This is wrong. if you consider entropy then you will see that this is impossible given that our universe started with incredibly low entropy

How do you know this universe "started"? How do you know this is not universe #238400716512 in an endless succession of big bangs and dying universes....which is literally "eternal"?

Examining and finding that the universe expands and therefore MUST have started at one point at some time does NOT mean that it must be an exclusive event. In other words: If there was a BB, there may as well be infinite ones. (Or universes born from "another dimension" into a BB and then dying towards/into another "dimension" where it in-turn may create another, new universe etc..etc...)

The universe was not created from nothing. It started from a point infinitely dense which exploded for an unknown reason.

It you want to blow your mind, consider that 49% of the matter created in the big bang was antimatter, and 51% was matter. Most of it annihilated each other, and everything you see today is made from that leftover 1%.

The universe actually owes its existence to imperfection. For as much as we use statistics to predict the predictable, understanding the mechanism behind imperfection is probably the most important secret to unlock. Why was it 51/49? It should have been 50/50 going by the laws we currently exist within.

If there were a singular explosion, all molecules resulting from that explosion would be equidistant and gravity would keep them locked in an equidistant lattice all pulling on each other equally. You need some kind of imperfection and all of a sudden things start twirling around and smashing into each other into exactly the way matter coalesced into the galaxies we have today.

What was the name of the sun that created our sun our planet? Has anyone named it?

All I want to know is if I'm traveling in a ship at light speed and turn on the headlights what happens?

My take is that it came from a universe that collapsed before it or perhaps a black hole from another universe. This could be something that has always happened and will continue to happen after our universe has ended. I don't believe that this universe is the only universe.

Collisions in a higher domain caused the big bang and instantiation of our universe in a lower domain? Either natural phenomenon or someone in the higher domain is playing with particle accelerator collisions and is creating big bangs and universes without knowing it.

Whatever happened we will never know because our physics and detection instruments are built from this domain and are therefore limited to this domain and are forever incapable of perceiving any higher domain that gave rise to our universe.

Like "The Matrix", only an external intervention from the higher domain would ever clue us in if the higher domain contained sentient intelligent life, but even then it would have to be in a form we could perceive and understand in our domain.

Ants don't understand anything about industrialization and synthetic textiles when they are being stepped on. But even then that's an over simplification that isn't even valid as ants and humans are of the same universe, so that example doesn't even begin to convey the inability to perceive something beyond our realm. Imagine trying to explain our universe to someone from a universe without gravity or electromagnetism. Its a paradox like trying to define a word by using the word itself. There would be no equivalence to explain one universe in terms of another.
Yeah I basically agree, though you've said it much better than I could've.

We recently discovered that particles slightly favor matter over antimatter. It has something to do with a property of certain quarks, but it's a bit over my head.

D-Branes. We are a holographic projection. Our universe is when two branes touch. It's fairly simple, really.

It was created from nothing.

You don't know that. You can't possibly know that.

All the energy that is in the known universe was created from the big bang.

You don't know that, either, and it's not something you can know.

Which was nothing before the big bang. Where did the energy come from. There was nothing.

Explain that scientists.

Stop being a dumbass.

The complete physical or mental information flowing from a single particle inside this universe is enough to overwhelm any physical device or mental realization by the cleverest beings inside our possible universe.

Somethings will forever remain unknown or unrealized.

There is no limit to calculating the number Pi or squareroot 2.

But such logical constructs despite logical existence shall always defy an completely accurate estimation. We can fill all of this universe with the most accurate measure of square root 2 with the ultimate logical machine and still not be ever complete sure about it.

Godel's theorem describes that all sets of logical will always be reduced to such statements that some rule derivations will be will always be unexplainable. This means no set of logic can ultimately escape the power of assumption. Somethings must always be assumed and logic reduce such basic set of assumptions.

In this sense, all we see are mere shadows of the so called reality.

The true physical information of this universes defy any levels of sensation of humans like us. It can be said that each of us live in our own universe of realized and unattainable possibilities.

Before the Big Bang there was the Big Boom. And before the Big Boom there was the Big Bam. And before the Big Bam there was the Big Blap. And before the Big Blap there were monkeys.

By the way, the answer is 42.

Hawking says that asking what was before the big bang could be a pointless
question, comparable to asking what lies south of the south pole.

But what irks me is the nonsense opinion that because we can't scientifically explain it right now it's unexplainable. They are working on it. Perhaps something came from nothing, perhaps our universe came from a white hole and there are multiple universes.... perhaps there was a creator. But if there was a creator, then it certainly isn't anything like the hundreds of fake gods that humans invented.

It's not so much that they can't explain it, it's that using the model they are using the question is meaningless. The what's south of the south pole is a good analogous question.

Now, yeah, their model might be completely wrong but that's a different issue.
