Someone said "The universe is not only queerer than we imagine, it's queerer than we CAN imagine."
I have an IQ in the 120s. I tried to become an astronomer, but only got a B.S. (now over a third of a century old). The graduate work was just beyond me.
Now, I know there are people with IQs in the 190s who are able not just to learn the matter of a Physics PhD., but also devise it on their own. I am not upset that there are people much smarter than me...indeed, I am reassured. Similarly there are people taller than I am. I know there have been many people over 7 feet tall, but I believe the record is just under 9 feet. I imagine a 12 foot tall human is impossible.
So far we do not understand the universe, not even to the extent of having a TOE. But maybe the TOE requires an IQ of 300 to develop. Maybe no human will ever have the intelligence to develop it.
If the universe is queerer than we can imagine, then by definition no one will ever imagine the nature of it, and so be able to propose the TOE.
God/Nature/Whatever is under no obligation to design the universe to our level of ability.

Probably not especially since we don't even have much more than a clue regarding the true nature of more than 75% of what the universe is made of.

Sorry Tom but what is TOE for those of us that don't have a IQ of 120 like me mine is only 119 so please explain what the abbreviation TOE means please .

(you academic types use to many abbreviations , or at least the Americans tend to do that ) for those of us normal people we don't use so many abbreviations , so please explain !!!!

TOE = Theory Of Everything, or that's my best guess.

Standard physics final, pick part A or B. Part A, derive the universe, show all calculations, make no assumptions. Part B Q1 to 100:

Well you are supposed to have a degree in it, why don't you enlighten us?

Nils Bohr, Richard Feynman, Albert Einstein and MANY (I would say all) other scientists cant explain QM.
So why do you think I could?

...I recall one of my early QM lectures - the lecturer came in pick up his pen and started at the top right hand corner of the white board, and proceeded, without a word, to cover the whole board with equations. On finishing he stepped back, made a couple of corrections, and then said "Ladies and Gentlemen, that is all yo have to know to pass this course, but you still won't be any closer to understanding the Universe let alone quantum Mechanics". I passed his course, but still don't understand the Universe or quantum Mechanics....

Remember that we bring in the universe and our day to day reality through our senses. Our brains are actually modeling reality. In some instances there appears to be an understanding and actual control of many of life's scenarios.

However, as things move to the very small, we are driven to invent models that tend more toward convenient fictions. These allow us to manipulate and control what we are working with---electricity is a good example as is Newtonian Mechanics.

Most of so called "Quantum Mechanics" is also easily understood in terms of the fiction we create to explain it to ourselves. In most cases the fiction is successful (Atom and Hydrogen Bombs, spectroscopy etc.) and allows us to understand and control physical things with our version of reality.

The two slit experiment is no longer a great, mysterious duality. Google it and you can read explanations in field theory that explain what is happening in things that we sort of take for being "true" --such as orthogonal variation and oscillation of both the electrical and magnetic fields.

Quantum Weirdness indicates that we need better models. The world is quite complex and hard to truly understand. I like to think that: as time goes on that we are asymptotically approaching "True Reality" The Gaussian Curve never hits zero but it gets close enough for me and the rest of the world to be useful.

I saw an interview with Stephen Hawking on television yesterday. He explained the universe is actually one synthesis and that we are all connected (quantum entanglement..?). He also said we should put humankind back in the centre of attention and lose the old Copernican weltanschauung.

We are the only refutable proof of intelligence in the universe. We might as well use that intelligence and concentrate on the (positive) evolution of it!

I was really glad to see an exact scientist like Dr. Hawking making a statement like that :)

There is Physics. There is Meta-Physics and Philosophy as well.

It is important to recognize the differences and to call out the vague and downright silly notions that are interpreted by the layman as great scientific truths.

Then explain this.
A photon can be in two places at the same time.
And it's not because of the Heisenberg uncertainty principle...
Some scientists believe it's more than 3 spatial dimensions in our universe.

And of course the Many-worlds interpretation.

LOL
I know the feeling. QM scientists call the method "Shut up and calculate".
Even the electro-magnetic world is weird.
Gauss's law for magnetism. rot· B = 0
The rot symbol denotes the three-dimensional gradient operator, and from it the divergence operator is rot·
There are no magnetic monopoles; the total magnetic flux piercing a closed surface is zero.
Easy to rembember but hell to calculate.

Gravity is the best known force in the Universe.
Still we dont know what it is.

Come to think about super-symmetry.
Are there anti forces?
Could that be the reason for the universe expansion?

True.

In my opinion our knowledge would be enormously broadened if all the sciences would work together more often.

Hi William, sorry about the static.
Well to simple laymen like me Philosophy is all about weirdos on weed saying self evident truths like "I think therefore I am". i.e. "if I do then I is, or I wouldn't be". Quite what that has to do with Science and Physics escapes me I'm afraid. Metaphysics of course is more bunkum from the same crowd.

I hope you know that the man who said "I think therefore I am" was Descartes.
He was also a scientist and a mathematician.
He developed math that later Newton refined.
The rest is history.
He died in Stockholm when visiting Queen Kristina.
She was very interested in both science and philosophy.

When I was in college, they had things divided into the Social Sciences(Psychology, English, Philosophy, Art...) and the Natural Sciences(Math, Biology, Physics...). My degree is in psychology, and I'm basically a "soft science" guy insomuchas I don't have the intellect or interest to do higher math which is involved in the so-called Natural sciences, but I do respect the field. Hard science produces "proofs" of things that fields like psychology are still struggling to explain. I think in Star Trek NG, Data had an emotion chip. I don't know if math will ever be able to get that deep to reproduce that level of complexity. I guess what I'm trying to say is, there may be a different discipline of understanding the universe than any of the sciences we currently study, and it will probably grow out of a combination of fields.

So you claim that every single philosopher in this world is smoking weed? Odd, to say the least..

Dr. Hawking was interviewed by a PhD in Philosophy last night, she didn't look like a pothead at all..

Last night was part one of the interview. Looking forward to tonight's part two! :)
