What's out there in the vastness of space.

Have you ever looked up into the star studded sky at night and wondered what was out there.  In the photo by NASA's Hubble, taken of a small section of sky that appears to be empty to the naked eye, revealed no less than 10,000 Galaxies.   When you consider that our own Milky Way Galaxy, is 100,000 light years in diameter, then this photo adds a whole new dimension to our thinking.  If we could travel at the speed of light, 186,000 miles per second, then it would take us 100,000 years to travel from edge to edge of the Milky Way.  

Forget about visiting our nearest neighbor galaxy, Andromeda, which is 2.5 million light years away.  At present, a journey to Pluto, which is at the extremity of our Solar System, would take about 23 years and 100 day's, in a Space Shuttle.  Unless there really is a "star gate".  Smile. 

I realize I am going to be treading on some traditional toes, but the idea that all of this started with a big bang is amazing to me.  The theory states that a big explosion happened several billion years ago and out of it came the universe with billions of stars, planets and galaxies. All this structure and organization from an explosion.  Usually an explosion causes disorder and destruction, but planets and suns are round.  Hard to believe they were the result of an explosion.  On the other hand, meteors are jagged and odd shaped, because they are the remnants of planet collisions and explosions. Go figure. 

The orbit of the Earth round the sun, gives us a 24 hour day and a 365 day year.   The sun and moon's gravitational pull, control Earth's ocean tides and weather patterns.   Gravity prevents the atmosphere from being sucked into the vacuum of space. Earth's atmosphere is in two sections.  The lower part, called the Troposphere and is 6 to 10 miles high which is our breathable air and where all of Earth's weather happens.   The upper atmosphere is called the Stratosphere, and is 5 to 8 miles high and contains the Ozone layer, which filters harmful solar radiation like UV rays.  It is formed from the action of Solar Radiation on the Oxygen in the Stratosphere.  Without the Ozone layer, we would all die from skin cancer.  Is this the result of a Big Bang? ... Amazing. 

How could such detail come out of a chaotic explosion.  This explosion suddenly created all the laws of science and physics, that allows us to calculate the trajectory of a space craft for an eight month journey to Mars, and land a one ton vehicle gently on it's surface, within a 20 mile radius.  See NASA's Curiosity

The explosion resulted in the formation of atoms with their central nucleus of protons and neutrons and the orbiting electrons, so tiny that we need an electron microscope to view them.  The protons and neutrons are made up of combinations of quarks and gluons.  Not to mention the neutrino, which has almost zero mass, and is so small, it can pass through a block of lead without touching any atoms.  

The theory suggests that this Big Bang had enough material to create the billions of stars, planets and dust contained in the millions of galaxies, some of which are shown in the photo above.   It does not make sense to me. Is there a scientist that can explain this to me? Please.

There are so many educated people who believe all this was a cosmic accident.   The universe is so ordered and structured, that if the Big Bang is correct, it must have been started by someone highly intelligent and powerful.  Could that be God almighty.  The creation now sounds plausible ... right?
