View Full Version : Is there any conflict between the theory of relativity and the quantum mechanics?

I've heared someday that there are some conflicts between Einstein and Plank, but I failed to find any refrences that mention this conflict in a simple way suitable for an amateur, so I am asking for your help.


Thank you very much.

As far as I know the conflict is more like a gap. Relatvity has a theory of gravity.... quantum mechanics doesn't (at least not a fully developed one). Trying to merge the two hasn't been successful.

One significant area of conflict is the question of what's going on inside of a black hole. GR predicts a collapse to a singularity. Quantum theory says no. When people try to use them together they get nonsensical results.

Blacktiger226,
There are some similarities that are more interesting to me than differences. QM limits the information that is availale for scrutiny. This is basic tenet of QM. Likewise, the claim that the relative velocity of light is the same in all frames of reference, therefore the speed of light is always measured the same, using special relativistic techniques, before you measure it. If this isn't a limitation there is no such thing as a "limitation" on any aspect of physical reality.

Taken as a pair then, in this regard, the limitation of knowledge of reality, the theories are the same.

If you want to have some fun, read Einsteins "relativity" (readable book, with evrything you need, and question every claim, every argument to determine for yourself, the essence of the theory. As a contrast, David Bohm's, "The theory of relativity" is on the same readable level, but it gives a little variation in the way it is described.

Having to have the theory defined and taught to you by others turns you into a robot.

Thank you very much everybody, but the problem is that my physics teacher told me that the idea of photons was made by both the GR and the QM, and I am not realy convinced, Is that true?

Well, we have in our syllabus some of the basics of the quantum theory:

1) Light consists of packets of energy (quanta), which are called photons.
Each photon has energy (E=h.v).
2) The mass of the photon (during motion) is hv/c^2
3) The momentum of the photon is hv/c
4) The photon loses the mass when it comes to rest, also it could not be accelerated.
(where v is NU the frequency)

The teacher said that those principles where put by both Einstein and Plank, although I read that there is a conflict between the GR and the QM, that if one of them is right the other must be wrong.

Thank you very much.

The first three statements are not in conflict, since quantum theory and special relativty are not in disagreement. General relativity is of no concern here.

Statement 4 is meaningless - photons never come to rest. They always travel at the speed of light, even though they may lose energy.
