( A HALF AN HOUR CONFUSING READ.)
Theoretical Science has endeavoured to explain what the universe is made up of with some success until it comes to the vast emptiness of spaces.
Perhaps some logical thinking is needed to enable us to understand how the universe began.
It requires developing a better theory of how space, time, and matter are related.
Every single second of every single day, you are being bombarded by trillions upon trillions of subatomic particles, showering down from the depths of space. They blow through you with the strength of a cosmic hurricane, blasting in at nearly the speed of light. They’re coming from all over the sky, at all times of the day and night. They penetrate the Earth’s magnetic field and our protective atmosphere like so much butter.
These tiny little bullets are called neutrinos. Neutrinos have this annoying habit of changing character as they travel. That’s right, as a neutrino travels in flight, it can switch masks among the three flavours.
Although many subatomic particles break down into other particles, so far no one has caught the decay of protons or neutrons, which make up the nuclei of atoms.
Neutrinos continually challenge everything we know about physics.
Neutrinos are the ghosts of the subatomic world. Interacting via only the weak nuclear force, they can pass through matter without interacting nearly at all.
The visible universe—including Earth, the sun, other stars, and galaxies—is made of protons, neutrons, and electrons bundled together into atoms.
(Protons and neutrons are particles called baryons, and baryogenesis means the creation of baryons. (Understanding this requires more brain power than I have.)
The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 per cent) and a force that repels gravity known as dark energy (70 per cent).
Perhaps one of the most surprising discoveries of the 20th century was that ordinary, or baryonic, matter makes up less than 5 per cent of the mass of the universe.
Although astronomers understand what the universe was like just a few seconds after the Big Bang, no one yet knows what happened at the instant of the Big Bang – or what came before.
The key assumption of this model is that just before the Big Bang, space was filled with an unstable form of energy, whose nature is not yet known.
Energy comes in different forms:
- Heat (thermal)
- Light (radiant)
- Motion (kinetic)
- Nuclear energy
- Energy sources are divided into two groups: Renewable / Nonrenewable.
In fact, all the matter in the universe could have arisen from a bit of primordial energy weighing no more than a pea. At some instant, this energy was transformed into the fundamental particles from which arose all the matter we observe today.
This energy in the form of light comes in discrete packets called photons.
All the results, the origin of space and time rest with the Big Bang.
This leaves us with the question what caused the big bang, what was there before.
According to the Big Bang model, the Big Bang took place everywhere in space (not just at a point).
The Big Bang could have been triggered when our own universe collided with a “parallel universe” which set off tiny gravity waves in motion.
After the Big Bang, all of space was filled with matter so hot that it glowed -In fact, a steady stream of this light is continuously arriving at Earth, from distant regions of space, having travelled for billions of years to get here.
So the afterglow of the Big Bang IS still filling the universe today- with cosmic microwaves.
This is where it starts to get complicated.
Light is being distorted and magnified by massive, invisible clouds of dark matter in the foreground-a phenomenon known as gravitational lensing.
The inflationary model predicts that Big Bangs are continually taking place in other regions of space – and string theory suggests that these other mini-verses may be so different from our own that even the laws of nature and the number of dimensions of space may be different.
The inflation model makes several testable predictions. One of the most important is that the primordial energy would have been “lumpy” – i.e., unevenly spread out in space – due to a kind of quantum noise that arose when the universe was extremely small.
However, there is not enough mass to support a universe that is closed so it expands forever. New space is continuously coming into existence between galaxies. Thus, the creation of the universe – or at least of the space in the universe – is a continuous process that is still taking place.
If there is enough mass, the gravity attracting all the pieces to each other will eventually stop the expansion and pull all the pieces of the universe back together in a big crunch. The universe would then be closed universe made up of dark matter, dark energy, and antimatter.
For something that supposedly takes up 80 per cent of the total mass of the universe, we don’t know a whole lot about dark matter, antimatter, or dark energy.
There is little or no evidence supporting their existence.
We are yet observed dark matter directly, however, scientists are confident it exists because of the gravitational effects it appears to have on galaxies and galaxy clusters.
If this is so dark matter came into existence before gravity.
However, if dark matter and dark energy are interchangeable, the same thing and do not absorb or emit light and interacts with visible matter through gravity, Gravity came first for it to be able to interact in the first place.
Is dark matter even real? And if it’s not, then is everything we know about gravity wrong?
One leading hypothesis is that dark matter consists of exotic particles that don’t interact with normal matter or light but that still exert a gravitational pull but there are multiple forms of gravity and all are attractive forces irreverent of their strength.
According to another idea, dark energy is a fifth and previously unknown type of fundamental force called quintessence, which fills the universe like a fluid. A repulsive force that counteracts gravity, keeping the universe from collapsing in on itself.
I ask why the strange force exists in the first place.
For example, why is the speed of light not faster than it is?
Why are electrons so much lighter than the protons they orbit in atoms?
Why are the constants and laws of nature just so, and not different?
If there was nothing, to begin with, then where did the laws of nature come from?
How did the universe “know” how to proceed?
And why do the laws of nature produce a universe that is so hospitable to life?
What we do know is that if these fundamental laws and constants were even slightly different from what is observed, then life as we know it would not exist.
If the universe is expanding what is it expanding into?
If the universe is infinitely big, then the answer is simply that it isn’t expanding into anything; instead, what is happening is that every region of the universe, every distance between every pair of galaxies, is being “stretched”, but the overall size of the universe was infinitely big, to begin with, and continues to remain infinitely big as time goes on, so the universe’s size doesn’t change, and therefore it doesn’t expand into anything.
The answer is that we really don’t know what, if anything, the universe is expanding into. The space between the galaxies “stretches”, so we have no way to see “outside” to get a sense of the entire shape and figure out where the centre is.
So we don’t think there is any way to observe or measure what is beyond unless it had some effect on us that we currently don’t know about. It would be really weird to imagine reaching the “end” of space.
What would it look like, for example?
If the universe is indeed infinite, it doesn’t have anything to expand into.
So the total size of the universe is the same!
You and I aren’t expanding, the Earth isn’t expanding, the sun isn’t expanding, even the entire Milky Way galaxy isn’t expanding.
That’s because, on these relatively small scales, the effect of the universe’s stretching is completely overwhelmed by other forces (i.e. the galaxy’s gravity, the sun’s gravity, the Earth’s gravity, and the atomic forces which hold people’s bodies together).
It is only when we look across far enough distances in the universe that the effect of the universe’s stretching becomes noticeable above the effects of local gravity and other forces which tend to hold things together.
Massive collisions are produced as pairs of black holes or neutron stars — both incredibly dense objects left behind after a star explodes — draw close to one another.
As they dance, they cause gravitational waves to ripple outward until the objects eventually collide. This explosion is more than just a pretty sight; it is the main source of the elements that make up our planets and all the other objects in the night sky.
So how are the elements that make up matter created in the first place?
From what element are all other elements made?
Elements are subdivided into several categories based on where they originated from: The Big Bang, Cosmic Rays, Large Stars, Small Stars, Supernovae, and Man-Made labs.
Everything is made starting with hydrogen. But where did the hydrogen in the universe come from? From a proton and an electron.
So maybe it is particles that came first.
Where do those fundamental particles, and their even more fundamental particles come from? No one knows because it would require knowing exactly how the universe began, and where all matter in it originated from.
Humans will never know that.
When particles of both collide, heat would naturally move from the warmer body to the colder one, causing the warmer body to cool ever so slightly.
Humans and their galaxy have about 97 per cent of the same kind of atoms.
A new element is discovered, by smashing atoms together to see what happens.
Each element emits distinct wavelengths of light from within a star they are substances that cannot be broken down further.
There are several ways to consider the composition of the human body, including the elements, the type of molecule, or type of cells.
Some 60 chemical elements are found in the body, but what all of them are doing there is still unknown. Roughly 96 per cent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. For now, we can only say for certain what 20 or so elements are doing.
Although humans share most elements with the stars, the proportions of those elements differ between humans and stars. For example, humans are about 65 per cent oxygen by mass, whereas oxygen makes up less than 1 per cent of all elements measured in space.
So here are my logical conclusions:
The assumption here is that “before the big bang” actually means something.
The standard cosmological model is based on time and space both being countable numbers in natural units. This assumes we have a meaningful definition of void and exist without our universe being around.
Our model does not provide these definitions, so our assumptions rely on some false hypothesis premises.
I’m not going to say there was emptiness or nothingness before, at least not in the sense you mean them.
Nothing does not indicate emptiness (where there is no matter) but indicates the NOT existence.
Only with Quantum Mechanics is it hypothesized that even in nothing can be created with quantum fluctuations the Universe. I have not understood how it is possible but it seems that there are Physicists who imagine this possible.
Why is there something, instead of nothing?
Go one step back and remember that before vacuum, you have to have space and before space, you have to have a dimensionality.
Nothing was Fluctuating.
The WHOLE UNIVERSE (and then some) is a Cold Black Hole.
Currently, we consider Black Holes to be gravitationally induced space deformations where not even light can escape.
THIS IS A FALSE LOGICAL FLAW SINCE BLACK HOLES ARE MADE UP BY MATTER AGGREGATES.
THEY PRODUCE TIME SPACE DARK ENERGY DARK MATTER ECT AND THE BIG BANG.
SO BLACK HOLES CAME FIRST.
HOWEVER, Without time, we and THE UNIVERSE wouldn’t be here.
SO TIME CAME FIRST AND WILL EXIST EVEN IF THERE IS NOTHING.
Even physicists agree that time is one of the most difficult properties of our universe to understand. … In the sciences generally, time is usually defined by its measurement:
The indefinite continued progress of existence and events in the past, present and future regarded as a whole.
Clearly, time is not an object or substance we can touch or see.
It may be considered as potentially infinite. We remember the past but we don’t remember the future. There are irreversible processes.
Even in empty space, time and space still exist.
So there’s an infinite number of universes behind us and an infinite number of universes coming ahead of us.
All human comments appreciated. All like clicks and abuse chucked into the black hole.
