Breaking News:Dark Matter mystery deepens

Scientist studying what they call Dark Matter, that mysterious force that holds the galaxies together, are bewildered because experiments have shown that Dark Matter does not conform to what computer models says it should.

I have written about Dark Matter in this blog before where I have suggested that Dark Matter is not matter at all but a mass less force like gravity.

Dark Matter,Dark Energy and Gravity

Without the force called Dark Matter the galaxies would fly apart because normal gravity cannot hold them together. But what if Dark Matter is a force like gravity working at variable intensities to enable the universe to exist. It would suggest intelligence that would control the intensity of these forces.

Building the Nest part 2

           What have we examined so far?After a few billion years of the elements smashing into each other and being tugged by gravity, we have the Earth ready for life to arrive on the scene.
            Mindless elements with no will of their own, somehow gain a will.What am I saying?Think of a rock. It is made up of many elements, it will stay in the same spot for eternity unless a external force moves it. That rock will sit there unless wind or some other collection of elements hits it.
            Life has a will of it's own. It will change direction according to it's needs. But somehow made of the same elements as the rock.Where is the connection between physics and biology?
            Next we will examine the origin of life.

Building the Nest

            I have been itching to get into the origin of life but first I want to elaborate on the environment that allowed life to flourish.
            10 billion years after the Big bang, our Solar System,which is our sun and the other planets, began to form from the collapse of a giant molecular cloud made up of mostly hydrogen. See " A Smoking Gun).This happened in the outer reaches of our galaxy, The Milky Way.
http://www.godandscience.org/images/spiralgalaxym81.jpg
            Lucky for us, our Solar System's location,within the galaxy,is a factor in the origin of life on Earth. Our Solar System rotates at the same speed of the spiral arms of the galaxy and rarely passes thru them.This means our solar system is not too close to the other stars and not affected by the intense radiation from supernovas, stars blowing up.
            Of the planets in our Solar System, only Earth has the proper environment for life to thrive. The Earth is the 3rd planet from the sun and Venus,the 2nd planet from the sun, has been called our sister planet.This is because the mass, density and volume are similar.The similarity ends there.
             Venus has no surface water and a toxic heavy atmosphere made up of almost entirely of carbon dioxide and clouds of sulphuric acid. This causes a catastrophic greenhouse affect as sunlight is trapped and cannot radiate back into space.Yet,this deadly hell is the most beautiful object when looking up at the early evening sky.
              Mars,although smaller in size and mass, is the only other planet in the Solar System that could support life but it lacks a magnetic field like Earth has, that stops it's atmosphere from being stripped away by the solar wind. Recent observations have indicated that Mars may have frozen water.It is also the best bet for eventual colonization, which may become necessary in the future , to preserve life if a cosmic catastrophe would make the Earth uninhabitable.
               The other planet I want to mention is Jupiter. It is a massive gas giant dwarfing the Earth and revolves around the sun at the outer reaches of the Solar System. I want to point out that recent observations of other solar systems, show massive gas giants similar to Jupiter BUT revolve close to the star.This is important because Jupiter's tremendous gravity protects the Earth by capturing comets and asteroids from entering the inner Solar System ,inhabited by Earth,Mars,Venus and Mercury, and flings them back out into space. This action spares us from being bombarded by comets traveling through out the galaxy. Without Jupiter comets and asteroids would collide with our planet 1000 times more frequently.
                For the first 100 million years , the Earth was totally inhospitable to life. Rain was a corrosive acid and the atmosphere of sulphurous fumes were very similar to conditions on Venus.
                Lucky for us, after about 15 million years of Earth's existence, a large object the size of a planet, smashed into the Earth throwing large pieces into near space.After 100 million years these pieces coalesced and formed our moon.This event enabled the Earth to stop wobbling and settled into a stable rotation. The moon also helped create our weather and tides. Scientist have concluded that without the moon, there would be no life on Earth. None of the other inner planets,Mars,Venus and Mercury, have a satellite.
                Now we come to water,H2O,this most essential molecule made op of elements of hydrogen and oxygen.While water may exist, according to recent scientific observations,on Mars and Venus and even the Moon, the amount is minuscule compared to the amount of water on Earth.Over 70% of the Earth's surface is covered by water.The current scientific theory is that life originated in water.It is essential for life as our bodies are made of 70% water.
               Where did it come from?Why is it so plentiful on Earth but rare as diamonds in the rest of the Solar System. Currently there are Two scientific theories: 1(Water rich asteroids and comets raining down on the early Earth). 2 There was a thick blanket of hydrogen reacting with oxides in the Earth's mantle to form lakes and seas.
                To be continued in the next post.

A Star is Born!

            We have explored what is known about the "Big Bang" , which is the current scientific theory for the beginning of the Universe and the immediate few seconds after.We have examined gravity and light, which I submit is further evidence of design.
             Our next examination will be the beginning of the stars,galaxies and the basic elements.
              After the "Big Bang" the Universe was homogeneous, as the particles formed from the Bang flew out symmetrically away from each other.Now ,before I go on, let it be clear,if the sub-atomic particles continued this way the Universe would have evaporated.But  a lucky event happened or maybe intervention. Scientific observations reveal that tiny clumps of matter began to form in the early Universe. Scientist have concluded that these tiny clumps of matter started to be attracted together due to temperature differences of less than one millionth of a degree.This caused density variations, which are the seeds of all structure in the Universe, to enable our friend gravity to take over and attract gas and dust.
              In about 200 million years, there was enough matter to clump together that the temperature grew hot enough for fusion to begin and the first stars began to glow and the first element to form ,hydrogen.
              Where did that slight change in temperature,in the early Universe,originate?There is no answer to that, it just happened. Without that slight change of temperature of 1 millionth of a degree, the galaxies,stars, the earth and us would not exist.
               Chaos or design, you decide.

"Let there be light"

    Reference #1  
          The next entity that I am going to get into gives me a headache. Doing research on this subject, I found conflicting data from the scientific community.When you get into quantum physics, I don't think even scientist and physicists understand it fully. I try to interpret to make it simple enough for you to get the basic understanding of another force, like gravity, which we  all take for granted but is extremely complex.That entity is light.
           Scientist have concluded that light is made of something they call a photon.A photon, according to current scientific theory is a particle with out mass. Mass is anything that has matter, something that we can see and touch all the way to the microscopic level.It also acts as a wave and a particle.There is no other entity that has both of these qualities.To give you an example, sound travels as a wave and electricity travels like a particle. Think of a billiard ball as a particle and the ocean as wave. Scientist call this phenomena, wave-particle duality. Scientist always give mysterious forces in nature, that they don't understand ,a name.
            Think about that for a second.. Light is carried by something that doesn't exist because it is made out of nothing. Even electrons have mass, which orbit the nucleus of atoms and carry electricity.
            Light or photons,which ever term you like, travels at the universes top speed limit of 186,000 miles per second and is self propelled. Anything with matter or mass needs some kind of external force to propel it but light propels itself. How does it do that? Scientists say it is self propelled because it has no mass.That's a pretty weak explanation if you ask me. They don't know for sure and theory about light changes every fifty years or so because they have no idea.
             Finally, there is no clear explanation of where photons or light comes from or how it came into existence.It is just there to use as we see fit.
\             More evidence, I say, of intelligence.

Review

           In reviewing, lets take a look at the evidence so far. We have discovered that the Universe had a beginning.This is significant because it was produced out of nothing, it is as simple as that.There are several scientific theories as to what may have caused it, but because of political correctness ,within the scientific community,nowhere in scientific reports is it even mentioned that some kind of intelligent intervention may be involved. I understand there is no direct evidence of some kind of intelligent intervention but neither is there evidence of current scientific theory.
          The growth and survival of the universe shows evidence of intervention.Gravity and other forces working smoothly and flawlessly for billions of years starting with the Big bang.
           If you reject Intelligent Design, then you have to accept the other choice which is Chaos.Every time science opens one door to the secrets of the universe, they find ten more closed doors. The more they discover, the more they discover they don't know.What they do discover is the tremendous complexity of the universe starting with the Big Bang all the way to the creation of life.Could such complexity just be a lucky set of circumstances within a mindless, chaotic universe,everything happening perfectly all by itself?
          What or who causes these interventions, I have no idea. I think it is helpful, in considering Intelligent Design,to forget about an old man with a beard.Most believers in Chaos or atheist use the bible as proof, to them ,that we are just an accident of nature ,because it seems to contradict current scientific knowledge.The bible is written in metaphor, so the people of the time could understand.Much easier to say"Let there Be Light, then to write a volume on Quantum Physics.

Gravity,Dark Matter and Dark Energy

Reference to Dark Matter
            We have covered the common but mysterious force, gravity.There are two more mysterious forces related to gravity.Scientist believe they exist, even though they can't be seen or detected, because of their effect on galaxies and the universe as a whole.
            Dark Matter: Recent observations by scientists has led them to believe there must be way more mass or matter in the galaxies because the known mass that we can see and detect,does not account for the rotational speed of the galaxies or their velocity in clusters.
             In other words, all the matter that can be seen or detected is not enough to keep the galaxies from flying apart.Something else is holding the galaxies together.Scientists are baffled by this phenomena. So they have concluded that there must be something else, that can't be seen and gives off no radiation.. They have concluded that this mysterious dark matter exists because of the gravitational pull it exerts on normal stars and galaxies.They have given this invisible and undetectable force a name: Dark Matter.
            Dark Energy:When studying the universe over the last fifty tears, scientist have concluded that the universe is not only still expanding, but the expansion is accelerating.Nothing that is known accounts for this, as there is nothing but empty space between the galaxies.What is causing this repulsive force that is forcing the outer galaxies of the universe to rush away from each other.Scientist have no idea but have given this force a name: Dark Energy.
            Scientist have separated these forces that react with matter,gravity,dark matter and dark energy. Why are they separated?All three interact with matter but in different ways.What if  they are the same force?What if gravity can change it's strength according to the task it wants to accomplish.  Think of an engine in a car.It powers the wheels, the air conditioner and it generatesw it's own power. Three seperate tasks performed by a single entity.I know, this goes against Einstein's theory of relativity. But maybe gravity is more complex than first thought.
           So, what can we conclude from this?Strange forces ,that cannot be seen or detected with our most advanced  scientific instruments, determines the shape,size and the very existence of the universe we inhabit.
            More evidence that these forces are controlled by a higher intelligence. If it was just random, why does it work perfectly?
             What if dark matter interacted with the earth? We would be crushed. What if dark energy interacted with the earth? We would be torn apart.
            This is further evidence that the universe is not ruled by chaos but by intelligent design. How can it be , that these undetectable , mysterious forces which  work with such precision exist for our benefit by a lucky chance?
             Think about it, these forces have a purpose.

The force that keeps us together.

So far ,we have covered the beginning of the universe with the "Big Bang" and what happened a few seconds after the Big Bang.
                 After the initial bang ,a mysterious force intervened which became vital for the creation of the galaxies, the stars , the earth and us. A force common in our everyday life and without it, space and time would cease to exist and us along with it. Scientist don't know if it was created during the Big Bang or existed before. We call it gravity.
                 Gravity, an attractive force that always acts between particles of matter. It is stable and predictable, it is invisible. We know it exists because of it's effect on everything. You cannot shield yourself from it and it's power can penetrate anything even across the entire universe.
                 Scientist have concluded that if gravity was just a little bit stronger or weaker the universe could not support life or even exist. It is just perfect for us.
                  Another piece of evidence of design in nature or just a lucky chance of this force originating out of Chaos, you have to think about that. It is impossible to calculate the odds that one throw of the dice would produce this perfect and powerful force of nature.
                  To be honest, scientist have many theories to try to explain this, such as: multiple universes, where there are trillions of universes that pop in and out of existence and we are the lucky one in a trillion that blossomed.
                  So far, there is no evidence of multiple universes.There is only evidence of one, ours.
