Why do quantum theory and general relativity not fit together?

What is it about quantum mechanics that is incompatible with general relativity? Quantum mechanics is incompatible with general relativity because in quantum field theory, forces act locally through the exchange of well-defined quanta.

What is the difference between general relativity and quantum mechanics?

In general relativity, events are continuous and deterministic, meaning that every cause matches up to a specific, local effect. In quantum mechanics, events produced by the interaction of subatomic particles happen in jumps (yes, quantum leaps), with probabilistic rather than definite outcomes.

Can quantum mechanics explain gravity?

Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics, and where quantum effects cannot be ignored, such as in the vicinity of black holes or similar compact astrophysical objects where the effects of gravity are strong, such as neutron …

Does gravity affect quantum particles?

When it comes to physics, gravity rules pretty much everything we can see in the Universe – it keeps planets orbiting stars, stars orbiting black holes, and, well, all of us stuck on the planet.

Why did Einstein disagree with quantum mechanics?

Einstein always believed that everything is certain, and we can calculate everything. That’s why he rejected quantum mechanics, due to its factor of uncertainty.

Does time exist at the quantum level?

According to quantum mechanics, the answer appears to be “no”, and time appears to be in fact smooth and continuous (contrary to common belief, not everything in quantum theory is quantized).

Can gravity be observed?

Normal matter—things made of atoms, such as planets and stars—reflect light and can therefore be observed with telescopes. We call this invisible mass dark matter since it cannot reflect light. Gravitational effects are only way we can detect its presence.
