These theories are meant to be verified


 1  The theory — is it possible for the Milky Way Galaxy to be formed like this:

NASA JPL | VIDEO
 1  The Death Of A Star

When a giant star dies, it explodes as a supernova - spewing dusts & gas all around, and leaving behind a black hole at its center. As this giant star was spinning, imagine it like a spinning giant ball exploding inside a pool.
 2  A New Born Galaxy

So the resulting spinning current made the dusts & gas swirl around the black hole. Through time, these dusts & gas collided, clumping and growing bigger. & when they are big enough, they burn, birthing stars around the black hole. This became the Milky Way - the galaxy we live in.
 3  The Solar System

Then a star was born inside the Milky Way, it is the Sun. And the Sun spins. The current of this spin made the surrounding dusts & gas swirl around the sun - like a big ball spinning inside a pool in which smaller balls follow its current. These dusts & gas collided as well, clumping and growing bigger. Finally, they became planets orbiting the Sun. This is the Solar System. [video]
 4  Planet Earth

Inside the Solar System, the Earth was born. As time passes, debris continuously impact Earth, in lesser extent. (phew!) Every year, the Earth have meteor showers. & at times, asteroids which caused extinctions.


 2  The theory — is it possible for the Universe to end and start anew like this:

SUPERNOVA

and blown into the sur (صور) [Q39:68]

... ما هو الصور

יום תרועה   THE DAY
When the universe reaches old age, all the stars will exhaust their fuel and die as stellar explosions. وإذا النجوم انكدرت [Q81:2] Then, when all the stars are extinguished, what's left behind are toasted rocks. So the universe will be full of toasted rocks, cold and dark with diminishing energy. واهية [Q69:16]

Without energy, the expansion of the universe will end. So will the universe becomes so cold, it contracts (rolls back) to its point of origin. السماوات مطويات [Q39:67], السماء مورا [Q52:9]

So along the way, the size of the universe becomes smaller and smaller, which spins it faster. This faster spin pulverizes the rocks into particles, as if in a blender, and it gets so small as if wind. * Every thing will be pulverized. كل شيء هالك [Q28:88] منفطر [Q73:18]

The universe becomes smaller and spins faster, accelerating particles to light speed


When this compression reaches its point of origin, it is very dense and highly pressurized.
Eventually, the energized particles flew apart. And a new universe starts again.

بسم الله الرحمن الرحيم

... يوم نطوي السماء كطي السجل للكتب كما بدأنا أول خلق نعيده ...

... the Day when We shall roll up the heavens like a scroll rolled up for books
as We began the first creation, We shall repeat it ...
[Partial Holy Quran 21:104]

I seek refuge in Allah SWT from errors
Only Allah SWT Knows Best والله أعلم

On a note, yay the ancient malays was right in calling this "cakerawala" (disc) الحمد لله

[1] Largest Ever 'Age Map' Traces Galactic History
BBC
Astronomers have measured the age of 70,000 stars across the Milky Way and put the results into a galactic map. It confirms what was already suspected about our galaxy's growth: it started in the middle and grew outward. This can be seen in the abundance of old stars near the centre of the disc.

[2] Astronomers Witness Supermassive Black Hole Swallowing A Star
TechTimes | Science
For the first time ever, astronomers were able to witness a supermassive black hole swallowing a star that is as huge as the Sun... The star was disintegrated and created a disk of debris around the black hole prior to its total disappearance into the horizon. The resulting pieces were sent across space at a rate near the speed of light by strong magnetic fields, creating plasma jets.

[3] Missing Link Between Turbulence In Collapsing Star
UC Berkeley | Nature
... as a rotating star collapses, the star and its attached magnetic field spin faster and faster, forming a dynamo that revs the magnetic field to a million billion times the magnetic field of Earth. A field this strong is sufficient to focus and accelerate gas along the rotation axis of the star, creating two jets that ultimately can produce oppositely directed blasts of highly energetic gamma rays.

[4] An Orphaned Planet
National Geographic | UC Berkeley
About 300 light-years away, a giant planet has been evicted from its starry neighborhood... Scientists suspect giant gravitational nudges from another planet — or perhaps from a passing star — sent it zooming outward. It’s the same kind of process that scientists blame for the billions of rogue, starless worlds that wander our galaxy.

Electron Degeneracy
Wikipedia

... all electrons are stripped from their parent atoms. The core of a star, once hydrogen burning in nuclear fusion reactions stops, becomes a collection of positively charged ions, largely helium and carbon nuclei, floating in a sea of electrons, which have been stripped from the nuclei.

Degenerate gas is an almost perfect conductor of heat and does not obey ordinary gas laws. White dwarfs are luminous not because they are generating energy but rather because they have trapped a large amount of heat which is gradually radiated away ...

In degenerate gases the kinetic energies of electrons are quite high and the rate of collision between electrons and other particles is quite low, therefore degenerate electrons can travel great distances at velocities that approach the speed of light.

Instead of temperature, the pressure in a degenerate gas depends only on the speed of the degenerate particles; however, adding heat does not increase the speed of most of the electrons, because they are stuck in fully occupied quantum states. Pressure is increased only by the mass of the particles, which increases the gravitational force pulling the particles closer together ... when the mass is increased, the particles become spaced closer together due to gravity (and the pressure is increased), so the object becomes smaller. Degenerate gas can be compressed to very high densities, typical values being in the range of 10,000 kilograms per cubic centimeter.
