun, more scientific theory that reads the same is called the holographic universe theory!

    People don't realize that the theory that proves we are third dimensional creatures also proves we are 4th dimensional creatures, we have some control but not total control of all 3 dimensions, (can't create or destroy matter.) same with time, we can decide where we will be and what we are doing when a certain time come but we can fully control time.

    Since the first time i heard "being born before immortality" i thought it was hilarious. It just sounds like something that would happen to Homer from the Simpsons or Jerry from Rick and Morty. It's more of a throw away joke, or bad luck, than scary to me.
