Why does quantum physics not work with general relativity?

Or put another way, general relativity would be forced to make peace with quantum physics, because the space in which physicists measure the effects of relativity would itself be divided into unbreakable quantum units. The theatre of reality in which gravity acts would take place on a quantum stage.

How do you unify general relativity and quantum mechanics?

Superstring theory, also called string theory, is the current formulation of this ongoing quest. String theory attempts to unify all four forces, and in so doing, unify general relativity and quantum mechanics. At its core is a fairly simple idea—all particles are made of tiny vibrating strands of energy.

What is the conflict between quantum mechanics and general relativity?

In theoretical physics, the problem of time is a conceptual conflict between general relativity and quantum mechanics in that quantum mechanics regards the flow of time as universal and absolute, whereas general relativity regards the flow of time as malleable and relative.

Is quantum physics harder than relativity?

General Relativity is more mathematically difficult than non-relativistic quantum mechanics (which is what most people mean when they say “quantum mechanics”).

Did Einstein eventually accept quantum mechanics?

By 1926, Albert Einstein had become completely unforgiving of quantum mechanics’ probabilistic interpretation of the universe and would step away from it forever. Einstein made this most clear in response to a letter Max Born (1882–1970) had written to him when he said: Quantum mechanics is very impressive.

Can quantum mechanics and the theory of relativity really be unified?

This shows that quantum mechanics and the theory of relativity really can be unified. For almost a century, the two major theories of physics have coexisted but have been irreconcilable: while Einstein’s General Theory of Relativity describes gravity and thus the world at large, quantum physics describes the world of atoms and elementary particles.

Why is it so hard to merge gravity with other forces?

If you go back to the origins, the difficulty in merging gravity with the other forces mostly stems from general relativity being a purely geometric theory — again, that’s in its original form — and all the other forces being quantum, by which I mostly mean they are conveyed by well-defined force particles.

Is space a condensate of the universe?

The scientists have therefore succeeded in bridging the gap from the microworld to the macroworld, and thus from quantum mechanics to the General Theory of Relativity: they show that space emerges as the condensate of these elementary cells and evolves into a universe which resembles our own.

How hard is it to unify electromagnetism and electromagnets?

Electricity and magnetism was unified in the 19th century, and unification of electromagnetism with the weak force followed suit, bringing into play the electroweak force. I’ve been told that unifying these with the strong force is likely to be far easier than unifying them with gravity, albeit still very hard.
