a singularity is not nothing, what happend before it we have no idea

Time is cyclical.

The big bang that begins the universe is also the big crunch that ends the universe.

>>8568782
>there was nothing
That makes no sense.

>>8568782
What is the latest? Is the net energy in the universe zero or not?

>>8568801
Lol nice conjecture

Yes, for the universe came from an exploding object called "nothing".

>>8568801
There is no data that supports the big crunch theory (even if i find it appealing)

>>8568787
>singularity
meme word

There is no such thing as a 'beginning', there are just a bunch of 'presents'.

No it isn't

For the last time : the name Big Bang is an ironic named given by Fred "proto-butthurt/sci/entist" Hoyle.

People who came with this theory (Lemaître & cie) never said it was an explosion, but just a rapid expansion of the original singularity to a new frame that we call the space-time nowadays.

>>8569089
I've been on Sci for some time now and I'm kinda starting to doubt that

>>8568782

If you take into consideration string theory and evaluate it with the axiom of choice, the big bang theory is undeniable.

>>8568886
I personally subscribe to the solid state theory, but there's no evidence for any of the theories, anyways.

what if space and time already existed and the big bang was just all the matter in the universe converged in one fucking huge black hole?

There is no solid state theory, you mean steady state you have no idea what you're talking about but you feel qualified to weigh the evidence. A steady state universe still cannot explain the isotropy and spectrum of the cosmic microwave background. Not to mention the fact it requires the ongoing creation of matter by completely undescribed means.

Studies in thermodynamics indicate that the total universal energy is preserved in all transactions; so your assertion that nothing existed prior to big bang is a false one, op. The properties and nature of that energy prior to big bang, however are still yet to be know. Big crunch is not going to occur. Presence of Galactic bodies moving in varying directions lead us to believe we are in an expanding universe; and again thermodynamic law determines that preserved energy will one transact into the surrounding environment as unusable potential energy and we will all die and shit.

>>8568782
It turns out that there is literally no such thing as nothing.

Einstein's equations predict a singularity in a black hole. The reason for this is that General Relativity isn't a complete mathematical model of the physical world and fails to correctly describe the physical phenomenon we know as a black hole.
Dumbass undergrad.

>>8568980
Not a thing that actually exists

>>8568782
So, before the beginning
there was nothing.

Then it expanded.

FTFY

>>8569199
How can gravity be anything but closed if it is always attractive? Haven't studied GR, but I don't understand the shape of the universe part.

>>8569678
>Studies in thermodynamics indicate that the total universal energy is preserved in all transactions; so your assertion that nothing existed prior to big bang is a false one, op.

Thermodynamics is built on inferences based on empirical observations. Whilst it holds for the processes we can observe and replicate, there is nothing to suggest that there are no circumstances where the laws of thermodynamics can be broken.

We aren't able to replicate the beginning of the universe, so we can't comment on whether thermodynamics laws hold in that process.

>>8570070
Gravity is always attractive and yet a spacecraft can escape if it can reach escape velocity. In the same way the universe can be expanding so quickly that gravity will never stop it from expanding.

I like this theory. It makes me feel all warm and fuzzy :)

>>8568967
Did you just assume his religion?

>>8569678
"Thermodynamics" would only be a binding law once the universe came into existence. Before that there couldn't have been any physical laws because "physical" as we know it was not a thing. Existence as we know it was not a thing.

Beyond that, you're also assuming there are NO conditions in which thermodynamics may break down, which could be true but it may not be true. We thought for a long time that Newtonian mechanics were solid, but later we learned that high velocities and large masses fuck up our calculations.

General relativity is not a quantum theory, therefore anything it predicts at quantum scales is irrelevant. i.e. the singularity at the center of a black hole

>>8568782
In the beginning there was space which contained everything and it expanded

>>8573465
The idea is that when you solve the EFE and get a black hole solution, their is a radial dependence so as r-->0 the curvature diverges. But studying the behavior as r-->0, is ignoring the QM behavior that needs to be accounted for once you reach a small enough scale.

how did space and time come to be?

big bang is a lie.

the earth is a huge terrainum. NASA is in place to push a cosmology lie.

evolution is a lie. blacks have more genetic diversity therefore they are the first people while whites have significantly less genetic diversity, which is the reason why whites have significantly more chances of having weak offspring with disorders.
you cannot make a human out of a whale. there was always whales and then there was always humans. genetic offspring upon frequent isolation and interbreeding causes failure.

I always giggle when I see people who believe that there was time or a 'before' the big bang.

So limited in intellect.

What if "universes" break off into "child universes" via black holes exploding which coincidentally contain less matter and energy than their parent universe?

Aka it's all just stuff exploding, spreading out and converging in clusters, and exploding again and our "observable universe" is just us being limited to what we can see from the gravitational shockwave combined with the fact that the other "universes" are spaced out far away from one another.

Our universe is a simulation run on a computer. Big bang was just someone starting the program run. Good luck finding out how things started wherever the simulation computer is located.

How easy was that? Next question.

>>8568782
You're mixing up science and religion you fool. As best as science can explain in the beginning there was everything. In one point, a point of infinite density.

It'll be literally impossible to know if its more likely to be big crunch or heat death

Either way the universe will rebirth, it just takes a fuckton longer in heat death

>>8579843
We can, and have, measured the rate at which galaxies are moving away from each other.
The universe is expanding at an ever increasing rate.
We are headed for heat death.

Is anyone else pissed off that we'll never know for certain where all this universe shit came from and how it all started

It's like knowing you're going to die before the greatest movie of all time is going to be released. Imagine dying a week before The Empire Strikes Back or some shit

Even if the human race eventually figures it out, I'll have been dead for like a billion years. Fuck that. I'm mad as hell

>>8568787
>what happened before
Someone in a higher dimension or relative macroverse or distant future simulated or initiated the big bang.

We are most likely an ancestor-simulation to see how exactly the world evolved.

No to both questions/statements.

Hubble and its thousand confirmations showed that universal acceleration is happening far faster than gravity can ever compensate for. No crunchies happening here, barring weird unforeseen shit or magi-tech level interference.

>>8580143
>Hubble and its thousand confirmations
Hubble was only tangentially involved in the supernova cosmology projects, most of the work was done at the ground based CTIO and various large telescopes like Keck for spectroscopic followup. There was only HST data for a couple supernovae in one of the projects.
