I recently thought of the idea that when we die, we just get to start our entire life over from day one. But it's not always destined to end the same way and we could change the outcome of things.

Déjà vu could just be overlapping memories from your previous experience in the same situation.

If that were the case, I would be perfectly satisfied with it.

You almost immediately jumped to the conclusion that there's no afterlife without any evidence for or against it.

People do this because they don't want to get into the religious/theological implications usually associated with the notion of life after death.

I sometimes find it odd that the universe exists and yet doesn't exist. I also find it interesting that everything ALMOST fits into a nice category but never does completely. I wonder how randomness is possible. I also think that it's odd that science is ultimately an opinion reinforced by itself. I wonder if humans are the macro version of neurons. I think about how causality has no pause button.

[Anonymous No.2721109]

The idea of us being molecules with no soul seems pretty illogical to me, which is why I don't believe it. Molecules don't think, feel, and have emotions or a personality.

If that were true, we'd likely just be shambling creatures that talk in grunts and only operate on instinct.

Deja vu is just different neurons firing the same signal into your frontal lobe but one or more of those have a a millisecond delay and so it seems like you know that thing but you can't remember when. This is because it is not stored as a memory but as short term data. Think of it as what RAM is to a hard drive.

[Anonymous No.2721128]

thats exactly what we are. Just a bit more complicated, and our instincts more evolved, only to give us a mere illusion of choice.

Again, not to get into religion, but most religious people will tell you that animals don't have souls, only man.

But really, higher animals seem to have feelings, personalities, and emotions too. Their logic and thinking skills are very simple compared to man, though.

[Anonymous No.2721163]

>>2721109
>Molecules don't think, feel, and have emotions or a personality.
You underestimate how the brain works, and how complex it is. Many animals do what you described as souless, the only difference between them and us, is that we have a neocortex and most of them don't. Neocortex is a development of mammals, and you might be aware that dolphins/gorillas/elephants/etc have been shown to have certain degrees of consciousness and thought.

We have built computers that can calculate the most unbelievable things around the concept of logic and binary, is it so hard to think we are just more evolved, incredibly complex, organic computers?

Well, don't mind me, if we live long enough we might see the breakthrough in artificial intelligence, if someone ever reverse engineers a brain to a decent degree.

[Anonymous No.2721183]

Conciousness may not be molecular in nature. We might have to look deeper, at a quantum level, to discover how it really works.

Just recently it was discovered and confirmed that the photosynthetic systems of some protists and bacteria actually make use of the quantum entangling effect to produce higher yields.

This means that there are likely millions of biological systems that make use of quantum physics effects, and our brain might be one.

Nothing definitive has been published yet, so I'm not saying this is the case. It's definitely a possibility though.

[Anonymous No.2721184]

>>2721163

Recent research suggests that the brain is even more complex that we'd imagined before. No man-made computer could conceivably come within a fraction of the brain's complexity.

Not even this computer.

I have heard mucho-many stories of encounters and sightings of ghosts. Before you tell me to go back to /x, I should point out that it's impossible to totally rule out the existence of an afterlife due to that.

It's my opinion that if ghosts/spirits exist, they constitute some higher form of energy that is not directly measurable with present scientific techniques.

FWIW, the Buddhist view of reincarnation is that your energy is simply transferred to another living thing when you die. It's not a literal "soul moves from body A to body B" thing, especially since Eastern religions don't have the same concept of the soul as Western religions.

>higher form of energy
What does that even mean?
This is a science board, try to not use coffee shop terms.
If you have a conjecture about some energy thing, describe it regarding the standard model of physics (which has already been proven true many times, and might get the final step at LHC).
You can even make shit up about neutrinos traveling in the 4th dimension, but don't be vague.

The fragile nature of life. Even if trans-humanist immortality becomes reality, there is still the potential for accidental death. No matter how secure you think you are, forever vigilant you must remain. For once life ends, it never begins anew.

It might be hallucinations, it might not be. We don't know.

I honestly don't think people would have as much of a problem with the idea of ghosts or an afterlife if it didn't carry religious implications. It's hard to discuss that sort of thing without bringing up the G word, and so we tend to shy away from it.

Anyone ever hear the old joke about the heart and brain debating which was the most significant part of the lifetime in the body, then the rectum got tired of hearing both of their arrogant opinions and decided to clamp shut?
Well after about four days the heart found it was getting to hard to pump, and the brain became to weak to function and the body died.

The fact that we could have a new consciousness with all the same behavior and memories of the old one and not tell the difference. I first thought about this when people talked about moving matter by the molecules then putting it back together (sci-fi teletransportation). Would we be the same man? Or would we have died and a new identical man be there? Then I realized going to sleep present the same scenario.
It's pretty stupid, but it troubles me.

Thinking about what existence is.
If I think about it too much I'll start tripping and that usually keeps me from sleeping.

Also, consciousness, and thinking other big things, mainly about the universe and what it all means (how it means nothing) and how beautiful the universe is for being something "random".

All of those things. Thinking about the universe and other possible dimensions and how amazing it is that something exists and how happy I am that I get to experience it.

Wondering what happens to me when I die, or thinking about my body being broken down and given back to the universe.

... Oh, this one is fun, thinking about how, when I die, I will be instantaneously reborn to live this exact life over again.

All kinds of shit.
