“Questions about the Universe” by Lewis Jordan Sexton (13)

Questions about the Universe??????

Lewis, thank you very much for your thoughts and the questions in your own mind that you are thinking about. Wow.

I’m tempted to tell you a story about a question that my wife asked to her mother when she was about your age. “Mother what is the Universe and what was the big bang?” Her mother’s reply was “They are very big questions, I think your time is better spent making sure that this planet we are living on lasts as long as possible, rather than worrying about the Universe”

For readers who are interested here is the what Lewis submitted. Lewis, if you would like me to remove it send a request in the comment box below.

My thinking is that we have no idea, at the moment, whether any of the the thoughts put forward by various scientists are valid. It seems to me to be a classic case of a set of developing scientific ideas as the tools and thoughts of the the scientists develop.

For example notable scientists like Newton and Einstein developed ideas relating to your thoughts  which were effectively disproved. This is in fact the way that all scientific arguments progress. For example ……When Albert Einstein was formulating his ground-breaking theory of gravity in the early 20th Century, at a time when astronomers only really knew of the existence of our own galaxy, he used the simplifying assumption that the universe has the same properties in all its parts, and that it looks roughly the same in every direction wherever, in the Universe, an observer happens to be located. Like Sir Isaac Newton two hundred years before him, he assumed an infinite, static or “steady state” Universe, with its stars suspended  motionless in a vast void.

One of the driving forces behind the development of science thinking is to disprove earlier scientific thinking. It is called falsification.

It was a philosopher,Karl Popper who said you can only have a scientific theory if it can be proved to be false. This is what has happened to the scientific theories of Einstein and Newton. Some of their ideas/theories on gravity and the nature of the Universe have been successfully disproved. New theories by Hubble (the telescope scientist) disproved the stable Universe idea’s of Newton and Einstein. This led to new scientific ideas of an expanding (rather than a stationary static state)  Universe …which could be false? To illustrate how scientist are challenging Hubble’s ideas it is now known that the Universe is expanding at an accelerating  rate than rather than a steady rate …….the mystery continues. 

Have a look at this website The Physics of the Universe.

I shall continue thinking and possibly updating.

Thanks again for your thoughts.
