Quantum mechanics

What is entanglement means?and how it counter the completion of quantum mechanics??

entanglement means any change in one will affect the other entangled one without any connection inbetween them

Is it means some force of attraction or repulsion is occur between every body in the universe...as like the concept of gravitational force

it is not a force like gravity

It is no longer a possible a "varied" prediction of quantum mechanics. It has been proven experimentally by many groups of researchers conclusively over the years . It is the phenomenon by which the quantum state of a particle disides that of another separated by unimaginable distances . It they are entangled. Which is the result of a close interaction that occurred earlier in time. But still it remains "spooky " how it happens.

but yea no one understands quantum mechanics xD

Yes no one understands spooky action. It is against all our logics. Why is it so. No one knows. All we can say at the presant is that it is true. But how remains "spooky".

when even einstein finds it spooky, then no doubt about us

quantum mechanics is still unproven but it answers many things as einstein said something is there what we are missing.
but with the entanglement we are able to teleport photons for a place to another so can say it just works

I suppose you are contradicting what you are saying since you are saying that quantum mechanics has not been proven but at the same time you are talking about an obvious experimental verification of it. As far as I know all predictions of quantum mechanics has been proven to be true. And it may be better said that our mind/logics cannot interpret quantum mechanics since it is very different from our observed reality.

unproven in the sense 'why it works?'

Sorry for misunderstanding your statement.

As far as I understand, quantum mechanics evolved while trying to account for some experimental results. It is absurd trying to use similar experiments to verify the theory. Please correct me if I am wrong.

By experiments we are not referring to the experiments which lead to the need of quantum mechanics but the experiments which would verify the predictions of quantum mechanics.
