So this stuff occupied a space of a proton according to Friedmann's solutions to Einstein's field equations, right?Actually yes, that is precisely what big bang theory is. There existed stuff, that we cannot ever observe more than 10E-33 s before the big bang and the big bang happened to it. The stuff expanded rapidly.
I know you can't answer the question I asked you about the cosmic background radiation. Any explanation for the origin of the universe must begin there. Can you tell me anything at all about the cosmic background radiation other than you just don't know?We've had this discussion before. You don't know what you don't know.
it's not a myth. No one has proven that hypothesis wrong.
Not clear to me what utility the ratio has.
Dr. Carl Sagan said: "We are a way for the cosmos to know itself."
Thank you for not being an ingrate. I amn't too.
We know.
Einstein explained that while in our terrestrial (Newtonian) experience matter & energy are two separate things, that they can be converted, one to the other. That's what: E=M*C e 2 is all about.
When we detonate an atom bomb, or an H-bomb, we convert matter into energy.
Yet at particle accelerators like CERN, we've converted energy into matter. So Einstein's equation works both ways.
zw used the term "created". The process Einstein & I described is rather more a conversion than a creation.
It is possible for matter to have a beginning. In a closed universe the gravitational energy which is always negative exactly compensates the positive energy of matter. So the energy of a closed universe is always zero.
So nothing prevents this universe from being spontaneously created.
Because the net energy is always zero.
The positive energy of matter is balanced by the negative energy of the gravity of that matter which is the space time curvature of that matter.
There is no conservation law that prevents the formation of such a universe.
In quantum mechanics if something is not forbidden by conservation laws, then it necessarily happens with some non-zero probability.
So a closed universe can spontaneously appear
- through the laws of quantum mechanics - out of nothing.
And in fact there is an elegant mathematical description
which describes this process and shows that a tiny closed universe having very high energy can spontaneously pop into existence and immediately start to expand and cool. In this description, the same laws that describe the evolution of the universe also describe the appearance of the universe which means that the laws were in place before the universe itself.
Why isn't it possible? With God all things are +possible.
from sear's notes, according to author Simon Winchester:Can you provide a theory on how it got there other than the leading theory which says it was created from nothing and explain how all of that cosmic background radiation got there?
BUT !!We don't know "where from" the energy of our universe comes (wherein some energy froze out to matter) because as far as we are able to know it existed no "where from" (=space) and "come"(=time) in the beginning.
BUT !!
To consider it a valid question we must interpret this question as an issue of chronology, of time, of sequence of events. Right?
If we consider time as something other than a continuum, then the concept of where did the material from the big bang come from is undefined, to the layman, meaningless.
Considered another way, the notion of the big bang is sudden change.
If the big bang was a change in space,
nothing was there, not even nothing was there,
and suddenly there was something where there hadn't been anything.
If a change in time?
That doesn't address the formation of the cosmic background radiation but thanks for trying. I'm sure you gave it your best.from sear's notes, according to author Simon Winchester:
Irish Bishop James Ussher claimed that the 6 Biblical days of creation began 9:AM Monday the 23rd of October 4004 BC.
And while this may be regarded by some as religious (Christian) doctrine, there is some contradictory evidence, including the fossil record. And because the fossil evidence refutes the 6 day creation idea, the doctrinal solution of "vis plastica" (plastic force) was created. This divine plastic force supposedly inserted fossils into rock to remind us of the omniscience and omnipotence of god. The fossils therefore were not, according to vies plastica (sp?), evidence of life in general or evolution [more gradual than 6 days] in particular. Instead they were claimed to simply be evidence of god’s presence in the universe.

So it not exists. <=> ¿division by zero in our thoughts? Afterwards is everything plaiusible. The question in this case is: "What ripped the nothing into a uninverse?"
Spontanous? How - if it has no energy?
Aha. What do you do "spontanous" if you have nearly no energy?
Mass curves the space - it is not the curvature of the space - it causes the curvature. The space is flat (what's proven).
¿Which formation?
Erhaltungssätze? Quantenamechanik? ... Wha do you say here? What is not "forbidden" (and what means "forbidden" in this context at all?) What do you say here?
Space is flat, so the universe is not closed.
If space exists then it is mathematically possible that a universe is able to create a whole universe. But when we say the universe expands then we think that the space itselve expands. So if we go back in time then the space becomes more little and little and little and approximates to zero size. And if in this little space exist as many quantum fluctuations as it are existing in the same amount of space all around - did we anywhere in the titanic universe see a quantum fluctuation which creates the positive and negative energies of a new universe?
Is it? Did you read it? Did you understand it?
Exaclty. A circle was always a circle and never evolved. Since the universe is. But "before", where no before was - and no "where"? What to say about???
Spontaneous creation of the universe from nothing
An interesting idea is that the universe could be spontaneously created from nothing, but no rigorous proof has been given. In this paper, we present such a proof based on the analytic solutions of the Wheeler-DeWitt equation (WDWE). Explicit solutions of the WDWE for the special operator...arxiv.org
As near as I can tell the distinction is that in a false vacuum paired particles pop into existence, annihilate each other and leave behind radiation as per E=mc^2.The title is wrong. It should be "Spontanous creation of the universe from vacuum." A vacuum is not nothing, that's why they are able to calculate this. What I don't understand is what they understand under a "false vacuum" in which a bubble of "true vacuum" appears thanks of Heisenberg.
Physicists use often an since ever existing and never ending space in their calculations. But this is not what the theory of relativity tells us. It tells us the space expands on its own. Everything started about 13.8 billion years ago ... from nothing = not from anything what we are able to say (or calculate) anything about.

Relativity can only describe what happens to the universe after it appears.
Are you sure relativity tells us that space expands on it's own?
I don't know why the space expands - but if I think about then it means we live in an universe where we always will see an expanding universe - independent where we are. So if we will travel through the universe we are always in the middle and the universe will still expand from all points into all directions. This means the universe is without edge or border and all points are always in the middle - totally independent where we are. When I understood this the first time my spontanous reaction had been to say: "Typically god".
