Thanx, this makes sense. Its interesting that it is so hard to define whats "real", I do understand that something that has energy is real.

1.You make the interference pattern go away, the single photon is "just" a particle 2. The photon behaves as if it goes through both slits and gives rise to an interference pattern, this is because it can be seen as electromagnetic waves, but when you measure/detect the photon, the pattern...

Thanx. But it seems you affect the electromagnetic wave by measuring, the electromagnetic wave is what gives rise to the pattern? Not the QM-wave? Does the measuring affect the QM-wave and this, in turn, affect the electromagnetic wave?

Thanx, I am thinking about the double slit experiment, the fact that the photons does give an interference pattern is due to the electromagnetic field waves, then one can destroy this by measuring the single photon, but this is not affecting the electromagnetic wave, but the quantum wave, so its...

I have read in the included reference that the quantum wave is not real in the sense we mean with for example the electromagnetic waves. This can be inferred when looking at the double slit experiment. It seems that this experiment has been looked at as if the quantum wave as is a real wave...

Can anyone move this to the correct part of the forum? Its perhaps not QM as pointed out. Please keep a less aggressive tone.

Her name is Claudia de Rham, was not that clear from the title of the topic? Why all this drama?

I dont think anyone "knows" what dark energy does, its not proven science fact, its a theory. Do you have to be so agressive? Its just a humble question? I will try to find the lecture ref.

I heard Claudia talking in a lecture about the possibility of gravity having finite reach. This could possibly explain observations of the universe expansion and "rule out" dark energy. How controversial is this? She mentions that another force has finite reach, the weak force...

I have seen this in pop-science, is it correct? Does antiparticles move in the oppisite direction of time? Is it possible to prove this experimentaly? Does it have any practical consequenses? We use PET-scaning everyday, is there anything to consider when working with positrones connected with...

Thanx a lot now I have some reading to do.

I am grateful for all answers that help me understand this matter. One comment seemed unecessary. Maybe I missinterpreted the intention.

Yes, I know my questions are ignorant, but I do learn from this discussion. I will get some reading. Thanx

This is bullying, not nessecary and not science

Thanx, is this true for "particles" like electrons and quarks as well? They are vibrations in quantum fields?
