virtual particles pop in and out of existence---does it means its creation and destruction of energy ?

Question

if popping in and out of existence of virtual particles implies creation and destruction of energy?what exact difference is between a real and virtual particle?if all real or matter particles can be turned into virtual particles?

Answer 1

Let me start off by saying, this topic is extremely advanced, so when I explain things, I'm explaining them in a very simplified manner. But let's go through your questions and answer them one by one.



> "virtual particles pop in and out of existence---does it means its creation and destruction of energy ?"



Short answer: yes. The answerer named "Who" is incorrect to state that a virtual particle " 'borrows' energy so that it can be created, exists for a short period, then disappears giving the energy 'back' ". Virtual particles have their own energy which is created out of nothing. It is not taken from some other source of energy. Before you start shouting about conservation of energy, let me explain what is going on.



If you didn't know, there is something called the Uncertainty Principle. Amongst other things, it states that the uncertainty in the energy of a particle, multiplied by the uncertainty of the energy at a given time must always be greater than or equal to a specific, positive value. In simpler terms, I mean that the energy of EVERYTHING has the ability to vary back and forth very very slightly. This is an inherent property of everything. Macroscopic objects, like you or me, however fluctuate so minutely that it is not detectable. This fluctuation of energy only has a meaningful result when you look at single particles. If you have a random spot in spacetime, it generally has zero energy, but that zero energy can fluctuation and occasionally can suddenly result in positive energy - in other words, the creation of a "virtual" particle. This energy came out of nothing. However, it is constrained by the Uncertainty Principle, which states that the larger the fluctuation, the smaller amount of time the fluctuation has to exist. Only energy fluctuations which become particles are small enough to exist for any appreciable amount of time. So yes, the conservation of energy law is violated in that energy does come from nothing, but this violation is allowed because it is constrained to exist for a very short amount of time.



However - a virtual particle can actually steal energy from something else and this break away from its constraints by the Uncertainty Principle. When it does this, it no longer has to vanish and can continue to exist for an indefinite amount of time with the energy it stole. Such events happen, for example, with Hawking Radiation.



> "what exact difference is between a real and virtual particle?"



In truth, there is no difference. Both are real particles that actually exist and they can both perform the exact same tasks and have nearly the exact same properties. The only difference is that the virtual particles are constrained to exist for a very short amount of time and after that time is up, they must vanish away and their energy destroyed.



> "if all real or matter particles can be turned into virtual particles?"



I'm not really sure what you mean by this question. Real particles cannot be turned into virtual particles, however virtual particles can become real.

Answer 2

Virtual Particles

Answer 3

The Uncertainty Principle between energy and time means that for very short time periods, there can be a huge uncertainty in energy, enough uncertainty to warrant the production of virtual particles. However, the time periods are incredibly short, meaning the particles are destroyed just as fast, constantly being created and destroyed. The energy is vacuum energy, not normal energy, because it occurs due to the uncertainty principle, appearing and disappearing rapidly out of nothing but vacuum. This does not violate thermodynamics due to the tiny time period involved, no work can be extracted from vacuum energy.



Virtual particles are named such because they cannot be observed directly, only when a physical particle is formed that we can observe them indirectly. Photons are physical particles, but force carrying photons (electric or magnetic fields) are virtual photons, they cannot be observed directly. When electrons orbit in a magnetic field for example, virtual photons in the field are converted to physical photons, the radiation emitted as the electron loses energy.

Answer 4

One has to understand and accept the Virtual Particle theory to justify that.

In physics, a virtual particle is a transient fluctuation that exhibits many of the characteristics of an ordinary particle, but that exists for a limited time. The concept of virtual particles arises in perturbation theory of quantum field theory where interactions between ordinary particles are described in terms of exchanges of virtual particles. Any process involving virtual particles admits a schematic representation known as a Feynman diagram, in which virtual particles are represented by internal lines.

It means what is accepted by the observer as real, if the theory is accepted then yes, it means something very much like what you described.

On question 2, Same as before, if the theory is accepted as truth, yes.

3. One is real, one is imagined or theoretical.

4. In theory, yes.

Answer 5

sort of



The virtual particle "borrows" energy so that it can be created, exists for a short period, then disappears giving the energy "back"



difference between real and virtual? - nothing really



and its quantum mechanics (virtual particle theory??????)

Answer 6

If particles do indeed apparently pop in and out of existence it may be that they come from other dimensions of the universe. They may simply shine on their initial emergence into 3 dimensional space but only for a brief period and seemingly disappear, but they simply become dark. This may be evidence of space having more dimensions than the 3 in which we observe.

Answer 7

You have it backward - a particle that is virtual is converting to energy - as in E=MC^2

Answer 8

Yes they violate the law of cause this is why u cant trust science nowdays they contradict themself and you dont know what to believe
