Why we cannot understand Quantum Physics.

The problem is that physicists draw the Quantum Physics
with ‘ math point-particle’ and therefore they ‘kill the picture
of ultimate reality.’
Of course, physicists know very well that the particle isn’t a
math point, but any another model of particle brought difficult
which they could not solve. Therefore physicists preferred
to think about particle as a structureless point
===.
At last from 1968 physicists decided that instead of a
‘point particle’ they will use ‘a string – particle’ and developed
‘ string theory’. The problem is that there are 5 or 6 ‘ string
theories’ in 10 or 11 dimensions .One theory is better than
other one. And they decided to unite them in one
‘ M-string theory’ . This theory is still in a cultivation.
=.
So, now we don’t know what elementary particle is and
therefore we don’t have the Philosophy of Physics.
=.
Is my opinion difficult to understand , is it ‘an unintelligent garbage’ ?

It was realized that the various former string theories were mutually compatible descriptions of an 11 dimensional reality.

You say 'physicists'. The fact is that some theoretical physicists have been working on string theory. Others have been working on other theories. There are a number of candidates for the final theory, and none of them is really well developed.

When I say that none of the candidates is well developed I am exempting QM, and GR. They are both well developed and work extremely well.

And of course it has been a long time since physics considered particles to be point objects. QM has been developed based on the idea that particles are wave functions, not points. In some areas particles can be considered to be points for ease of computation, but there are getting to be fewer of those places all the time.

I am sorry Socratus as the two above have explained your information is almost 20 years out of date.

(http://en.wikipedia.org/wiki/M-theory)

Quote:

M-theory attempts to unify the five string theories by examining certain identifications and dualities. Thus each of the five string theories become special cases of M-theory.


SO there is only ONE string theory now and it is certainly NOT accepted as the mainstream physics view.

Infact it is under seige from QM and the results from the Higgs.

As we said if you care to discuss things we can perhaps explain things because you have got so many basic things wrong.

You might try asking simple questions rather than posting long quotes that are garbled from multiple sources. If you are trying to look like you understand WE KNOW YOU DON'T because you keep making a mess of the quotes.

So your title is wrong YOU may not understand QM but that is not true of science.

Oh for Red and Bill S.

Tommaso has just put up the latest details from ATLAS which includes the WW channel data analysis.

The 126 GEV Higgs has grown to 5.9 Sigma
