## Where is the particle before measurement?

Now, suppose we make a measurement and find particle at C. Question: where was the particle just before the measurement ? Answer # 1. **Realist position**.

## Does making a quantum measurement really destroy information?

**Making a quantum measurement of one type of variable really does destroy any prior information about its conjugate variables**.

## Is a quantum state is changed when it is measured?

Quantum physics describes the inner world of individual atoms, a world very different from our everyday experience. One of the many strange yet fundamental aspects of quantum mechanics is the role of the observer — **measuring the state of a quantum system causes it to change**.

## How would you describe quantum?

Quantum physics is **the study of matter and energy at the most fundamental level**. It aims to uncover the properties and behaviors of the very building blocks of nature. While many quantum experiments examine very small objects, such as electrons and photons, quantum phenomena are all around us, acting on every scale.

## What happens when you measure a particle?

**Any measurement of a particle “collapses” its wavefunction**, in effect forcing it to choose a value for the measured characteristic and eliminating the possibility of knowing anything about its related properties.

## Can subatomic particles be measured?

**The mass of atoms and subatomic particles is measured using atomic mass units** (abbreviated amu); protons and neutrons have a mass of one amu, and the mass of an electron is negligible. The neutron and the proton are in the center of the atom in the nucleus.

## Is quantum smaller than atom?

**The quantum world is the world that’s smaller than an atom**. Things at this scale don’t behave the same way as objects on the scale that we can see.

## What is quantum theory for dummies?

Quantum theory is **the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level**. The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics.

## Is quantum realm real?

While **the quantum realm exists in real life**, it’s somewhat glorified on screen, as expected, and theoretically, time travel is technically is possible — at least at a subatomic level.

## What are quantum particles made of?

There are two classes of quantum particles, those with a spin multiple of one-half, called fermions, and those with a spin multiple of one, called bosons. The spin quantum number of fermions can be s = +1/2, s = −1/2, or an odd multiple of s = ±1/2. **Electrons, protons, and neutrons** are fermions.

## Can you go infinitely small?

Newton’s famous “inverse-square law” of gravity, for example, says that the force of gravity gets four times stronger if you halve your distance from an object. **If we imagine particles as points, you can make the distance between two of them as small as you like, so the force becomes infinite.**

## How many dimensions do we know of?

three dimensions

The world as we know it has **three dimensions of space—length, width and depth—and one dimension of time**. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

## In what dimension does God live?

Originally Answered: If God exists, in which dimension is he? In the **10th dimension**, all possibilities are contained. Super strings that vibrate in the 10th dimension are what create the subatomic particles which make up our universe and all other possible universes. It is here where God resides.

## Do humans see in 3D or 4D?

We are 3D creatures, living in a 3D world but **our eyes can show us only two dimensions**. The depth that we all think we can see is merely a trick that our brains have learned; a byproduct of evolution putting our eyes on the front of our faces. To prove this, close one eye and try to play tennis.

## Are there infinite dimensions?

10 dimensions are used to describe superstring theory (6D hyperspace + 4D), 11 dimensions can describe supergravity and M-theory (7D hyperspace + 4D), and **the state-space of quantum mechanics is an infinite-dimensional function space**. The concept of dimension is not restricted to physical objects.

## Can you live in a parallel universe?

Those alternate universes are completely separate and unable to intersect, so while **there may be uncountable versions of you living a life that’s slightly — or wildly — different from your life in this world, you’d never know it.**

## What are the 26 dimensions?

The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3×3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: **4-dimensional physical spacetime plus 4-dimensional** …
