Extent of the Universe

Extent of the Universe 

 

There is no universal theory to explain the Universe and its extent.

The visible horizon limits the extent of the possible penetration of light.

Add to that our universe is expanding and bit by bit its outer limit is disappearing beyond our visibility.

Does that means that there is no matter beyond the limit of speed of light (the distance it has traveled so far)?

 

So our understanding is limited by visibility of events.

Anything beyond the visibility zone is unknown and a mystery.

How to solve this problem at least theoretically?

Our universe gives us the expression of Expansion.

What is driving this expansion?

In theoretical sense it is the dark energy.

Then there is the possibility of existence of dark matter.

Our inability to see dark matter within the visible range does not exclude its existence.

The void or space theory has its own limitations, the dark matter and dark energy gives us some scope of expanding our understanding of the totality of the universe.

At least some hope.

If there is (system of) expansion of the universe there ought to be a system of contracting universe, too.

The system of contracting universe should be the result of the absence of dark energy (theoretically that explains the expansion).

The contracting universe should lead to the formation of more and more dark matter as an end result.

The third possibility is that there is a system with neither expansion nor contraction (with or without matter within this system).

Where does this system fit in?

How does it behave?

This system cannot stay pretty stable anyway with two opposing systems of expansion and contraction.

One side the system might get drawn into the expanding universe and on the other side it gets sucked into the contracting universe.

The outcome is, its contraction and bringing the two opposing systems (expanding and contracting universes) closer.

In other words a collision course.

This collision course should bring about formation of more dark matter at the point of collision, in small bursts not catastrophically.

(This is why I do not expect (Big Bang theory) a sudden explosion of our universe which is based on the intelligent design, to fit in with the god theory and its creation).

This might explain the presence of dark matter within some spiral galaxies.

What happens when dark matter meets with the visible matter?

That is the bone of contention.

One possibility is that the Matter gets sucked in due to the enormous gravity within the dark matter with creation of black holes and wormholes.

The matter consists of only 5% and the dark matter and dark energy is 95% of the total.

If the above scenario is correct ultimately there is only dark matter and very little matter at all, left in the universe.

I think it is the other way around.

Dark matter turns into matter is small bursts.

This probably happens in the opposite end of the dark matter not visible to our eyes.

In other words, if matter collides with dark matter in dark holes an almost equal amount of matter or even more matter should be created to set in motion the formation of new galaxies.

If this scenario is possible presence of dark matter in the newly emerging galaxies is not something unexplainable.

Similarly little by little matter is exhausted and disappear (if we apply the principle of “state of flux” as a scientific principle) forming dark matter or a void explained above by neither expanding nor contracting system that may exist within the extreme poles of expanding and contracting universes, thereby limiting the likelihood of catastrophic events of collision.

We are yet to understand the 95% of the Universe.

The above is a theoretical discussion for young ones to explore and expand.

Mind you we are losing bit by bit of our universe to event beyond event horizon.

That is my explanation for existence of multiple universes.

Fact that we cannot see does not exclude their existence.

Stellar black holes — small but deadly

When a star burns through the last of its fuel, it may collapse, or fall into itself.
For smaller stars, up to about three times the sun's mass, the new core will be a neutron star or a white dwarf.
But when a larger star collapses, it continues to compress and creates a stellar black hole.
Black holes formed by the collapse of individual stars are (relatively) small, but incredibly dense. Such an object packs three times or more the mass of the sun into a city-size range. This leads to a crazy amount of gravitational force pulling on objects around it. Black holes consume the dust and gas from the galaxy around them, growing in size.
What is dark matter made of?
Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), have ten to a hundred times the mass of a proton, but their weak interactions with "normal" matter make them difficult to detect.

noun: dark energy; plural noun: dark energies

a theoretical form of energy postulated to act in opposition to gravity and to occupy the entire universe, accounting for most of the energy in it and causing its expansion to accelerate.
