Edwin Hubble, a Pioneer in Modern Astronomy

Who Was Edwin Hubble

There was a time when man thought that the earth was the center of the universe, but less than 100 years ago, men thought that our galaxy was all there was to the universe. The man credited with the discovery that the universe was much larger, and in fact expanding all the time, was an American astronomer by the name of Edwin Hubble. Hubble was born on20th of November in 1889 in Marshfield, Mo, the son of a lawyer.

As a teenager, Hubble was very active in sports, but he obviously had no idea of what he wanted to be. He received a scholarship to the University of Chicago, where he had decided to go into law, but due to an administrative error he had to share the scholarship with another student causing him to have to tutor and work summer jobs to fill in for the balance. He worked as a lab assistant to Robert Millikan and got a scholarship in physics.  While in College he participated in track & field, boxing and basketball. He Graduated in 1910 and was awarded a Rhodes Scholarship to Queens College in Oxford. He returned to the US in 1913 and passed the bar exam. He practiced law for only a short time before he returned to the University of Chicago where he got his doctorate in Astronomy.

Upon completing his Doctorate in 1917 he enlisted in the army and served in France during WWI.  After the War G.E. Hale, the well known American Astronomer' offered him a position at the Mt Wilson Observatory in California where he stayed, except for a period during WWII, for the rest of his life.  In 1923 he determined that the Andromeda Nebulae was about 900,000 light years away putting it outside of our galaxy, which up until that time was thought to be the only galaxy. This opened the door to the realization that the Universe was far larger than the accepted idea of the time.

Soon after astronomer Edwin Hubble proved the universe was expanding, it became evident that the universe was once very much smaller. The theory that the universe started from a single point (or very small area) is known as the big bang theory. The big bang theory has caused scientists to suggest that this universe would keep on expanding and creating by itself.

The reason why astronomer Edwin Hubble claimed that he discovered the universe was expanding was merely due to he discovered that the galaxies were moving further away from this earth at higher speeds, proportional to their distance and from then, he jumped into the conclusion that the universe was expanding.

However, there are a few reasons that are listed out below to show that it is irrational to jump into the conclusion that the universe is expanding by seeing the galaxies were moving with higher speeds further away from the earth:

a) Let’s visualize that you are standing at a point where the earth rotates around the sun. As the earth makes a half round turn towards the point that is opposite to you, certainly you would express that the earth is moving far away from you. Let’s assume that you do not know that the earth simply rotates around the sun in a complete turn and what you have seen initially was simply its moving away from you right to the point that is opposite than you. Could you jump into the conclusion that the universe is expanding simply due to you see the earth moving far away from you? Surely you cannot jump into this conclusion since the earth would spend about 182 days to rotate from the point that is opposite than you to the ultimate place where you stand to visualize and focus on its movement.

The same thing happened to the astronomer Edwin Hubble. He could not jump into the conclusion that the universe was expanding by seeing that galaxies were moving further away from this earth at higher speed since they could be a possibility that the galaxies would make a round turn after numerous days or months or years later. Thus, the assumption that the earth could be expanding by seeing galaxies were moving further away from this earth was simply some kind of speculation.

By the way the earth rotates around the sun by 365 days, how do you know the galaxies might rotate themselves around with years due to vast space of this universe? Edwin Hubble jumped into the conclusion that the galaxies would be expanding by observing and comparing the galaxies within a few days in his span of life is insufficient or rather speculative. This is due to how we would know that some galaxies might take more than a hundred years to make a full turn since this universe is in a vast space.

b) The earth is just small as comparative as the whole universe. To visualize from a small end, the earth, to the whole universe so as to jump into the conclusion is rather full of speculation. This is due to Edwin Hubble does not know how the universe looks like whether it looks like a sphere with boundary beyond. He also could not even be able to visualize what goes beyond the boundary. If there is a boundary that is beyond this universe, what substances that would be formed to restrict the space of universe? Could this boundary be stretchable or expandable? What if the boundary of this universe is not stretchable, the whole universe would be kept within it? If the boundary of this universe is not stretchable, how could the universe be expanding? Are there matters that go beyond the boundary of this universe? As Edwin Hubble saw the movement of the galaxies from the small little earth without the overview of the universe, his conclusion is full of speculation. Thus, it is irrational to jump into the conclusion that the universe is expanding simply by seeing that the galaxies were moving away from his sight while staring at the galaxies on earth.

.

c) There could be a possibility that this whole universe could be as a sphere and that all planets, moon and etc. could be rotating round and round within the sphere. It could be that the galaxies that Edwin Hubble was observing were moving faster speed than our galaxies. As the moving speed of another group of galaxies was faster than us, it seems to be that its moving away from our earth with fast speed. However, that group of galaxies might indeed perform its routine movement to turn round and round just that its speed is faster than the speed of our galaxies. Despite that galaxies might have moved faster than our galaxies, it still moves round and round within the big boundary of this whole universe. If that is so, it is irrational to use it to jump into the conclusion that the universe is expanding simply by seeing that the galaxies were moving away from his sight while staring at and comparing it while he was on earth.

Thus, using the evidence from Edwin Hubble to jump into the conclusion that the universe is expanding is rather speculation. As it is speculation, it is irrational to use it to support that Big Bang theory.

Valid points one and all. There is absolutely nothing in science that is not speculation. I was so upset when I realized as a 14 year old kid that the things that were being taught as facts were not only theories but they weren't even the most accepted theories in the scientific community. This was nuclear physics but most science is like this.

Edwin Hubble mentioned that the universe is expanding by observing the existence of many red-shifts appear in the galaxies is itself an assumption. One might argue that the universe is not a sphere and that we have no proved to deny it since nobody in this earth did see the boundary of the universe. Some might assume that there is no ‘empty place’ in the universe into which matter expands. If that is true that there is no ‘empty place’ in the universe into which matter expands, questions have to be raised due to the uncertainty about what would go beyond the matter in which the universe itself is expanding: What materials could it be that would make up of that materials? Nobody in this world has ever seen in the past whether there could be any matter that covers the universe. So, nobody in this world would know whether the matter could be stretchable or non-stretchable. What if the matter that covers the universe is not stretchable, how could the assumption that the universe could be expanding to be true? By the way, as nobody could see that there could any matter that covers the universe and this includes Edwin Hubble. His theory that the universe is expanding by observing many red-shifts in the galaxies is just some kind of speculation. If there could be matter beyond the matter, how big could the matter be? Could there be anything or any other universe or anything that is beyond this universe that could block the expansion of this universe in many years later? What could that matter be made up of so much so that it could allow this universe to be expandable? If that could be some matter that covers this expanding, could the thickness of this matter be lasted into infinity? If there could be a matter that covers this universe, could this matter be breakable since the support that the continuous expanding of this universe is true? Would there be any substance after the matter that covers the universe that could be expanding? As there are many uncertainties about this universe and whether there could be any matter that covers this universe since nobody could have a full sight of this entire universe, Edwin Hubble jumps into the conclusion that this universe is expanding by seeing many red-shifts in the galaxies is a little speculation unless he could be certain that there were people in the past did see the matter that would cover the universe so as to make this conclusion. Or else, there could be a possibility that this universe might be lasted until infinity without any matter covering this universe.

Edwin Hubble’s theory does not provide any support for the Big Bang’s theory since his theory involves speculation since we do not have the full sight of how this entire universe could look like.

Is it true to mention that there is no blue shift in this universe? The following are the websites addresses in which you could locate evidences that there are blue shifts in the galaxies to disprove the argument:

http://ned.ipac.caltech.edu/cgi-bin/nph-allsky?ra_...

http://www.beskeen.com/gallery/galaxy/m31/m31.shtm...

The following are the possible reasons for the above blue shifts to arise:

a) This universe could have an immense space in which it might take more than 12 billion light years or even trillion light years to travel from one end of the universe to another initially. These galaxies might have travelled more than a half round in their usual routine tracks of rotation to its return and that there could be a possibility that there were a period of long time and that could be more than 12 billion light years ago that most of the galaxies might be in blue shift. As some of the galaxies are advancing slower than majority of the galaxies, it turns up that majority might have completed their full turn and moving upward and advancing further away from us and leaving a few galaxies to be in blue shift currently. As nobody could see the universe as a whole from the very past, especially what was beyond 12 billion light years ago or even trillion years ago, there could be such a possibility to occur in this universe. To jump into the conclusion that this universe is expanding simply by seeing many red shift is rather speculative.

b) There could be a reason in which that all the galaxies might have travelled faster than the above-mentioned galaxies bypass our galaxies in numerous years ago and ultimately causes these galaxies to fall behind due to their rotating speed is slowly than most of the galaxies. This assumption includes the possibility that there could be many blue shifts in numerous years ago and that could be beyond 12 billion light years ago, as the galaxies were travelling a rapid speed toward us. As most of the galaxies have bypassed our galaxies in the past and at the same time they have completed a full turn from its rotation, these certainly result in many red-shifts in current world due to most of the galaxies have moved upward following its usual movement tracks for its half turn of its rotation. As a result, this causes us to have more red-shifts than blue currently.

Most of the galaxies might not pass through us to be the centre of the point for rotating. However, it could be the possibility that most of the galaxies could have bypassed us in numerous years ago and this could be the reason to have the result in many red shifts than blue currently.

As some of the galaxies were moving slower than most of the galaxies, this results that there are more red-shifts than blue currently.

c) There could be a reason that some galaxies are moving fastest speed than the other and this causes some galaxies to be in blue shift since they have completed a half round turn in facing our universe in advancing.

d)There could be many other possible reasons that we could think of for the possibilities to have more red-shifts than blue currently and that does not come to the conclusion that our universe is expanding or this universe could create something out of nothing.

Some might mention that the discovery of many red shift in the galaxies have moving further away in rapid speed, could provide the support of dark matter theory or Big Bang theory. However, there is a possibility that most of the galaxies might well perform their routine movement and it might not give any signal that this universe could be expanding. As most galaxies are travelling in rapid speed, this causes them to bypass us fastest than a few galaxies and this has resulted in more red shifts than blue currently.

Some might have mentioned that the observation could be through 12 billion light years old that the galaxies have been moved in all directions further away from us. However, consideration has to be taken into accounts pertaining to the size of the universe since the size of the universe could be so immense that galaxies might take more than 12 billion light years or even much longer than that, such as, a few trillion years in order for galaxies to make a half turn in rotation in order for us to have most of the galaxies to be in blue shift. As nobody could have the full view of this universe and nobody did see whether there could be a boundary of this universe, we could not reject the possibility of the vast space of this universe. Or in other words, there could be a possibility that galaxies might take more than 12 billion light years or even trillion light years in order that most of the planets could complete their half round turn so that we could have the many blue shift from the time onwards.

Nevertheless, it is too irrational to jump into the conclusion that the universe is expanding simply by observing the galaxies are advancing further away from us to conclude that our universe is expanding.
