what happened before the big bang? please

>>16716854 (OP)
Everything was an incomprehensibly dense singularity. There was no time so “before” didn’t exist as a concept.

>>16716857
Singularities only arise in general relativity, which is not quantum mechanical. We know that quantum mechanics "smears out" singularities (via distributions or just plainly forbids them due to existence of ground states), so a working theory of quantum gravity is expected to be free of singular behavior.

So the actual answer is: we don't know because we don't have a working quantum gravity theory.

>>16716884
quantum is the key?

>>16716892
It's not like it's the "key". Quantum mechanics reduces to classical mechanics (in the sense of "non-quantum mechanics) in the limit that the Planck constant goes to zero. No converse relationship holds: you cannot "derive" a unique quantum mechanical theory given a classical one. So it's a one-way street. If you want to truly understand gravity and how it interacts with matter, you need a quantum theory of gravity. All attempts at quantum gravity have hit a theoretical roadblock and any experimental evidence would require ridiculous stuff like sending a probe near a black hole or building a collider the size of our galaxy.

Another universe > black hole > stuff traverses to "singularity" or Einstein Rosen bridge > into white hole (we are here)

We are inside a white hole, the singularity only exists in our past and we can only move away from it (time reversal of the inside of a black hole) therefore everything is moving away from and expanding from the singularity. Eg time has an arrow of direction - it only moves away from the singularity

The boundary of the universe is the inside of the event horizon, which stuff can cross over out of, but nothing, not even light can make it back inside > the absolute visibility limit, you cannot see past this even if you were close enough to it, though we can't catch up to it

Technically speaking the universe could gain mass this way from the event horizon, via time reversal hawking radiation. Outside the event horizon of a black hole particle pairs positive and negative form and more negative particles fall into the black hole and annihilate with positive particles, causing a black hole to evaporate over time if it doesn't take in enough mass

In a white hole it's time reversed, particle pairs form on the inside of the event horizon (reversal of combining), and more negative than positive particles cross the event horizon and exit the black hole, building up more mass as the universe expands potentially

There's also a model of black holes that solves both observable violation of energy and the information paradox at once and can be extended to explain dark matter. Hawking radiation reduces the black hole mass until the event horizon shrinks to the point where the remaining mass isn't enough to be a black hole. Keyword remaining mass. The event horizon is gone, sealed off. The mass is trapped 'inside' the former black hole. It is topologically sealed off and inaccessible from our universe a pocket of mass or baby universe that is there but causally disconnected, no paths in spacetime can take you there. It's mass may still gravitational affect spacetime. There is "nothing" physically observable there, but there is an effect on spacetime.

There are now bunch of semiclassical singularity theorems, so there is a good chance singularities will be not be fully resolved in quantum gravity, specially if the GSL and Bousso bound hold.

Well, it’s just semiclassical. The gravitational field is still classical in the semiclassical approximation and singularities pop out because of gravity, not necessarily matter. For example, they still exist in the vacuum solutions.

IN THE BEGINNING, packing problemed every single base plank level, cube shaped, magnetized, RGB, Plank bucky cube into as tight of shape as they can form magnetically leaving no empty spaces that can be moved into without a force to cause the cubes to separate magnetically.

If no cube has any empty locations, free from other cubes, that it can move into, and is magnetically locked together into a singular magnetic object/structure without any gaps at all, and is unable to detach and break off, then there exists no time.
Time in our universe is the movement of 1 magnetized, RGB, base Plank length cube into 1 empty cube location, Front/Back, Left/Right, Up/Down, and the ratios thereof (much like a blackhole, the Universes parts, broken down to base Plank sized cubes, packed together as tightly as possible leaving no empty cube spaces, no time = no movement).

So, in order to get to the point where we can actually separate the singularity blocks magnetically from one another, we have to create our circle in essence, or close our loop.
We connect the end of the build, to the beginning through a circuit.
So the build itself is connected to itself from the beginning solid blocks, to the end of the universes built block arrangement, but also from the end of the build, then back to the beginning separately.
Creating our circuit.
The past then affects the future, and the future affects the past.

The wave function collapse, in essence.

CCC is not a big crunch, once everything decays into photons and is equally equidistant that infinitely large diffuse cold cloud of photons becomes the primordial seed of the next big bang (information is scale invariant ie angles matter scale doesn't so the infinitely tiny hot and dense spec that starts a big bang is the same as the infinitely large diffuse and cold end of one)

>>16718494
ie what comes after the big bang? the next big bang. The previous big bangs heat death state could fit into a space smaller than an atom in ours galaxies and all.

BB is just one side of a theory which has two plausible possibilities, there is an alternative that hardly gets mentioned. The Big Shrink.
Mathematically there is absolutely no difference between a Universe where the matter remains constant and space is expanding, and a Universe where space remains constant but the matter is shrinking.
Go on, ask any competent physicist or mathematician and they will confirm this. If matter is shrinking there would be absolutely no difference between what we see in the Universe today and what is postulated by the BB alternative.
So its equally possible that the Universe did not start with a singularity but rather began as fixed volume of space ( perhaps even infinite ) and other than local gravity interactions all the matter within it has been shrinking in on itself ever since, and will presumably continue to do so.

This is the absolute lowit hand wave that retards like to throw out. Something they heard some other monkey say, and they feel smart repeating it like a parrot. Unaware that they have demonstrated their lack of intelligence.

If the universe is building large and small fractal like structures, atoms and galaxies, elements, star systems, local groups, than that leads us to believe that if the universe were to collapse back again, the speed would be slowed down and absorbed due to the porous sponge like structure now formed, creating a gravitational net.

That is to say the universe is expanding outwards (magnetic field of the total combination of Pi and the shapes formed) because it needs a place to put the dirt it is proverbially digging out of the ground, so to speak.
I.E. gutting the solid singularity at the start, and building complex pieces from it, and then bringing those pieces back in to fill in the holes we dug out.

The closer atoms are together, the faster the photons (information/data) are exchanged between the electron shell layer jumps.
The machine calculates faster, the closer the assembled parts are together. The less distance that photons have to travel in between electrons, the faster the processing occurs.
And the more complex a single part, a single atom, the more electrons in a single atom, the more photonic data it can exchange faster. Like cute lil mini neurons.

What do you think it is building? And will we have a say? Are we an error, a part of, or the intention?
Why build such cool slop, if you have no one to show it to and dab on? And maybe eventually teach?

>>16718521
There's a boundary or "edge" to the universe, beyond what you call the visible universe, we are completely surrounded by an event horizon. We move away in time from the singularity known as the big bang. The event horizon which you cannot access by conventional means would take you either to big bang, or additional space, you can enter that horizon/exit this universe but not return, where the additional space is cascading universes like a series of waterfalls

>>16718508
that would at least make some sense

>>16718563
I genuinely think that quantum physics for the last 30-40 years has mostly been full of shit. There's been so many theories that are made without evidence and scrapped.
Black holes are a particular example of this. There were so many theories about how they're inescapable but hawking radiation throws most of that out the window.

>>16718575
I don't know much about the topic to begin with, but I would assume they observed some shit via telescopes and measuring, and they were trying to build theories that would rationalize those weird as fuck measurements and behaviors, thus leading to completely strange theories

Here's the sticking point. The Universe is fundamentally simple. We on the other hand have invented a cacophony of particles, equations, and theories to explain phenomena which is currently beyond out conceptual grasp.
We have monkey brains and eyes not far evolved from those of fish. Our conceptual understanding of reality is severely curtailed by the limitations of our present cognitive abilities. It is a supreme conceit to think otherwise. You could imagine some sentient ants inventing various ideas to explain the impact of human's industrial pollution upon their colonies but without having the knowledge or intelligence to conceptualize chemical interactions on the atomic scale. Their ideas would be laughably wrong. That is us. So you may as well just give up trying to understand anything and smoke lots of weed while enjoying mind blowing anal sex with hot trannies.
