I asked questions to the Time and Space(11)

The astronomy told that the Big Bang is the beginning of everything:time, space and the construction of the elementary blocks of matter in the universe.The Great Cosmic Clock started 13 billion years ago in a ball of fire so concentrated that matter and ani-matter were created spontaneously from the energy. Then it began to expand and cool down, which it continues to do today.

But I wonder that anything that exists need a space to be where it should be.So don’t we see the Big Bang as something?Is it an energy(an enormous energy)?If space is not there,time is not there,where could it be?

And it said also that the pre-Big Bang does not exist because the time does not exist.But time and space have always been intimately linked in what Einstein called the space-time continuum:

Where there is time, there is space.So when the space was created,the time began to flow.

If the present Universe came from the previous one,So the first of all,came from what? an energy too? But this first energy,where did it come from?and why?

Martin Heidegger a German philosopher of 20th century asked a question related to the beginning of the Univerese as the following:why is there something rather than nothing? But at the beginning,there was nothing?If so,there will be always nothing until now!”Nothing” cannot create something!To his question,the answer is that there is always something in the universe forever,and even the immaterial things (that are infinte and are not in space-time) exist independantly of time and space. And as they did not exist in space and time,they have no beginning nor end.So,the first Big Bang should came from the outside because there was no inside!

I asked questions to the Time and Space(10)

Plato compares the well-functioning soul to an ideal society or a state that has three parts or classes : (1) the philosopher king who governs the society; (2) the guardians who keep order and defend the society (3) the ordinary citizens,farmers,merchants and craftworkers who provide the society material needs.The philosopher king represents the intellect,the guardians represent the will and the ordinary citizens the appetite.Plato’s ideal society resembles a well-functioning soul because the philosopher king controls the citizens with the aid of the guardians.

Plato believed that the soul is immortal and eternal : when the body dies and disintegrates,the soul continues to live forever.After the death of the body,the soul migrates to what he called the realm of the pure forms. There it exists without a body,contemplating the forms.After a time,the soul is reincarnated in another body and returns to the world.But the reincarnated soul retains a dim recollection of the realm of forms and yearns for it.If the soul could avoid the reincarnation( thus avoid the sufferings),that’s because it has a chance(the last) to go to exist forever in the realm of pure forms.Plato argued that people fall in love because they recognize in the beauty of their beloved the ideal form of beauty that they dimly remember and seek.The soul experienced in the realm of forms before being reincarnated in another body to return to the world. Plato argued that learning consists of recalling what the soul experienced in the realm of forms.

The forms,unlike living organisms,are not born and do not die.Unlike stars and atoms,they do not move about in space.Unlike the familiar physical objects that surround us,they do not get hot or cold,large or smaller and so on.So,the forms are not changing objecst .They are immutable and immortal and exist independantly of our apprehending them.They do not need us to exist.For that reason,the soul loves them and yearns for them.that’s why the soul thinks or reasons in order to recall all the forms that it contemplated in the realm of forms and thus to perfect itself.

And also we have the reason why the soul falls in love of pure forms that are incorruptible and exist as the good, the just and the beautiful.As a matter of fact,nobody does not love the good,the just and the beautiful.Anyone who loves them,will yearn for them.And in yearning for them,he will search for them.But in searching for them,he need to think or to reason first.By thinking or reasoning,he can find the truth and to perfect himself with vision of the good,the just and the beautiful so that finally he can return to the world of the truth

This world or Universe,according to the Hindusim,is only the shadow of the truth.

I asked questions to the Time and Space(9)

In addition,individual things only imperfectly approximate their forms,which remain unattainable models of perfection.Circular objects or beautiful objects are never perfectly circular or perfectly beautiful.The only perfectly circular is the form of circularity itself,and the only perfectly beautiful thing is the form of beauty.

Plato concluded that these unchanging and perfect form cannot be part of everyday world,which is changing and imperfect.Forms exist neither in Space nor Time.They can be known only by the intellect,not by the senses.

So it is clear that everything that can be known by the senses is only in this visible(material) world.Our body can be known by the senses whereas our soul cannot be known by them.The soul joins with the body ,but is not chained up in the Space-Time as the body.The soul has a nature different from the body because the soul is immaterial..The body changes but the soul does not.That’s why the soul was generally described as immortal and eternal being who thinks whereas the body does not.The body is attached to the material needs but it is dominated and commanded by the soul whose function is to reason(think).

Plato divided the soul into three parts :(1 )the rational part or intellect ;(2)the will and (3) the appetite or desire.

We know the soul has these parts,because they sometimes conflict with each other; for example a person may desire something but fights with the desire with the power of the will.In a properly functioning soul,the intellect (the highest part) should control the appetite (the lowest part) with the aid of the will.

I asked questions to the Time and Space ( 8 )

(In this Universe,anything that has a beginning will have an end)

But is there something that has no beginning and no end?we knew that according to the theory of Big Bang,you Time and Space had a beginning and will have an end.So do everything that was born from the Big Bang. But an idea(form)which came from thinking substance(the Soul) is immaterial and thus should have no beginning,no end.For example the forms of circle or triangle have no beginning,no end,So do their properties such as the sum of the three angles of a triangle=180 degree.Forms or ideas are in an immutable,ideal and perfect world(Realm of forms).They are the model of all that exist.

To understand more about the realm of forms,we study Plato’s theory of forms.

Plato was interested in the form of objects : how can we apply a single word or concept to many different things?For example how can the word table be used for all the individual objects that are table? Plato answered that various things can be called by the same name because they have something in common.He called this common factor the thing’s form or idea.

Acoording to Plato,the real nature of any individual thing depends on the form in which it ” participates”.For example a certain object is a triangle because it participates in the form of triangularity.A particular table is what ti is because it participates in the form of the table.

Plato insisted that the forms differ greatly from the ordinary things that we see around us.Ordinary things change,but their form do not .A particular triangle may be altered in size or shape,but the form of triangularity can never change.

I asked questions to the Time and Space(7)

It is believed that all things must have a beginning.But Should they have an end too? Yes? and if so this Universe had a beginning and will have an end too.Its beginning as scientist thought as the Big Bang will have an end as a Big Crunch.But this is only an hypothesis or a theory,not necessarily a truth.

Yes it is believed that all things must have a beginning.So you,Time and Space too have a beginning because both of you are stuck with all things.But I wonder what is there before your beginning,your birth?Did you exist before the beginning of this Universe?Where were both of you?Time,where were you? and Space where were you?Nothing?Is it just a deep sleep without dream?

an object that exists needs a space to be where it should be,so began existing the time.If space was gone,where can it be ?And as the stronomer Carl Sagan said that Space and Time cannot be separated from each other,if Space was gone,Time was gone too!So all things in both of you will be gone too.

So can I be sure that both of you had a beginning or are you infinite which means that you have no beginning then will have no end?And Is this Universe is the only one.But many astronomers believe that there are other Universes with different histories of Time and Space and different physical laws without thinking of the exsitence of invisible Universes.

I asked questions to the Time and Space(6)

The black holes are the most bizarre objects in the Universe.And that is because they emit no visible light and they have a very strong force of attraction that swallow everything including light near their region.That is why they were called black holes.Today the astronomers are sure about their existence.They even have taken a photo of a black hole (from telescope)at the center of Galaxy Milky Way several years ago.

The black hole came from a dying massive star that finished its life in a supernova,an explosion that became extremely brilliant and shines more than an entire galaxy during several days.And it is possible to see the incandescent rests of the star that died hundreds or thousands of years ago.

When a supernova exploded,the core of the star collapses and becomes in general a neutron star,but not always.If the burning core that collapses is heavier than 3 masses of the sun,the very tight neutrons cannot struggle against its gravity.So the star becomes a black hole.

The neutron star a very super dense object that has the same mass of the sun confined in an area smaller than the city of New York.

The mass of the black hole can be big or small.Some black holes have a mass equal to millions or even billions of the mass of the sun.But these massive black holes hide at the center of galaxies.They do not come from the supernova but from the collapse of the gigantic clouds.

And some astronomers believe that tiny black holes exist too.These tiny black holes were created by the forces of the Big Bang.They have the size of the atom but have the mass of billions of tons.

I asked questions to the Time and Space(4)

In the picture below,the spacetime is represented in the form of a rubber mattress.The heavy masses deform it : that’s the principle of the relativity.

Albetr Einstein(1879-1955) is the inventor of the concept space-time and the father of the theory of general relativity that finds a perfect illustration with the black holes.A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape it.

At the regions near the big masses,the spacetime is neatly curved.This curve influences the movement of the smaller masses.It influences also the time.Unable to verify this truth,Einstein thought that the gravity could slow down the time.

In 1960,five years after his death,an extremely precise clock was invented.It verified the hypothesis of Einstein : at the top of a skyscraper,a clock beats faster than at the ground floor where it is greatly influenced and curved by the gravity.

On the rubber mattress,imagine a small ball but extremely heavy : it pull down the mattress to the bottomless bottom(infinite).That make a black hole which is in an extremely powerful rotation that can swallow everything (including light) around its region.

According to the theory of general relativity,the gravity slows down the time.This means that in a spaceship launched at a very high speed(to escape from the gravity of the earth),the time passes slower.So,if an astronaut travels in a spaceship launched at the speed of light,can surely come back to hug his great great grand-children.That shall be wonderful!But unfortunately we cannot build any spaceship that can travel at the speed of light.Even it is possible,can man travel in it at the speed of light?But the Einstein’s equation : E=mc^2 told that man cannot travel at the speed of light.
