Okay, let's say this is a reconstruction - and I try to ignore the problems which we already have with an "exact shape". Sure, you mean the different statistics for Bose or Fermi particles? Well, in this statistics there isn't any specific information any more, right? Statistics is a big...

Okay, I appear to be too bad in QM... you say it not practical to retrieve the information any more. If I take a sugar cube and eat it, how would you theoretically - if not practically - reconstruct it a day later?

We know that there is no law of conservation for the entropy. It is quite the contrary: If we have a closed system without exchange of heat the entropy cannot get less. It will reach the max. If we have not a closed system but a stream of entropy only into a system, the entropy will increase...

0 apples + 0 oranges = 0 fruit I know a bit dimensional analysis but also I know a bit about the empty set in mathematics. As you might have seen in my post, in the top, this was not about a philosophical discussion if 1 apple +2 oranges may in the end be n bananas. It was about the number 0...

"Sorry, professor, I am not to very convinced by your arguments. I have questions... I learned in math that I do just do things betweens numbers. I learned that there are mathematical objects like numbers or vectors. I learned the rules how to do mathematics between them. As an example, I can...

Sure, okay, but this has nothing to do with voltage which is clearly relative to the grounding. 0V = 0kV = 0GV. I thought this is clear but you are right, I should have been more careful with the 0 and the units.

I stumbled over a datasheet of an old pentode where it says, in the english translation: I thought, wow, I am not sure if I wouldn't have written Ug3=0V instead. I am a theoretician in physics but work more as an engineer and teacher. What happens inside of me seems to be the following: The...

Exactly! Which is the "Copenhagen outcome". Why shouldn't it be different for a QM of gravity? I believe, it should be the same.

Isn't this the picture Schrödinger tried to establish, before the Copenhagen picture was accepted? Now in the gravitation world? Why shouldn't we say that we have a pure wave effect where gravitons doesn't play a role? I think we shouldn't go to the past to save the picture of a wave build by...

Would you say that there is another predictive theory avoiding problems at the Planck scale?

Oh, sorry about the confusion. I wanted to ask: What are the accurate predictions of the Feynman quantum gravity which have been measured so far?

Which accurate prediction has been measured to be true so far?

We'll never find out. One of my favorites in Futurama was (not literally, I can't find the citation) "even the sound in the vaccum was better in earlier times":wink:

True, but if the theory is non-renormizable it can never be used at high energies, or in other words: It does not describe gravitation correctly. Right?

Somewhere in outer space. A mutiny happened on a spaceship. As a death sentence the commanding officer and the scientific officer have been thrown out of the airlock. The commanding officer says: "!!!" The scientific officer responds: "..."
