Think I am just thinking.

Words are but thoughts made visible.

Time and Space – part 2

   I wrote a while back about some thoughts on Time and Space.  There seems to be much conflicting information regarding the true nature of the universe.  Another item which crossed my mind the other night as I lay in bed waiting for sleep to arrive, was the rate of the expansion of the universe.

  Hubble measured the expansion of the universe to be one of ever-increasing rates of speed, the farther distant you look.  I have yet to hear of a theory of why this difference in speed exists.  Well, as I was contemplating this issue, a deep dark thought occurred to me.  No, not anything evil, but rather Black Hole Theory.  When you  think about a the gravity well of a Black Hole, the concept that comes to my mind is one of a string of rubber bands.  In this case, rubber bands that start off as weak ones, followed by ever larger ones and more powerful ones as you approach the Black Hole. 

  So what does this have to do with the expansion of the universe?   First you have to think about what is beyond the boundary of the universe?  Based on much of what I have read, what is perhaps most logically to be expected is a total pure vacuum.  Not the vacuum of space as we know space outside the boundaries of the Earth, Solar System, or even the vacuum of space between the Milky Way and our neighbor the Andromeda galaxy.  For this space is anything but empty.  All the partial physicists agree that in the vacuum of space as we know if, you will find molecules abound and particles keep popping into and out of existence in the subatomic regions of space.

   Now back out to beyond the known universe, is the pure vacuum of nothingness that existed prior to the singularity, or event region between different dimensions, which Banged, or Tore itself, depending on theories, into being. 

   I think of this pure vacuum of nothingness as being the source of why the galaxies further away, are moving faster and faster the further you look.  Think of the inverse of the Black Hole effect.  as the universe expands, matter is moving farther away from each other.   This increasing distance correlates to a reduction in the force that gravity can expend between the gravity wells of the galaxies.  This would mean that the true vacuum of space outside the universe, is acting as an attraction force drawing matter ever outward at ever-increasing velocity as the force of gravity becomes weaker as matter is spread ever thinner in our expanding universe.  Thus as the force of gravity increases exponentially around a Black Hole, the force the The True Vacuum outside the boundary of the universe is having an exponential influence on the speed of the expansion of the universe as the universe thins due to expansion.  Thus, the closer the galaxy is to the edge of the universe, the faster it will move, being drawn, or pushed as it were, through a straw, from a region of high pressure of compacted matter, into and toward the low pressure region of the True Vacuum beyond the edge of the universe.

Ok, I think I can go to sleep now.

Looking back into Time.

   Once again NASA has launched a space shuttle back into space to perform life extending service to our own public “Time Machine” the Hubble.   If you have not yet logged onto http://hubblesite.org/, you really need to check it out.  Click on the Galley tab to view into the eyes of the earths best time-machine. 

   The photons of light the Hubble Telescope captures originated as far back in time as over 12.7 Billion years ago.  So we may only be able to go backward in time, but “Wow” what a backward glance it is.  The job of getting your mind around the fact that we are able to see light that is over 12 billion years old, is just as difficult as trying to start to grasp the distances being observed.  Light travels at a speed of 186,000 miles every second.   Now think about how far a photon of light can travel in just one hour.  That’s well over 6 million miles in a single minute.  Now extend this by hours, days, weeks, months, and finally a single year.  You just might be starting to grasp the distance and then we start talking about thousands, millions and then billions of years, traveling at that same 186,000 miles each and every second of those billions of years.

   These numbers are so great, that if each of us represented a single atom, and we lined up each and every single atom that makes up the earth, we are still not reaching across the cosmos.  It is extremely difficult to comprehend these type of distances.  Now that you have perhaps started to understand that we are talking about distances beyond imagination less than 100 years ago, we have thus far only talked about looking in one single direction into space.

   Now consider that we can look in every other possible single direction outside of our world and see light coming at us from these same extreme distances.  About this time you may be feeling rather small and insignificant in the cosmic universe.  Though it is true each of us does not amount to even a grain of sand on the earth, in comparison, we can each look at the images captured by Hubble and revel in the knowledge that each and every one of us is unique in this same universe. 

   So at a time when we can each perhaps feel very small indeed, we should realize that in all the universe we have yet to find other life, be it intelligent or not.  Though the odds are greatly in favor of there being life elsewhere, somewhere, we know life appears to be very rare off the planet earth.  At least we have yet to find any.  So my wish is everyone could realize how precious life is, and what a shame it is that our history is filled with our willingness to destroy what is so rare in the universe.

This is an image taken by the Hubble Telescope. 

The Hubble telescope was pointed to what was thought to be one of the most empty regions in known space.  As can be seen in this image, the Hubble time-machine was still seeing hundreds and hundreds of galaxies even as far back as almost 13 Billion years ago.  And around each of these galaxies are millions or stars with their own solar systems in an area of space which is less than a grain of sand as far as we can see.

No matter where we look, there is more to see.  What will the upgraded Hubble show us next?
