Milky Way Galaxy – Expansion is Everything
                       Ronnie Coleinger
 
Since the first moment of our universe’s creation – a millisecond after the Big Bang, our universe has been steadily expanding. With that expansion comes a steady increase in the rate of that expansion. Everything within our universe is getting farther and farther apart as time marches on.

Whether our God caused the Big Bang and began the universe as we now know it or whether God’s work as explained in our bibles only applies to the solar system and heavens where planet Earth is located is a topic for debate. I will let the biblical scholars hash that one out.

Where was I? Oh, yes. We were discussing why objects in spare are expanding after the Big Bang. It is believed that the expansion and the increased rate of expansion is due to a force in nature dubbed, Dark Matter. Problem is, our scientists have no idea the true nature of Dark Matter. We don’t where it exists or what it is. The scientists believe it may consist of particles. It could be simply cold static particles that just take up space or possibly, high energy hot particles. What the scholars do agree on is that Dark Matter was created just after the expansion of the Big Bang.

Why am I boring you with all this information about expansion and Dark Matter? Because the astrophysics have discovered a very interesting fact about the expansion of the Milky Way and its partner, the Andromeda Galaxy.

The very smart scientists have figured out how to measure the speed of our universe’s expansion to a high level of accuracy. Just recently, it was announced that The Milky Way Galaxy and its companion, the Andromeda Galaxy are expanding at a faster rate than the rest of the objects in the universe. The reason is very difficult to understand, but simply boils down to the fact that a large void area in space is providing a push to the galaxies, causing them to move faster than the typical expansion force provided by the Big Bang.

I realize that I have not given you much detail about this topic, but I, not being a scientist, will not attempt to go into any more detail. I will tell you this, I will not forget the information I have read. I intend to write at least a full novel on this subject. The research will do me good and keep this elderly mind of mine for acquiring Alzheimer’s disease.

I have provided a link to this topic. The link comes from a very good writer from CNN. Ample detail is given so you can understand the subject material without being drowned in scientific jargon. The link is provided below:

 The Black Hole in the center of our galaxy:

 If you look up into the dark night sky near the edge of the Sagittarius and Scorpius Constellations, you are looking towards the very center of our galaxy. There, exists a spot where our scientists have discovered a very small and compact astronomical radio source. That radio source is believed to be the place where our galaxies supermassive black hole exists. That radio source goes by the name of Sagittarius A.

Sagittarius A is some 26, 000 light years from planet Earth. Light travels 186,282 miles per second. If you do the math, it would take a human astronaut about 52 years to travel to the center of our galaxy at the speed of light. However, in a twenty-first century spaceship, depending on which craft you were to use, it would take somewhere around 8000 years. Yes, I said that number correctly, 8000 years. That is why it would be great if we could travel at speeds in multiples of light years, but that is not possible with today’s spacecraft.

Here is another point to consider. To the astronaut, that 8000-year trip would seem as if it was just a short trip. That is because time is measured differently for a moving object than the stationary object in the vacuum of space. Time inside the moving spaceship slows down compared to time on planet Earth. The closer to the speed of light you travel, the more time slows down. Einstein’s Theory of Relativity explains the phenomenon and he named it, time dilation. Wikipedia puts it like this: A clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer's clock. This effect arises neither from technical aspects of the clocks nor from the propagation time of signals, but from the nature of spacetime.

As it stands right now, humans will not be traveling to the center of our Milky Way Galaxy any time soon. With that said, we might figure out how to slingshot a spacecraft around a planet or two and manage speeds close to the speed of light. Einstein said that we cannot travel faster than the speed of light, however, we soon may figure out how to circle the rim of a man made black hole and pick up speed with each transition. After a few good loops around the rim, we may be able to pick up enough speed to travel faster than the speed of light. There I go off on another eBook story concept.
