I am sure like me you have at some time looked up an wondered where does space stop.
My unscientific language does not seem to lend itself well to this topic nor my understanding of the Universe or God.
The absolute origin of the universe, of all matter and energy, even of physical space and time themselves is and will be a mystery long after I have departed this world.
Some how for me the Big Bang singularity contradicts the perennial naturalistic assumption that the universe has always existed.
It seems impossible even if proven chromatically that all the matter that exists today was once squished into an infinitely dense, infinitely tiny, ultra-hot point called a singularity. Into to a tiny fireball that then exploded and gave rise to our early universe.
Lets say that again.
“All matter in the universe was once in a single point — the Big Bang singularity.”
But that’s not quite true because in Einstein’s formulation, the laws of physics actually break before the singularity is reached.
So what was there before the bang?
This is cosmology’s most fundamental question:
How did the universe begin?
The universe as we know it almost certainly started some 14 billion years ago. But was that the absolute beginning, or was there something before it? This question seems like the kind of question that can never be truly answered because every time someone proposes a solution, someone else can keep asking the annoying question: What happened before that- God?
“If God existed in time, once time existed and time had a first moment, then God would have a first moment of existence.”
There would be a moment before which He did not exist, because there was no ‘before’ that moment . . . . Yet even if He . . . had a first moment of existence, one could still call God’s existence unlimited were it understood that He would have existed even if time did not.
I suppose it might be easier to get you head around the Psalmist’s description of God: ” From everlasting to everlasting”
I must admit it difficult to see how can anything, that exists from eternity, have a cause, since that relation implies a priority in time and a beginning of existence but Religion’s central beliefs is that mankind needs a savior.
However, that belief becomes hard to sustain convincingly if we posit that a god created the universe and then let things make themselves via purely physical processes, because then sin and death aren’t the fault of man, but merely natural byproducts of the god-makes-things-make-themselves process. Sin and death, on that scheme, are no longer man’s fault, but God’s choice, for he must have known that these things would emerge via the stated process.
Still confused. Don’t worry so am I.
When we look up we see a universe filled with grand cosmic structures — galaxies, clusters of galaxies, clusters of clusters called superclusters, and clusters of superclusters called galaxy filaments — some of the latter stretching a billion or more light-years across.
It therefore does not make sense to me that the universe has a non-existent state (or nothing) and so must be eternal in the sense of being persistent rather than necessarily temporally eternal (presumably the universe does not require the quality of time to exist).
So, strict nothing cannot logically or physically exist.
It’s simply hilarious that the Big Bang is asserted as having started with a form of physics that is completely unknown, and to validate it we have to use “dark energy” that is equally unobservable and unmeasurable.
These days we see big ideas like this do change, and it’ll be fun to see if this one does!
Most of us understand the Big Bang as the idea that our entire universe came from a single point, what astrophysicists call a “singularity.”
But what if we did not need a singularity to have a Big Bang? Or could our universe’s Big Bang be an implosion of a previous universe?
What if our universe has no beginning or end? It existed forever as a kind of quantum potential before collapsing into the hot dense state we call the Big Bang.
What if the Big Bang did not start with a singularity – a point in space-time when matter is infinitely dense, as at the center of a black hole. This would eliminate the need for a single infinitely dense point from which our universe sprang some 13.8 billion years ago. ( to be more precise)
However the big bang has been a fact of most of our lives since we were born. Presented as some sort of explosion that caused expansion that is to this day still expanding and will continue to do so for entirety.
Where does that leave us.
According to present day scientists when we look up we are looking into the past not the future.
However consider the following.
- Whatever exists has a reason for its existence, either in the necessity of its own nature or in an external ground.
2. Whatever begins to exist is not necessary in its existence.
3. If the universe has an external ground of its existence, then there exists a Personal Creator of the universe, who, since the universe, is timeless, spaceless, beginningless, changeless, necessary, uncaused, and enormously powerful.
4. The universe began to exist.
From (2) and (4) it follows that
5. Therefore, the universe is not necessary in its existence.
From (1) and (5) it follows further that
6. Therefore, the universe has an external ground of its existence.
From (3) and (6) it we can conclude that
7. Therefore, there exists a Personal Creator of the universe, who, since the universe, is timeless, spaceless, beginningless, changeless, necessary, uncaused, and enormously powerful.
And this, as Thomas Aquinas laconically remarked is what everybody means by God.
Now, in atomic processes, the notions of space and time are no more than statistical notions ; they fade out when applied to individual phenomena involving but a small number of quanta.
If the world has begun with a single quantum, the notions of space and time would altogether fail to have any meaning at the beginning; they would only begin to have a sensible meaning when the original quantum had been divided into a sufficient number of quanta.
If the future development of quantum theory happens to turn in that direction, we could conceive the beginning of the universe in the form of a unique atom, the atomic weight of which is the total mass of the universe. The whole story of the world need not have been written down in the first quantum like a song on the disc of a phonograph. The whole matter of the world must have been present at the beginning.
So did the big bang happened everywhere.
Some are claiming that the cosmos as a whole—the so-called “multiverse”—is eternal, but that it contains infinitely many individual universes (a consequence of modern inflation theory). This eliminates the need for an initial singularity of the Big Bang.
The Big Bang itself, however, can still have happened.
Einstein described the universe as static, rather than expanding, but he later abandoned the concept as his “greatest blunder” after Edwin Hubble’s 1929 discovery that all galaxies outside our Local Group are moving away from each other.
Rapid inflation in every direction also explained why the universe we now observe is so homogeneous, and why the temperature of the background radiation left over from that primordial blast is uniform, in every patch of the sky, to one part in 100,000. The process of inflation had to be eternal, meaning that once it started, it never fully stopped.
If the universe were always inflating, and always expanding, would that imply that the universe itself was eternal and had no beginning?
Nothing can be created from nothing.” energy can neither be created nor destroyed, we owe our existence to the humblest of origins: nothing itself.
A universe created from nothing is likely to be tiny, indeed — far, far smaller than, say, a proton.
Come from nothing in the sense of their being no space, time or matter, something is in place beforehand — namely the laws of physics.
But where did the laws of physics reside before there was a universe to which they could be applied? Do they exist independently of space or time?
Quantum mechanics says that the behavior of tiny subatomic particles is fundamentally uncertain. This is at odds with Einstein’s general relativity, which is deterministic, meaning that once all the natural laws are known, the future is completely predetermined by the past.
Quantum Mechanics also says that what ever can happen, does happen. That means that we should be seeing Universes popping put of nowhere spontaneously all the time.
Neither QM theories explains what is dark matter. An invisible form of matter that exerts a gravitational pull on ordinary matter but cannot be detected by most telescopes. It is made of what?
A part of string theory known as string gas cosmology predicts that the universe once had a long-lasting static phase, while other theories predict there was once a cosmic “bounce,” where the universe first contracted until it reached a very small size, then began expanding.
In the end none of us a supply a creditable explanation.
When we get more powerful telescopes that can see “further back in time” (or farther away in physical space), we’ll start to see a wide array of galaxies, both old and young that would be common in any direction we would choose to look . . . because it’s the same universe everywhere.
Sorry that’s the best I can come up with. There are a few links below to help you make your mind up.
There is no Universe of existence other than now and now never comes into being.
