There is an electromagnetic spectrum that encompasses all waves from ultra-short to long waves.
The visible part ( for human beings) is only a small part of it.
Your image comes as a bundle of visible electromagnetic waves to the eyes.
Inside the eyes is the retina and the retina-cells receive those
waves and change those into electric pulses and send those through the
optic nerve (nervus opticus) to that part inside the brain where "seeing" is determined .
In that part of the brain those pulses are transformed into neurochemical and neurophysical activities and then I "see" you.
But until this day there hasn't been a single neurophysiologist who has found the precise formula of the how and what then exactly goes on in the human brain and how that transformation of electromagnetic waves into neurochemical and neurophysical activities results in "seeing" your image.
Like there has never been a neurosurgeon who sawed open a skull and seen or found or observed in the brain the "mind" or the "soul".
Is there the mind?
The human genome
Every human beings exists of cells.
Desoxyribonucleic Acid model
The DNA contains all genetic information of a human being.
And those cells contain the DNA (desoxyribonucleic acid).
In the human cell is a nucleus.
Inside that nucleus are 23 pairs of chromosomes.
Those chromosomes also contain the genes, these are the basic units of heredity.
If you chart all these, then in principle you have the blueprint of a human being.
A genome is the complete collection of the genetic material of an organism.
So of the human being it is called the human genome .
Under supervision of the English chemist Frederick Sanger,
a project was started what was called the "Human Genome Project" and in 2001 a concept genetic blueprint was published.
The scientists themselves think that this "Human Genome Project" will cause a revolution in medicine.
But there are also numerous ethical, legal and social consequences attached to it.
About this you can contemplate.
Our place in the universe
You are standing somewhere on the surface of earth.
The earth is only one of the planets in this solar system.
The planets rotate around the sun.
The sun is only a middle sized star which is located in a spiral arm of a spiral galaxy.
position of the sun in a spiral arm in our spiral galaxy
This spiral galaxy is only one sort of galaxy of multiple sorts of galaxies
that are located in groups or clusters in the universe.
Those clusters are moving, like everything is moving, away from each other.
Cluster of galaxies
Our solar system contains the earth which has life within the atmosphere
There are at least countless stars in our galaxy that are comparable to our sun and perhaps that there are also planets there similar like the earth.
One of those might be the exoplanet Gliese 581.
Comparable size of exo-planet Gliese 581
They may also have life of whatever kind
Discovering the universe
Human Beings did always want to know how the universe works.
You look through a telescope to a star
The star that you see you do not see like it is now.
Light has a finite and specific speed and the light of the star you are looking at has probably travelled for millions of years before it was absorbed by your eyes and processed.
You see the star.
But in fact you see how it looked millions of years ago.
You don't see the now but the past.
People build enormous telescopes on top of mountains
(Observatory in Chile)
or send a large space-telescope like the Hubble Space Telescope in an orbit around the earth.
There are radio-telescopes being built that capture and register and process the radio-waves from space.
(VLA Very Large Array radio-telescope in New Mexico, USA)
Space-probes like the Voyager I are being send into space to make photo's of our planets and perform measurements and send all that data back to earth.
After that the probe will leave the solar system on it's way to another solar system.
We will not experience that anymore.
By that time we'll be long time dead
(Voyager I space-probe and the disc with information about planet earth)
That's how people try to obtain an image of the universe with all sorts of means and observational instruments. All the information that is obtained from all those observational instruments is used by scientists to substantiate their theories or just to develop new theories.
The origin of life
A cosmologist i.e. develops theories about the construction and nature of the universe.
Was it always like this?
That's what the followers of the Steady-State theory say.
Was there at first a primeval explosion or a "Big Bang" and moved everything away from one another after that and was everything so formed in the course of time?
At first gaseous clouds,

Then the solar systems with the planets around a star
then a planet around which an atmosphere forms
and where on the surface in a sort of primeval soup the first life is formed.
From non-living (an-organic) chemical elements living (organic) creatures are formed.

No, something totally different was going on and had happened.
Live had slowly evolved which must have taken millions of years.

And to confirm all that people dig in deserts and in mountains and valleys for remains from the history of all life on the earth.
Fossil plants and animals are dug up.
They are dated with the help of modern equipment.
Because we want to know how old they really are.
Large skeletons of dinosaurs are dug up and displayed in museums.
The skulls of humanoid apes are dug up.

Large detection devices are build that must investigate how elementary particles are formed and how they relate to the four fundamental forces in nature.
Experiments take place to find proof of the existence of certain types of fundamental elementary particles such as the Higgs-boson.
The atoms, the electrons, the neutrons, the gravitons, the quarks, the bosons, the mesons, etc.
It are some concepts that are used in the world of elementary particle physics.
(simple atom representation; atom is formed by a nucleus and electrons
moving around the nucleus; the nucleus is formed by protons and
neutrons; the number of protons equals the number of neutrons in the nucleus except for the hydrogen atom which has 1 proton)

The scientists build particle accelerators such as cyclotrons, synchrotrons, etc.
It are particle accelerators that accelerate electrical particles and then lead them to a detection device wherewith “photos” or computer simulated data models are made of the "collisions" of the various particles.
The particles themselves you do not see.
You see the traces of those elementary particles.
The idea is to find proof for the theories of theoretical scientists.
Theoretical physicists have developed theories based on mathematics and known physics about elementary particles and how they relate to the four fundamental forces.
This is important for an understanding of the origin and evolution of matter and the universe as from the Big Bang when the universe is believed to have originated.
For instance are they looking for a specific elementary particle ,the so-called Higgs-Boson or also called the “God-particle”.
These theories, if proven, can change the view scientists may have on for instance the origin of the universe like in the “Big Bang” .
You can see them as sort of “laboratories” or gigantic “microscopes”.
For example at the European Centre for Nuclear Research - CERN at Geneva in Suisse (Switzerland) where the largest particle accelerator in the world was built.
It’s the Large Hadron Collider ( LHC) and it’s 27 kilometres long and 175 meters deep.
It’s runs underground partly in France and partly in Switzerland.

You get up , you go to bed
You sleep , you eat, you work,
you get an education .
You take care of your children you work hard for
Money to earn for the rent of your house
or the instalments of your debts, you live your old age in an
old people's home .

In short: you are a human being in this life.
Every human being has a different life.
Why should you worry about affairs that do not touch your daily life?
Nobody has practical benefits from astronomy, from theories of modern cosmology, from theories about elementary particles from theoretical physics.
Those theories do not pay for your rent, they don't buy food for your children, they don't end your daily worries.
You awaken and look up.
The sun rises, and the sun sets.
But just that is not true.
The sun doesn't rise and the sun doesn't set.
It is the earth that rotates around it's own axis.
That's why it looks like the sun rises and the sun sets.
The truth of your perception is not the truth of what really happens.
What you see is not always what is real.
It is always worth to think about more than only the everyday reality.
Even if that reality of your everyday life sometimes occupies and swallows you up so badly.
The following piece comes from a book called Herzog by the American writer
Saul Bellow :
"So, thought Herzog, acknowledging that his imagination of the universe was elementary, the novae bursting and the worlds coming into being, the invisible magnetic spokes by means of which bodies kept one another in orbit.
Astronomers made it all sound as though the gases were shaken up inside a flask.
Then after many billions of years, light-years, this childlike but far from innocent creature, a straw hat on his head, and a heart in his breast, part pure, part wicked, who would try to form his own shaky picture of this magnificent web".
