Can something happen without anything else causing it?
This is a concept that has been discussed for a long time ; you are in good company contemplating this fundamental paradox.
It appears that every action is a reaction (or to use the more customary terminology, every action is an effect of some number of causes, and is in turn a cause for some number of effects).
However, it must either be the case that there was a first action, which would necessarily be an uncaused effect, or that time is either a loop or is infinite in extent, such that there is no beginning and thus no need for an uncaused effect.
And none of those possibilities is really intellectually satisfying, so it’s an open question (which doesn’t stop people from insisting on the nominal truth of one or another of them).
And even with the loop or eternal universe, you can ask where it came from. Like why is it there, and not nothing?
Thanks for putting so much effort in your answer. If you think about it, it’s kinda scuffed and you either end with existence is not possible or there was an action that was not caused by one. Just like you said.
This is the kind of paradox that leads us (I mean humans more generally) to look for some fundamental assumption we’re making about time that will turn out to be wrong. I assume that’s true although I wonder whether it’s literally impossible for us to even imagine how time “truly” works, let alone measure it.
That strongly depends on your reference frame. As in, what system are you looking at? Where are you drawing your box? If your box is around the entire universe, then yes, every action is a reaction stemming from the big bang, with very few notable exceptions pertaining to black holes that I wont go into.
However, if your reference frame is a hand and a ball, then the hand pushing the ball is an original action, the ball moving its reaction.
What if the ball was talking shit?
Or if the ball was thrown at them…
What do you mean about the black holes?
It’s also worth noting, I think, that the universe might be spatially infinite, which makes “box” a funny way of saying it.
Well, its kind of a matter of debate really on the black holes, and its in regard to the law of conservation of information. I’ll freely admit, we are getting to the edge of my understanding here, but essentially black holes very nature of being inescapable by anything means that information, once inside, is permanently lost.
The reason hawking radiation was such a big deal is that it found a way for this information to potentially be released into the universe once again. That radiation is actually a pair of “virtual particles” (which aren’t real particles, more a mathematical trick to describe complex interactions between different fields and their particles). One of the particles “pops in” to existence on the inside of the event horizon and one on the outside, thus separating the pair. One falls in, one escapes. But since they didn’t annihilate the energy that the now real particle has must come from the black hole, hence, the energy has escaped the black hole.
Now, is that “action” a reaction, or is it a brand new action with no inciting incident? I dont have an answer, and its up to speculation because hawking radiation may or may not even exist. But its our best guess.
I mean, action and reaction aren’t rigorously defined concepts. When a nucleus spontaneously decays, you could just as well say that’s an action with no reaction by that measure, but it happens all over the place. Vacuum polarisation from an electromagnetic field is even closer.
While I would agree, both of those are theoretical - just like my example. The truth is we haven’t, and can’t, test these things and see their mechanisms take place because of their timescales. But it is a really fun thought experiment
The hand was guided by neurological impulse
Not if your chosen reference frame is a hand and a ball, as per the example
I mean aren’t you saying: “Something can happen without a cause if we just ignore the cause.”
I read ops question as about reality, not hypothetical universes that contain a hand that moves a without an arm or brain attached.
This isn’t the Addams Family.
I get the confusion, but a reference frame is a very important limitation for calculating what you need. Its not about whether the arm exists behind the hand, but whether its effects are important for the calculation.
For the sake of the hand pushing the ball, its not. Only the momentum of the hand and the inertia of the ball are important.
I understand very well, and also understand anyone with the capacity will understand the frame of reference doesn’t explain the phenomenon. It’s how we went from four corners to heliocentrism to galaxy, universe, and multiverse.
Don’t leave us hanging! Go into it!
In physics, we can’t really consider the universe to be deterministic at the quantum scale. We only think it must be when we try to look at particle interactions as a scaled down billards game.
Only the second time is a re-action.
Why did the first thing happen on its own though?
What prompted you to ask this question? 🤔

I’m imagining a middle school student answering a homework question about Newton’s laws, and people are responding with, “Well what’s your reference frame? Consider Virtual Particles in Quantum Theory.”
Even the standard formulation of newtonian dynamics admits nondeterminism. (This requires a non-Lipschitz setup to work; and in any case it doesn’t describe the world we live in. Also it’s a mathematical description, not the real thing.)

And https://en.wikipedia.org/wiki/Quantum_fluctuation
Edit: I guess it’s these two are kind-of the same thing
Though those aren’t really proven real: From that same Wikipedia article:
Although widely used, they are by no means a necessary feature of QFT, but rather are mathematical conveniences — as demonstrated by lattice field theory, which avoids using the concept altogether.[citation needed]
Getting back the the top question, if everything is a result of something, what started it all?
Kind of, but not really, those are caused by the universe existing, but yeah, you can’t get closer than that.
Are we looking at the physical universe, or are looking at psychology, or philosophy contexts?
All of them
Yes and maybe not then. Look at Newton’s law, even it deals with psychology if not physical action and realize that we (under some theories) have free will to make the actions that will cause those. So something will happen to make you (or someone else) do an action and even if you (or they) don’t like it it happened. You can look at it from 1000 angles but either way someone with that personality would make it happen that way.
So gotta just accept, it is what it is, try and make it better and I hope it works out. Mean unless you can see the future and change things, we all are who we are, may. It be worth knowing or hanging out with but somebody probably made something you don’t want to happen, happen. C’est la vie.

I’ll try to bridge science, philosophy and spirituality, as I usually do. To me, there aren’t clear boundaries between them bc, to me, they’re highly complementary: Science offers the skeptical-empirical rigor and materiality, Philosophy offers the paradoxical questioning and Spirituality emerges from subjectively perceiving the previous two.
I start with the hypothesis that the universe always existed. In such a case, the Big Bang isn’t the beginning: rather, it’d be some kind of cyclical cosmic phenomenon where matter and/or the fabric of spacetime continuum collapse (due to expansion) only to explode and expand again. This would respect the Laws of Thermodynamics (and Lavoisier Principle) because there’s no energy nor mass being created nor destroyed, just transformed, endlessly. Big Crunch deserves mention bc it’s exactly what it’s about.
There’s also the controversial theory of Zero-sum, where the universe doesn’t actually exist. It may sound crazy (We are existent… or are we? Vsauce song starts playing), but it would also respect the aforementioned laws: there’s no need of creation or destruction if the overall sum of everything equals to a round nought.
We could also mention the Multiverse theory, String (M-Theory), and Big Bounce. In such a scenario, this universe is just one of countless universes, so the factor sparking it into existence would be outside it, thus outside (beyond) space and time.
The latter takes us into philosophy, the Aristotle’s Prime Mover. It could be seen as the “thing” beyond this universe, except that it isn’t a “thing” because it has no “thingness”, but this lack of “thingness” would imply non-existence, except that it’s not something nonexistent either. Here is where human language struggles to define it: language requires “thingness” and temporality, yet the Prime Mover has neither (and it isn’t an “it” so it could “have”).
This takes us to spirituality. Many religions oversimplify this as “creator deity(ies)”, and many (if not all) religions tend to give it agency and shape. While I do have some religiosity (Luciferianism) and tendency of personification (e.g. Lilith as both a red-haired woman and an owl), I also hold the belief that cosmic forces have no particular form, it’s just me trying to give some Order to Chaos… And that’s what the whole existence seems to be about: Ordo ab Chao, a cosmic, eternal tug-of-war where it’s guaranteed that the “sparks” of cosmic order will eventually decay back to a soup of primordial chaos, only to the very chaotic nature of this soup to emerge order again. It’s akin to a Double Pendulum, where sometimes the apparent rhythmic motion vanishes into chaotic motion just for the rhythm to unexpectedly reappear later, but it’s just the Cosmos: endless and uncaring about lifeforms, for life is just stardust.
I could explain more, but I’m limited to 3000 chars so I must end: Cosmos always existed and never existed.
Good text 👍 Faster to read through than it looks. The result probably is that we just don’t exist 🙂
The only candidate for that ever being observed is the collapse of quantum wavefunctions, and there’s interpretations where that’s not really random either. Everything else we’ve ever measured is definitely totally deterministic.
What happened right before spacetime?!
Spacejam.
MJ dunked us into existence? Unorthodox belief!
What is the salient meaning to something that has literally no connection with the past? Wouldn’t that be tantamount to a “proof of god” situation just expressed in different terms?
🤷
I am sitting still. Now I am reaching for garlic bread. Nothing acted upon me to prompt that. I am eating the garlic bread. Am I defying the very laws of physics? Yum yum.
The presence of delicious garlic bread prompted you to reach for it.
The network of neurons that has evolved to have specific taste preferences that allow us to eat food that isn’t bad for us caused him to eat it. The planning done by said network is what caused the bread to be there in the first place. We all know that we have to eat, and tend to be good at ensuring that we can eat whenever we feel like it.
It’s all pure physics and chemistry. When your stomach gets empty you feel hunger due to the stomach or related glands releasing mRNA that causes the brain to activate different circuits that cause you to seek food. Animals that don’t do this don’t live for very long.
