    Ex physicist here: Fucking no clue, but here’s two neat ideas

    1. Because there has always been things. Basically it’s entirely possible the universe just kind loops around given enough time, there are a few really interesting ways to do this but the classic one is where the big bang reverses and there’s a bug crunch before a new big bang. That’s not very likely based on our observations, but there are other more mathematically complex ways to have a cyclical universe, and they don’t necessarily require having a defined beginning.

    2. Because nothingness is unstable. Basically, if there’s a concept of nothingness, no energy, particles time or space, but it’s possible for little universes to occasionally exist and disappear really quickly, then it’s possible that our universe suddenly popped into existence, got really fucking big before it could disappear again and then got stuck existing. This is based on the highly advanced area of physics called making a wild fucking guess.

    I’d say most likely that we’ll have to be satisfied with that not being a question that can be answered. Much in the same way that we can’t answer the question of why the laws of physics look the way they do, we can just describe what they currently are.

      None of that actually answers the question because it’s a philosophical one and not scientific. This really irritates the scientific mind.

        Yeah that’s what I was getting at, all we can do is guess. It’s pretty easy to realise it’s impossible to answer scientifically, anything that could have any impact on our universe must necessarily be part of it and so cannot tell us anything about what came before.

      There’s a third option: Black holes create new universes through some as yet undiscovered process. Then your existence just becomes a statistical eventuality, as do every other life that you could ever live.

        There’s a fourth option: every reference to the mystical properties of black holes on lemmy creates new universes through some as yet undiscovered process. Then your existence just becomes a statistical eventuality, as do every other life that you could ever live.

    No one knows. I really want to know, but the current understanding takes us back only to the big bang. Not why it happened or why anything exists at all.

    The Anthropic Principle is at work here. If nothing existed we wouldn’t be here to ask why it exists.

      Here’s some reaching: There’s the theory hypothesis that our universe is the inside of some construct in a higher universe* that is similar to if not actually a black hole.

      In our universe, time and space inside a black hole are causally disconnected from the outside so there can be a defined beginning without there needing to be time continuity across the event horizon. It’s often said that time and space switch places inside a black hole, which could mean that our time is relative to space outside of the universe. This hurts my head to think about. Almost like our time dimension runs sideways relative to whatever was “before”.

      * As to whether this is turtles all the way down / universes all the way up, we’ll probably never know.

    The universe feels like a pretty whimsical place, so why not? Might as well try it out. If it sucks, you can always let everything crash into a singularity and start over.

      Beat me to it. Why not was my answer to this question too.

    The worst part is we’re here now and most of us are intrinsically forced to deal with whether we want to or not.

    Because, to maintain “nothingness” the omniverse must balance matter and anti-matter.

    Well, that became unbalanced because of random fluctuations.

    So theres a pocket of matter and anti-matter didn’t annihilate for some reason, I call it “plot armor” reasons, and that separated from each other forming 2 regions of space.

    So the region of positive-matter, through randomness eventually formed our universe.

    The region of anti-matter probably formed its own anti-verse

    Ok I’m bullshitting, I’m not a scientist and I made up the whole thing mmkay? That’s my amateur explaination of the universe. Fight me.

    But like, philosophically make sense.

    How do you get something from 0?

    0= [+1] + [-1]

    See? That’s my mathematical proof.

    Its my version of E=MC², but with the creation of the universe and anti-verse.
