I don't understand any of this

[Fragony]

But it's apparently a great breakthrough. Bing Bang.

My greatest que?

'Theory holds that this would have taken the infant Universe from something unimaginably small to something about the size of a marble. Space has continued to expand for the nearly 14 billion years since.'

Where did that infant Universy exist in before? 4th dimension? Some time space anomaly? Behind me when I am not looking?

[Kagemusha]

Dont worry Frags. You are not alone in the crowd who have no idea about what this really means. Im sure our less intellectually challenged members will soon come to enlighten the rest of us, what is this fuss about.

[HoreTore]

If thee was no movement prior to the Big Bang, was there a "before"?

[Fragony]

Who cares, let's build warp-drives.

[Kadagar_AV]

Well, according to M-theory...

Imagine two sheets hanging out to dry. They will of course ripple in the wind. When the two fabrics meet, a "Big Bang" occurs.

Now, as to what the two sheets represent, and what would cause the wind... Oh well, let's just say it causes me an headache when I try to dwell into it.

It's either Chuck Norris sneezing or God. You can pick whichever you think is likelier.

I can agree on it maybe being a god. Question would be which one

[Myth]

Hawking states that the state of the universe prior to the big bang was a singularity, thus the laws of physics did not apply to it. it therefore, has no way of influencing the events after the big bang, and we have no way of explaining it as the rules do not apply to it. Thus, it can be ignored. Also, the light from the big bang was sort of discovered some decades ago, at least so he says in "A brief history of the universe". We also know that the universe is expanding rapidly and it is outspeeding its own gravitational pull, thus it will not collapse back into a singluarity.

How did that one proto-singularity, out of which all the universe appeared, come into being? I think we are a thousand years too early in asking this question. We are like dogs, trying to comprehend the moon.

My money is between Zeus, Ra, Odin and Tengri. I cannot see anyone less badass creating this universe.

The perfect scientific assessment of God. The believer would assert that far from being ignored, no other question is as significant.

I take your point, but I would replace 'dogs' with "children." We are not lacking in intelligence, we only suffer a surfeit of ignorance.

Uhm... Last I checked that was just a rival theory.

Leading theory is that dark matter will eventually start bringing things back to the centre, no?

[HoreTore]

We still have no clue what dark matter is(hence the term "dark"), so any theories on how it ties into the bigger picture is far from complete.

[Kadagar_AV]

Yeah... I didn't state it as fact, I just think it is currently the leading theory in the circles that have the brain capacity to actually understand this.

[HoreTore]

There is a belief that these theories will be the leading theories once we have figured out what dark matter is.

You're jumping the gun a bit, I'm afraid...

We could, after all, end up discovering that there's no such thing as dark matter at all, like how we discovered that light does not need to pass through an aether.

Honestly, I for one don't have the brain capacity to follow a percentile of what those minds are into.

I deeply respect them though.

[Sarmatian]

So, if universe was infinitely small, and it keeps expanding, does this mean there's an end to it? What's there? I'm imagining Douglas Adams as border guard...

[Papewaio]

If it keeps expanding it will smear the energy over an ever increasing volume.

Imagine you are in a old cold mansion huddled in a room around a star brand pot belly stove with a single log left to burn. Then one of your companions Lee Expansion starts to open the doors to all the rooms. The room you are in will start to share its heat with all the other rooms and yours will get colder. Also your fuel is running out, and in time the last log burns out leaving the room to cool down. Then Lee starts to open all the windows just to put the boot in and you all freeze to death.

If the universe expands the hydrogen that makes stars will be smeared out over further distances making nebula less and less frequent. Nebula are star nurseries so we will run out of stars and lose our heat sources as the universe gets bigger and bigger. So in the very very far future the universe will be very large but also very cold.

[HopAlongBunny]

Sounds like nonsense.
Everyone knows the universe was danced into existence and will be danced into annihilation.
Fortunately, everything in between is dancing.

[Husar]

So God already existed before the beginning of time?
For how long?

Yes, the cold death, but what is outside the universe? Beyond the border.

[Kadagar_AV]

There is no border, it's a loop.

Yes, the universe is expanding, but not out into anything.

Imagine that you blow a balloon up, that is basically what has happened since big bang. The whole "being" of the universe is on the surface/fabric of the balloon.

WE are on the surface / fabric of this balloon, thus our furthest point is the place of origin.

GAH!!

I neither have the English nor brain to explain or grasp all this. I do however do my best to try to explain it to people as stupid as I from the very limited knowledge that I have.

[rvg]

And just like a balloon one day the entire Universe goes "poof" in one Big Rip. Very sad, mostly because it makes human life and existence in general utterly absurd and pointless.

The big rip is one theory...

Another theory is a universal strive for complexion. The ultimate complexion would be "god".

Couple that with dark matter and a universe that moves out, to move back in, in a more complex state than it was before... And you get close to understanding my "religious" beliefs.

Here's a possible eye opener for the people of a false religion:

An atomic scientist is actually atoms trying to understand themselves.

How's that for a joke

Reminds me of St Lazarus.

Two points to consider

1) heat death for the natural universe may occur but it might not wipe out life. It may be possible to harvest energy in other ways

2) multiverse and traveling between them. Sure this overgrown marble is dying but we might be able to skip/create other 'verses.

[a completely inoffensive name]

The 2011 Nobel Prize for Physics was given "for the discovery of the accelerating expansion of the Universe through observations of distance supernovae." As it stands right now, whatever dark matter is, it is not sufficient to shrink the universe, as we are talking an acceleration in the growth, not just that it is growing.

So, if universe was infinitely small, and it keeps expanding, does this mean there's an end to it? What's there? I'm imagining Douglas Adams as border guard...

There is a distinction made between its size and whether or not it is bounded or unbounded. Basically Earth is finite but unbounded, there is no edge of earth, you just keep walking around. I believe the most popular view right now is that the universe is both infinite and unbounded.

Fun stuff we are discovering. People seem to not grasp what is amazing about this.

Before this the furthest back we could "look" is 380,000 years after the big bang, because our "oldest" observations was the Cosmic Microwave Background. Now, with these gravitational waves we have evidence as to what happened during the inflationary period, the inflationary period was anywhere from 10^-36 to 10^-32 seconds after the big bang.

So now we have a better picture of what happened about 0.000000000000000000000000000000000001 seconds after the big bang.

Terry Pratchett wrote about the long-stockings of time.

Basically, every decision ever taken is like dropping a marble down a pair of long-stockings. You don't know which leg the marble is going to come out off, but it doesn't matter as the universe simultaneously is split in two, hence the multiverse.

I don't mean to ridicule you, Pape, it's just the best description of a multiverse I have heard except for the descriptions I don't understand.

So, in one multiverse I am right now having a threesome with Jessica Alba and Alizée in their prime...

However, in this multiverse I am gonna take my White Wolf up to a night run up a mountain, to howl at the full moon - then off to bed... I am more than content :)

No.

You are right about the prize, but wrong about its implications to what I said.

Easily put: Expansion SHOULD be more rapid from a dark matter point of view.

Don't ask me to explain why, it blows my mind going anywhere near these questions.

I think the ratio of neutrons to protons gives a fairly good observation much earlier then 380k years after the Big Bang.
