@McGentrix,
It matters not.
Einsteins hypothesis was accepted as a total replacement for classical Physics of Newton, Galileo because the classical theory was a "wrong model".
Einsteins model it is claimed, is totally correct for ALL SPEEDS, from stopped right through to light speed.
So there is no excuse now to ever be still using classical physics because the theory has been replaced.
"Close enough" is not good science, an we have computers to do the math for us. Einsteins relativistic equations could even be built into the calculator functions on your mobile phone, but the are not.
Our teacher friend with all that experience and knowledge, with the work of the greatest genius Physicist ever, and the full support of the whole academic community behind him, has quit this discussion.
Why? Because I am so stupid that I cant follow these simplistic ideas?
No, that's not the reason.
He never once even attempted to explain exactly the mechanism, the Physical forces and processes that could cause an object to shrink, only in one direction, and only for a remote observer, not for the observer on the shrinking object. The exact same forces, ( and it must take a force or energy)
must also be responsible for causing the object to gain Mass, (not momentum, that's not Mass, nor is Energy mass) despite te object now having a smaller volume. And the exact same physical force is somehow also responsible for causing the Time, only as seen by the remote observer, to have dilated fir the remote object.
Finally and hardest of all, the shrinking, the dilation and the gain of Mass that actually does happen to the remote object, will give totally different results for every other observer simply on account of the fact that each remote observer has a different relative speed, or even just a different location.
If you believe this, above the much more reasonable conclusion that somewhere Einstein's hypothesis contains a critical error, then you are quite irrational.
This teacher guy, and your Professor have repeated the same end result that I've come across about a dozen times personally, when dealing with academics that claim to possess the superior knowledge of Einstein, yet in every case, (two were Particle Physicists) they end up running away, and none try to address the issues I raise.
Their only defense ends up being that I'm such a moron that its a wonder I can brush my teeth, I'm so stupid.
I actually can brush my teeth all on my own, and I may be stupid, but still I expect that the experts should be able to provide a really solid, full explanation for every aspect of the Theory that has overturned Classical Physics.
(the classical Physics that they still teach, and test you on, and which every scientist and physicist still uses daily. The classical Physics that NASA used to design rockets, and send them into deep space...)
But despite the fact that I've asked and challenged many experts, none has ever even attempted a reply. No books have been written, no Papers submitted for publication.
Education is a big business, and the institutions have a vested interest to keep full and absolute control. They do this because kids are easiest to control when fully indoctrinated.
You can never challenge their authority, or you will get kicked out, fail to get your degree, and have no job opportunities.
And I still never got to move on to all the other problems with Einsteins work.
