Stringing Through Multi-universes

I'm no scientist. I do hold a B.S. in Mechanical Technology - Manufacturing Systems. It's kind of misleading. The majority of my course work was in mechanical engineering. I switched because it allowed me to graduate faster. I needed to get done with school and start earning a living.

My educational background has: physics III, calculus III, differential and partial differential equations and several mechanical engineering classes like statics, dynamics, thermodynamics, mechanical design, hydrodynamics and basic electronics.

I point out my educational background as a basis to my views in science.

Now to my real topic.

Physics breaks down into two theories: Newtonian or classical and quantum. Newtonian physics deals with molecules all the way up to large bodies in the cosmos. Common equations like force = mass * acceleration and measurements like pressure all fall under Newtonian physics. At the subatomic level, Newtonian physics breaks down and quantum physics takes over.

A big quest for physicist and science in general is to establish a theory that ties the two together.

One theory that tries is called M-theory. M-theory supposes that there are eleven dimensions. Four dimensions are the ones we can measure. Length, width, height and time. The other seven constantly oscillate. You cannot see, touch, feel or hear these new dimensions.

Then there is the theory of the multi-universes. This theory posits that several universes exist and each has its own unique set of laws of physics. Only those that can stabilize, like our own, can continue to exist. This Darwinian approach states that other universes that cannot stabilize fail to succeed.

I'll never forget what a physics professor at the University of Houston once told the class. He said physics is full of fudge factors. For example, everyone knows Einstein's equation of E=mc2. E equals energy, m equals mass and c equals a constant. He explained that such constants usually mean scientists can't really figure out the bridge that ties the equation together neatly so they need to find a number that does it.

I'm not sure how right or wrong my professor was. When I see things science resorting to string theory and multiple universes I believe they may be fudge factors. Scientists are married to the idea of a one theory meets applies to all and might be grasping at straws. Instead of examining and modifying existing theories, they look for ways to wrap them up neatly in one package. Scientifically there might not be a way to test these theories. If scientists can't see other dimensions how do we know they really do exists. The same thing applies to multiple universes. How can alternate universes be observed in order to put the theory to test?

The multiple universe theory reminds of the DC Comics multiverses.

Fortunately there are scientists exploring alternate theories. Some are viewed as heretics while others are gaining support or at least getting some to question current practices.

Science is a constant quest for knowledge. Instead of trying to come up with more dimensions and universes, scientists need to examine what is in front of us and explore the visible and observable. I think one day a brilliant physicist, mathematician, philosopher or someone will make a drastic break through that will turn current ideas upside down.
