What does quantum physics tell us about reality?
A photon is both a particle and a wave until you choose how to measure it. An odd space experiment has confirmed that, as quantum mechanics says, reality is what you choose it to be. Physicists have long known that a quantum of light, or photon, will behave like a particle or a wave depending on how they measure it.
Is there such a thing as objective reality?
A quantum experiment suggests there’s no such thing as objective reality. Physicists have long suspected that quantum mechanics allows two observers to experience different, conflicting realities. Now they’ve performed the first experiment that proves it.
What is reality physics?
Reality is the sum or aggregate of all that is real or existent within a system, as opposed to that which is only imaginary. In physical terms, reality is the totality of a system, known and unknown.
Can there be an objective reality that is the same for everyone?
Yes. Though shrouded in mystery, objective truth exists, and it exists regardless of what anyone or everyone believes.
How does a particle know it being observed?
One way to “observe” a tiny particle like an electron is by detecting its presence via its electric field. That detection necessarily requires that the electron disturbs some part of the the detection device’s electric field if it is to be registered by that detection device.
What is objective reality vs subjective?
We humans are permanently in subjective reality, as are all conscious life forms. Objection — Objective reality must exist independent of subjective reality. Just because we do not or cannot perceive it, does not mean it does not exist.
Is quantum physics difficult?
Quantum mechanics is deemed the hardest part of physics. Systems with quantum behavior don’t follow the rules that we are used to, they are hard to see and hard to “feel”, can have controversial features, exist in several different states at the same time – and even change depending on whether they are observed or not.
Can a person be completely objective?
Researchers from Johns Hopkins University used a series of sophisticated experiments to test a philosophical idea. They found that it is nearly impossible to separate an object’s true identity from the viewer’s perception of it.
Is quantum physics all subjective?
No, quantum physics is not all subjective, nor is it all objective. Humans always inject some subjectivity into what they are doing. There are ways to be more objective. The more objective ones methods are, the more true ones results are.
What is a subjective interpretation of quantum mechanics?
Interpretations of QM that deny the existence of an objective reality independent of our perception are called subjective interpretations. Here are two links about subjective interpretations: Q: Has quantum physics proven that there is no objective reality?
Is there such thing as a shared objective reality in quantum physics?
Though the research has yet to be vetted and published by an academic journal, its findings lend real evidence to the sort of brain-melting ideas that wow physics undergrads – when it comes to the realm of quantum physics, there may be no such thing as a shared objective reality. This article was originally published by Futurism.
Do we need to rethink our notion of objectivity in quantum mechanics?
This experiment therefore shows that, at least for local models of quantum mechanics, we need to rethink our notion of objectivity. The facts we experience in our macroscopic world appear to remain safe, but a major question arises over how existing interpretations of quantum mechanics can accommodate subjective facts.
