    Where did the matter/energy for Big Bang come from? On that note, what is outside the border of the universe?

      And then where did they matter and energy come from for that universe. It’s turtles all the way down…

      This question actually doesn’t make sense, it’s kind of a paradox in the same way the question of what happened before the Big bang is also strange in the sense that the universe and reality didn’t exist in a form with causality in effect.

      So asking a “before” question in reference to “before” time even started is paradoxical in and of itself. Since “before” wasn’t even a concept in existence.

      Which is why scientists don’t really worry about anything “before” the Big bang.

      The Universe is expanding, rapidly from the big bang still. At some point, it will slow down, and then stop. Then begins a catastrophic cycle of collapse with massive black holes coalescing into one universe eating black hole that compresses every bit of matter into a single point of almost infinite density. At this point the black hole destabilizes, and all of the stored energy is released in one colossal explosion. A Big Bang of sorts.

      The Universe is an Ouroboros.

        Sometimes I think our universe is just an explosion in a big ass combustion engine.

        So everytime I drive a car I create and destroy countless universes just to get some nuggets. Worth it.

        At some point, it will slow down, and then stop

        All of the current scientific evidence disagrees with this. 1) There is a velocity such that you can go faster than gravity will be able to slow you down: escape velocity. So, it’s possible even without any new, weird physics. 2) The hubble constant shows that the universe isn’t slowing down, but the opposite: it’s accelerating. Physics doesn’t know why (see Dark Energy). It’s physically measurable that things farther away are accelerating even faster scaling with distance.

      Outside: there is a theory of other universes outside . Which would explain the increasing rate of expansion in place of dark energy
