Of Course it is OK.....BUT I just think and observe.<br />
I have no credentials, other than being conscious.....most of the time.<br />
<br />
But the kids will put their "thinking caps on", and ask the question " Why?". The ultimate Human question.<br />
It is a lot easier to figure out" How". We can measure, use math, develop theorems, and make predictions based on those studies. Science is based on doubt, not certainty.<br />
It's fun to think about.<br />
Thank You, I am complimented.<br />

I have a couple of "fun" discussions: The missue of the word "like". I have figured out how it started and why it spread throughout the language of our teens and adults. "You know, like, he was like really mad." Hint: Maynard G Krebs / Frank Zappa / Valaley Girls / Scooby Do.<br />

A more serious addition the "Natural Selection and the Evolution of Species".<br />

The whole post is on the Forum. I would love to hear teacher's opinions.....Maybe Steven Hawkins would drop us a thought or two.<br />

AH! One of my favorites! I am glad you asked. This is not a PhD. opinion, just the result of a lot of thought. maybe a little reason tossed in irrationally, OF COURSE!<br />
<br />
This entire theory is based on one observation. Edwin Powell Hubble, using long exposure photograhic film, he discovered that our Milky Way Galaxy had neighbors that were Galaxies too, lots of them.

This entire theory is based on one observation. Edwin Powell Hubble, using long exposure photograhic film, he discovered that our Milky Way Galaxy had neighbors that were Galaxies too, lots of them. He also noted that the spectrum of the visible light captured, shifted toward the "red" fequency. This observation suggests, that these galaxies are moving away from the Earth. He theorized that if two masses are moving away from each other, they must have occupied the same space at one time. That makes sense.<br />
If you hit a ball with a bat, the ball is traveling away from the bat.....but what if you swing a bat and your buddy throws a ball away from you....GEE! You might think that the bat and ball were in contact.....Glad that I thought of that.<br />
<br />
After literally thousands of galaxy spectrum measurements, all demonstrating a "doppler like" shift in light frequency, the BIG BANG THEORY was born.....Now we know that there are billions of galaxies containg billions of stars...Wow that is a lot of mass!<br />
<br />
But there are observations and calculations that may contradict the BB theory.<br />
The actual Science and Math is beyond my comprehension, however this is what I understand.<br />
<br />
Astronomers have calculated that there is not enough "known" matter in the Universe to substantiate the BB theory from a gravitational perspective. To make the BB theory comply, they predicted that there must be "dark matter" throughout the Universe. Dark matter is matter that we cannot observe. They used to speculate that there were alternate Universes in different dimensions, but that didn't fly well in the face of reason. Great for Science Fiction stories though.<br />
<br />
Everytime we discover a new galaxy that is at the outer edge, we push back the estimated date of the BB. I have a small problem with that, it always coincides with the distance of the outermost galaxy. If a galaxy is determined to be 14 Billion light years away, then the BB occured 14 Billion years ago.<br />
That would imply that the relative motion of that galaxy is the speed of light...HMMMM....OH!<br />
A recent notable Phyicist explained that, at the time of the BB,,,the laws of nature did not exist.<br />
So we cannot understand how matter got where it was....."Please pass the KoolAid. our spaceship is almost here."<br />
<br />
I see a pattern here....Is the BB a Scientific Theory or an article of Faith. A Scientific Theory is a belief based upon observations, experimentation and reason. Faith is a belief based on Reason alone. The supporters of the BB have crossed the line from Science to Faith.<br />
<br />
There was one interesting Science program that I watched about a year ago. A group of scientists were attempting to lower the temperature of a gas to Absolute Zero, -270 degrees Kelvin. A temperature, at which, there is no random molecular motion. They could not reach -270, but they came within a few degrees. One of their experiments involved passing a laser beam through the gas. They observed that there was a reduction in the speed of light...OH BOY! Poor EINSTEIN! He rolled over with that discovery. So why am I relating this experiment....If a beam of light must travel for 14 Billion Years through the vastness and near "absolute zero" stillness of space...How reliable is our observation of that beam of light? I'm not sure, but that was some trip!<br />
<br />
One last little problem, the Milky Way Galaxy is predicted to collide with another neighboring Galaxy in the next billion or so years....I guess nobody told that Galaxy that it was traveling in the wrong direction....Where are those Space Police when we need them?<br />
One last note! We exist in a dynamic Universe, everything is in motion. the Earth revoles around the Sun, the Sun revolves around a "Central Point" of the Milky Way and.....What does the Milky Way revolve around????? That's a big question.<br />
<br />
Thanks Nellie, I've emptied out some brain cells...I may have even lost a pound or two.<br />

Hi Nellie,<br />
<br />
I took a moment to review a physics forum thread discussing the "is light matter" question. Needless to say, the debate rages on. I have had a few arguments. make that rude discussions, on this site. Some people worship what they have learned and mastered, they provide very strict authoritative answers, backed up with mathematical equations that apply to the observed principals in question.

Hi Nellie,<br />
<br />
I took a moment to review a physics forum thread discussing the "is light matter" question. Needless to say, the debate rages on. I have had a few arguments. make that rude discussions, on this site. Some people worship what they have learned and mastered, they provide very strict authoritative answers, backed up with mathematical equations that apply to the observed principals in question. Blinded by knowledge, perhaps. This is against my grain, I enjoy wondering "WHY?" and try not to confuse it with "HOW". I was introduced to a quote in High School, " We come to question knowledge, not to praise it." I could never determine the author of that phrase, a little twist on a line in "Julius Ceasar".<br />
My teachers were Augustinian Priests, a pretty tough, but respected group of men. I studied Biology in College and we were taught to question and verify. Our experimental design was setup to disprove our hypothesis, not support it.<br />
You have provided your students with a "Gordian Knot", The discussion may never be resolved.<br />
Let's see what the kids think....they'll teach us a thing or two.<br />
