Physics teachers are teaching mathematical nonsense, not science

A couple years ago, I took a course titled Space, Time & Einstein at the WorldScienceU.com web site.  It's taught by Professor Brian Greene of Columbia University in New York City.  There were things about the course that bothered me, and I started thinking about Time Dilation and how it really works.  There was something in Professor Greene's lecture on "The Reality of Past, Present and Future" (Module #8) that bothered me a lot.  But then I forgot all about it as I organized my thoughts and worked on my scientific papers on "Time Dilation Re-visualized" and "What is Time?"  

Then, while waiting to see if my newest paper on Time Dilated Light will be accepted by a peer reviewed journal, I decided to watch parts of Professor Greene's course over again.

I want to make it clear before continuing that Professor Greene is not teaching anything that other physics professors aren't also teaching.  The only difference is the Professor Greene's course and lectures are on-line where I can easily access them.

I soon realized what bothered me about "Module #8" back then.  Prof. Greene was breaking Time down into "quanta," i.e., into moments, like the individual frames of a movie.  And he was viewing time as a mathematician would view time.  Plus, the lecture concludes with Professor Greene saying that, "What this collectively tells us is that the traditional way we think about reality - the present is real, the past is gone, the future is yet to be - that is without any real basis in physics.  What we are really learning from these ideas is that the past, the present and the future are all equally real."

If you believe that, then you can also argue that everything we see may be equally unreal - from a mathematician's point of view.

Looking over the course schedule, I noticed that Module #3 was titled "The Speed of Light."   That's the subject of my latest scientific paper.  So, I watched Module #3 again.  Wow!  It's total nonsense!    

 
Professor Greene explains that the fact that the velocity of the light-emitting-object (when it is coming toward you or going away from you) cannot be added to or subtracted from the speed of light you perceive is proof that the speed of light is a "universal constant."  It proves no such thing!  It is simply proof that the direction an object is moving does not affect the speed of light coming from the object.  I couldn't remember any of that from when I took the course in early 2014.  Evidently, it had no significance to me then.  Now I see it is just plain WRONG.

But there was even more nonsense to come.  I then watched the lecture on "Time In Motion" (Module #5), which is about Time Dilation.  In the screen capture below, he is explaining how the stationary clock by his hand runs faster than the moving clock off to his right because light bounces off mirrors more slowly when the mirrors are moving while light is being used to measure time.  That is total nonsense, and it is also a demonstration that has very little to do with Time Dilation or reality! 


He was teaching his students that Time Dilation is just "an optical illusion."  He didn't use that term, of course.  He was carefully explaining how a stationary person will view an object as moving while a moving person will view the stationary person as moving.  Furthermore, it is a totally wrong and silly demonstration.  It's twisting the facts to rationalize a belief!  In reality, light would not bounce at angles between moving mirrors, light would move in a straight line and the mirrors would simply move out of the path of the bouncing light!  Plus, if the speed of light is fixed and universal, a stationary light clock would give the same result on Earth as on Jupiter and in empty space, and it would disprove Einstein's theory of gravitational time dilation!

It would have been better if Prof. Greene had used the explanation of how a ball is perceived to move if a child on a jet plane tosses it up and down as the plane moves at 500 miles per hour.  The child will see the ball going straight up and straight down, while some imaginary viewer on the ground will see the ball travel in an arc that covers over a thousand feet laterally between the time the ball leaves the boy's hand and the time he catches it again.  It really has nothing to do with Time Dilation, it only has to do with Relativity, and therefore it is the same as saying Time Dilation is just an optical illusion. 

That is where everyone goes wrong!  They do not think of Time Dilation as a real phenomenon all by itself, they only think of it in terms of relativity!

And, it was really bizarre when I watched Module #7, "Time Dilation - Experimental Evidence," in which Prof. Greene explains how Time Dilation has been confirmed by people carrying atomic clocks aboard airplanes, and he explained how muons exist longer when they are traveling faster.  Professor Greene makes absolutely no mention of gravitational time dilation.  Nor does he explain who was the "observer" when the atomic clocks were flown around the world.  He doesn't put 2 and 2 together.
 

Module #12 was the most absurd of all.  It's titled "The Twin Paradox," and it shows how preposterous the explanations can get when mathematicians try to rationalize and distort Time Dilation to make it fit their equations.  Prof. Greene uses "fraternal twins," George and Gracie.  While George remains on Earth, Gracie goes off on a space ship to some nearby star and then returns.  That's simple enough, but Prof. Greene then explains how neither twin knows who is really moving.  He has Gracie arguing that her space ship is standing still while George and the planet Earth moved away from her, while George argues just the opposite.  Prof. Greene then explains that George is right because Gracie felt acceleration, which wouldn't happen if she had been standing still.  It's an absolutely silly explanation of Time Dilation.  In what universe would a space traveler think that she was standing still while the planet she just rocketed away from must be moving away from her and then somehow it reversed course to come back to her once again?  It's idiotic!

  
It also shows how mathematicians do not care about logic or reasoning.  They only care about how the math works.  The math says that an astronaut can stand still while the Earth moves away from his rocket, therefore it must be possible.  

At several points in the course, Professor Greene pauses to explain to his students that if what he is saying doesn't seem to make any sense, then they should take the version of his course that focuses on mathematics.  

Yes, why not?  After all, in the world of mathematics "garbage in, garbage out" is totally acceptable if the equation looks clever.  Nothing needs to be logical or make sense if the mathematics work.  Science today is about mathematics, not about logic -- or science.

I not picking on Prof. Greene.  He's just teaching the same nonsense that most physics professors seem to be teaching.  As stated above, Prof. Greene merely  put his course on the Internet where I could take it and view the lectures over again.  I should be grateful.  It taught me a great deal, but definitely not what Prof. Greene intended to teach.   

I don't see any way to contact Prof. Greene directly, so I posted a "zinger" question to the discussions for Module #5.  Click HERE to see if you can view it.  It works for me. 

As evidence that other teachers are teaching the same nonsense, here's a video that also uses a "light clock" to explain relativity:


There are probably many similar videos out there.

  1. It's unbelievable how many wrong conclusions you have here.

    1. It's unbelievable that someone would write such a comment without specifying which "conclusions" are "wrong" and what the FACTS and EVIDENCE say are the CORRECT "conclusions." Do you have only PERSONAL OPINIONS?

    2. Since all of your conclusions were only personal opinions, you wouldn't want anything else.

    4. on the bit -> "He didn't use that term, of course. He was carefully explaining how a stationary person will view an object as moving while a moving person will view the stationary person as moving. Furthermore, it is a totally wrong and silly demonstration. It's twisting the facts to rationalize a belief! In reality, light would not bounce at angles between moving mirrors, light would move in a straight line and the mirrors would simply move out of the path of the bouncing light!" -> I think you fail to realize -> IF relativity is true then the light has to move at an angle. i.e. assuming the psotulate of relativity then that is what happens. Then experiments such as Michelson-Morley are referred to and it is deemed that is what physically happens - that light moves at an angle.

    5. Sorry, but I can make no sense of what you wrote. Light moves in straight lines. If YOU are moving at right angles to the path of the light, YOU would see the light moving at an angle, but it would be an optical illusion.

      Delete
    6. I am saying light does "bounce at angles between moving mirrors" according to the relativity postulate, if it didn't then relativity would be violated, AND the empirical evidence supports that. You think "light would move in a straight line and the mirrors would simply move out of the path of the bouncing light" - which is false, and if it were true then would know when were moving which would violate relativity.

    7. You seem to be talking about Mathematicians' view of Relativity, not Einstein's view. The Mathematicians' view is that "all motion is relative," therefore if we are moving relative to one another, I can claim to be stationary and that you are moving, and you can claim to be stationary and that I am moving. That is absurd.

      In Einstein's Relativity, all motion is relative to the speed of light. If I am moving and you are "stationary," I am moving at a larger percentage of the speed of light than you are. The greater the percentage of the speed of light that an object is moving, the greater the MASS will be for that object.

      The Mathematicians' view is just plain absurd, since it says, if you are in a rocket lifting off from the earth, you can argue that you are stationary and I and the earth are moving away from you.

      Such a view ignores the FACT that it takes ENERGY to move things.

    8. Mathematicians' view is same as physicist, and supported by empirical evidence. Energy is relative as well, observers observing from different frames a moving object will assign it differenet values of kinetic energy as per different velocities relative to their frames. So whether you think it "absurd" or not, it doesn't matter because that is the way things are.

    9. In 1921, Albert Einstein said this to the Prussian Academy of Science: "“As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality.”

      I've spent the past 5 year analyzing how mathematicians DISTORT Einstein's theories. Mathematicians DO NOT CARE about evidence. When a moving object hits a "stationary" object, the kinetic energy of the moving object will scatter debris in the same direction the moving object was traveling. That cannot happen if you decide that all motion is relative, and the stationary object was moving.

      When we send a rocket to Mars, the rocket moves away from the Earth. The Earth does NOT move away from the rocket.

    10. Also Einstein said “Since the mathematicians have invaded the theory of relativity I do not understand it myself any more.” https://www.goodreads.com/quotes/78897-since-the-mathematicians-have-invaded-the-theory-of-relativity-i So it just grew beyond him.

    11. That's one way of looking at it. I would say the correct way is that the mathematicians caused things to be so confusing because Einstein's view and the mathematicians' view are totally incompatible.

      Einstein referred to the interpretations by mathematicians as a DISEASE when he wrote to his friend Paul Ehrenfest, “You are one of the few theoreticians who has not been robbed of his common sense by the mathematical contagion.”

      Einstein went to his grave arguing with mathematicians (including many advocates of Quantum Mechanics) over how to interpret his theories of Relativity.

      Delete
    12. Well Einstein did argue about Quantum Mechanics, but I don't know about "grave arguing with mathematicians" about Relativity, nor his arguing over "how to interpret his theories of Relativity" with those mathematicians. Do you have a reference for where he was saying about that. As far as mainstream is concerned they developed Relativity further from where Einstein left it.

    13. Just look up Relativity vs Quantum Mechanics on Google. It's a hundred year battle that still rages. Here's an article on Wikipedia: https://en.wikipedia.org/wiki/Problem_of_time

      That article begins with this:

      "In theoretical physics, the problem of time is a conceptual conflict between general relativity and quantum mechanics in that quantum mechanics regards the flow of time as universal and absolute, whereas general relativity regards the flow of time as malleable and relative."

      It started as a battle between Relativity and Quantum Mechanics, but these days it seems that mathematicians have joined the battle against Relativity. Mathematicians seem to believe that math is the FINAL WORD. If the math works, it is true. Period. But history has shown that the math may work, but there may be unknowns which will disprove the math. Math said that the sun goes around the earth. The math works perfectly. But its wrong.

      Delete
    14. Your understanding of mathematics is false; you say "Math said that the sun goes around the earth. The math works perfectly. But its wrong." -> false. -> the Math says that sun and earth move relative to each other -> that is relativity -> so can treat earth as moving round sun and sun moving round earth because its relative!
      As for the question ""grave arguing with mathematicians" about Relativity, nor his arguing over "how to interpret his theories of Relativity" with those mathematicians." -> you gave nothing about that -> instead you diverted onto the argument between Relativity and Quantum Mechanics.
      So, you are just building a lot of false beliefs one on top of the other!

      Delete
    15. Okay, you are just being argumentative.

      You claim "so [we] can treat earth as moving round sun and sun moving round earth because its relative!"

      On this blog that is listed as the #1 DUMBEST belief in physics. Here's the link: http://oldguynewissues.blogspot.com/2018/02/the-10-dumbest-ideas-in-physics.html

      And the argument between Relativity and Quantum Mechanics IS an argument between Relativity and mathematicians. Mathematicians just argue other things, too.

      So, you are just building a lot of false beliefs one on top of the other! And I really can't waste much more time on this debate if you can't understand that.

      Delete
    16. So, you are dismissing good ideas as dumb, so what (?) There are theories unifying general relativity with quantum mechanics, such as superstring theory -> just academia can't agree with which theory to go with -> so your point of that argument is meaningless -> supposedly it will be settled eventually with more experimentation. As for relativity -> from our perspective on the earth, we can feel stationary and its the sun that rises and sets as it moves across the sky -> hence sunrise and sunset. Issues like this Galileo had to address.

    17. I believe in the scientific method. If experiments prove it wrong, it is wrong. String theory is just a mathematical exercise that can never be verified one way or another. It's a waste of time - except for mathematicians who like to play with such things. It's playing math games. It's NOT science.

      Delete
    18. That's ignoring the physicists trying to find ways to test superstring theory. At - > https://universe-review.ca/R15-18-string06.htm says " By 2007 string theorists have come up with at least 4 ways to put their models to test". You accuse me of -> building a lot of false beliefs one on top -> But its you really doing that, and for a person to point out one thing you get wrong, you then just bombard that person with a massive amount of other things you get wrong.

      Delete
    19. Finding or dreaming about ways to test superstring theory is not the same as actually doing such a test. And claiming that something verifies superstring theory is just a claim, it is not an actual test. The scientific method is used to verify or disprove claims.

    20. To dream up the test comes before doing the test, so what(?) Ideas dreamt up get tested costing millions of dollars at LIGO, LHC etc.

      Delete
    21. Tests are experiments. Experiments determine what is true and what is false. Dreaming about tests is just dreaming. Dreams prove nothing.

      Delete
    22. You are having difficulty understanding that before the experiment comes the dream/idea of what to do. Science/physics is at various stages of theorising leading to experimentation. So, far proposed tests such as LIGO finding gravitational waves and LHC finding Higgs particle have been successful. Before such tests there was proposals for such things as gravitational waves and Higgs particle without them at the time having been tested.
